I recently upgraded my rigs from XUbuntu 16.04 to XUbuntu 18.04 using Nvidia-driver-470 and t-rex 0.21.5.
On most rigs the hashrate has dropped from 31 to 27 (1070TI).
I have only one rig out of ten that kept the 31 rate...
What could be causing this drop in hashrate
Are they all 1070ti rigs? The 10xx series will drop in hashrate as the ETH Dag size increases. Assuming your mining ETH.
