SiSoft Sandra usually tells you. However, you can almost always run CAS3 memory at CAS2, so it probably doesn't matter what kind of memory you have. Go into the BIOS and set it to CAS2 if it isn't set already. Note: if you overclock your FSB, CAS3 memory run at CAS2 will be less reliable.

sandra only tells the spd info and the speed setting you're running at,
doesn't tell anything about the real hardware,
some good manufacturers may put chip part number into the spd,
if you can't see such thing in sandra's spd report,
you've to open the case and look at the ram chips,
write down the number on the chip,
and go to the ram chip manufacturer website to check the decoder.

I bought the K-Byte 256MB PC133 ram and went to their page but there does not seem to be a way to tell weather its CAS2 or CAS3. Can anyone help?

I bought a stick of that K-Byte as well. I highly doubt that it's Cas2. I almost 100% that it's Cas3 just like the stick of Kingston ValueRam that I picked up.

Look for a program called CTSPD, Tells a good info about your ram, Runs in windoze.

Sandra does tell what ram your ram can CAS, its in the MB info.
Sandra also shows a little different (224) where as CPSPD (223), Im OC 5mhz on the FSB.
after I found out I could run CAS 2 on the 256 pc133 I pulled the two extra 128 pc100 out , Got a gain of 100+ points on 3DMark01 go figure.

I can run the pc100 at 115 fsb stable but they will not go to CAS 2.

ctspd also just tells the spd info.

some manufacturers may use cas2 memory and write cas3 into spd to sell it as cas3 memory.
some bad manufacturers may use cas3 memory and write "error" into spd to sell it as PC166 or PC2700 cas2.

you must see the real chip number to determine what kind of memory it really is.
