[CoreOverload]

I checked the official list on thier site and didnt find the ram i want to use (Corsair XMAS2 TWIN2X1024-6400 DDR2-800 2GB Kit C4)
Can someone tell me if this ram will work, or can suggest one from this webpage http://www.extremepc.co.nz/index.php?cPath=117_119&page=1&sort=3a&osCsid=709fad5959087384c2bb63a0037d0bdc

The rest of the system is a Q6600, xfx 8800GTS xxx edition 640mb and seagate 320gb sata-300. And i wanted to have about 4gb of ram 800mhz

This is my first time building a PC
