best way to over/underclock

[GuiltySpark343]

So I'm using BFGMiner on a Win7 x64 platform and two 7970 cards. My question is, is it better to use the BFGMiner CLI to change GPU core/memory clock settings and voltages, or is it better to use a dedicated utility such MSI Afterburner?

Seems like BFGMiner is the easiest way to do it. I can't think of a reason why using MSI AB would be any different than BFGMiner when it comes to stability or the degree to which I can undervolt/overclock core/underclock memory.

Thoughts?

I personally only OC when I'm mining and then keep my clocks at default when I'm not mining.

CGminer makes this easy with the --gpu-engine and --gpu-memclock flags.  If you hit "q" to quit cgminer it should put the values back to their original ones (if I'm not mistaken).

I also have a hotkey profile setup with the Catalyst control center in the Performance/Overdrive section to load my default clock speeds quickly.  Ctrl+Alt+N seemed logical.

I used to use sapphire trixx, but now i just use cgminer

I have been using Trixx and I never realized cgminer can OC on its own , thanks

Use catalyst?
cos if you oc too much the driver crashes.
