Iwill P55XUB Memory FAQ

What does PC66 mean?

This is the front side bus (FSB) clock speed of the memory. It is okay to run faster rated memory even if the installed CPU uses a slower FSB.

What does the CL number mean?

Column Address Strobe (CAS) Latency, or CL for short, specifies how many clock cycles the Iwill P55XUB 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 Iwill P55XUB, you do not need to worry about the CL rating. If you are overclocking, then going with a lower CL may help stabilize your Iwill P55XUB motherboard.
