Well I tried automatic functions like undervolt, oc gpu and oc memory but the increased hashrate is from the same manual settings I used before(just used wattman this time instead of overdriventool). Now I just don't need powertable regfile for it. You need to pick one from the automatic options and I just rather do undervolt + oc memory at once so manual works for me better. Also automatic oc never did over 800mhz on memory(it's max value on default settings but with manual one can adjust like before) and I rather have 900mhz at least. There are two memory timing levels but too busy to test them out now(wouldn't know if it could crash and no time for that).

EDIT: Both memory timing levels give a bit better hashrate for me than default value "Automatic". First tier a bit better, very very little. Tried every other gpu miner I know there is and no OS lag(whole windows and videos) with any of them. I hope this is something that can be fixed within teamred so I can go back to it.
