I am new to mining, so have a newbie question! I have six GTX 1070 GPUs. I allow WinMiner to select the best coin, and it happens to select ETN. With a slight overclock on the RAM, I get a harshate varying from 610-641 h/s, depending upon the card. The GPU utilization is 100%, however the GPU power is only 45%. This is consistent with KillAWatt, which report 300W for a EVGA 750W PSU being used for three cards. My question is why only 45% power? I used some GTX 1080 Ti GPUs the other day, and they were using 100% power.
Ideas? Is this normal, or is something screwed up in my setup?
TIA
ETN uses the Cryptonight algorithm which is bottlenecked by memory access latency, not by compute speed. Your GPU's compute units are fully utilized technically speaking, but they spend a lot of their time not actually computing but rather waiting for data to be fetched from RAM, so they use far less power than with different algorithms that don't really have the same bottleneck and spend more time actually crunching numbers.
