Hi all. I wanted to share with you guys regarding a patch to let Win 7 32bit support > 4G RAM if you really don't want to spend money and time to reinstall a 64bit OS on your PC...

So, recently I have also upgraded my PC to 4G of RAM. With Win 7 32bit (6.1.7600), I have looking around some way to bypass to 32bit Windows 7 limitation. It works... (And it is from Russian ) And I would like to share with you all...

*It's a kernel patch, that allows your 32bit Windows 7 support upto 128GB of RAM

*Some people said it was quite risky? But I think it's ok... So don't proceed if you scare your system became corrupted.

Some antivirus will detect it as a virus, but my Kaspersky 2011 doesn't detect anything. So disable your antivirus first before you proceed.

Step 1: Click the Big button... although you dunno what is it.


Step 2: Press Y, after that it will automatically restart.


1. After Patch, you will have 2 entries to your Windows. One is your original one "Windows 7", another one is "Microsoft Windows [Version 6.1.7600] > 128GB Memory", select > 128GB mode.

2. If you always be prompted for those 2 boot configuration. You can go "msconfig" at the start menu select "Boot" then change the Timeout to lower duration...

3. You can also delete the original boot configuration if you were satisfied with it, but it is not recommended.

4. If you get Watermark "Test mode", type "mcbuilder.exe" at start menu then enter. Restart and it will be gone.

Enjoy your Win 7 32bit with no memory limitation!

I use 32-bit driver & apps. Yes, feel faster

It should continue boot up. By the way, what version of win 7 are you using? Ultimate?

If cannot work, then select the second one... Go to msconfig > boot > then delete the "Microsoft Windows [Version 6.1.7600] > 128GB Memory" selection.

Sorry if cannot work But I tried is ok...

For me, it's utilize all my 4GB RAM, you can see my Task Manager there. There's no cheating.

Now I tried stress using up all my 4GB... Leaving 320+ MB free only. I am running, Red Alert 3 Uprising, Resident Evil 5 & the memory stress utility.

I can't stress all my 4GB using the memory stress utility because it has limitation 2GB only. So I added 2 more games to stress my memory.

I think the 2shared.com website deleted my file. Please go to the original website I posted to download it. TQ

I already tried running games, stress until left 300+-MB... Working perfect.

You check properties -> Computer if you have 4GB RAM, you should able to see (4GB usable right)? To clear it. Go to the start menu search type: mcbuilder.exe and then restart your PC.

Can you try revert back to original configuration?

Currently I don't know... LoL

Please visit the forum I posted to download the patch. IDK why did it removed my download link. Thanks

So far my Windows running perfectly since this year February. (At the time I patch it after format)

--If anything goes wrong, you can simply revert back to original boot configuration and delete the patch through msconfig.

Too bad then. The patch should works fine after fresh format. Because I do like this.

Yes, Win 7 32bit does able to detect/support up to 8GB RAM, but you will only have 3.xxGB usable lor...

64bit Windows can fully utilize it but 32bit Windows cannot. The patch can do a fix on the 32bit Windows to utilize all available memory.
