Re: Windows XP x64 and 4GB ram

Tech-Archive recommends: Speed Up your PC by fixing your registry

In BIOS:
set "Memory hole Remapping" disable,
BIOS report only 2.5G ram,
windows XP x64 report only 2.5G ram, runs well,
windows Xp 32bit report only 2.5G ram, runs well.

set "Memory hole Remapping" enable,
BIOS reports 4G ram,
Windows xp x64 crashed,
windows xp 32bit runs ok but report only 2.5G ram.

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 ?
