If you have GPU's still chugging away at non-ASIC algorithms, you are in luck! Nicehash has released an updated version of their miner 18.104.22.168, which includes software tweaks for additional hashrates.
Our 4GPU test rig was running an average of 798 sols/s on the equihash algorithm with Nicehash Miner 22.214.171.124, and after an easy upgrade to 126.96.36.199, we are now averaging 843 sols/s on the same rig. Not a bad increase for little to no work!
