My xps 400 desktop (Dell DXP051 Motherboard) currently has 2 DDR2 512MB 667MHz RAM. I am wondering if it supports a 800MHz RAM. If it doesnt, can it be compatible with my 2 DDR2 512MB 667MHz RAM? But the motherboard will run as fast as it can ,which means it will run as 667MHz even tho the ram supports 800MHz,right? Thank you! Can my xps 400 desktop support 2GB DDR2 PC2-6400 DUAL CHANNEL GOLD ...
