I just got 2 2gb sticks of Balistix Crucial. Can I still fill my last two dimm slots with my old RAM? 2 1gb sticks of OCZ. They are both 800mhz pc6400. The crucial RAM has CL-4-4-4-12. The ocz RAM is 4-5-5. My mobo guide says to use the RAM with the same CAS Latenc. Which number is the CAS Latency? My bios says its the first number, the 4. So far no problems with this setup but ive only had it for an hour or two.
 
You need to check the maximum amount of RAM supported by your motherboard.

And yes, the first number in the timings is the CAS latency.
 
The recommendation for dual channel is two or four identical sticks of ram, and if you can spend the money its the best way to go, however, you would be suprised at the ram combinations that can be used and function. It wont hurt anything to try it out though, either it will work, or it wont work in dual channel, slow down to the slowest module, or in some cases with mixed timings,it might change the latency setting on one of the modules, or your machine wont post. but again it wont hurt anything to try it. just keep your eyes peeled for slow or flaky performance.
