In its 3000 series of video cards, Nvidia began releasing video cards with the prefix LHR, which in mining Ethereum cryptocurrency began to show twice lower hash rate than similar video cards, but without this blocking. Since Ethereum cryptocurrency is the most popular GPU mining cryptocurrency and at the same time the most profitable for mining, so all developers of specialized mining software began to look for ways to circumvent these artificial restrictions. As of April 2022, the best results in unlocking LHR were achieved by the developers of Lolminer miner. Starting with version 1.47 Lolminer managed to unlock up to 78% of the capabilities of such video cards.
Recall that all RTX 3050, RTX 3060, RTX 3060Ti, RTX 3070, RTX3070Ti, RTX 3080, RTX 3080Ti graphics cards have LHR mining limiter. At the same time, models released before May 2021 RTX3060, RTX 3070 and RTX 3080 initially have no LHR and therefore are now in high demand among cryptocurrency miners. The older RTX 3090 and RTX 3090Ti models did not get such a limiter in mining. Ways to determine whether LHR video card is yours or not are described in this article.
According to the developers they were able to unlock video cards with GDDR6 memory up to 78.2% LHR (RTX3060 LHRv2, RTX 3070) and video cards with GDDR6X memory up to 77% LHR (RTX 3070Ti, RTX3080LHR, RTX 3080Ti). For the latest graphics cards released in 2022, RTX 3050 and RTX 3080 12Gb unlock percentage is only 58%, not much more than the original 50%.
The exception in this list is the RTX 3060 LHRv1, which managed to unlock 86% when using 460.39 drivers.
For other LHR models you need to use 470.103.01 or all 501.x.x drivers to unlock
Next we will test RTX 3050 LHR, RTX 3060 LHRv2, RTX3060Ti, RTX 3070, RTX 3070Ti and compare with the claims of lolminer developers.
| Graphics Cards | Hash rate EThash | GPU | Memory | TDP |
| RTX 3060 LHRv2 | 38.4Mh/s | 1575Mhz | 2500Mhz | 110W |
| RTX 3060 Ti | 46.6Mh/s | 1380Mhz | 2050Mhz | 132W |
| RTX 3070 LHR | 48.5Mh/s | 1065Mhz | 2700Mhz | 109W |
| RTX 3070 Ti | 62.5Mh/s | 975Mhz | 3000Mhz | 180W |
| RTX 3080 LHR | 77.5Mh/s | 1380Mhz | 3100Mhz | 234W |
| RTX 3080 Ti | 94.5Mh/s | 1440Mhz | 3100Mhz | 255W |
The tests were done in HiveOS with Nvidia driver 470.103.01
Conclusion: lolminer developers really managed to make the most profitable miner for Nvidia RTX video cards with LHR blocker. In some cases, the percentage of unlocking is even higher than it was announced, but it's rather the merit of tested video cards and their ability to overclock memory and GPU. If you have Nvidia video card with LHR, we recommend you to use Lolminer version 1.47 or newer, but keep in mind that in your case the commission for minifying Ethereum will be 1%, not 0.7% for video cards without LHR.
