Not to add to the pile too much, but thanks M!tch for the info. This was exactly what I was looking for. BTW, what is DDR2 and DDR3?
DDR2 and DDR3 are newer versions of DDR. There clocked at higher speeds than DDR.
DDR2 is a poorly-designed architecture designed to replace DDR. It's main high point is a lower operating voltage than DDR (this is good for both temps and notebook power consumption). The biggest problem with DDR2 is that you need to hit around DDR2-667 before the superloose DDR2 latencies are overrun by sheer bandwidth, performance-wise. They've been refining the specification, though, and DDR2-533 isn't quite as pathetic as it used to be.
DDR3 is usually seen marked as GDDR3. I'm not sure if it's based on DDR2 or just riding the name, but it's currently only to be found on graphics cards. I've heard talk of a GDDR4 but know very little about it. DDR3 and XDR are teh current frontrunners to replace DDR/2 on the desktop. As far as performance is concerned, the tea leaves suggest that XDR may be the better choice. Unfortunately, that's a RAMBUS technology. So all hail DDR3!
I didn't make it!
Im just cureos, but my Pc accepts a few types of RAM and they vary in MHz, would the one with the highest Hz have best performance?
As of now the best I believe is 533MHz. check whether your PC supports it or not.
