Is there any gain by over locking in the config file instead of using something like afterburner?
I use afterburner and it works pretty damn good. Just wondering if there is some sort of performance gain to do it in the config for the miner instead.
Performance don't think so. I think clocks may be more set in stone on some cards with config though. Also if you switch coins easier to set different for each one. Also easier to change en masse with config, or through remote manager. If tuning each card, using config make it easier to adjust for instability since numbers in log same as order you set them... Down to preference really.
