same guy here tat asked the question. For some of u, after your sys is booted and it says only 90 percent or alittle less is useable, its caues your system is useing that amount u think u are short as direct mem access and its been allocated to resources and stays on reserve for them, therefore it is deducted from your total useable ram so dont get confused thinking it aint all there.

If you don't have onboard video, yes.

It isn't just onboard video.

32-bit has a limit of 4GB RAM, but part of the 4GB of VAS (virtual address space) has to be set aside for use by other hardware, so you will never have access to the full amount of RAM.

64-bit has a limit of 128GB RAM.

And don't confuse the CPU & the operating system. You can run the 32-bit version of Windows with a 64-bit CPU & the limit will still be 4GB. If you run the 64-bit version of Windows with a 64-bit CPU, the RAM limitation is 128GB. You can NOT run a 64-bit OS with a 32-bit CPU.

You're safe with 64-bit, the maximum allowed memory is more than that what your wallet can cover ... 32Gig would not be an issue.

Only 32-bit has got a practical limit, anything above 2 Gig is disputed ... there's hardware and software settings to push the limit, but I would not bother.

You're good with 64-bit, just put as much memory as you can afford, it will pay out in the long run.

I was always under the belief that 3-3 1/2 GB's of RAM was the top for a 32 bit WinXP O/S ? Anythnig over that I was told was a waste of money and would not be used by system ! I have 3GB's of DDR2 RAM in my WinXP Pro SP3 MCE 2005 and I never even get to use of 1/2 that amount no matter how many apps I have open at the same time ?
