What speed is your 1080ti running? (EThash)

I'm getting 46-47mh currently.

It's a shame nVidia never released a DAG patch like AMD did, If that were the case these would still be at 55mh 

Google Nvidia TLB bug and you'll see why. Nvidia wrote into the hardware of Pascal how it accesses the memory. All Nvidia Pascal GPUs will suffer this issue. Better off selling 1080tis and buying 3060ti's

on my cards I get 46+Mh/s with a consumption of 200W P2 - off but with each epoch the hashes gradually fall ...

6 months later its at 45mh.

Anyone getting much more than 45MH now (April 2021) from a 1080Ti?

This is a known bug in the 10xx series. Only 1070ti was it fixed by Nvidia.

The current hashrate at optimal consumption (about 180-200 watts) is 45-46 megahash. If you increase the power limit, then your hashrate may be higher, but it's not worth the power consumption. Ei video cards can consume 300 watts or more
This is not a bad result for a five-year video card.
