It is my understanding that the CPU can use all 4GB of memory, but windows XP limits is memory use. I also read that window XP64 does allow the CPU access to the full 4GB of memory. Is this correct???
 
Windows XP allows up to 4GB of RAM, and i believe that Windows Xp x64 allows around 260GB of RAM.
 
NT-2000-XP 4gbs
2000 seriers server 16gbs
windows data center 64gbs
windows XP64 16 Terabytes
windows 98, know theres a patch for 512 mbs and up, but dont know how far it goes
 
The maximum any Ai-32 archetecture can support is 4gb of ram. (a 32 bit processor with a 32 bit address bus, can deal with 4 million addresses.)
(As can WinXP)

"The AMD64 has (initially) 48bit virtual memory address. and 40 bit physical memory address. So in practice, Athlon64 chips can talk to 256TB of virtual memory (physical memory, plus hard risk space) and onyt 1,000GB of RAM.

Which is still a hell of a lot!!

(and as the pentium 64bit range is based on the AMD 64 achetecture, it will follow the same rules.

Windows XP 64 wil support a maximum of 32GB of RAM and 16TB as a virtual address space.


Things are gonna get a WHOLe lot bigger, (and faster) in the months and years to come. :)
