Best GeForce RTX 3080 Ti LHR Overclock Settings for Mining Ethereum

5 Mins read

The GeForce RTX 3080 Ti is a beast of a graphics card. It features a mind-blowing 10,240 CUDA cores, as well as 320 Tensor cores and 80 RT cores, which allow it to smoothly run even the most demanding games at 4K resolution at 60 FPS. Performance-wise, the RTX 3080 Ti is only around 1% slower than the GeForce RTX 3090, and around 11% faster than the non-Ti GeForce RTX 3080. Featuring such great specifications and performance, one can only wonder whether this card is also good for mining? Well, the answer is simple: Yes it is!

Compared the GeForce RTX 3080 and the RTX 3090, which were both released in 2020 and had no built-in cryptocurrency limiters, all the RTX 3080 Ti cards come with an infamous LHR mining limiter which significantly decreases its mining performance. This means that the GeForce RTX 3080 Ti is only able to deliver around 57 MH/s at stock speed while mining Ethereum, while the “unlocked” RTX 3090 can deliver around 120 MH/s, which is almost two times better performance. The built-in mining limiter also seems to affect the card’s performance while mining altcoins, such as Ergo (ERG). However, some cryptocurrencies that don’t seem to be affected by the built-in limiter, such as Conflux (CFX) or RavenCoin (RVN).

As of May 7th 2022 all LHR cards can now be fully unlocked! If you plan to mine Ethereum with the RTX 3080 Ti LHR we strongly recommend using the latest version of NBMiner or NiceHash QuickMiner. These miners fully bypass the card’s built-in mining limiter, thus allowing the card to achieve its maximum mining speed.

Although the RTX 3080 Ti features a graphics chip with certain hardware modifications that limit its mining performance, as of May 2022, the card’s mining potential can be fully unlocked, since new miners featuring 100% LHR unlocks have appeared. For many owners of the RTX 3080 Ti, this news should bring a lot of relief, as the updated miners now allow their card to mine at a much higher hashrate. This means that with proper overclock settings and the right software, you can now increase the RTX 3080 Ti’s base Ethereum mining hashrate from 57 MH/s up to 122 MH/s, which is a performance increase of a whooping 72%. Continue reading to find out more how to unlock your RTX 3080 Ti’s mining performance.

Best Overclock Settings for Mining Ethereum with GeForce RTX 3080 Ti

Before you start mining Ethereum with the GeForce RTX 3080 Ti LHR, we recommend overclocking the graphics card in to order maximally improve its performance. However, it must be noted that you should use overclocking at your own risk! ViCadia.com does not take any responsibilities related to overclocking or performing any adjustments to your computer. You have been warned!

First of all, download the latest versions of the MSI Afterburner and HWiNFO64 (if you use Windows PC). Use MSI Afterburner to manually set core clock, memory clock and power limit values for your graphics card. We strongly recommend using the HWiNFO64 tool to closely monitor core clock and VRAM temperatures. If you notice any unusual behavior with your graphics card, immediately revert to default settings.

For purposes of this guide we’ve used MSI Gaming GeForce RTX 3080 Ti VENTUS 3X OC graphics card. Down below you can find overclock setting which worked best for us. These OC settings may not necessarily work for your card. Each AIB variant of the RTX 3080 Ti performs slightly different.

For purposes of this guide we’ve used MSI’s GeForce RTX 3080 Ti VENTUS 3X OC gaming graphics card

Here are the overclock settings that worked best for our card:

  • Lock the GPU core clock to 1,100 MHz (you can use MSI Afterburner’s Curve Editor to do that)
  • Increase Memory Clock offset to +1,500 MHz, or set to 2,800 MHz (if you use HiveOS)
  • Set Power Limit to 100%
  • Set Fan Speed to Auto

Ethereum Mining Performance & Benchmarks

In order to examine our card’s mining performance, we’ve used four different miners: NBminer 41.0, GMiner 2.74, T-Rex 0.25.13, and lolMiner 1.38. The reason why we used some older versions of the mentioned miners is the fact that they consume a lot less power, and as such are able to deliver very good and competitive mining efficiency. All tests were performed with applied overclock settings, and on PC running Windows 10 with installed NVIDIA’s 512.59 graphics drivers. Down below you can see our benchmark results.

RTX 3080 Ti LHR (OC)Hashrate (avg.)GPU Temp (avg.)Fan Speed (avg.)Total Power DrawEff./Watt
NBMiner 41.0

122.4 MH/s47°C100%289 W423.5 kH/J

lolMiner 1.38
(LHR 25.8)
82.9 MH/s42°C80%264 W314.0 kH/J

As you can see, the NBMiner 41.0 is currently the best miner to use with the GeForce RTX 3080 Ti, as it’s able to fully unleash the card’s true mining potential. With our custom overclock settings, the NBMiner was able to push our RTX 3080 Ti to deliver an unbelievable 122.4 MH/s hashrate, which was simply an incredible result. Second place took the T-Rex miner 0.25.13, which could deliver pretty good 95.5 MH/s, but this was nowhere near the result that NBMiner could deliver.

Despite the fact that GMiner features a pretty low developer’s fee of only 0.05%, its mining performance with the RTX 3080 Ti lags far behind the NBMiner, so we don’t see any point using it until its developers introduce their own 100% LHR unlock. The same could be said about lolMiner as well. Down below you can see a chart showing the performance and efficiency difference between all four tested Ethereum miners.

There is no doubt that the NBMiner is currently the best miner to use with the GeForce RTX 3080 Ti, especially if you want to mine Ethereum. The NiceHash QuickMiner is also a pretty good miner, however, we didn’t include its benchmark results in our guide, since we constantly experienced stability issues while running it with our MSI RTX 3080 Ti VENTUS 3X OC.

Despite the fact that miners without 100% LHR unlocks are now pretty much obsolete, they can be useful in some very specific scenarios. If you take a look at our data table above, you can clearly see that both GMiner and lolMiner consume around 25 W less than NBMiner. Despite that, their power efficiency still pales in comparison to what NBMiner can deliver (423.5 kH per watt), but if you live in an area where electricity is expensive, and you want to optimize your mining costs, using an older miner without 100% LHR unlock may still seem like a viable option.

With this level of performance that the NBMiner can offer, the RTX 3080 Ti can finally deliver the same mining hashrate as the mighty GeForce RTX 3090, but for much less money and power. This makes the GeForce RTX 3080 Ti an extremely good and profitable graphics card for mining, provided that Ethereum’s price remains high.

Final words

What can we say, other than the fact that we’re extremely thrilled to see LHR cards finally being unlocked and our GeForce RTX 3080 Ti rocking 122 MH/s. These are great news for all crypto entrepreneurs, however, we do think that all this comes a bit too late. Ethereum is becoming very difficult to mine, and prices of electricity are soaring up due to ongoing geopolitical circumstances, so unlocking LHR cards may not be enough to make mining as profitable as it used to be.

Nevertheless, we are very happy to see miners finally extracting full potential out of their LHR cards. We hope you liked our guide and found information here to be useful. We’ll continue updating this guide with new benchmarks, and we hope seeing other miners offering 100% LHR unlocks soon. If you have anything to share with us, feel free to post a comment below.
