GPUs (graphics At the end of November 11 thousand of people were mining cryptocurrency in the 2Miners pool, whereas now there are over 44 thousand. MH/s, 45.0 To mine efficiently in 2021, you need a GPU with at least 5GB of RAM. However, note that the power draw we're reporting doesn't include PSU inefficiencies or power for the rest of the PC. Meanwhile, just overclocking the VRAM improved performance by 2.1% in BL3 and 6.0% in CP77. Nvidia includes the fan power consumption into PL, so the core may start lacking power. Overview of the worker with two AMD GPUs In this case first you need to restore the operating mode after reloading, and only then activate mining. The odd bit is that the 2080 Super requires substantially higher memory clocks to get there. Let's take each card in turn. Bring the memory clock to a minimum. There are a variety of utilities, but we're going to focus on MSI Afterburner, which is one of the most popular and commonly used GPU overclocking tools. GeForce RTX 3080 Founders Edition: Tuning this card was very similar to the 3090 FE. With that initial performance boost in play, we then tried a 150 MHz core overclock and Cyberpunk 2077 almost immediately crashed. Launch the MSI Afterburner; Locate the memory clock slider and start to increase the value progressively. Overclocking needs special software downloading This program works on all GPUs regardless of the brand and allows you to modify all settings, like If you can keep your GPU and other components cool, they'll last longer and not break down as often. MH/s, 105.0 That's not an error. If you are also thinking about cryptocurrency mining and you are planning to use Nvidia graphics cards, this article is for you. GeForce RTX 3070 Founders Edition: The main thing for improving performance on the 3070 was to boost the GDDR6 clock. Optimal efficiency can vary a bit, but for the GA104-based cards, GDDR6 speed is the limiting factor on performance. Maximum memory clocks are still critical, but core clocks start to matter morethe architecture isn't tuned for compute as much as Turing and Ampere. Make sure that the memory clock is now above 7000 MHz. But perhaps even worse than that is the fact that overclocking usually only improves performance by 510%. Not only will the fans make a lot of noise, but they're also destined to fail sooner rather than later. Find the clock value that makes the GPU driver crash (reload), and move 50 MHz down to the stable area. The OC scanner can take 20 minutes to run, and most of the time, you can get a quick and easy overclock much faster on your own. Tuning your card for the best performance and efficiency is important. You might do fine, you might do great, or you might end up with a lot of extra PC hardware and debt. That ticks all the boxes for a demanding game that will likely push the GPU to its limits, and it also has a built-in benchmark that will let us see what happens to performance after tuning. If you want to know how to mine Ethereum, we cover that elsewhere, but the "how" is quite different from the "why." Its mainly due to the enhanced memory access algorithm. Example. At stock, the fans end up running at 100% to try to keep the GDDR6X below 110C, and that's not good. Let's talk about the big picture quickly before we get into the details. MH/s, 25.62 First, let's note that we're not trying to actively encourage anyone to start a mining farm with GPUs. The 3070 is easy to overclock. That reduces power use and temperatures and boosts overall efficiency. It has a user-friendly interface and works with any Nvidia or AMD GPU. Download CPU overclocking software. Tom's Hardware is part of Future US Inc, an international media group and leading digital publisher. Still, the results we've shown above aren't atypical for graphics card overclocking, and we usually see about a 510% improvement in performance. MH/s, 35.04 About 40W of power goes to the CPU, motherboard, and other components, while the remainder depends on how much power the GPU uses, including PSU inefficiencies. You can try bringing the core and memory voltage to 740. Just remember to account for power costs and cash out enough coins to cover that, and then hopefully you won't get caught holding the bag. We're going to skip all the baseline performance metrics this time, and just jump straight to optimized performance. On the 3080, the FE ended up just 2% slower while using 6% more power. We will update it as we get the new data. After tuning, the RX 6600 XT basically gets about 2/3 the hashrate of the RX 6700 XT. But there's more to it than just firing up the software and letting it run in the background, especially if you've managed to procure one of the best graphics cards or best mining GPUs. Kawpow algorithm with RVN as the main cryptocurrency entered the mining industry with a boom. Modding the card and replacing the VRAM thermal pads with thicker/better pads is possible and will help cooling and performance. Visit our corporate site (opens in new tab). that's good. The 3090 overclocking is identical to the 3080. Running with GPU clocks of 2.2-2.5GHz just wastes power and generates heat without improving performance. Note that Nvidia's RTX 30-series GPUs have "error detect and retry" on the memory, which can sometimes obscure borderline unstable overclocks, and we figured 21.5Gbps was sufficiently fast. Radeon RX 6900 XT (Reference): Tuning all three of AMD's reference RX 6000 cards ended up very similar. Mining Ravencoin (KAWPOW algorithm) is made simple with NiceHash Miner. Set it However, we still found we achieved the best result by dropping the power limit to 80-90% and then setting the GPU core clocks to the minimum possible value in MSI Afterburner (-502MHz). There's a lot to discuss with these charts, specifically, what do we mean by "tuned" performance? ago. There, you had to slowly increase the core and memory clock speeds to get the best result out of the whole overclocking process. In this video I go through the full process of overclocking AMD GPUs for mining. Use MSI Afterburner to overclock your video card. Increase the fan speed to 90% - 100%. The card has a powerful core, which is quite useless for Ethereum mining that doesnt require more than 700-800 MHz. Even though some algorithms may perform better than others, we're going to focus exclusively on Ethereum hashing for now. The 3070 normal consumption for mining is 130 W at the hash rate of 63 MH/s. Regardless of which GPU you're looking at, though, all of the GTX 1660 models benefit greatly from dropping the GPU clocks. We also tested a second game, Borderlands 3, at 4K and Badass settings with the same four GPU settings. To set up GPU overclocking, you need to install MSI Afterburner. Meanwhile, power can be very expensive for larger mining setups, and poor efficiency PSUs (power supply units) will generate more heat and use more electricity. As a result, he gained lots of practical knowledge and became interested in sharing it with others. jowwann 4 hr. Again, if you already have a GPU, putting it into service isn't a terrible idea it's your hardware, do with it what you please. It's also important to note that we're reporting raw graphics card power for the entire card, but we don't account for the power consumption of the rest of the PC or power supply inefficiencies. Check our guide on how to test graphics card performance, and you'll also want to check your graphics card temperatures and clock speeds. overclocking significantly increases power consumption. Follow the steps below to overclock your GPU while mining crypto: Download and install graphics card utility software. extremely high settings may damage your fan. GPUs demonstrate the considerable potential to surpass that speed. In-build overclocking: Auto-overclocking: TDP downclocking: Algorithm switching: Benchmarking: Remote start/stop: 3rd party miners: 3rd party dev fees: . First and foremost, you need to install overclocking software. It offers a good way to control system overheating and speed up overall PC performance. The pill makes memory less stable and lowers max overclocking potential. We went from stock to +1200MHz (compared to +750, which is about as far as we could go for gaming overclocks), giving a maximum speed of 16.4Gbps, with a 400MHz negative offset for GPU compute workloads. My personal mining fan configuration is either a curve of whenever the card is above 40 Degrees then go at a fan speed of 70% -100%, or continuously 80% fan speed. That might be noticeable, to some people, without running a bunch of benchmarks. That resulted in a 1747MHz clock compared to 2289MHz at stock, but fan speed was higher this time. It controls how much power your GPU can eat. Just keep in mind that the 3090 acts as the excessively overclocked 3080 with a weak power supply. Clean before you overclock If you're looking to overclock a card you've already installed, then it's. MH/s, 8.64 Going over the process I do to get the best efficiency settings using MSI Afterburner. Gaming * The 30xx series stats are up-to-date as of December 25, 2020. MH/s, 31.37 Everything was fine so far, and we applied a 100 MHz offset to the GPU core. MH/s, 33.15 +1000 MHz (21.5Gbps) also appeared stable, as did +1250 MHz (22Gbps), but +1500MHz immediately crashed our system and forced a system restart. Mining at this stage is far less profitable. After you successfully activate the pill or apply the mt parameter, follow the same overclocking process as with the 1060 and 1070. MH/s, 44.55 At some point when you lower PL, the core clock may start fluctuating, going below 1 GHz from time to time and then going back in a second. This program works on In practice, there's usually not enough headroom that it's worth the hassle. That resulted in actual GPU clocks of 960MHz on average. This isn't an necessarily an optimal miner PC configuration, but it will suffice and is a closer representation to what most of our readers are probably using. That gave us a GDDR6X temperature of 104C, which is still higher than we'd like, and performance remained at around 106MH/s. If you look at all the factors, the algorithm comes second best in terms of prominence and profitability in GPU mining after Ethash. The Ravencoin hash rate table below demonstrates the growth in popularity. The core is from 1100 to 1200, and the memory is from 950 lower until the graphics card becomes stable that is, up to 900 at intervals of 5.
