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.

True. Got to 100 with OC. Mem running at amazing 21200 MHz. Fantastic card. My 2080 ti maxed out at something like 58.
