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.

Thanks so much for the response! I noticed that shortly afterwards, it switched to ZCL, and it was then using 105% of the GPU power and KillAWatt moved up. So your explanation makes total sense. I also bumped up the overclock on the Micron RAM in MSI Afterburner on all six cards, and noticed a boost in hashrate. I got greedy at around 330, but got a BSOD, so settled on 250. It has been stable since.

Thanks!
