All GTX 1070 cards after changing the Eth era to 315 began to issue 23 MH instead of 32 MN, another miner gave out 31 MH. What is the reason?
Not sure what you mean. I have a rig with nothing but 1070 Founders Editions (8 of them) and I'm looking at a minimum of 252MH/s. That's an average of 31.5MH/s each.
My clocks are:
Memory: +675
Core +150
Core 925mv
PL 100%
Fan speed 75%
Temp limit 80C
Temperatures range from 63C to 74C
Nvidia drivers 441.66
Windows 10 Pro with 16gb on onboard memory and 56gb of virtual ram.
I am using PhoenixMiner 4.9c though. Not sure if that's making any difference.
