4Gb and XP SP2

digitaldreams · 16 Aug 2007 at 14:14

Any experience ?

I've heard that even with 4, windows '32 bit' apps only address 2 Gb. There are /3GB and /PAE switches to include in the boot.ini file yet still the apps may only see 2Gb.

Am I forced to go the Vista route ??

If you decide on Vista, make sure that it is Vista 64bit, not 32bit. If you get Vista 32 bit, you'll have the same problem as with XP32 bit.

At the moment I can see 2.7GB in XP, but going Vista soon.

my pc could see 2.75gig of ram, cpu-z saw 4gig, 3dmark06 2.8 gig... to be honest, most programs saw 2.7-2.8gig.

I have now moved on to XP 64bit and am enjoying 4gig goodness

I'm sure they quote Vista 32 as accepting up to 4GB ram !?

You can install 4gb of system memory but, you cannot fully utilize it all with ANY 32 bit OS. Just as with XP, the memory address allocation space is given to other devices before the installed system memory is allocated space. You cannot fully utilize 4gb of RAM with a 32 bit OS, Vista included. You need a 64 bit OS to fully utilize 4gb+ of installed system memory.

My XP SP2 installation can see 3GB ram. I'm not sure why this is varying between systems :confused:

I have XP SP2 and Vista Ultimate 64 on two seperate hard drives for now....Ultimate 64 see's up to 128MB

Vista 64 installed in under 20 minutes...I was told it would take at least two hours !.

Which 2 systems? And, how much memory does each system "see"?
