Maximum ram supported by windows xp

I think it varies by processor/memory controller, and of course, your motherboard when it comes down to it. Then there is that ugly fact that a 2x8GB kit costs around $800 if both your processor and motherboard support it.

Some Nehalems max at 24GB -- a few of the SB processors spec 32GB max. XP-64 will get you 128GB maximum.

The processor don't determine the amount of ram it is determined by the operating system & motherboard as a 32 bit operating system can only use 4 GB where a 64 bit can use as much as the motherboard allows.
 


Sorry -- I'm not very comfortable with this.

The processor, motherboard and operating system all have an impact.
