Memory timings question?

[Yardstick]

I have to fess up that I have never really got to grips with memory timings and my knowledge doesn't go much beyond an understanding that the lower the CAS latency the better.

I've got a two year old rig (spec below) that I have just given a new lease of life to with an X1950 Pro. However I want to wring as much out of the old girl to make the most of the new GPU. I'm going to try a modest overclock but want to make sure I am also getting the best out of the memory - Corsair Platinum XMS 3200 C2PT CL2. I'm running a couple of 0.5 gig sticks in dual channel but have no idea what the optimal timings might be - can anyone help? I'm not looking to push it right to the limit but do want to ensure that I am maximising its potential at the very least.

Does anyone have any suggestions?

Interesting what say about the CAS timing as the only non 'auto' setting I run for the memory is the CAS latency at 2 - run it like that for 2 years. Thanks for the info - it gives me a nice base to start from.
