NBMiner squeezes 70 percent ETH performance out of NVIDIA GeForce RTX 30 LHR cards

There is a new version of the NBMiner software that is able to circumvent some of the anti-cryptocurrency mining restrictions on NVIDIA's GeForce RTX 30 LHR video cards. The latter updated its gaming video cards earlier this year to make them less attractive to miners. Via a combination of a firmware and driver update, NVIDIA basically halved the mining performance of new retail cards.

NBMiner claims to restore 70% of mining performance

It took a couple of months but the developers of the NBMiner software managed to figure out a new software-based approach to unlock some of the lost mining performance. VideoCardz writes version 39.0 of the NBMiner crypto GPU miner can unlock about 70 percent of the maximum unlocked hashrate on the RTX 3080, 3070, 3060 Ti, and 3060 "Lite Hash Rate" GPUs.
The NBMiner update does not unlock the mining performance of LHR chips. Instead, it offers an adjustable value that determines the maximum unlockable hash rate for a specific GPU. The developer suggests using 68%, which means that the GPU will offer not 50% by 68% of Ethereum mining using ethash algorithm exclusively (no other algorithm is currently supported). -- VideoCardz

It works

WCCF Tech reports the performance unlocking works as advertised. Miners can expect around the following performance:
  • NVIDIA RTX 3080 Ti (LHR) - ~80 MH/s (RTX 3080 Non-LHR - ~90 MH/s)
  • NVIDIA RTX 3070 Ti (LHR) - ~50 MH/s (RTX 3070 Non-LHR - ~60 MH/s)
  • NVIDIA RTX 3060 Ti (LHR) - ~40 MH/s (RTX 3060 Non-LHR - ~50 MH/s)
