Jetway 694CS/VM4 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.

Do I need ECC or non-ECC memory?

ECC memory contains error correction circuitry to correct and fix memory errors. If you are running the computer as a web server, database server or anything mission critical, then ECC memory is the way to go. On the other hand, memory errors are so rare that for typical home use, non-ECC memory is recommended. Non-ECC memory is also cheaper and faster.

What does the CL number mean?

Column Address Strobe (CAS) Latency, or CL for short, specifies how many clock cycles the Jetway 694CS/VM4 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 Jetway 694CS/VM4, you do not need to worry about the CL rating. If you are overclocking, then going with a lower CL may help stabilize your Jetway 694CS/VM4 motherboard.
