Hello,
I bought a used MSI RTX 3080 Ventus 3x 10G OC "non-LHR" for Ethereum mining and wanted to know if it is necessary to update the BIOS to get better hashrates. What do you think?
First, check the hashrate in Ethereum mining. If your hashrate is around 90 megahash, then you don't need to do anything. If your video card turns out to be an LHR version, then choose a miner with the maximum hashrate. Although this is offset by increased power consumption and overheating.
