AOpen AK73 Pro(A) Memory FAQ

What does PC100 and PC133 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.

Should I go with Unbuffered or Registered memory?

Go with whatever type of memory is currently in your AOpen AK73 Pro(A) motherboard. Registered memory will have one or more horizontal black chips that are smaller than the memory chips. If no memory is installed, you can go with either type but mixing types is not allowed. Registered memory can give you extra capacity at the expense of extra latency.

What does the CL number mean?

Column Address Strobe (CAS) Latency, or CL for short, specifies how many clock cycles the AOpen AK73 Pro(A) 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 AOpen AK73 Pro(A), you do not need to worry about the CL rating. If you are overclocking, then going with a lower CL may help stabilize your AOpen AK73 Pro(A) motherboard.
