set "Memory hole Remapping" enable, BIOS reports 4G ram, Windows xp x64 crashed, windows xp 32bit runs ok but report only 2.5G ram.
Which BIOS versions have you tried ?
Sometimes, a motherboard maker screws up resource allocation
(memory map) in a particular BIOS release. In which case,
if they figure out how to fix it, another BIOS may have it
corrected.

Are you having the error in Windows XP 32 bit or Windows XP 64 bit?
Windows XP 32 bit can address 4 GB, but only with some tweaking of settings so all the RAM can be used.
Perhaps your W64 install has a problem ?
