Lots of you will already know all about this subject. But for the rest of us (and I include myself here) this is a relatively short and coherent explanation of memory latency and how it affects our systems.
I recently got a lesson in memory timing when I had to adjust it to get a system I had upgraded by adding memory to in order to produce a stable and high-performing system. The default timing settings were not stable, whereas overclocking the bus slightly yielded a very fast and stable system.
So, for those of you who are like me and a bit murky on memory issues, I give you this short report/tutorial at The Inquirer.
