However, it's important to note that this step is optional. . NY 10036. This is the core GPU speed. As such, our maximum hash rates ended up about 10% lower than what some places show. New York, The article is up-to-date as of the beginning of March 2021. To mine efficiently in 2021, you need a GPU with at least 5GB of RAM. As a result, he gained lots of practical knowledge and became interested in sharing it with others. The reality is that AMD and Nvidia and their graphics card partners tend to bin the chips and push performance nearly to the limit. The basic GPU setup for Ethereum mining is quite simple. 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, 12.5 mind that extreme temperatures and clocks can irreversibly damage your 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. Our Vega cards are also reference models and were far more finnicky than other GPUs. It offers a good way to control system overheating and speed up overall PC performance. When you purchase through links on our site, we may earn an affiliate commission. Just because one person with a "HappyGPUs RTX 4090 X-Factor-Wow" model card (that's a made up name, if you couldn't tell) managed a 20% core overclock and a 25% memory overclock doesn't mean that every HappyGPUs RTX 4090 XFW card will hit those same clocks. That's because EVGA appears to have put a lot of effort into cooling the memory. Kawpow algorithm with RVN as the main cryptocurrency entered the mining industry with a boom. Temperature limit. We've had it crash, and we've had it generate unstable overclocks as well. ago. the following settings: Usually, NVIDIA cards It can happen approximately in 1.5 years. Well explain how to overclock graphics cards to maximize profit and do it right for different algorithms. The max core clock is achieved by the increasing voltage which leads to a proportional increase in GPU power consumption. Furthermore, RVN is featured on many major exchanges. I start by finding the maximum "stable" core clock, then I find the maximum "stable" memory clock, and then I try to find a blend of the two that results in optimal performance. That resulted in a 1747MHz clock compared to 2289MHz at stock, but fan speed was higher this time. You might do fine, you might do great, or you might end up with a lot of extra PC hardware and debt. Aye, Nvidia's Gpu Boost already squeezes most of the core clock OC out of their gpus. Meanwhile, the RTX 3060 Ti and 3070 cards started at close to 52MH/s even though the 3070 is theoretically faster. Kaspa Dual Mining with Nvidia 3070. absolute value. Then lower PL. The fastest GPUs for Ethereum mining right now are the RTX 3080 and RTX 3090, by quite a large margin. The card in stock produces 20.3 Mh / s on the air, while the power consumption is 95 watts. MH/s, 104.12 If you don't mod the card to improve GDDR6X cooling, you'll typically end up at 106-110C (depending on your card, case, cooling, and other factors), and the maxed out fan speed is not going to be good for fan longevity. The cards settled in at 106 degrees Celsius, with GPU clocks fluctuating quite a bit. MH/s, 35.0 So Windows doesnt help you get a better hash rate. By using -forcePState:0,0 command in the Nvidia Inspector you can get 61 MH/s at the consumption of 107 W, or 570 MH/s per kWh. I've lost countless hours troubleshooting my PCs, and these days I just don't find GPU overclocking to be particularly important. Its the mt parameter in t-rex that goes from 0 to 6. Which brings us toa card that we've since removed from the charts. Also, don't go into GPU overclocking expecting a 20% improvement or more in performance, because those days are far in the past unless you use liquid nitrogen. Nvidia has managed to undo some of those gains with updated drivers, however, so newer cards like the RTX 3050 might not be all that great. Of course, as with any overclocking, care should be taken to avoid running your GPU at unsafe settings. Like Nvidia, AMD's GPUs are largely limited in performance by their memory speed, and without tools to overclock beyond 17.2Gbps, there's not much to be done. Corsair 2x16GB DDR4-3200 CL16 (opens in new tab) 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. The RX 5600 XT is the same GPU but with a 192-bit memory interface, which cuts performance down by about 25% again, right in step with memory bandwidth. On the 3080, the FE ended up just 2% slower while using 6% more power. In that case, it might be worth considering, particularly if you live in an area where power isn't super expensive. The graphics cards that cant mine Ether anymore are relatively good at mining Ravencoin RVN (well discuss it later). And then there's Polaris. OpenBenchTable. We mined separately Kaspa (KAS), Ethereum Classic (ETC), and Ergo (ERG) and then dual mining combinations such as Ethereum Classic + Kaspa and Ergo + Kaspa. It's just so competitive between AMD/Intel/NVIDIA that they squeeze every ounce of performance out of there hardware at stock. We got 32MH/s, up from about 28MH/s at stock, with power draw of 75W. This year we expect a lot of new GPU releases. MH/s, 6.4 Suppose you already have a graphics card and want to mine using your GPU's spare cycles. Seasonic Focus 850 Platinum (opens in new tab) If you can keep your GPU and other components cool, they'll last longer and not break down as often. Lets see how to overclock AMD graphics cards from its new and quite effective series. Lower the memory voltage. It's important to note that with each new Ethereum epoch (they change every four days) energy consumption of Nvidia GTX 10xx graphics cards will increase by a bit until it reaches the GPU max power limit. Whatever is going on behind the scenes, it appears different AMD Navi 21 GPUs run optimally at different "maximum frequency" settings. 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. Mining pools for professionals by professionals, Nvidia and AMD GPU Overclocking Settings for Ethereum Mining, How to Overclock a GPU for Ethereum Mining, Mining with Nvidia on Windows (P2 and P0 States), Ethereum Mining on Pascal (GTX 10xx Series), Ethereum Mining Overclocking on the Nvidia GeForce GTX 1060 (6GB), 1070, 1070Ti, Ethereum Mining on the Nvidia GeForce GTX 1080 and 1080Ti, Ethereum Mining on the Nvidia GeForce GTX 16xx and 20xx, ETH Mining on the Nvidia GeForce RTX 30, Ethereum Mining on the Nvidia GeForce RTX 3070, Ethereum Mining on the Nvidia GeForce RTX 3080, Ethereum Mining on the Nvidia GeForce RTX 3090, AMD RX 5 and 6 Overclocking for Mining, Energy Efficiency in Mining. Start raising memory clock little by little at +50 MHz intervals. The 1660 Ti and 1660 Super are basically the same speed, though we had better luck with memory overclocking on the Super. There's a reason people do this, and results can vary quite a bit depending on your specific hardware. These days, it would take more than a year at current rates, assuming nothing changes. If you are also thinking about cryptocurrency mining and you are planning to use Nvidia graphics cards, this article is for you. We tried maxing out the core voltage after restarting the game, and it still crashed, which means a 150 MHz offset won't work. 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. (In some cases, you can also adjust memory voltage.) At one point, it might have been possible to break even on the cost of a new GPU in a few months. Afterburner works on any GPU regardless of brand (no need to buy an MSI version of the GPU). Click on the link above, download and install. Disassembling the GPU might void the warranty or/and might permanently damage the GPU. That yielded similar hash rates of 93MH/s, while fan speed, GPU temperature, and power consumption all dropped. Check our guide on how to test graphics card performance, and you'll also want to check your graphics card temperatures and clock speeds. Our stance is that this is a Very Bad Idea (tm). Most cards won't go much beyond around 1800MHz on GDDR6 clocks, which is equivalent to 14.4Gbps, though some might be able to do 14.8Gbps. Start raising the core clock little by little. Tom's Hardware is part of Future US Inc, an international media group and leading digital publisher. Power limit. After tuning, the RX 6600 XT basically gets about 2/3 the hashrate of the RX 6700 XT. We were able to add 1200MHz, giving a 16.4Gbps effective speed in theory, but the memory actually ran at 16Gbps (vs. 13.6Gbps at stock settings). GPUs demonstrate the considerable potential to surpass that speed. Except we still ended up at the same 44MH/s hash rate. How to overclock a graphics card for mining First and foremost, you need to install overclocking software. You can try setting it to reference design, standard MSI, extended MSI, or third party some cards will only allow voltage adjustments with the correct mode, and some might not allow it at all. Start raising the memory clock little by little at +50 MHz intervals. performance. The 2Miners pool co-founder, businessman, miner. More about graphics reviews testing and news about gpus, should change the name of the article to: How to disenfranchise and lose your target audience. Hot algorithms mostly use GPU core, so their performance depends on the core clock. As someone who has done a lot of overclocking over the years, I can say that one of the worst feelings is when you're in the middle of a game and it suddenly crashes due to a formerly "stable" overclock. But out of the box, these are numbers that just about any card using one of these GPUs should be able to match. and AMD GPUs has some slight differences. We've run these benchmarks using NiceHash Miner, looking at actual realtime hash rates rather than the results of its built-in benchmark. 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: Again, non-reference cards often perform a bit better, and if you want to research VBIOS flashing and hardware modding it's possible to hit higher hash rates. It has a user-friendly interface and works with any Nvidia or AMD GPU. At stock, the fans end up running at 100% to try to keep the GDDR6X below 110C, and that's not good. MH/s, 14.16 So for CUDA, Nvidia designed a special lower memory clock state (P2). 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. +1000 MHz (21.5Gbps) also appeared stable, as did +1250 MHz (22Gbps), but +1500MHz immediately crashed our system and forced a system restart. MH/s, 25.62 We'll list our optimized settings below, but here are the results. You can save the results as links to 2CryptoCalc that allows you in just a few clicks to evaluate whether your algorithm is better or worse than alternatives in terms of the current mining profitability specifically for your rigs. MSI afterburner is the most popular GPU overclocking software and it's free. MH/s, 21.3 Additional tuning improved the 3080 performance to 93MH/s, while the 3090 FE limited us (on memory temps) to around 106MH/s. Download CPU overclocking software. We again dropped the GPU core the maximum allowed (-502MHz), set the memory clock to +750MHz, and put the power limit at 70%. Just keep an eye on your GPU and VRAM temperatures, and don't forget to give your PC a regular cleaning to keep it running smoothly. The vanilla 1660 with GDDR5 memory doesn't clock quite as high on the VRAM and thus performs worse on Ethereum mining. We split the difference and dropped to 125 MHz, which also crashed. Set it With that initial performance boost in play, we then tried a 150 MHz core overclock and Cyberpunk 2077 almost immediately crashed. MH/s, 45.0 I mean look.. Heres how it works. You're then in the unenviable position of wondering if there's a bug in the game, if your overclock pushed too far, or if there's something else wrong with your PC. Why tomshardware promote scams??? Overclocking & Undervolting AMD GPU For MiningLooking for ways to overclock & undervolt your AMD GPU for mining? You'd think that wouldn't be sufficient, but boosting the GPU clocks up to 1.9GHz resulted in the same performance while substantially increasing the amount of power used. Overall, the 5700 and 5700 XT end up as the most efficient previous generation GPUs for mining. Not that hard to get one if you know where to look. Complete Guide to Overclock Nvidia GPUs for GPU Mining. You can do everything you need, specifying voltages, clock speeds, fan speeds, memory speeds, and more. We didn't record 'stock' performance, but it was around 41MH/s. You don't have to agree with me, however; perhaps your particular hardware will deliver a bigger boost in performance after tuning. Use MSI Afterburner to overclock your video card. At some point, the speed will start falling. Kernels <5.5 have issues with Navi and Navi2 cards with the sysfs interface. Follow this guide. One option for overclocking is to use the automatic OC scanner tool. The 1080 and 1080Ti feature high-timing fast GDDR5X memory that initially wasnt as good at Ethereum mining as GDDR5. The problem was fixed for the 16xx, 20xx, and 30xx. Find the limit after which the core starts fluctuating and falling below 1 GHz. NY 10036. Unlink Power Limit and Temperature Limit [1 on the image above]. AMD's cards ran hot at stock settings, but all of the cards benefit greatly from tuning.
