I'm getting great results with this miner. Many thanks for your work, dstm.
No crashing here.

v0.5.3 was closing itself(?) occasionally, I assume it was losing connection to the pool and running out of reconnect attempts.
I'm testing 0.5.5 now to see if the problem still exists without the reconnect attempt limit.
Should really use the log I suppose.

GTX 1070
420sol/s @ 4.0 sols/w
Afterburner 800mV, +188mhz core, -50 mem

GTX 1080
515sol/s @ 4.2 sols/w
Afterburner 800mV, +125mhz core, -50 mem

try add memory, not minus -50? make +300 instead
you will see you will get more sol/s
cause equihash algo loves memory speed

Thanks for the suggestion.
I agree, but I found that increased memory speed only starts to make a significant difference when used with higher core frequencies (say, 1850+ ish).
I was aiming for good efficiency which meant keeping core freq relatively low - usually ending up somewhere around 1670-1800MHz (at 800mV) depending on the quality of the chip.
Pascal seems to be very efficient at this voltage and capable of a significant overclock which is ofc desirable.
So, at these core frequencies, the reduced memory freq further reduced the total power consumption without significantly hindering the hash rate.

All of this said, it makes almost no difference anyway. You can vary a cards power consumption (reported) by up to about 4-5W though memory clock speed adjustments in my experience.

Interestingly, ZM uses less power than EWBF -and- gets a higher hash rate at the same time. It made my sols/w epeen shoot friggen rainbows.
