Since v1.38 i have experienced a 5% drop in hashrate across all cards on 144/5. I have 3 rigs, 17 1080s and 1 1070. All of the cards are experiencing the same reduction. I am running HiveOS - Latest version - Driver 418.43.
Do the newer versions require less OC or is there a known bug?
It's true, on some cards with limited PL miner may show less hashrate, we will fix it in near update, however without limited PL it will show better hashrate than old version.
