Great job guys this miner is awesome. Easy to use, good hashrates, and zero rejected shares. Here are my results hope this helps someone!
Driver: Adrenalin 19.8.1
Miner: TRM 0.5.7
Afterburner: 4.6.1
GPU: XFX Radeon VII
Test system: 7600K, Asus Z270E, 8GB RAM, EVGA 850 G2, Open Benchtable (open air)
Power consumption numbers are total system power as measured by a Kill A Watt. The system uses about 30w without a GPU so you can deduct 30w from these numbers to get an estimate of the GPU power consumption. I selected what I believe to be my weakest VII so I would expect most cards to do better than this.
Format is:
Voltage/Core Clock/Mem Clock - cn config that the auto tune ended up with, power usage range, GPU temp/junction temp, hash rate range
...
Retested the good settings to verify. Didn't record the cn config since it usually ended up at 13*12 CAB or AAA. Also these tests were done one the same day with the AC on so the temps should be more accurate.
821/1408/1100 - 168w-175w, 50C/60C, 2630-2700
850/1508/1100 - 180w-192w, 52C/63C, 2780-2840
890/1608/1100 - 196w-210w, 54C/66C, 2930-2990
915/1658/1100 - 206w-222w, 56C/69C, 3010-3060
940/1708/1100 - 224w-235w, 57C/72C, 3070-3130
Lower your core and bump your mem clock - CN in general likes faster memory (ideally lower latency, but higher clocks help too) which is usually cheaper power-wise than higher core clocks. I'm running 1550 cclock 1200 mclock 858mv 13*13 AAA, for 2940h/s @ 180w ATW (+/- 3w, including ~19w GPU idle, and prob w/ a bit higher power use due to increased fan speeds from being in an ATX enclosure). I'm still on TRM v0.5.2 for my VII, but I don't believe there have been any significant changes for CNR in later releases. Also, iirc others here have unlocked their mclocks via PPT and dialed up to 1250 to attain even higher h/r and better efficiency.
Btw, there's a separate thread for CN on TRM:
