I had XP 32-bit, I added 2GB of RAM to my existing 2GB. (I now have 4 identical Corsair 800MHZ 1GB sticks at 5-5-5-12)
However when I viewed system info it only reads 3.25GB RAM.
Some people said 32-bit XP only supports 3.25 and I need 64-bit. Luckily I have a copy of 64-bit. (A legitimate OEM copy)
So i did a full format and installed XP 64-bit Pro. However system info still only reads 3.25GB RAM.
The video card is a Geforce 7950GX2 which has 1GB of its own memory on the GPU. The MOBO is a M2N32-Sli Deluxe and I am using a AMD 64FX-62 Windsor CPU. The PC itself is running fine.
Why is only 3.25GB of the RAM being recognised?

Because you have a graphics card with 768 MiB RAM on it.
To allow the computer to address the graphics card memory a hole is opened up just before the 4 GiB barrier (it's also for other things but typically everything but the graphics card needs insignificant memory addressing). This memory hole that is used to address your graphics card's RAM is taken from the main system RAM.
Some BIOS's and chipsets can remap the system RAM that is covered up by the memory hole to be above the 4 GiB barrier but it seems that yours isn't one of them. Though I'd check in the BIOS to see if there is a setting referring to memory remapping that you might try enabling.

you haven't any longer have been given an AMC processor, it relatively is an AMD. MAC doe no longer paintings with AMD it relatively works with Intel till that's an older OSx which grow to be a percentthat won't paintings on a pc. to apply a Linux LiveCD you may boot it up and it runs in memory. you may might desire to open the applying middle and sort interior the hunt field, macutil. click and installation. then you definately might desire to discover each and every of the records linked to the MAC stressful force format HFS and the others and installation them too. then you definately could have the skill to establish the MAC stressful force. there's no longer very lots on the stressful force which you will have the skill to apply with abode windows.

xp is your problem, only sees a little over 3 gigs of ram. Vista 32 bit will see 4 and Vista 64 will see 8

in your boot ini file; add /pae to the boot line
Oh, and as for 32-bit XP - it SEES the 4Gb (this is the maximum addressable memory space for 32-bit, which is why it is called 32-bit) You have access to the full 4Gb but XP only 'sees' the 3.25
The line should look like:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /NoExecute=OptIn /usepmtimer /pae
Oh, you may want to add /3gb as well. This forces the kernel to use 1Gb and allow 3Gb to be used by the applications

Time to look into "Fedora",
the OS that just works !
I used to reinstall winblows every two weeks,
ever since I got Fedora in 2000, I have only reinstalled once,
and it was my fault that time... 7 years no problems
- no viruses
- no file fragmentation
- no data loss
Paying for virus protection is like paying them to make more viruses !

For real security, look into encfs
