My observations for almost a day of mining on a 12x3080 no LHR rig.
1. If you are using Hive OS, use cuda 11.4, 11.5 gives a slight drop in hashrate.
2. I tried all the cores of the miner, the core does not automatically set correctly in Hive OS (1.42 core 1, 1.43 core 3). You must manually set the sign from 6 to 8 if you use 1.42 and 12-15 if use 1.43 20xx 30xx series of cards.
3. It makes no sense to set the core clock above 1440, it does not give any performance, it only increases the temperature of the cards and power consumption. This only works on older cards like 1070, 1080, 1080 Ti with gdd5 memory. On cards with GDDR 6-6X memory, the core does not participate in ETH mining and there is NO point in increasing it!
I tested the range from 1200 to 1600, anything above 1440 gives a drop in hashrate.
4. Option --xintensity , you need to select individually, for example, it works better for me on 8100 than on 4096.

Bugs that I found, on a rig with 13 video cards 3090x2 3080x7 3070 x4 NO LHR, I could not achieve stable operation, constant dag generation errors and a lot of invalid shares. Also, a 12x3070 NO lhr rig gives errors during dag generation, option --dagintensity 1 is always on.

Wishes, you should conduct detailed tests under HIVE OS, mining on Windows is extremely inconvenient and not popular. Big miners don't use Windows. Improve stability and fix core map definition.

I will continue to test it on different rigs to find bugs and errors in the hive, as well as to find the optimal settings.
