Last Updated on January 8, 2022 by ViCadia

In May 2021, NVIDIA launched the new GeForce RTX 3070 Ti graphics card, thus continuing the rollout of GPUs based on its Ampere microarchitecture. Compared to the “non-Ti” GeForce RTX 3070, the new card features slightly higher base and boost clocks, 256 more shading units, 8 more TMUs and Tensor cores, as well as 2 more RT cores. Interestingly enough, the card features the same number of transistors (17.4 million), but is able to deliver 6.8% higher FP32 compute performance (21.75 TFLOPS). Despite its great specs, its mining performance falls short of expectations, and in this article we’ll discuss this in greater detail.

Compared to the standard GeForce RTX 3070, the GeForce RTX 3070 Ti features a built-in cryptocurrency mining limiter, meaning its mining performance is somewhat impaired. This means that all RTX 3070 Ti cards available on the market come with the built-in “LHR” (lite hash rate) technology, and unlike the GeForce RTX 3060 Ti, there are no variants of the RTX 3070 Ti that feature a fully unlocked mining potential. The built-in mining limiter makes the RTX 3070 Ti much less profitable then some other cards, however, with certain tweaks and workarounds, it is possible for this card to deliver favorable mining performance.

Notice: We strongly recommend using the latest version of T-Rex miner or GMiner if you plan to mine Ethereum with the RTX 3070 Ti. These miners partially bypass the card’s built-in mining limiter, thus allowing the card to deliver up to 24% higher mining hashrate.

Without any overclocks and tweaking, the stock GeForce RTX 3070 Ti is able to deliver 46 MH/s hashrate while mining Ethereum, which is roughly on par with the fully unlocked GeForce RTX 3060. Overall, this is quite disappointing performance, since the RTX 3070 Ti comes with a 58% higher MSRP than the GeForce RTX 3060, and features a 52% higher TDP, meaning its price-to-performance ratio pales in comparison to the RTX 3060.

Fortunately enough, with a few tweaks and proper software, the GeForce RTX 3070 Ti can be turned into a fairly profitable mining graphics card. In past six months, there have appeared numerous cryptocurrency miners that feature software unlocks which partially unlock mining performance on NVIDIA’s LHR cards. Miners such as NBMiner, GMiner, and T-Rex miner now allow you to improve your card’s mining hashrate, as well as lower its power consumption to improve its efficiency. This means that the RTX 3070 Ti’s base Ethereum mining hashrate can now be increased from the initial 46 MH/s to up to 59 MH/s. In this guide we’ll show you the best overclock settings for mining with the RTX 3070 Ti, and examine which miner performs the best with this card.

Best OC Settings for Mining ETH with GeForce RTX 3070 Ti

Before you start mining Ethereum or any other crypto with the GeForce RTX 3070 Ti, we recommend overclocking the card in order to improve its mining performance as much as possible. 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!

Before you begin mining with your RTX 3070 Ti, first download the latest version of the MSI Afterburner and HWiNFO64. Use MSI Afterburner to manually adjust core clock, memory clock, and power limit parameters for your GPU. For keeping a close eye on core clock and VRAM temperatures, we recommend using the HWiNFO64 tool. If you notice any strange behavior from your GPU, reset to the original settings immediately!

For purposes of this guide we’ve used the ZOTAC Gaming GeForce RTX 3070 Ti AMP Holo OC. Down below you can find overclock settings which worked best for our card. These OC settings may not necessarily work for your card! Each AIB model of the RTX 3070 Ti may perform slightly differently.

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

Use these settings if you plan to mine with NBMiner, GMiner or T-Rex miner:

  • Lock the GPU core clock to 930 MHz (use NVIDIA SMI or edit miner config file), and increase core clock to +100 MHz using the MSI Afterburner (in order to lower the card’s voltage)
  • Increase Memory Clock value to +1150 MHz (via MSI Afterburner)
  • Set Power Limit to 100%
  • Set Fan Speed to Auto (you can also decrease it, but don’t go below 85% because the system will crash)

Use these settings if you plan to mine with lolMiner on HiveOS:

  • Lock the GPU core clock to 930 MHz
  • Set the memory clock to 2300 MHz

Ethereum Mining Performance & Benchmarks

In order to examine our card’s mining performance, we’ve tested four different miners: NBminer 39.7, GMiner 2.71, lolMiner 1.37, and T-Rex 0.24.6. All benchmark tests were performed with applied overclock settings, and on PC running either HiveOS or Windows 10 with the latest NVIDIA’s 497.09 graphics drivers. Fan speed, GPU core temperature, VRAM temperature, and total board power draw were recorded via HWiNFO64 v7.14. Down below you can see our benchmark results.

RTX 3060 Ti LHR (OC)Hashrate (avg.)GPU Temp (avg.)Fan Speed (avg.)Total Power DrawEff./Watt
NBMiner 39.7
(LHR 75)
58.10 MH/s49°C85%181 W321.0 kH/J
GMiner 2.71
(LHR 73)

T-Rex 0.24.6

lolMiner 1.37
(LHR 9.8)
56.20 MH/s48°C80%183 W307.10 kH/J

As you can see from the table above, practically all miners perform roughly the same, with the exception of lolMiner 1.37 which appears to be underperforming both in mining speed and efficiency. When it comes to raw mining speed, the T-Rex miner is a clear winner here, since it’s able to deliver 59.3 MH/s hashrate for a total power consumption of 187 W. There is no doubt that the T-Rex miner is the most power-hungry miner among all four tested miners, but its mining efficiency is quite competitive, thanks to its above average mining speed.

Both GMiner and NBMiner were able to deliver the same mining hashrate, except that GMiner proved to be a much more energy efficient option, since it consumed 7 W of power less than the NBMiner. With GMiner, our tested RTX 3070 Ti card also ran the coolest and quietest, with GPU core temperature averaging at around 49°C, and fans being stuck at 78% rotational speed. Down below you can see a performance efficiency chart that provides a much better insight in performance differences between tested miners.

As you can see, the GMiner is the most energy efficient miner among all four tested miners. The GMiner is able to deliver roughly 334 kH per watt, which is quite good performance. With this miner, the RTX 3070 Ti is able to outperform even the GeForce RTX 3080 Ti LHR when it comes to mining efficiency. But besides offering good mining performance, the GMiner also features the lowest developer’s fee of only 0.65%, meaning that with this miner you may be able to earn more compared to using other miners. Of course, if raw mining hashrate is all that you care for, then the T-Rex miner seems like a better choice to go with (especially if you own the RTX 3070 Ti).

Overall, all miners were able to significantly improve our RTX 3070 Ti’s mining performance, but these results still fall short from expectations, given the fact that the RTX 3070 Ti costs roughly the same (if not even more) as the AMD Radeon RX 6900 XT, which can boast with higher mining hashrate (64 MH/s) and lower power consumption (150 W).

With mods, the GeForce RTX 3070 Ti can have up to 16GB of VRAM. Image credit: VIK-on

Right now, the GeForce RTX 3070 Ti doesn’t seem like a worthwhile investment if you are looking for a graphics card to mine Ethereum or other crypto coins. Sure, the card is able to provide fantastic 1440p and 4K gaming experience, but when it comes to mining, it falls short of expectations. Efficiency-wise, it may seem more profitable than the RTX 3080 Ti LHR, but given the fact that there are much faster, cheaper and more efficient mining cards out there, recommending anyone to buy the RTX 3070 Ti exclusively for mining is quite difficult.

However, we hope that developers of cryptocurrency miners will find ways to fully unlock this card’s mining potential, and make it much more profitable than it is now. We hope you liked our guide, and that you found the information we’ve provided here to be useful. If you have any thoughts you want to share with us, feel free to post a comment below. Stay safe & happy mining!
