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.
There are some miners with no clock settings built in, so you will need a third party software.
IMO Afterburner is for amauters or testing stability before going live because in case of power loss your cards can reset the clocks to default, setting on the miner cfg or either on BIOS your cards will never miss clocks settings. You can set a script as well.
