AthlonOC has just released a guide to help users understand DDR Timings and their effects on system performance and stability. They go through each timing individually plus explain how combinations of timings effect your system. Heres a Quote:
"This primer is the first of a series of articles meant to give you a better technical understanding of how your memory interacts with your motherboard. Unlike some of the other memory guides out there, we intend to provide the information in a manner which will allow you to gain the most from your particular motherboard / memory combination. We try to explain the facts with out going into the how and why of it. We leave that to the engineering types who write for Aces and Lost Circuits."
