Pfff the extra power use with v8 is killing me from 710w to 840w and lower hashes. Now i'm ending red numbers 0.19 - $0.22 per kWh.
I hope that srbminer can optimized so we get the old power use back and hashes.
Wow, same here! like 20-25w more per GPU
K, ran some numbers on WhatToMine and its actually more profitable for me to mine CryptoNight V7 on nicehash than it is to mine XMR with CNv8. Man, I was excited for this fork because it would drop the difficulty of XMR (which it did). I was even expecting some level sort of hashing drop, but the extra power usage is crazy...
