Today I received a nvidia 2080 ti and I went crazy with what I indicated awesome miner, the miner in question (T-Rex) well marks the hash of mining, but awesome miner in the tab "GPU" misses the data and always indicates that the 2080ti has less speed.
in the rig I have 1 2080ti and a 1080ti.
I realized and I'm more relaxed is awesome miner thing, I thought that tenialgo misconfigured, bios, overclock ... etc
I leave it here too so that it is known.
I have rigti of 1080ti and of rrt 2080 from the same day that came out. There is not a single problem. Well if one, that RTX does not work the change of OC, but lately I do not work on any computer.
I suggest you install Cuda 9.2 and cuda 10 on the RTX team, I do not have a single problem with the RTX, they perform more than the 1080ti and consume less
