CAS Latency

I hope I am wording these questions correctly.

1. How important is it that the CAS Latency of the memory module matches that which is specified by the motherboard?

2. Other than by reading the specs of the mobo, is there an easy way to tell what that specified latency is?

3. Likewise, if it is not displayed on the memory module itself, is there any easy way to determine the CL of the memory? Is there a tool that can do it without booting into Windows?

I have a bunch of old PC100 sticks that I want to utilize in a couple of old machines that I know take PC100, but want to still make sure that it is the exact correct RAM.

Thanks,

PK

 

3 - bios. Not exact, but close. Set it to SPD/auto.

I don't know you need to worry about cas latency. Especially pc100. The mobo should default to the slowest memory settings. I don't think you can tell a difference without benchmarking.
