32 bit cannot use more than 3gig you may be able to get window to see 4gig but task manager will show you that it only has 3gig avalible to use to use more than 3 gig use 64bit windows
32bit can use 4GB, it can address 4GB, so every bit of memory in your videocard, dvdrom etc etc are deducted from the 4GB. In many cases it's around 3,25GB. But you are right, if you wanna use the full potential of 4GB or more, get 64bit version of windows.
I tried this so-called memory limitation fix by using the Win Server 2008 files on Vista Ultimate x86, and it locked me out. I finally had to reformat and start over. I recommend nobody wasting their time with this BS. If you really need to address 4 GB and up; the best thing is to use 64 bit Windows.
at first reboot this tricks worked....even if winupdate, computer proprieties, customize didn't! so i reboot again....and than windows required a new serial to be activated or i would not be albe to log me in! i think this was the step: enter a win server 08 valid key but i haven't it so i restore the original files!
What happens is Microsoft Locked out the ability to PAE more than 4GB on all the Client Version of Windows so idiots will not keep bugging them about BSOD due to the lousy drivers hardware manufacturers coded for small stuff like WebCam etc. Addressable Memory = 4GB worth of Address - Addresses taken up by hardware So you never get 4GB unless you don't have hardware but then what will you be installing Vista on? So don't bother about those silly more than 4GB "cracks" But if you have Server OS it is a different story.
