Using NBMiner with memory tweak-6 I reached roughly 76mh/s per card using 2 GTX 1070s.
Without memory tweak, I reached 63 mh/s at 120watts for reference.
settings:
GTX 1070 (1x8 pin,1x6 pin): +700 memory, -300 core, 50% power (around 100w)
GTX 1070 (1x8 pin only): +700 memory, -100 core, 50% power (around 90w)
I’m pretty sure the 10-watt power difference is due to the additional 6pin connector.
90-100w (95w avg) mining on Ergo compared to 140w on Ethereum is insane.
Ran it for a few hours it’s stable so far.
