Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

I compiled Ethminer https://github.com/ethereum-mining/ethminer/blob/master/docs/BUILD.md and it works. But I did have to change ethminer/libethash-cuda/CMakeLists.txt to ignore old (sm_30-35 that don't work with CUDA 11) and add new 86 architecture (list(APPEND CUDA_NVCC_FLAGS "-gencode arch=compute_86,code=sm_86")).

What hashrate does Ethminer give you for the 3080?

86.5. For 2080 Ti with +300 mem OC it's 52.7.

Was 86.5 mh the fastest you could get with Ethminer?

I didn't do any additional OC outside of what manufacturer did yet. Only power limiting. I'd guess it can do a bit more. Especially since 3090 mem has a lil bit higher frequency and it's based on same memory modules from what I know.

Others were getting around ~100 mh at around ~250watts for the 3080 when overclocked, but these were on various non-open source miners. It'll be interesting to see what Ethminer can do with the 3080 overclocked.
