The frequency of clocks They will burn out if you run them that way. Note that outside of the RX 580 and 590, and the three GTX 1660 variants, all of our tests were done using the reference models from AMD and Nvidia, which tend to be more of a baseline or worst-case scenario for most GPUs. Nvidia decided not to update the 10xx GPU driver for Windows 7, so you cant mine Ether efficiently on Windows 7 using the 10xx GPUs. Case in point: Even though all the RTX 4090 cards (opens in new tab) we've seen so far appear to use Micron 21Gbps GDDR6X memory (opens in new tab) ("D8BZC" labeled chips), we've seen maximum stable memory overclocks range from 22.6Gbps to as high as 25Gbps. Radeon RX 6800 (Reference): With only 60 CUs (compared to 72 on the 6800 XT and 80 on the 6900 XT), you might expect the 6800 vanilla card to end up slower. Step 4 - Fine Tuning. MH/s, 44.55 If you want to learn more about the overclocking process and GPU settings for mining, keep reading. We again dropped the GPU core the maximum allowed (-502MHz), set the memory clock to +750MHz, and put the power limit at 70%. We'll forgive you if that feels underwhelming. In fact, based on past personal experience that some of us have running consumer graphics cards 24/7, it is absolutely possible to burn out the fans, VRMs, or other elements on your card. MH/s, 105.0 MH/s, 8.68 Heres how it works. When you purchase through links on our site, we may earn an affiliate commission. MH/s, 35.04 All PoW networks (Proof of Work) pay miners with their coins for this job. The process involves three main steps: downloading and installing the HiveOS software, selecting your desired settings, and then saving and rebooting your system. The first step is to overclock the memory to the stable maximum. More miners in the network ensure better protection and make attacking the network more difficult or even impossible due to the lack of necessary mining equipment in the world (that is, an attacker cant rent enough graphics cards to cover 50% of the network hash rate). gradually by 100, then mine for 10 minutes and repeat incasing until any Overclock setting will be different for different mining algorithm. Graphics card - NVIDIA: Graphics card - AMD: CPU - AMD: CPU - Intel: Rig . Going over the process I do to get the best efficiency settings using MSI Afterburner. That might be noticeable, to some people, without running a bunch of benchmarks. There are a few things you should know before getting started. Why tomshardware promote scams??? Overclock and share. Shifting over to AMD, everything was very close on performance within 2% across all four cards. Just follow the steps described below: Still, keep in mind that overclocking may lead to hardware overheating, reduces the lifespan of a graphics card, and increases the noise level. taking electricity price into account, with our Mining Calculator GPU. It doesn't like stock settings, as the GDDR6X gets very toasty. If you've pulled up data using a mining profitability calculator, our figures indicate there's a lot of variation between power and hash rates, depending on your settings and even your particular card. that's good. Without altering the cards, the Nvidia 3080/3090 Founders Editions let the memory get very hot while mining, which can dramatically hinder performance and/or reduce the card's lifespan. The 2060 Super and 2070 Super both had to run with a +1100 MHz offset in MSI Afterburner, giving an effective speed of 15.8Gbps (with a 400Mbps negative offset for compute). MH/s, 33.0 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. Repeat increasing until any instability occurs. Paying extreme prices for mid-range hardware to try and build your own personal mining mecca, on the other hand, is a big risk. That gives an effective memory clock of 21Gbps, and after several minutes of running around in the game, we figured it was working fine. That's because Ethereum hashing depends quite heavily on memory bandwidth. MH/s, 23.53 The graphics cards that cant mine Ether anymore are relatively good at mining Ravencoin RVN (well discuss it later). We set the power limit to 75%, increased the GDDR6 clocks by 1250MHz, and ended up with a relatively high fan speed of around 80% with the default fan curve. Here, the lower power RTX 3060 Ti and 3070 shoot to the top, and then there's a moderate step down to the RTX 3060, 3080, RX 6700 XT, RX 6800, and so on. Kawpow algorithm with RVN as the main cryptocurrency entered the mining industry with a boom. This article will provide you with the information on how to overclock your Nvidia RTX 3080 graphics card for a best performance and Hashrate/Watt efficiency and Ethereum mining. * - Our GTX 1070 and GTX 1080 are original Founders Edition cards from 2016 and appear to perform far worse than other 1070/1080 cards. Don't be surprised if you don't reach the level of performance others are showing. We were relatively close on the 3060 Ti performance, and our earlier power data showed much better results than NiceHash, but now those figures have been updated and are slightly lower than our measured power. Factor in power efficiency and things are much closer. However, stability is important to me, and my setup had been working for 18 days without crashing. If you want to know how to mine Ethereum, we cover that elsewhere, but the "how" is quite different from the "why." This is supposed to make . To mine efficiently in 2021, you need a GPU with at least 5GB of RAM. In this video I go through the full process of overclocking AMD GPUs for mining. Best Mining GPUs Compare the profitability and payback of all video cards in the Best Mining GPUs table More overclocks can be seen in other languages: But if you need it asap or you dont feel like getting into details, use our table. Activate mining. Plus, it's a simple flip of a switch rather than something that requires a lot of trial and error. We found the best GPU overclocking settings for Nvidia and AMD and put them on the table. It's important to note that as you are overclocking and testing, always monitor the GPU temperature. In AMD Software, select Performance from the top menu then choose Tuning from the sub-menu as highlighted in the example below. Finally, we have temperatures. MH/s, 9.5 extremely high settings may damage your fan. The card has a powerful core, which is quite useless for Ethereum mining that doesnt require more than 700-800 MHz. The best thing to do is to disable CUDA P2 state through the nvInspector tool (more specifically, through its nvProfileInspector subtool). We set the maximum GPU frequency to 50% and ramped the VRAM clocks up by 150MHz, which resulted in actual clocks of around 1300MHz while mining. The answer: It varies, often massively, by GPU. MSI afterburner is the most popular GPU overclocking software and it's free. Our Vega cards are also reference models and were far more finnicky than other GPUs. However, where previously you could theoretically net over $10 per day on a 3080 or 3090 card, current profitability has dropped significantly, and less than $4 per day for a 3090 is typical. More importantly, power consumption took a massive dive, and efficiency improved to one of the better results in our testing. We've included Nvidia's RTX 20-series, GTX-16-series, and GTX 10-series cards, along with AMD's RX 5000, Vega, and 500 series parts. Start lowering PL by 1%. +400 MHz and +800 MHz. This is the core GPU speed. ThunderMaster is a feature-rich and powerful GPU overclocking software from Palit. MH/s, 31.37 Most importantly, at the same (relatively) performance as the 3080 FE, GDDR6X temperatures stabilized at 100C. He has been working as a tech journalist since 2004, writing for AnandTech, Maximum PC, and PC Gamer. In this case first you need to restore the operating mode after reloading, and only then activate mining. At stock, the 3080 and 3090 Founders Edition cards both hit 108-110C on the GDDR6X, at which point the GPU fans would kick up to 100% (or nearly so). Start raising the memory clock little by little at +50 MHz intervals. 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. It can happen approximately in 1.5 years. You can also ask the drivers to overclock the VRAM or the GPU but not both. To customize GPU performance tuning settings globally, follow these steps: From the taskbar, click the Start button (Windows icon), type AMD Software and select the app under best match. The reality is that AMD and Nvidia and their graphics card partners tend to bin the chips and push performance nearly to the limit. Why? You can use it to overclock your graphics card, clock speed, and adjust voltage settings and fan speed. MH/s, 10.71 Compare the profitability and payback of all video cards in the Best Mining GPUs table Kryptex. We tried maxing out the core voltage after restarting the game, and it still crashed, which means a 150 MHz offset won't work. Not that hard to get one if you know where to look. Also, our results on the reference blower cards are probably far less than idealjust about any custom Vega card would be a better choice than these blowers. The fans on consumer cards aren't designed to spin at 100%, 24/7 without failing. This is just a baseline set of performance figures and data, using our specific samples. MH/s, 35.0 It should be around 7500 MHz. NVIDIA GPUs, you add value to the default value, while in AMD you set the The card in stock produces 20.3 Mh / s on the air, while the power consumption is 95 watts. Like @Phaaze88 said, you need some custom cooling and modding to overclock these days and the gains will be minimal. Default clock : 1100MHz. 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.
