How To Enable NBMiner 70% LHR Mining Performance Unlock On NiceHash


Contents (maximize to view)

Nvidia’s LHR or Lite Hash Rate Graphics Card were launched earlier this year in order to combat cryptocurrency miners who have been hoarding GPUs for mining. LHR variants of the RTX 3060, RTX 3060 Ti, RTX 3070, and RTX 3080 were made to ensure that the GPUs will fall into the hands of gamers.  Additionally, the newly released RTX 3080 Ti and RTX 3070 Ti were also released as LHR cards from the start in an effort to provide more GPUs to gamers. Unfortunately, LHR cards may soon lose their purpose as the latest NBMiner 39.0 version unlocks the mining performance of LHR cards to 70 percent.

How to unlock LHR Mining Performance NBMinerIn the latest GitHub release, NBMiner users can now unlock up to 70% of Nvidia LHR Graphics Cards’ hash rate as opposed to the default 50% mining capacity compared to their non-LHR mining counterparts.  By simpling adding the “-lhr” argument the mining performance of the LHR cards will increase up to a certain amount. According to the patch notes, the user can set a higher value but there’s a higher chance that the LHR GPU will run at its locked state. Note that his method only works in the ethhash/daggerhashimoto algorithm.

We tested the latest NBMiner 39 on our Inno3D RTX 3080 Ti iChill X4 and managed to see an improvement in hash rate. The RTX 3080 ran at 42MH/s and bumped up to 58MH/s after adding the “-lhr 68” launch parameter in NiceHash. The RTX 3080 Ti’s overclocking settings were set at MSI Afterburner running at 70% Power Limit, +0 Core Clock, and +1500 Memory Clock. The test was performed with Nvidia GeForce Driver version 471.41. As of writing, the “-lhr 68” trick won’t work if you are using Nvidia Graphics Driver version 471.11


  1. Download NBMiner 39 on Github

2. Go to the Plugins tab and Find NBMiner. From there click the triple-dot button and click “Show Internals.”  A folder should pop up showing where your current NBMiner app is installed How To use NBMiner 39 on NiceHash3. Open the bins folder then select the higher number and paste the files from the ZIP File you recently downloaded on GitHub.

4. Restart The NiceHash App

6. Benchmark/Start Mining

LHR GPUs LHR Speed NB Miner Update 68% Non LHR Counterpart
RTX 3080 Ti 60MH/s 82MH/s N/A
RTX 3080 49MH/s 66.64MH/s 94MH/s
RTX 3070 Ti 40MH/s 60MH/s N/A
RTX 3070 31MH/s 42.16MH/s 62MH/s
RTX 3060 Ti 30MH/s 40.8MH/s 60MH/s
RTX 3060 20MH/s 27.2MH/s 50MH/s

Here’s a reference table of the increased hash rates for every LHR GPU. Note that your results may vary depending on your GPU model, overclocking settings, and temperatures. In our case, the RTX 3080 Ti should be getting 82MH but our base hash rate was only around 42MH/s which then improved to 62MH/s after the “-lhr 68” update.
