I have Nvidia 7300GT 512MB, so no sharing there, i don't have an Intel Chipset. I suppose its to do with the bios, its just my testing machine so its not that important but i was curious to know if that's got to be a problem, it shows fine on vista 64.

I think its a cheap motherboard, bought it a while ago, I've tried doodling around with overclocking before and it was a no go, so i guess it is the bios limitation.

You are using a 32 bit OS. Which means at the most you can address 4 gigabyte of memory. 2^32

However as the main ram isn't the only memory in your computer you have to substract the videomemory and other IO memory from your main memory, which apparently leaves you with 3.25 gb of USABLE memory.

That's it, nothing wrong with your hardware, nothing wrong with windows, pure mathematics.

Use windows 7 64 bit and you can use all your memory. A CPU just sees all your memory (RAM, GPU memory, network controller memory, IO devices) as one big block of memory, in the case of a 32 bit system this block has a maximum size of 2^32 bits which is more or less 4 gigabyte.

No he's not, check what he posted. Clearly says "64-bit operating system".

Mate, i think you didn't read my post...? It is 64bit that I'm using.

hmmm, looked over it, my bad :blush: . In that case ome 32 bit driver probably or indeed bios limitation of 4 gigabyte?

Not even sure if its the bios, I just checked it, and the bios is actually reading as something 4096MB. As i said in my previous post, i remember trying to fiddle around with overclocking and the motherboard is so limited that it doesn't allow one bit of overclocking, whether it would be GPU. CPU or RAM.

What model of computer do you have? (or if you built it, what type of motherboard) and I'll try and look into it.

I'm getting curious about this :D No Core 2 Quad architecture should be based on a 32-bit chipset far as I know.

Since this will probably affect other people in the near future (with RAM being so cheap nowadays), it would be very nice if you if you could try to fix it and post the fix, MFDK.

Yeah will do that.

have you updated your BIOS to the latest version from the manufacturers web site?

Yeah that has been done.

See if there is an option for "Memory Remapping" under the BIOS, it should be enabled for 64-bit OS'es but disabled for 32-bit OS'es.

Radish?

I'm going to have a look at it right now.

I just checked the bios, there isn't such a feature as "Memory Remapping" or anything that has to do with 64-bit.

Okay just looking at the product specifications for this board, is your Integrated Video card (regardless of whether you are using it or not) actually disabled in the BIOS?

Its automatically disabled when I connect my PCI/e. I have to go now but i will report back about this seee if i find a solution.

    • The 2TB Samsung 990 PRO NVMe SSD hits lowest price in over three months

      By hellowalkman · Posted

      The 2TB Samsung 990 PRO NVMe SSD hits lowest price in over three months by Sayan Sen Yesterday, we covered a really good deal wherein you can get a 4TB TeamGroup T-FORCE G50 NVMe PCIe Gen4 SSD for a low price of just $400 with a special discount coupon. That's just $100 per TB, making it a very good offer during these hard times. The deal is still live, so you can check it out in its dedicated article here if you do not want to miss out. Meanwhile, if you don't have that kind of budget but still wish to buy an SSD for a good price, the 2TB variant of the TeamGroup SSD at $280 its lowest price in over three months. Meanwhile, those seeking 2TB but faster performance can check out Samsung's 990 PRO, which has hit the lowest price also in the last quarter or so, as it's on sale for $370 (purchase links under the specs table down below). Thus, you want a faster drive, get the 990 Pro, or you want more capacity, grab the TeamGroup 4TB linked in the first para. The 990 PRO is a PCIe Gen4 NVMe SSD and still one of the fastest drives available today for under $500. Speaking of fast, sequential reads and writes are rated at 7450 MB/s and 6900 MB/s, respectively. The random throughputs for reads and writes are 1400K IOPS and 1550K IOPS, respectively. The 990 PRO is based on Samsung's 7th Gen V-NAND flash, and it too is TLC. It packs 2 gigs of LPDDR4 DRAM cache, which helps the random performance. The endurance rating for this is 1200 TBW (terabytes written), which should be sufficient for most users. The Samsung 990 PRO is compatible with the PlayStation 5, but if you are going to use the 990 PRO on a PC, check out the Samsung Magician app that lets you track your drive's health, update its firmware, customize various settings, and more. The tech specs are given below: Specification TeamGroup T-FORCE G50 2TB Samsung 990 PRO 2TB Interface PCIe 4.0 x4, NVMe 1.4 PCIe Gen 4.0 x4, NVMe 2.0 Form Factor M.2 2280 M.2 2280 Controller InnoGrit Controller Samsung In-house Controller NAND Flash 3D TLC 3D TLC DRAM Cache None (HMB supported) 2GB LPDDR4 Sequential Read (Max) 5,000 MB/s 7,450 MB/s Sequential Write (Max) 4,500 MB/s 6,900 MB/s Random Read (4K) Up to 600,000 IOPS Up to 1,400,000 IOPS Random Write (4K) Up to 700,000 IOPS Up to 1,550,000 IOPS TBW (Endurance) 1,300 TBW 1,200 TBW MTBF 3,000,000 hours 1,500,000 hours Operating Temperature 0°C to 70°C 0°C to 70°C Storage Temperature -40°C to 85°C -40°C to 85°C Shock Resistance 1,500G / 0.5ms 1,500G / 0.5ms Heatsink Patented Graphene Heat Spreader No Get them at the links below: Samsung 990 PRO SSD 2TB (MZ-V9P2T0B/AM): $369.99 (Sold and Shipped by Amazon US) TEAMGROUP T-Force G50 2TB SSD (TM8FFE002T0C129): $279.99 (Sold by TeamGroup, Shipped by Amazon US) Good to know This Amazon deal is U.S. specific, and not available in other regions unless specified.

    • UK to ban under-16s from social media following a six-week trial with teenagers

      By FloatingFatMan · Posted

      And here goes the "Won't someone think of the children" brigade. Get stuffed mate. This has NOTHING to do with making the internet safe. It's about tracking adults, spying on your online activity, and sending the boys around when they don't like something you post. Also, again, parliament have voted TWICE against this, and Starmer is going ahead anyway. THAT is anti-democratic bullsh**. They will use this law to track you, they will use this law to control you, and they will use this law to punish you if they don't like what you do, even if it's legal. And your data? Say bye bye to that. It'll be on the darkweb in weeks. I'm not some rando online. I've been an IT professional for 40 years, many of it in security. I know exactly what this means and what will happen to your data. I do not consent and I will not comply.
    • Windows 11 KB5094126, KB5093998 bugging out Office apps but it may not be Microsoft's fault

      By sphbecker · Posted

      "...but it may not be Microsoft's fault" seems like a reasonable way to tease what is going on without leaving the user with a false impression that an update is the problem. A title isn't a summery, it is meant to entice the user to read the article. It should not contain a misleading premise; which this title does not. You could maybe complain that the first paragraph should have included that detail. The writing style popularized over 100 years ago in newspapers will cover the most important information as soon as possible with details and nuance added later; the idea being that with each new paragraph you have less of the reader's focus.
    • Samsung Galaxy XR arrives in the UK with new AI and enterprise features

      By Fiza Ali · Posted

      Samsung Galaxy XR arrives in the UK with new AI and enterprise features by Fiza Ali Samsung is bringing its Galaxy XR headset to the UK several months after the device made its debut as the first headset built on Google's Android XR platform. The headset was first teased in late 2024 alongside Google's introduction of Android XR before making its commercial debut in 2025. Developed in collaboration with Google and Qualcomm, Galaxy XR combines mixed reality experiences with Gemini-powered AI features, allowing users to interact with digital content using voice, gestures, and visual inputs. While the hardware itself remains largely unchanged from the version Samsung unveiled last year, the company is using the UK launch to spotlight several software enhancements that have arrived through recent updates. Among the most notable additions is deeper integration with Google's ecosystem. Galaxy XR users can explore destinations through Google Maps' Immersive View, receiving AI-powered recommendations and contextual information from Gemini while navigating virtual environments. Furthermore, entertainment experiences have also expanded; users can watch 180-degree and 360-degree videos on YouTube, browse spatial content converted into 3D, and ask Gemini questions about on-screen content without interrupting playback. Samsung is also highlighting mixed-reality features such as Circle to Search, which allows users to identify real-world objects through hand gestures while using the headset's video pass-through mode. Another feature automatically converts photos and videos into spatial 3D experiences. Moreover, the headset now also supports Android Enterprise, allowing organisations to manage deployments using existing Android management tools. Annika Bizon, Vice President, Product and Marketing, Mobile Experience, Samsung UK & Ireland, talked about the device, stating: The headset is powered by Qualcomm's Snapdragon XR2+ Gen 2 platform and features dual 4K Micro-OLED displays. The tech giant says that users can expect up to 2.5 hours of battery life. Samsung also confirmed that Galaxy XR will continue receiving software and security updates as the company works alongside Google and Qualcomm to expand the Android XR ecosystem. Galaxy XR is now available for pre-order and will go on sale on 8 July. Customers interested in trying the headset before launch can visit Samsung KX in London and selected Samsung Experience Stores from 17 June. Finally, the company will also host a livestream on 19 June showcasing the headset's capabilities and answering questions from prospective customers.
