Sounds likes its running in 32bit. Does your Bios say 3.25gb as well as Win?

Once Vista has gobbled it up you can never get it back!!!

Nope it's diffently not 32bit :satisfied

its Vista 64Bit and WinXP 64bit and the motherboard see's 4gb's of ram on the bios screen.

does the full 4gb show at post? or in the bios?

 

[LinkTheHero]

yes but only when memory remapping is enabled and it is enabled

Well Guys i was able to fix the problem by using VistaBootPRO By enableing deduct physical memory and only let it deduct 1mb of ram vista now see's all 4gb of ram on my PC

sounds like some weird bios issue. update that, reset to defaults and then see what happens. the vistabootpro method seems like a fairly crappy solution

bios update -> http://www.sapphiretech.com/en/driverfiles/371.zip

personally i'd get vlite and integrate SP1 into vista and then format. xp x64 is based on the server 2003 codebase, not xp fwiw.

 

[squall_leonhart]

and? so what. that means its more stable then XP.. and Vista... don't make me laugh, emulators have issues on that Game console.

Well i turned off deduct physical memory and set everything to default in the bios and did the bios upgrade and it seems to have work :satisfied Thank You Flow for your help :bouncy:
