Is it possible to downgraed my OS from vista premium x86 to XP pro x64 bit?

I want to be able utilize the whole or most of the 8gb of memory i have.
What about the Phenom x4 processor i have will it run xp? im sure it will... Just want to make sure before I reformat my HD

Or should i stick with Vista and upgrade to x64 bit version?
 
I myself would go with Vista x64. I went back and forth between Vista and XP for a while but Vista finally won the battle. Good luck with whatever you decide.
 
a new question pertaining to this thread...

Does it matter about motherboards for OS 32 or 64 bit?

Cause it seems when i try to run my os either for XP pro 64 or vista 64 it says not compatible!!
I even try to right click the setup app and change the compatibilty option to windows 2000 from windows95 and i cant for eith er OS disc!
So what do i need to do for my OS to install??

Thanks :)
 
Not the motherboard, the processor. You need to have an processor EM64T compatible (Intel) or AMD64 compatible (AMD).

Run CPUz to see if your processor has 64-bit support (EM64T or AMD64).



And what exactly did you tried to do? Running the setup from windows? That won't work.
You need to restart your PC with a bootable CD/DVD with windows vista/xp x64 in your DVD/CD-ROM, access the boot menu and select the DVD/CD-ROM drive or select the boot order from BIOS settings so the dvd-rom drive is before the HDD.

Phenom CPUs are 64-bit, so you can run 64-bit OS fine. I do not recommend getting 64-bit version of XP as finding drivers for it is going to be a nightmare and chances are some of your hardware will be left without drivers.
 
thanks for your replies and help :)

Im just in the process of erasing my HD...

Just on my roomies comp for the time being :) shhh !
