Afterburner is good OC software for gpu, just one adjustment for all gpu. But i have been stop using it, because I think every gpu has its own characteristics although 1 type. I once used it and i checked in hwinfo 2-3 gpu occurred "GPU memory error". So now i prefer to use overdriveNtool to setting OC my gpu, although adjusting per gpu but it worth . And I think hashrate is more stable.
