IS Mixing Cas2 with cas3 bad?

[bigbootydaddy]

im about to pick up some more memory, and i have (2) cas3 crucial 256meg sticks of ram, and want to pick up some cas2, is this bad?
or:

should i "clock" the cas3 ram be cas2, and pick up the extra cas2 ram?
or just stick with cas 3 as i wont notice the difference?

abit vp6 dual 933
768 megs of ram (i have some no name brand im trying to get rid of)

Crucial uses the same 7.5 ns memory chips in their CAS3 and CAS2 SDRAM modules. You can use the MB BIOS to override the SPD setting.

I don't think they do.

Mixing CAS 2 and CAS 3 is not "bad". If you can't get the CAS 3 to run at CAS 2 then you'll just have to run the whole lot at CAS 3.

If you can get the CAS3 ram running ok at at CAS2 then you should be fine with new CAS2 ram,if not well the new CAS2 run will run at CAS3 with your old CAS3 ram.

If you run the sticks at their specified MHz speed, you should be able to run all of them at CAS 2. I have 3 sticks of cheap, generic PC100 CAS 3 memory in my Celeron II, but they have no problems running at CAS 2, so long as they run at 100MHz. Once I overclock to 105MHz or more, they will only run at CAS 3.

BBB,
See my reply in my "IDE Partition" thread.

Try them all at CAS2. If you start getting random errors and crashes, clock 'em back down to CAS3.

BTW, I got almost a 4 fps difference by setting my memory to CAS2 in my BIOS in Quake3 demo001. The cpu speed stayed the same.
