I have a really dumb question, so I will ask it. I currently have 2GBs (4 x 512MB) of Kingston HyperX PC2-5400 DDR2 (667) in my machine now. The processor I am using is a P4 840D XE CPU that runs on the 800MHz FSB.
My question is this, am I holding back performance in any way by using PC2-5400 ram? Should I invest in some PC2-6400 (800MHz) ram now fro future Conroe support?
