Thanks to its 3584 CUDA cores, and 12GB of VRAM, the GeForce RTX 3060 is a graphics card that has the potential to bring next-gen raster and ray-tracing performance to masses. But besides being suitable for high FPS gaming at 1080 or 1440p resolution, this card is also well-suited for mining cryptocurrencies, such as Ethereum (ETH) or other altcoins like Ravencoin (RVN) and ERGO (ERG).

Unfortunately, most GeForce RTX 3060 graphics cards come with a built-in crypto mining limiter which nerfs the card’s performance while mining Ethereum. However, the built-in limiter only affects Ethereum mining performance, which means you can mine other cryptocurrency coins without any issues.

Update 8 Oct 2021: We’ve added benchmarks for T-Rex 0.24.0 miner which introduced “dual mining mode” LHR unlock. We strongly recommend using the latest version of NBMiner or T-Rex miner if you plan to mine Ethereum with the RTX 3060 LHR. These miners partially bypass the card’s built-in mining limiter, thus allowing the card to deliver up to 47% better mining hashrate.

If you own a first generation RTX 3060 card that has a GA106-300 chip, then you can easily bypass the built-in limiter by simply installing the 470.05 driver which unlocks the card for mining Ethereum. This will allow you to mine Ethereum at hashrate of 40-50 MH/s. If, however, you own a second generation RTX 3060 (LHR) that has a GA106-302 chip, then you’ll have to settle with a 21-23 MH/s mining performance, but with a few tweaks, and proper mining software, you may be able to push your card up to 34 MH/s mining hashrate. To find out how to squeeze some extra performance out of your GeForce RTX 3060 card, keep reading further.

Best Overclock Settings for Mining Ethereum with GeForce RTX 3060

Before you attempt to mine Ethereum with you GeForce RTX 3060, we strongly recommend overclocking the card in order to achieve the highest possible hashrate, and lower the card’s power consumption as much as possible. The settings we are about to show you can be applied both to the standard RTX 3060 cards, as well as to the RTX 3060 LHR cards.

Of course, use overclocking at your own risk! This will void the warranty of your graphics card, and may even destroy it, or damage its components. ViCadia.com does not take any responsibilities related to overclocking or performing any adjustments to your computer. You have been warned!

To overclock you GeForce RTX 3060, first download and install the latest version of the MSI Afterburner software. You can download it from here. Once you do that, open the program’s interface, and apply these settings:

Recommended overclock settings for NBMiner, GMiner, and T-Rex miner (in single mode):

  • Decrease Core Clock value to -502 MHz
  • Increase Memory Clock value to +1284 MHz
  • Lower Power Limit to 65%
  • Leave Fan Speed at default settings

Recommended overclock settings for NBMiner 0.24.0 (in dual mining ETH+ERGO mode):

  • Reset to default settings in MSI Afterburner (if you already have any applied overclock settings)
  • Open the “LHR-unlock-dual-ETH+ERGO” batch file in T-Rex 0.24.0 folder, and add necessary code to run T-Rex miner with administrative privileges. For more information please read this post on Reddit, or watch this video by Sebs FinTech Channel instead.
  • Inside the batch file, before the “pause” text, add this code:
--lock-cclock 1250 --mclock 1300

If you followed our instructions correctly, your settings in MSI Afterbuner should look something like this:

Ethereum Mining Performance & Benchmarks

For purposes of this overclocking guide, we’ve used our EVGA GeForce RTX 3060 XC Gaming graphics card. In order to examine the card’s Ethereum mining performance, we’ve used five different miners: NBMiner v39.5, PhoenixMiner v5.7d, GMiner v2.69, T-Rex v0.24.0, and NiceHash QuickMiner v0.5.1.3. We’ve benchmarked the card’s mining performance only while running on overclocked settings, since with stock settings the card mines very inefficiently. Fan speed, GPU core temperature, and total board power draw were recorded with GPU-Z v2.41.0. Here you can see our benchmark results:

RTX 3060 LHR (OC)Hashrate (avg.)GPU Temp (avg.)Fan Speed (avg.)Board Power DrawEff./Watt
NBMiner 39.533.0 MH/s59°C65%94 W351.0 kH/J
GMiner 2.6932.8 MH/s59°C65%97 W338.1 kH/J
T-Rex 0.24.034.0 MH/s61°C67%110 W309.1 kH/J
T-Rex 0.24.0
(ETH+ERGO)
13.3 MH/s (ETH)
73.0 MH/s (ERGO)
55°C63%85 W157 kH/J (ETH)
859 kH/J (ERGO)
PhoenixMiner v5.7b26.3 MH/s61°C67%110 W239.2 kH/J
NiceHash QuickMiner24.0 MH/s59°C57%81 W296.3 kH/J

We’ve also plotted a chart that more clearly depicts the performance difference between different Ethereum miners.

As you can see, the NBMiner v39.5 is a clear winner here, at least when it comes to pure Ethereum mining efficiency. The T-Rex 0.24.0 (single mode) miner is able to deliver slightly better hashrate of 34.0 MH/s, but at the expense of higher power consumption. Overall, both miners are able to deliver roughly 25% better performance compared to the PhoenixMiner v5.7b which, unfortunately, still doesn’t feature any LHR unlocks. The GMiner was also able to deliver very good hashrate, however, the card’s mining performance wasn’t as consistent as it was with NBMiner or T-Rex miner. It must be noted that we used LHR 68 mode while mining with NBMiner, because with default LHR 69 mode our card experienced frequent mining lockups. For T-Rex miner we’ve used –lhr-tune 4 parameter to achieve stable and partially unlocked mining hashrate.

T-Rex 0.24.0 miner running in dual mining mode

With version 0.24.0, the T-Rex miner also introduced dual or hybrid mining mode, which unlocks the ability to simultaneously mine both Ethereum and Ergo (or Conflux and RavenCoin). For purposes of this guide, we’ve only tested mining performance while mining ETH and Ergo. As you can see from our screenshot above, this “hack” works pretty well, however, mining performance is a bit underwhelming. The miner has to run with custom overclock settings in order to avoid triggering the LHR limiter, but this in turn limits the ETH mining hashrate to around 13 MH/s, and Ergo mining hashrate to 73 MH/s. Good thing, however, is that total board power draw is only around 85 watts, which increases RTX 3060’s mining efficiency to 1,015 kH/J (when adjusted). Overall, the dual mining mode concept seems pretty interesting, and if you don’t mind somewhat low hashrate, and want to simultaneously mine two different coins with your card, running T-Rex miner in dual mining mode may prove very useful.

It is also worth saying a few things about NiceHash QuickMiner’s mining performance. As you can see from our tables, the mining performance with this miner was pretty underwhelming, however, it was also the least power consuming. The QuickMiner applies its own overclock settings and overrides the settings we applied using the MSI Afterburner. The major advantage of NiceHash QuickMiner over other miners while mining Ethereum with the RTX 3060 is the fact that it significantly reduces the power consumption of the card, and keeps the card running below 60°C. This in turn makes the QuickMiner one of the most efficient miners to use with the GeForce RTX 3060, so if you want to prevent the wear and tear of the card, this is the best miner to go with.

Of course, if raw performance is all that matters to you, and you want to mine Ethereum as quickly and as efficiently as possible, then applying our OC settings and using the T-Rex miner is the way to achieve success.

We hope you found our GeForce RTX 3060 mining guide helpful. With these tips and tricks, you can turn your GeForce RTX 3060 LHR into a serious mining graphics card. Hopefully, the developers of NBMiner, GMiner and T-Rex miner will improve even more their software’s mining performance on LHR cards, which in turn will make those cards even more profitable.
