ram and os bit choices in a 750a sli Mb

Specs: Windows XP
Greetings, I have a older xfx 750a sli nforce MB. It has 3gig of ddr2 pc 6400 800mhz ram in it atm. I'm using windows 32 bit xp, wanting to upgrade to windows 7 64 bit with 8 gigs of 1066 @ 2gig per chan. I mainly use this computer for a web browser and a warcraft gaming rig. My old gt9800 video card crapped on me so I ordered a EVGA 1gig gtx 550 ti. I have read that the 1066 ram can be tricky to install and that you have to mess with bios setting. If i stick with the 3gig of 800 ram i will only install 32 bit windows 7. Was wondering since wow is a 32 bit program if there would be lower performance running it on a 64 bit OS since it has to convert wow. My cpu is a older amd phenom 2.2 gig 4 core and i have a 6-700 watt power supply. thanks

The problem with a lot of DDR2-1066 RAM is that it usually requires high voltage. I don't know why unless it's really just overclocked DDR2-800? DDR2 that conforms to the JEDEC standard runs at 1.8v - it doesn't matter if it's DDR2-533, DDR2-667, DDR2-800, or DDR2-1066. Looking at newegg, all the DDR2-1066 runs at 2.0v, 2.1v. 2.2v, or 2.3v, except for the Crucial RAM. Of course, it's the most expensive at $80 for 4GB (2 x 2GB). Is it worth spending $160 for "outdated" RAM when for about the same price, you could buy a modern CPU, modern motherboard, & 8GB DDR3-1600?

If the system does support 8G then it may allow you to install 64 bit. You need to go to the Windows 7 compatibility site to see if all your other apps and hardware is fully supported. Many common ones are not.

Text, talk, drive...CRASH.

Hang up and drive @#$%^^
