That sounds like sp__ is back!

I would love resolution as then i would just have to switch to your miner without tweaking any cards instead of tweaking 5 rigs with multiple 3070s. Luckily my son has 3070 on this gaming machine so i test here.
I will create a cache of the dag buffer on file. On every new epoc, one of the cards in the rig needs to be able to create the dag buffer. And if the validation fails for the other cards, the program will read from file. Will use around 5GB of harddrive space, but no need to reduce the clocks.
I'm testing 1.45 on HIVE OS. At the start, the hashrate results on the pool and shares are good, I use cuda 11.4 Nvd driv. 470.94 , --kernel 1, --xintensity 1988 , cclock 1311. The miner still gives a dag generation error on rigs 3060 - 3070 . I continue the test.
I noticed that your miner works fine for the first 24 hours, but then the speed slows down, the hashrate on the pool becomes smaller, maybe this is due to Hive OS and cuda 11.4 You should do more tests under HIVE OS, more than 24 hours.
