Hy, my Vega'64 (Samsung) config for CNR and TeamRed miner. Draws more power but adds 1.8Khs.

your temps are high and hw errors in teamred miner is a bad sign
Bump your fans a bit more and you should be able to get your temps down a bit. I have been runing my vegas at 60C for nearlly 18months and they are still sweet as.
Try lowering WR a little and see if that gives a bit more.
