RTX 3080 Ti Gains 91+ MH/s Ethereum Hashrate Record Performance Using Nvidia LHR Unlock Mode Through Latest NBMiner v40,1

Jensen Huang is swimming in his money that cumulated from Ethereum crypto mining trend. Latest developments on unlocking Nvidia’s LHR hashrate limiter for RTX 3000 GPUs have been never better. As usual, NBMiner is still squeezing extra hashrate juice out of RTX 3080 Ti with latest v40.1 release.

Unbelievable 91+ MH/s record breaking RTX 3080 Ti GPU hashrate was achieved by tech enthusiast Mike Biddle who also put new detailed NBMiner settings in one blog post. Interestingly, Mike uses special lines of coding to manipulate LHR unlock mode effectively. Rarely, MSI Afterburner is used to monitor some card settings.

Obviously, latest NBMiner likes absolute core and memory clock settings within bat executable document rather than MSI Afterburner undervolted or overclocking tuning which is sometimes unstable for mining. So the secret sauce to obtain 91 MH/s from RTX 3080 Ti is concluded at setting absolute clock speeds, right timing for LHR and LRV stepping. In actual implementation Mike Biddle has put for two GPU settings exactly like this:

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
