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,

PKIt is always best to get the RAM that is correct for the motherboard. Period.

Everest Home can identify the RAM characteristics.

PKNo. The bios usually will allow you to load a set of defaults. In some bios it is CALLED fail safe defaults.
