Windows 7 32-bit with full 4 GB or 8 GB RAM support


Recommended Posts

Are you still talking about PAE? Reading this thread it seems to me that nobody denied the existence of PAE or its ability to extend memory usage in a 32-bit OS under the right conditions, but rather that it isn't practical for consumers using standard consumer hardware because of incompatibilities.

Actually, ShamRocker1 has repeatedly stated that it isn't possible.

Because I can. LoL

My point was what were you trying to say when you did that? I see that you highlighted the word patch, and this was after you asked me what patch I was talking about. Have you actually READ the first post of the thread?

I do recognize the PAE aspect. There is nobody who has given proof of this working. So, I say BS. Yes the concept is there but no actual proof. Good enough for you?

That's better. At least you aren't now repeatedly saying "it won't work" without saying why you think that. Most of your comments in this thread have reminded me of those people who will stick their fingers in their ears and say "la la la la la" when someone tries to tell them something they don't want to hear.

I'd be happy to test it, but my only 32-bit system running 7 only has 1GB in it, and to try to put more in would mean shutting down my main system and raiding the RAM from it.

Right, so that since PAE does work, and since the server editions of Windows (which are virtually identical to the client editions) have fully supported it since 2000, how can you completely discard the possibility that it can be enabled in the client edition as well? Do you have some insight into how memory is initialized in the two editions to make this claim?

Why do you keep avoiding my question? SHOW ME PROOF! Otherwise go away. TY

Well, someone wrote the patch, so presumably they have run it, as have various people who are posting about it, as well as other sites (such as the one linked earlier, dating back years) that talk about how the restriction works from a technical aspect.

You, on the other hand, simply proclaim that it's "BS!" You need to get off your high horse, and recognize that it is very possible that the patch can work, especially when you consider the technical side. It's not some magic feat we're talking about here. Since you have provided exactly zero evidence or explanation for why you believe it simply can't work (a claim you have continually made), while others have theorized that it can and given some technical background as to why, I hardly think you are in any position to tell people to "go away." The truth is that you have no idea at all.

Show me PROOF. All you have done is spread a bunch of crap and have nothing to back it up as well as rework the dialog to suit your needs or agenda.

Most probably would LIKE to go to 64 bit, BUT 32 bit ONLY CPU's still do exist. And obviously 64 bit wont install if the CPU is only 32 bit. And the only way they'll be able to get out of 32 bit, is if they update everything. So, it'll support it

That is true but by the time windows9 comes out, i dont think there would be 32bit only CPUs about... @ the moment i cant see this happen cause and with windows8 ment to be 2012 i would see 99% of the market using a 64bit CPU and with 50% of those people using a Quad Core or higher..

Show me PROOF. All you have done is spread a bunch of crap and have nothing to back it up as well as rework the dialog to suit your needs or agenda.

Of what? I haven't claimed that the patch works, only that it easily could. I have no interest in running it. There's nothing for me to "prove."

You on the other hand keep insisting that it simply can't, with no explanation why. At one point you even claimed PAE doesn't work. You're just being silly.

As for me "spreading a bunch of crap," you'll have to back that up with quotes. Actually, don't, as I no longer have any interest in talking to someone that willfully ignorant.

Go back through the posts.

I have a 32 Bit PC ? 3,4 GHz, single core. And I think it's running fine and fast enough for me. I can't install Windows 7 64 Bit.

I have installed 4 GB of RAM (4x1 GB) ? but with Windows 7 32 Bit I only can use 3.25 GB of RAM. What for I have paid for 4 GB RAM - when I only can use 3.25 GB ?

If I had paid for a 1 terabyte hard disk and could only use 750 GB I also would be angry.

I borrowed from a friend 4x2 GB RAM modules ? and the test shows that I can use all of this 8 GB RAM.

OK ? you are right: With the patch I still have a 32 Bit operating system and any single application can only use 2 GB of RAM. But, hey, Windows 7 is a multitasking system. So I can run several applications to use all of my 4 GB RAM.

And it is even possible that specific applications can use more then 2 GB of RAM. This feature is named "AWE" ("address windowing extension"- see wikipedia http://en.wikipedia.org/wiki/Address_Windowing_Extensions). But this is a Windows API ? so the software must support it.

With the borrowed 8 GB RAM I do this test:

I installed "VMware Player 3" and created a virtual machine with 5 GB of RAM. And this works.

And about driver stability: All drivers that are included in Windows 7 are WHQL certificated. So all pointers within these drivers must be 64 bit able. That's because DEP (data execution protection) and the NX bit. So this driver works fine and with no problems ? even in a 32 bit enviroment. If you use "not WHQL" certificated drivers it's your own risk. Windows 7 warns you to use them. And in Windows 7 64 bit it is even not possible to use "not WHQL" certificated drivers.

If you brought a pre-made system with that much memory and 32-bit Windows preinstalled, then you would have a point. That would be a ripoff. If you go and buy Windows yourself though, then it is your own responsibility to ensure that it is compatible with your hardware. The restrictions in Windows are widely published.

And about driver stability: All drivers that are included in Windows 7 are WHQL certificated. So all pointers within these drivers must be 64 bit able. That's because DEP (data execution protection) and the NX bit. So this driver works fine and with no problems ? even in a 32 bit enviroment. If you use "not WHQL" certificated drivers it's your own risk. Windows 7 warns you to use them. And in Windows 7 64 bit it is even not possible to use "not WHQL" certificated drivers.

Well, if you go back in time, Windows has actually shipped with several drivers that are not PAE-aware and would crash. In Windows 7, who knows, but it's not impossible since the scenario in question would never actually occur unless someone hacked the OS.

The real issue here though, is that most people end up also running drivers that aren't bundled with Windows. This is where the problem could theoretically occur. Windows runs on so many systems that they have to make sure it's as stable as possible for absolutely everyone. This happens at the expense of people like you, but that's the price.

And in Windows 7 64 bit it is even not possible to use "not WHQL" certificated drivers.

They do not have to be certified, they just have to be signed. Anyone can go buy a certificate and sign their driver with it. There are no requirements regarding code quality. The signing requirements exists only to make drivers more identifiable.

A 32bit driver uses 32bit pointers, a 64bit driver uses 64bit pointers, a driver that runs under an OS with PAE uses 36bit pointers, the WHQL "sticker" doesn't mean it'll use all 3 dynamically.

There are no 36-bit pointers. It uses 64-bit addressing. All drivers that are correctly designed have to support this, which doesn't really mean much since there are thousands of devices out there of extremely poor quality.

The main thing to bear in mind with running a true x64 system is that the processes/applications themselves have a wider memory range. 32bit system with PAE will still restrict each process to 2GB. I grant you that many applications are still 32bit however with the push to 64bit we will start to see more and more apps take advantage of this.

I don't understand why someone would still push for a 32bit system, as 64bit systems are pretty new with relevant driver support.

...

Doh, of course, there's no 36bit data type. You'd just use a 64bit pointer and ignore 28bits of it.

And yeah, I've got a webcam that causes crashes whenever apps try to access it, and that's a using the driver that Windows automatically installs for it.

And in most CPU's made in the last decade, they aren't 32-bit either, they are 36-bit.

There are no CPUs with 36-bit registers. PAE doesn't change register sizes. It just adds another level of hierarchy to the page table structures.

A 32bit driver uses 32bit pointers, a 64bit driver uses 64bit pointers, a driver that runs under an OS with PAE uses 36bit pointers, the WHQL "sticker" doesn't mean it'll use all 3 dynamically.

There is no such thing as a 36-bit pointer.

And about driver stability: All drivers that are included in Windows 7 are WHQL certificated. So all pointers within these drivers must be 64 bit able. That's because DEP (data execution protection) and the NX bit. So this driver works fine and with no problems ? even in a 32 bit enviroment.

32-bit client versions of Windows always run with PAE enabled in the CPU. This is what allows hardware DEP / NX to work. This does NOT result in 64-bit pointers magically appearing, and has no impact at all on driver compatibility.

Allowing support for greater than 4GB of memory is what causes compatibility problems, not PAE or DEP.

If you use "not WHQL" certificated drivers it's your own risk. Windows 7 warns you to use them. And in Windows 7 64 bit it is even not possible to use "not WHQL" certificated drivers.

This is utterly false. 64-bit Windows does not prevent you from using non-WHQL drivers. It prevents you from using unsigned drivers. You can sign a driver without going through WHQL. How do you think 64-bit users install non-WHQL display drivers all the time?

Driver signing is done by the manufacturer and has nothing to do with driver quality.

For some background on the complications which resulted in >4GB of addressing using PAE being disabled for client editions of Windows:

Looks like it isn't limited in Windows 2000. Someone should give it a go.

    • Microsoft Weekly: Surface Laptop Ultra, Windows 11 context menus, Build 2026 recap, and more by Taras Buria This week's news recap is here, with Microsoft announcing the new Surface Laptop Ultra, fresh chips from NVIDIA for Windows on ARM, a no-build week, fixes for Windows 11's context menus, gaming news, reviews, and more. Quick links: Windows 10 and 11 Windows Insider Program Updates are available Reviews are in Gaming news Great deals to check Windows 11 and Windows 10 Here, we talk about everything happening around Microsoft's latest operating system in the Stable channel and preview builds: new features, removed features, controversies, bugs, interesting findings, and more. And, of course, you may find a word or two about older versions. At Computex 2026, together with NVIDIA, Microsoft announced the Surface Laptop Ultra, its most powerful laptop to date, powered by NVIDIA's RTX Spark processor. Details about this computer are currently scarce, as Microsoft has only revealed certain parts of its specs. So far, we know that the computer has a 15-inch mini-LED display, a rich set of ports, a powerful processor, and all-day battery life. It also comes with a new wallpaper, which you can already download here in full resolution. The Surface Laptop Studio is not the only NVIDIA-powered Surface, which Microsoft unveiled this week. At Build 2026, the company also debuted the Surface RTX Spark Dev Box, an odd-shaped desktop with a 20-core NVIDIA Grace CPU and an NVIDIA Blackwell RTX GPU with 6,144 CUDA cores and fifth-generation Tensor Cores with FP4 precision, connected via the NVIDIA NVLink-C2C chip-to-chip interconnect for high performance. According to Microsoft, it can run models with up to 120 billion parameters locally without relying on cloud GPU infrastructure. These two new Surface devices are likely to cost quite a lot, and for those who need a more affordable device, Microsoft is preparing the next-gen Qualcomm-powered Surface Pro and Surface Laptop. This week, details about these two devices leaked in plenty of detail. Other announcements at Build 2026 include the following: Microsoft unveils new security tools for IT admins and developers building AI products Microsoft announces Scout, an OpenClaw-powered personal agent for enterprise customers Microsoft unveils MAI-Thinking-1 reasoning and MAI-Code-1 coding models Microsoft announced a new Windows 11 native command-line utility Microsoft unveils Majorana 2 quantum chip, accelerating commercial timeline to 2029 Microsoft believes that AI agents will eventually replace apps through Project Solara Microsoft introduces Web IQ, a Bing-powered search system built for AI agents Last week, Microsoft released a new Experimental build, which introduced a major Start menu upgrade. It now lets you toggle off specific parts of the menu without affecting other features, resize the menu, and hide additional UI elements. We published a closer look here, so if you want to know what Microsoft is cooking without enrolling in the Insider program and installing unstable builds, check it out. Speaking of new features, many users are very annoyed about the way Microsoft delivers them. Recently, a frustrated user shared their experience with gradual rollouts, and even Microsoft engineers admitted there is a flaw in the system that prevents new features from applying properly. One of those new features includes the ability to uninstall AI models in Windows 11 with a single click. Windows 11 is finally getting fixes for its slow context menus. Marcus Ash from Microsoft confirmed that the company is working on fixing Windows 11's context menus. Reworked context menus are going to be faster, simpler by default, and "configurable to what you use most." According to Marcus, Microsoft will share more details soon. Windows Insider Program Windows 11 preview builds, released last week, are now available for download as standalone ISO files. These days, Microsoft regularly pushes new images, allowing users to clean-install its recent Windows 11 preview builds faster and easier. If you want to try the latest Windows 11 features without jumping through the Windows Update hoops, get those new images here. Sadly, Microsoft did not release new Windows 11 preview builds this week. Come back next time. Updates are available This section covers software, firmware, and other notable updates (released and coming soon) delivering new features, security fixes, improvements, patches, and more from Microsoft and third parties. Microsoft is preparing new features for Teams. Later this month, the messenger will receive a new download manager with auto-dismissing notifications, reducing clutter and making the overall experience less annoying when dealing with downloads. Mozilla released Firefox 151.0.3, a new bug-fixing update for the browser. It is a small release, which fixes problems with pasting into text fields and the oversized VPN button on the toolbar. The update is now available for all users in the Release channel. Here are other updates and releases you may find interesting: VS Code 1.123 introduces massive upgrades for persistent AI developer workflows Microsoft OneDrive is getting a simple yet much-needed feature Microsoft faces heat after quietly blocking promised Office features on Apple systems Microsoft resumes forced Copilot app installation on some Windows PCs Browser vendors pen an open letter to Microsoft, saying "enough is enough" Here are the latest drivers and firmware updates released this week: AMD Radeon Software 26.6.1 with optimizations for F1 25: 2026 Season, World of Tanks: HEAT, and various bug fixes. Reviews are in Here is the hardware and software we reviewed this week Steven Parker dropped more mini PC reviews this week. GEEKOM Air12 2026 Edition is a low-power, affordable computer with an Intel Tiger Lake Pentium Gold processor, up to 16GB of memory, and 512GB of storage, costing just $349. It is light, quiet, energy efficient, and has modern ports on the front. However, the front-facing USB Type-C is data-only, and there are some quirks with the computer's memory, so check out the full review. The AMD RX 9070 GRE has been released worldwide, and we published a benchmark review comparing this powerful graphics card to the RX 9070 XT, 7800 XT, the NVIDIA RTX 5070, and RTX 4070. It has solid, balanced performance, plenty of RAM, and low temperatures, but watch out for mediocre ray tracing performance and not the best efficiency. Also, we reviewed the Cuktech 10 Ultra, a compact, high-power charger with four ports and a big display full of various stats. This tiny charger can pull nearly 120W and spread that power according to each connected device's needs. It also comes with a high-quality 240W cable, three power modes, and retractable prongs. The best part? It is quite affordable, just make sure you have an outlet placed in the right spot to benefit from the built-in display. On the gaming side Learn about upcoming game releases, Xbox rumors, new hardware, software updates, freebies, deals, discounts, and more. Do you remember the ASUS ROG Xbox Ally, Microsoft's first handheld console designed in partnership with ASUS? This week, ASUS revealed a new version of the device to celebrate twenty years of its Republic of Gamers brand. The new ROG Xbox Ally X20 features an OLED display, a transforming D-Pad, TMR sticks, and other changes. However, the chip inside the console is still the same. Forza Horizon 6 launched last month to critical acclaim, but the game will soon have a new rival made by those who used to work on Forza Horizon titles. Mike Brown from Maverick Games announced Clutch, an upcoming racing game with a story-driven campaign, deep car customization, and rich multiplayer. The game is coming to PC, Xbox Series X|S, and PlayStation 5 in Spring 2027. The next update for Minecraft now has a release date. This week, Mojang announced that Chaos Cubed will be available on June 16, 2026. In addition, Mojang published a teaser of the next Minecraft movie. A Minecraft Movie Squared has now been confirmed for a release somewhere in 2027. NVIDIA GeForce Now is getting 18 new games in June. Those include Jurassic World Evolution 3, Fatekeeper, GOALS, Gothic 1 Remake, NTE: Neverness to Everness, and more. If you are a Game Pass subscriber, you can also get new games soon: Persona 5 Royal, Starseeker: Astroneer Expeditions, and more are coming to the service this month. Sumer Game Fest 2026 happened this week, where we saw plenty of new games, including Alien Isolation 2, Final Fantasy VII Remake Part 3, Gen Atlas from the Shadow of the Colossus creator, a new Cuphead game in 8-bit style, a new expansion for Mafia: The Old Country, and more.

    • Let's goooooooo! I've been loving the entries so far! I still have to finish Rebirth (things have been busy!)! Excited for this next installment.
    • "Revelation?" I was hoping for this episode to be called "Reunion". Oh, well... In a related note, the Final Fantasy VII compilation has received an EC entry, short for Ever Crisis. For those who don't know, it already had AC, BC, CC, and DC entries, short for Advent Children, Before Crisis, Crisis Core, and Dirge of Cerberus. I hope it doesn't get an FC entry becaude that would be a freakin' crisis.
