tried already but laptop keep hang.........system is win7 32bit 4gb ram....

Can you try revert back to original configuration?

Hi all. I wanted to share with you guys about 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... (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 

It's 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 type 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.

Have fun!

Hey Sifus,

Can Win7 32bits support 8GB ram originally and without hack ?
Thinking of upgrade the ram for notebook Dell latitude E6410 to 8GB

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

did you means only 64bits are able to detect 8GB ?
