could someone please explain to me what cas2 and cas3 is? i think i understand that cas2 is better. is there a program out there that will tell you what cas your memory is? how do you adjust it? i've heard some people say they run the same stick of ram at xxx@cas2 and xxx@cas3. can you choose one or the other or are you limited to what your memory can do? i'm so confused..

I do not remember things well, and often change the meaning of things, but I will give it my best.

There is CAS and RAS, and people often show this as 2-2-2, this means that the CAS is 2, the RAS is 2, and I have forgotten what the last acryonym is.

The lower the CAS or RAS, the faster it is, I rememver someone justifying it isnt a latency, but I have forgotten what it it was

Here are some quotes from FOLDOC:

Column Address Strobe
<hardware> (CAS) A signal sent from a processor (or memory controller) to a dynamic random access memory (DRAM) (qv) circuit to indicate that the column address lines are valid.

Row Address Strobe (RAS)

Si Soft Sandra 2000 will tell you about the CAS of RAM.

You adjust the CAS setting, it is often in the 'Chippest Features' heading in your BIOS
