XP 32-bit max RAM?

[john10001]

What is the maximum amount of RAM that Windows XP (32-bit) SP3 can utilise?

If you ask MS it is 4GB... really it will only see 3.2GB I think.

Well it can see up to 4gb. But it will reserve some for hardware memory addresses. So depending on your hardware it will be alittle less the 4gb.

From experience, I've seen it see usually 3.5GB.

Windows and applications essentially use the first two gigs, and the rest is allocated to Hardware and the kernel.
