What could be the issue of only ONE rx470 in rig of 8 mining at 11ish mh/s, while the others do stable 27? This was not the case before
experiencing similar symptoms mainly on rx574 18.6.1 drivers (same is on latest one)
It starts normal then from 31,5 falls to 22 mhs
Only thing that helped was dialing down OC on that cards (doesn't work on all my rigs) and running relatively stable on 30.5 mhs (strap 1&2)
Think its related to straps, some are tight and some lose.
