vista doesn't boot with 4 gb ram installed

hi guys, i have 4x1gb 667 mhz kingston ram.........the problem is that vista gives a BSOD when it reaches the logon screen....it works fine in 4 gb b4...but now it does not working.........thought it boots fine when only 3 modules r installed....but when 4 modules installed i can only boot vista into safe mode.......ram modules r absolutely fine as they r working flawlessly in xp......i' dual booting.....plzzzzz help........i tried uninstalling all my device drivers but all in vain.....??????

It wont give the BSOD then

it would boot and detect wrong amount of RAM... but after WinXP SP2, all 32bit os comes with by default their PAE turned on....

but then again it is a possiblility that 32bit wont work good with 4 GB

i'm using asus m2n series mobo..........and i tried installing vista 64 bit ver. also but BSOD comes in it too.........xp 32 bit is working fine.....??????plzzzzzz help

XFX 650i Ultra had a common problem, when running 4 ram module

it used to have same problem

a hardware problem

Till date, I was under the impression that 32 Bit can support a max of only
3 GB. I was not aware of PAE.Thanks to Choto Cheeta, I learnt this today.

ive heard there is some patch from MS to address 4GB or more ram on 32 bit vista.
So first plugin 3 modules, then go to MS site nd dl it nd apply the patch nd then insert the forth module.

normally 32bit vista can address only 3.2GB mem nd if more ram is plugged, either it wont be detected or wud sometimes result in BSOD.

And also flash with the latest bios from asus site. This cud make u boot into vista 32 bit with with only 3.2b detected
