I was having two issues:
- Random reboots
- Miner shows its working, but Ethpool showing average hash rate decline
I "think" I have found the issue. One of my GPU's runs ~5 degrees hotter than the others and once it gets to 72 degrees it slows down or crashes causing claymore miner to crash/fail or a system reboot. I ran the GPU with the other 5 GPU's powered off and the heat issue remained probably due to a defect in the card. My fix is to increase the fan speed from auto, which was running ~40% fan speed and hard coded the fan speed to 80%. Why 80%? I researched and found that to be a common setting for the GTX 1070 and not wanting to take the time to experiment, I just went with it.
My [CURRENT] MSI Afterburner settings
- Core Voltage: <Default>
- Power Limit: <Default>
- Temp. Limit: <Default>
- Core Clock: -120
- Memory Clock: +600
- Fan Speed: 80%
I am getting around ~181MH/s consistently with Claymore dual-miner 9.6 on Windows 10. My GPU's are consistenty below 60 degrees including my problem-child GPU.
I still can't get 9.7 to run overclocked past 175MH/s with my current setup.
