is RAM of different cas latency compatible?

[Fingers]

That's what it says in their FAQ too

Can I mix CL2 and CL3 in my system? (http://support.crucial.com/scripts/crucial.exe/solution?11=010109-0022&130=000979083411&14=&2715=&15=&2716=&57=search&58=&2900=&25=6&3=cl2)

What is the performance difference between CL2 and CL3? (http://support.crucial.com/scripts/crucial.exe/solution?11=000724-0010&130=000964475444&14=&2715=&15=&2716=&57=search&58=&2900=&25=6&3=cl2)

I'm about to purchase some new ram. here's the deal. when I built this computer, I was naive enough to think that it was worthwhile to actually purchase the more expensive ram because ther would be a noticable speed increase.. however, since then, I have seen the light. So my question is, I know what I can mix ram of different bus speeds (pc100 and pc133 for ex.), but does it make a difference if I have 2 sticks of ram... one of them is 128 MB pc100 cas2, and the other is 256MB pc133 cas3?

please let me know... I can't imagine that it would be a problem, but I'm usually wrong more often than I'm right!

thanks

I wanted to know that too when I was buying my memory. I was buying Crucial memory and couldn't find the answer on their site so I emailed them. This is the answer I received:

You can mix CL2 and CL3 memory in the same system! The faster memory module
(CL2) will default to the slower (CL3) speed.

So there you are - it is OK to mix them!
