I have a RX 5700 XT MIS Mech 8gb Windows 10.
It runs fine for 1-12 hours then cuts back to 47mh/s. I have tried adjusting the clock/mem down with a starting hashrate from 57mh/s down to 52mh/s(almost stock). 1230-1340 clock and 1750-1896 mem, all do this reset to 47mh/s...
Any idea why this card would randomly cut back to 47mh/s or a way to diagnose it? A restart of the software does not work I have to reboot the computer. I have 2 RX 570 8gb running with they card at 31mh/s and they are not affected.
Thanks
Put another fan on it cooling it....sounds like thermal throttling.
Use hwinfo to monitor temps particularly the memory junction temps. From what i heard, Mechs are terrible at at cooling memory. Should be below 100c.
