what I know is WinXP can take any amount of RAM without giving error, but the performance will decrease once above 768MB.
So, what do you think now??

Windows 3.11 supports 16 Megs in 286 Protected mode, 256 Megs in 386 enhanced mode.
Windows 95/95/ME claim support for up to 2gigs of ram, though it has known problems with systems containing more than 512Megs of RAM.
Windows NT 3.51/4.0/2000/XP all support 4 gigs of RAM, though really only 3.5 is possible, since the other 512K of address space is reserverd for system I/O aka PCI,AGP and other devices.
Windows 2000 Advanced Server support 64gigs of ram by take advantage of the Pentium PRO introduced 36bit address mode. Pentium PRO AKA, Pentium II/III, and was later adopted by the PIV.
