You may have noticed that when faster memory first becomes available, it comes with a higher latency than similar existing RAM. Why is this, and how does that affect overall performance? Also, when you overclock RAM in the BIOS, you will get much better results if you adjust the CAS latency at the same time. But how do you know what value to enter for CAS? And what if motherboard limitations require that you use a lower-than-specified RAM speed? Did you know that you then get to use a lower value for CAS?
This article will answer these questions, and includes formulas and charts so you can feel confident in your RAM purchase and use the correct settings.
