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!

Nice catch there mate, but does it actually physically utilize the 4GB RAM with 32bit edition?

Yes, you can see my screenshot. At the task manager there...

does your pc feels faster?

so the windows is still considered 32bit or 64bit?

if u install the next hardware, u use 64bit driver?

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

bro i tried installing but it doesnt work when i enter the Microsoft Windows [Version 6.1.7600] > 128GB Memory. it leaves me at a blank screen and i will be stuck there. is this usual?

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...

can it work on ultimate version?

It work on every version of windows 7, everyone could try though, this patch merely unlock the OS to use more than 3.25GB of ram, your OS is still 32bit, 32bit program still unable use more than 2GB of ram.
Its just a temporary fix.

And yes some ppl may experience stuck at boot screen cause some hardware driver will have problem, or even BSOD with this 4GB ram patch.

It's already long discussed since Windows Vista...
This patch not really used all your >4GB....
They only show you how much your RAM you have since PAE is activated.
Many patch out there,it's not new on Win 7...
It's the same patch from Win Vista...

Really use up the whole 4 gb ram Or it just display the ram installed in your computer?

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

No, we see 1.16G only, run something memory hungry to show your OS can truly utilize more than 3.25G of ram.
Though windows will annoy you with some "low memory" message as soon as the ram utilization near 80% iirc.

Example this:

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.

nice, it works for me 2 on my win 7 home premium x86. i still keeping the original boot configuration

actually you won't waste any money as 64bit windows can use 32bit windows licence too.

It works. My MacBook Pro 2009 with 8 Gig Ram now shows 7.67 Gig usable in BootCamp. Previously it shows 8G with 2.72G usable in Windows Ultimate. Tried Ramdisk plus which is a hazzle to setup and use. 4G Ram now only RM67/pc is affordable.

That's great

gotta try this soon... thanks

wow!!!
Sounds good!Let me try on it and get back my comment for you
