In what way does adding extra RAM help PC gaming performance?

<<< My System Summary >>>

  • OS: Windows 7 Ultimate 64-bit
  • Mainboard : Acer FRS780M
  • Chipset : AMD 780
  • CPU : Athlon II X4 620 2.6Ghz
  • RAM : 4096MB DDR3
  • GPU : ATI Radeon HD 5770 1GB GDDR5
  • Hard Disk : Western Digital 500GB WD5000
  • Display: BenQ V2200Eco 22" LCD w/LED backlight
  • Other: 4GB USB flash drive dedicated to Windows ReadyBoost page file
  • Other: CFA633 LCD display unit mounted in DVD drive bay

So at the moment, my system is a pretty decent budget gaming system, except for the RAM. It seems that most people these days have at least 8GB or more. How exactly does adding RAM affect gaming performance?

I was under the impression that if you didn't have enough RAM at some point in the game, then the game would start deferring to the page file, which would make the game's framerate suddenly drop from its normal average to 5fps or less. The game would suddenly start stuttering while it tries to run from the hard drive instead of the RAM. I thought that if you add RAM to your system, all you are doing is preventing this sudden stuttering from happening. And if it doesn't happen in the first place, then adding more RAM isn't going to make a difference, if you already have enough ram that the entire game is loaded and it never uses the page file. Or so I thought.

But I am being told that increasing your RAM is the cheapest, fastest way to improve your average framerate, not just to prevent these occasional stuttering issues. Is this true?

I ask because I am trying to play Arma 2 at a decent framerate (don't worry I'm not playing that crappy DayZ mod that everyone is creaming their pants about). I understand that without prior knowledge of how the game's engine works, this might be difficult to answer, but I am only using it as an example that seems to happen in most games. The game runs fine when I play very small, self-made missions, with very few units and objects. I can play the game at absolute maximum graphics settings and still get an average fps of 50, so I am confident that my GPU is more than enough to play this game. But if I try to play the campaign, or missions with 100 units or more, the game slows to about 10 fps, which I can improve to about 24 fps by lowering the graphics settings. Even if I am not looking at the units (IE they are not being rendered), so I am still pretty sure this isn't a GPU issue.

Do you think that this is the kind of game issue that could be improved by adding more RAM, or is upgrading the CPU really the only way to help the situation (which is what I'm expecting, but I can't afford a new CPU)? I mean, I already have the page file on a 4GB USB flash drive (thats what ReadyBoost does, right?), so I'm not sure if the RAM is the issue here...

Thank you for taking the time to read my long post, and thank you in advance for any replies/suggestions you might have! - moeburn

In general, adding more RAM won't increase the framerate (that's affected mostly by the CPU/GPU) but it will stop the stuttering caused by not having enough system RAM (as the system will use the page file which, since it is RAM, is slower).

In your specific game case, I believe it's the CPU holding you back and not the amount of RAM.

There isn't a game available on Windows that uses more than 4 gig of ram (that I know of) unless it's a bug. In fact, on Windows most games are still 32 bit anyway, which means they can't physically address even 4 gig.

The timings and number of channels are more important than quantity. I only have 4 gig, and I've never once run out of space (I turn off the swap).

That is so wrong.

In the case of 4 GB/8 GB for current gamers, 8 GB of slower RAM is much more important than 4 GB of faster RAM.

Also, many modern PC games have 64-bit executables.

Name a game that needs more than 4gb of ram?

If we're talking Crysis 1/2 or bf3 those games are just fine with 4gb of ram. However they *do* need more than 1.5gb of vram to run smoothly at max graphic settings. More specifically, they need that much vram to run with max textures. Which is likely the problem the OP is running into, not enough vram.

4GB of RAM is fine for most people and most general uses. but i would recommend 8GB if possible since DDR3 RAM is dirt cheap (i got mine for less than $40 in early May (G.Skill 1333mhz 2x 4GB (8GB total)) nowadays and with 8GB your basically future proofed to as anyone with 8GB of RAM will be plenty into the foreseeable future as it gives you a nice buffer so if programs start burning more RAM you will still be OK. but going over 8GB of RAM is pretty much a waste of money if you ask me unless you got some major RAM hog apps as even when i am hitting my RAM pretty good i still don't exceed 3-3.5GB on the high side but i suspect most of the time i am between 2-3GB.

p.s. but as usual.... you need a 64bit OS to use more than 4GB of RAM. even with 4GB on your system i would say it's a good idea to have a 64bit OS as then you can use all of the RAM where as if your on 32bit odds are you won't be using it all since from what i read 32bit OS can only address 4GB of RAM TOTAL and that's counting video card ram etc. so if you got a 512MB or 1GB video card (on a 4GB of RAM system) your basically not using that much of your system RAM as it will only be able to use 3-3.5GB of your system ram MAX, possibly less. but it appears you got a 64bit OS so you can pretty much ignore this part.

Adding more ram might help. If you're like me and have more programs in the background then you're game may not have enough. If you have xfire, teamspeak, steam, and a video playing then you might need more than 4gb. I don't know about your specific situation though.

You could try turning off everything else you can. Anti virus, firewall...everything. See what happens then.

How much memory do you use when the computer first starts up, and then about how much does it use right before you start a game? (Starting a game after normal, everyday use)

That is correct.

4 GB is enough for 80% of modern games to not stutter if you hardly have any programs running in the background.

However, I suggest 8 GB. It's cheap and it means you won't have to consider closing the majority of your background programs in order to stop many modern games stuttering (especially at higher detail levels).

On a 4GB system, turn off your pagefile and play crysis cranked to max @ 1080p

You`ll soon see a BSOD

Define 'fine'. BF3 can use between 6 to 8GB if available and it helps load times and overall smoothness when jumping from server to server. If one has only 4gb minus what the OS uses there will be swapping. A lot of it.

But I'm not sure RAM is the only problem the op has. ARMAII is a very taxing game. It needs a fast CPU, lots of RAM. modern graphics card and so on. You could start the windows task manager and watch how much RAM the game uses, same for the processor. If one of those are often at 100% you have your bottleneck.

I define fine as playable above 40 fps. But like I said, your vram plays a large part in that, too.

If you have extra memory, you can fit more data: EG physics data, textures ETC into memory, and with more memory you have less chance of other stuff having to be swapped out whilst you're gaming, it also means you should get less disk thrashing as things are loaded and unloaded from memory. All of which adds up to smoother running and less stuttering.

I define fine as playable above 40 fps. But like I said, your vram plays a large part in that, too.

But it's easier to bring down VRAM consumption by tuning the settings while large maps with 64 players will always tax the RAM. And seeing how cheap 4GB DDR3 are right now there really is no reason to live with longer load times and occasional stuttering. BF3 definitely takes noticeable advantage of free memory. Even 6GB is cutting it close imo, a friend upgraded from that to 24GB (yeah, that's excessive) and his experience improved considerably.

If you say so.

Argh, I hate it when people say that. It's such a snarky thing to say.

You clearly don't know what you're talking about regarding this topic and we are all (at least, from what I can see) disagreeing with you so unless you have facts to give, please leave the topic.

Yes. I'm not disagreeing with you. It all depends on how much stuttering you're willing to put up with at max settings. But it's definitely playable with only 4gb of ram.

lol - if by "we all" you mean you, then yeah. I'm not sure why most people would be turning off their page file, especially if they only have 4gb of ram. So that is why I replied with "if you say so". Good job getting all worked up over nothing though.

I define fine as playable above 40 fps.

i think most people consider playable around 30fps (as you can still have a enjoyable experience around that if your holding steady around that level) and perfect, as i am sure you already know, is 60fps+

i think once you start pushing around 20-ish (especially into the teens for any length of time) is when it's bordering on not playable. i imagine if you go into the teens for more than just briefly that can definitely effect your enjoyment of a game when it's that low. but if it's only brief it's not the end of the world.

so anything around 40fps is more than playable.

p.s. i think that 30fps example is especially true in single player games as i suspect multiplayer having a high frame rate is probably more important but even in cases like that, around 30fps will still be decent enough to where it won't be a show stopper or anything.

You clearly don't know what you're talking about...

Argh, I hate it when people say that. It's such a snarky thing to say. :D

But seriously, thanks for the replies, everyone! So if I understand it correctly, if adding more RAM were to improve anything at all, it would be the loading times and the occasional stutter-fark (thats what i'm calling it now, a stutterfark), and not the average FPS. Since I almost NEVER experience stutterfarks with texture detail set to maximum (the only time it happens is when I am flying a fighter jet at mach 1 across the map, and it can't load the textures as fast as I can fly), I will assume it is the CPU that needs the upgrade to get Arma 2 running well. And I can't afford a new CPU at the moment. Oh well, thanks again everyone!

You could start the windows task manager and watch how much RAM the game uses, same for the processor. If one of those are often at 100% you have your bottleneck.

Actually, I have a CrystalFontz CFA633 LCD in one of my drive bays, I think it is begging to be used for this purpose. :) That way, I can watch the CPU/RAM while actually playing the game. I'm not sure why I didn't think of that before. Unfortunately, the LCD's control software constantly uses 2-3% CPU (according to task manager) when running, so it might skew the results.

By the way, I just thought I'd add; I have tried all the obvious tricks, like closing all background programs, turning off antivirus, running in abovenorm priority, etc. To be honest, I can't remember the last time I played a graphics-intensive game without closing all the background programs. I actually have two little batch cmd files on my desktop, one is called "start favourite programs", and one is called "nuke everything". They make it much easier to turn off background progs before playing a game, and then to get all those progs running again when i'm done playing. And I don't even run a real-time scanning AV, just a scan on every file downloaded, and a nightly full-system scan while I sleep.

One quick extra question; Do you think the ReadyBoost 4GB drive is helping things at all? As I understand it, readyboost moves the page file to a usb flash drive. So all thats really doing is making the stutterfarks less farked, yes?

On a 4GB system, turn off your pagefile and play crysis cranked to max @ 1080p

Well I run Crysis 2 on ultra settings @ 1080p, and I don't get a BSOD. Are you sure you're fully patched up?

My Crysis 2 is a 32bit binary, so it can't access 4 gig anyway. The most I've ever seen my memory while running it is about 2 gig or so.

I just paid $30 from newegg for 4GB of DDR3, which boosted my system to 8GB, now I do play games and when I only had the 4GB often time, I would be running close to max on RAM and Pagefile, so of course the games responded slow at certain points (such as loading new areas) I have also had games just completely shut down on me, unknown if it was memory related or not, but if you can afford $30 why not add more RAM?

Technically, 32bit binaries can access more than 32bits of RAM if they do careful memory management themselves.

Quite a lot of CryEngine games have 64 bit binaries but as others have said, more ram means not having to close everything else down when playing games. On my box, so long as the game is alt-tab friendly I can minimise games and often forget I've minimised them and then go back to them at will, which is great for people with low attention spans (like me!).

Just to add my $0.02 to the discussion.

With regards to turning off the pagefile, I don't like doing it myself. It can SOMETIMES cause windows to go crazy, and some programs expect it to be there. Personally I run with a 1GB pagefile with 8GB of RAM.

The biggest issue that occurs isn't to do with maxing out the RAM I believe. I think its some legacy from when RAM was scarce, but windows loves to page out RAM whenever it can, so even if you are only using 3 of the 4GB you have, then windows will start paging some areas of memory, and you can run into FPS issues.

For the most part, "casual games", (such as LoL or D3) use around 700-1000MB of RAM, and will generally run fine with 4GB of ram (if you're not transcoding lord of the rings, solving the 102385th prime number, and sequencing DNA in the backgound).

I didn't say Crysis 2, but yea it was up to date when I found out it kills the system with no pagefile, generally when I was causing some big explosions

I don't know why this needs to be repeated time and time again, but there is no valid reason to disable the paging file. It does not increase performance because Windows only pages stuff when it needs to. Let Windows manage your memory, it wouldn't be designed to write a paging file if it didn't think you needed one.

    • In the way that you framed it incorrectly. You wrote: "The constant need to close all browser sessions and wait for a new version to install" There's no "constant need to close all browser sessions". That's factually incorrect. The browser downloads its updates in the background and installs them when you open it again. Silently. And there's no "wait for a new version to install", updates are small and take 2-3 extra seconds AT MOST, if any. If you have an SSD, there's zero extra time. Also, every mainstream browser operates this way. Firefox, the FOSS go-to browser, the default on almost every Linux distro, does exactly the same. Also, you don't need to constantly restart Edge for updates to install, you can completely ignore them and it doesn't even ask you to handle them, it's all silent and automatic. So I don't understand what else do you want.
    • DuRoBo Krono Review: Portable E-Ink reader with great ideas that need a bit of improvement by Taras Buria Phone-sized e-readers are gaining traction these days, with more people treating them as a getaway device to cure phone addiction (or at least they are trying to) or having a more pocket-friendly reader that is easier to carry and hold. The market now has plenty of such readers to choose from, and DuRoBo is the latest addition, a new player that offers a more interesting approach to the idea. The Krono is a $279 e-reader with an interesting twist, which tries to make the device more fun and ergonomic. Here is my review. Disclaimer: DuRoBo provided the review sample without any editorial input or pre-approval. The Krono comes in a phone-sized box with pink accents. Inside, you get the device itself, a short user manual, and a USB cable. The cable is a bit old-fashioned, Type-A to Type-C, which is a bit disappointing. Hot take: I would rather have no cable in the box rather than another Type-A cable that gets immediately thrown into my box full of similar cables I never use. The Krono also has no charger in the box, as it relies on accessories you already own, which is fine with me. Here are the specs: Dimensions 154 x 80 x 9.0 mm or 6.06" x 3.15" x 0.35" 173 g or 6.10 oz Materials Black or White plastic Display 6.13-inch E-Ink Carta 1200, 1,648 x 824 pixels, 300 ppi Touch-capacitive. Dual-tone frontlight. Processor 8-core Qualcomm Snapdragon 690 (QTI SM6350) 2 performance cores at 2.07 GHz 4 efficiency cores at 1.71 GHz Memory 6 GB Storage 128GB, non-expandable ~104GB available out-of-the-box Operating system Android 15 with a custom launcher Connectivity Wi-Fi and Bluetooth Battery 3,950 mAh battery Buttons and port USB Type-C port Power button, Volume button, Smart Dial Breathing Lights Audio Mono Speaker and Dual microphones In the box The Krono, a Type-A to Type-C cable, user manual Price $279 on Amazon First impressions Right off the bat, no, this is not a phone replacement. Do not approach this device thinking it can serve you as a dumb phone to cure your TikTok addiction. In addition to the fact that the Krono has no cellular connectivity, I strongly believe that no amount of extra devices can fix your phone addiction until you put some serious effort into it. The Krono is a phone-sized e-reader, a companion for your phone dedicated to reading without distractions. The DuRoBo Krono is made of plastic with a very fine texture. It is hardly premium, but I also cannot say it feels cheap. The device is also a bit thick, quite dense, and well-built without rattling or cracking. You get to choose between two colors: white and black. The front has quite thick bezels, which is hardly surprising for an e-ink device. These things use front light, with LEDs usually placed on the screen perimeter. While I do not mind thicker bezels, the notably larger chin cheapens the look a little. What I mind is a notable seam between the display and the main case, which, after just two days of use, collected plenty of dust and specks. The back of the Krono is what makes the device stand out. There is a cylinder (DuRoBo calls it the Axis) embedded in the back of the reader, housing three elements: a power button on the right edge, a Smart Dial on the left edge, and "Breathing Lights" on the back. An etched DuRoBo logo sits below the cylinder, and it is the only piece of branding you can find on the device. Overall, the design and materials are very unassuming, but the cylinder with additional control elements certainly elevates the look and makes it more interesting. Other physical elements include two microphones (one on the top edge and one on the bottom edge), a USB Type-C port, a volume rocker, and a single mono speaker. There is no fingerprint reader, so if you want to protect your device, a PIN is your only option. The official TPU case is not the most premium-looking Display The Krono has a 6.1-inch E-Ink Carta 1200 touchscreen display with a resolution of 1,648 x 824 pixels (300 ppi). The display is front-lit, and you can adjust the brightness and temperature from cool to warm. Unfortunately, the Krono lacks automatic brightness and temperature adjustments, and you cannot set a custom schedule for the frontlight. However, you can set it to always enable frontlight so that you can see what is happening on the screen when turning it on in a dark environment. On the bright side (get it?), the front light can get extremely dim so that the screen is barely readable in a pitch-dark room. The front light is also uniform across the screen, with no noticeable temperature gradients. I am very susceptible to uneven front light, and it is very easy for me to notice it, but the Krono is doing a very good job in this area. I also like that the edge shadow is not very prominent and barely visible in the black variant. E-Ink Carta 1200 is not the newest generation (there are Carta 1250 and 1300), but it is still a good display. It supports three modes: Clarity, Speed, and Quality. In Clarity mode, text is very sharp and easy to read, but you trade that for more ghosting, a slower refresh rate, and more artifacts when the display changes images. Speed mode, as the name suggests, boosts refresh rate and reduces ghosting, but fine print and text become more jagged. Finally, Quality mode is only available in Android apps. It has the lowest refresh rate, but in return, you get much better visuals, improved gradients, and more. Like brightness and temperature, you can toggle modes from the control center. It is available when swiping from the top-right corner of the screen (the top-left is for notifications). I also like that the Krono can work as a desk clock when not in use. It has a bunch of screensavers, including horizontal clocks with time, date, and current battery level. The screen refreshes once per minute, and battery drain is extremely low (not even 1% in 24 hours). It is a great use of the technology, and another thing I wish more e-ink devices featured. Smart Dial The Smart Dial is Krono's main party trick. It sits on the left side of the device and serves multiple purposes. You can twist or press it to perform various actions, depending on the current use case scenario. When reading books, twisting the dial flips through pages, and pressing it refreshes the screen. On the home screen, the dial adjusts the brightness, and holding the dial pressed launches voice note recording. Finally, a quick double press launches the DuRoBo AI chatbot. While the dial scroll is not notched, it is very smooth and has haptic feedback that confirms your actions, which feels very nice. As a long-term Apple Watch user, I love the idea behind the dial. It feels very natural and oddly satisfying to use, especially with that subtle haptic feedback. I never liked flipping pages with touch input, and I strongly believe each e-reader should come with some sort of physical controls for turning pages. The Krono has both volume buttons (which also work as page turners) and the dial, so you are free to use whichever you prefer. With that said, the dial is not perfect. For one, it sticks out of the case way too far for my liking, raising concerns about durability and longevity when carrying the Krono around in a pocket (it is a pocket-sized device after all). Also, it has too much wobble, which cheapens the experience and makes it feel a bit flimsy and unsecured. While there are two plastic guards on the Krono's case, they are way too small for any kind of protection. I also think DuRoBo should let users customize dial actions (the only available customization is scroll direction), particularly for long and double presses. Not everyone needs voice notes, and DuRoBo AI does not work without an active internet connection, leaving the long press essentially useless when offline. I do not mind these features, and I genuinely think they are useful, but I would rather have the ability to toggle between screen modes, turn the frontlight on/off, or launch my favorite app. I also agree with people on Reddit asking developers to let users adjust the dial sensitivity. I hope this is something DuRoBo can implement with a software update to make the experience more personalized (it is a Smart Dial, after all) and incentivize users to fiddle with the Dial more often. The Dial is a fantastic idea, so please, guys, improve it a little. As for ergonomics, they are mostly fine, but the dial's position may feel a little awkward and way too high. When I use a phone or a phone-sized gadget, I tend to rest one of its corners on my palm for a more secure grip. With the Krono, such a grip is impossible because you cannot reach the dial even with big hands. You have to lower the reader a bit and hold it like a bottle without any extra support for the bottom edge. Such a grip is not necessarily uncomfortable (the Krono is also light enough for it), but it requires a bit of muscle retraining. Sometimes, I do not bother with the dial and hold the Krono like my phone, flipping through pages with volume buttons, as they are perfectly positioned for my right-hand thumb. Interestingly, when testing the Krono, I would often find myself thinking that a roller embedded in the long plastic cylinder on the back of the device would have been a much more comfortable solution. There is a free idea for you, guys. Software The Krono runs Android 15 with a very minimal launcher on top. The home screen presents you with a list of apps, a scrollable list of widgets, and your user profile. Widgets can display time, calendar, or recent books for quick access. You can also add or remove apps from the home screen to keep the most useful stuff around without tapping "Apps." I like this minimalistic approach; it looks clean, easy to understand, and light. I understand that some may find the list of all apps way too clean, but fortunately, DuRoBo lets you switch to traditional icons. The reader also has a bunch of preinstalled apps: Read: The default app for reading. Browser: A Chromium-based browser. Files: A simple file manager. Music: A simple music player. Spark: A voice recorder with transcription support and AI summarization DuRoBo AI: A built-in AI chatbot. Transfer: An app for file transfer over Wi-Fi. If that is not enough, there is the Google Play Store, where you can download all the extra apps you need, alternative readers, podcast apps, chatbots, and more. DuRoBo is not trying to give you an all-in-one device. The standard software experience is quite minimal, which makes it easy to approach and learn. The standard reader supports EPUB, EPUB3, AZW3, MOBI, PDF, TXT, DOC, and DOCX, which is more than enough to let you read most books without third-party software. As for customizing the reading experience, you can select one of five built-in fonts, adjust size and thickness, adjust margins and spacing (only three variants for each), change text alignment and direction, toggle the reading status bar, and switch to dark mode. There is also text-to-speech, which utilizes Android's default TTS tech. While I like the simplistic approach, I cannot help but feel DuRoBo could have made the built-in reader a bit more customizable. However, I am not going to bog down on this, as you can always install any other reader you prefer using the Play Store or by sideloading an APK. Getting books to the Krono is very simple. Given that the device is an Android smartphone without cellular connectivity, you can transfer files via a USB Type-C cable, download them using the built-in browser, share them over Bluetooth, or use cloud storage. My favorite was the built-in Transfer app. It is simple, reliable, and very well-designed. I was surprised by how well-designed the web portal is. It is fast, pretty, and properly categorized. Well done! Once you have your books loaded, you can highlight or underline text, add annotations, bookmark pages, check the table of contents, and ask AI about the selected text. Unfortunately, the Krono has no built-in vocabulary, but again, that is something a third-party reader could fix. Overall, the built-in reader is light and snappy, with just the minimum amount of features for a regular user to enjoy reading books. The Krono has no built-in reading tracking, so stat nerds will have to look for third-party reading apps. However, you can set a daily reading goal, and the reader will notify you when you reach it (for example, one hour). You can also set a reminder to read at a certain time, and when the time comes, the Krono will light up its back LEDs and unlock itself to nudge you. Other than that, the rear LEDs do nothing, not even showing charging progress, which is an unfortunate misopportunity if you ask me. Quirks aside, Krono's Android runs quite snappily and bug-free. Early reviews of the Krono criticized its Android 13-based software quite a lot, but now, the reader runs Android 15, and its software has fixed plenty of initial complaints. I never experienced any issues with built-in apps. AI attempts The DuRoBo Krono comes with a built-in AI chatbot. There is no information on what model powers this thing, but the system says it was "trained by Google." You can launch the bot from the app list or by double-pressing the dial. It works just like any other chatbot, and you can ask it anything by typing or using voice input. The AI saves your chats, and you can rename, export, or delete them. DuRoBo AI requires an active internet connection, and it does not work offline. Its reach and capabilities are also limited. You can only chat in the app and use it in the reader app as a makeshift vocabulary. However, the implementation is kinda awkward. You can only send a selected portion of text to AI without giving it any requests or instructions. I highlighted the word "dumb," and it apologized to me for not being useful. You also cannot ask follow-up questions or send the generated response to a separate chat. The chatbot is also slow, even with fast Wi-Fi, making the overall experience quite frustrating, which makes me again wish for the ability to remap the double press to something else. Spark, the standard voice recording app, also uses AI for note summarization and transcribing. Neither feature works offline, unfortunately. Spark records notes up to 30 minutes using Krono's dual microphones, and you can rename or export notes. Transcription quality is decent, and the speed is alright, but you can find much better solutions in the Google Play Store. What I like about Spark is that transcribed notes are not locked, and you can always type more to elaborate on your ideas, which is handy. Overall, I like that the Krono is not shoving AI down my throat, but to be honest, there is really not that much to shove. AI features here feel raw and need improvements to be more useful. Battery Life Like most E-Ink readers, the Krono has fantastic battery life. Even with a clock as a screensaver, its standby power consumption is incredibly low. And when in use, you can get weeks of reading on a single charge. Without the front light, my unit never sipped more than one or two percent of battery during a one-hour reading session. It was nice to see plenty of battery-related settings. You can limit charging at 80% to protect battery health long-term, check the number of charging cycles, manufacturing/first-time use date, battery health, and the maximum capacity. Additionally, the Krono lets you select what hardware remains enabled when sleeping. This lets you keep Wi-Fi and Bluetooth on (say, if you want to receive notifications, for some reason) and keep audio playing when locked. Turning these features off effectively eliminates any standby battery drain. I left my Krono sitting for 24 hours with a clock screensaver on, and it did not drop a single percent. The pretty big 3,950 mAh battery justifies the device's thickness and ensures you do not have to charge it for long periods. Speaking of charging, it is capped at only 10W, which is a bit disappointing, as getting such a big battery to 100% takes a notably long time in the era of super-fast charging smartphones. DuRoBo Moodi The Moodi is a standalone, optional accessory for your Krono. It is a wireless remote with two customizable buttons that you can use to flip pages, control media, or scroll webpages. The accessory connects via Bluetooth. Despite having a built-in rechargeable battery, it is extremely light. While the Moodi's shape and form factor is not what I would call particularly ergonomic, it is not uncomfortable to hold and use. The Moodi comes with six removable magnetic buttons with various smiley faces. Buttons sit securely, and they have nice-feeling, albeit a little loud, clicks. It is a cute touch that adds a little more fun and character to the device. There is also an accented power button and a single status LED. The latter displays charging status and connection mode. The Moodi supports three modes: Reading: Buttons work as volume buttons, allowing you to flip pages in the built-in reader or other apps that support page turning with volume buttons. Media: Buttons work as skip forward/backward, which is useful when listening to audiobooks, podcasts, or music. Scroll: The third mode lets you scroll pages in the web browser or any other application The Krono properly detects the Moodi and presents you with an on-screen guide when you connect it for the first time (it also displays the battery level). However, you can only change modes by holding both buttons for a few seconds. It is also worth noting that the Moodi works with other devices. I connected it to my iPhone and it let me adjust volume or control media playback. Sadly, the scroll did not work, so you cannot use it to waste time scrolling TikToks. Overall, the Moodi is a cute little accessory, which I can recommend for those who read a lot. It is very useful for remote page flipping when you do not want to burden your hands by holding the Krono all the time. I only wish DuRoBo included a lanyard for the built-in loop. As for the battery life, after using the Moodi for a few days, I only managed to drop several percent of its 90 mAh battery. Despite the small size, it is rated for weeks of use, which is pretty impressive. At $35.99, I cannot say the Moodi is a must-have accessory, but I see the appeal. I prefer using the Krono with its Smart Dial, as I rarely read for more than 40-60 minutes in one sitting. However, if you have a stand and like reading for long periods, the Moodi is the right thing to have. It is a bit more expensive than regular page flippers on Amazon, but it is on par with similar products from Kobo or BOOX. Plus, it has a little more fun to it with removable buttons and better integration into the Krono. Conclusion At the end of the day, DuRoBo Krono is a nice pocket-sized e-reader. Its software focuses on the main things without trying to be everything at once. The smart dial idea is unique and great, and I wish more manufacturers had something similar in their devices. The display is also good, with an even frontlight and "always-on" support. I did not notice any deal-breaking issues with the Krono. However, you can feel that the idea needs some improvements, such as a slightly stiffer dial in a more ergonomic location, perhaps a little more premium materials, and better software customization. I hope the company won't give up on the idea and improve the dial and ergonomics in the second generation.

    • In what way is any of what I said incorrect? To install an update you need to close all browser instances, upping it from once a month to once a fortnight is an inconvenience for users. Particularly when updates don't offer functionality that users want (notably copilot). Security updates should come as they are needed, not on a release schedule
