Topic: For win32 users - a script that allows actual usage of 4GB+ of RAM.... (Read 4055 times)

updated download links...for anyone that may use this.

seriously time for 64bit kiddo.....

Nope, XP and previous it did things a bit differently, alot of the code was hardcoded vs a simple check which can be overridden via kernel patch. So, if theres a way, Im presently not aware.

Any chance to make it work on 32-bit XP SP3?

Been workin on patcher, it now removes testing watermarks as well.

Cuz, Im trying to stretch the life of my 32bit OS long as I can, since there is no inplace upgrade to 64bit. I dont wanna spend more than a month trying to figure out the last 6 years Ive put into my OS install =P

why would you even not upgrade to 64 bit?

For years Ive wanted to find a way to use PAE to allow windows 32bit to actually use 4GB+ RAM...since thats basically what PAE is really for. On modern machines windows nearly always has PAE turned on because DEP(nx bit) requires PAE be used. So, by default most windows 32bit installs actually use the PAE enabled kernel.
But, even when PAE is forced on or is on because of DEP... RAM above 4GB is still locked away and unusable.
After coming across this article: http://www.geoffchappell.com/notes/windows/license/memory.htm

Ive been inspired to get this working for myself. So, Ive successfully been able to patch vista_32 & win7_32 kernels, resign them and boot from them. This has been tested on a couple different machines and works fantastic.
After confirming both kernel types are patchable, I set out to write an autoit script that automates the process on both vista & 7.
So, Ive made my first release of the patch. It basically patches the kernel, creates a cert, signs the patched kernel w/ the cert, modifies BCD to add entry of picking between original kernel & patched copy of the kernel.
NOTE: this is ONLY for vista or 7. Win8 32 I have not tested. XP this patch is not possible.
TO INSTALL: Simply run the exe

TO UNINSTALL: by creating a shortcut to my script, and putting 'uninstall' (without quotes) as an argument, it will remove the BCD entries and delete the modified kernel.

I am posting links to my script, one is the precompiled version(the executable)
The other is the source so you can see for urself what it does.

EDIT: patcher now gets rid of watermarks as well.... yay =)
NOTE: after applying the patch, your system may show "test" mode water mark on the desktop in the corner(s). This is normal. There are guides to get rid of this watermark(by editing user32.dll.mui file). I may make it as part of my script in the future if there is enough demand for it.
