ASUS A7A266E Memory FAQ

What does PC1600 and PC2100 mean?

The number is the throughput speed of the memory in megabytes per second. The speed you need depends on what the installed CPU supports. You can also run faster rated memory for future upgrading or overclocking.

What does the CL number mean?

Column Address Strobe (CAS) Latency, or CL for short, specifies how many clock cycles the ASUS A7A266E motherboard must wait before the memory module is ready to deliver the requested memory. The lower the CL number, the faster the access time.

However, the performance difference between CL=2 and CL=3 is so small that you will not notice any degradation in speed. Unless you are overclocking your ASUS A7A266E, you do not need to worry about the CL rating. If you are overclocking, then going with a lower CL may help stabilize your ASUS A7A266E motherboard.
