It's online 0.33b6 GPU
I mined Haven for 48 hours on 3 capricious RX and had a very stable hashrate, varying +/- 2% not more, I hope it will be better for everybody.
My GPUs could get through the warmup, still with swings (mostly RAM frequency, sometimes core freq). Declared speed in itself is highly improved compared to my reference JCE 0.32G version, +15% for same power draw (at wall). If my computer stay stable during the night, I'll check the reported HR at the pool.
