Title: best way to over/underclock Post by: GuiltySpark343 on April 20, 2013, 02:00:12 AM 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?

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.

Thoughts? cos if you oc too much the driver crashes. |
