Reduces the load on the GPUs if possible. Can be set to a comma separated string to enable the mode for a subset of the GPU list eg: --low-load 0,0,1,0 --dual-algo Second algorithm to use in dual mining mode. See dual mining guide for more details.
Example: --profit-per-mh 0. Range from 10 to Valid values: off - auto-tune is disabled. LHR tune value is fixed during mining, and will not change no matter how often LHR lock is detected down - LHR tune value will decrease if the miner detects LHR lock full - same as "down" but additionally miner will be trying to increase LHR tune value if it's stable on the current LHR tune level --lhr-autotune-step-size LHR auto-tune step size default: 0.
Range from 0 to 5. Set to 0 to enable auto-tuning: the miner will benchmark each kernel and select the fastest. Can be set to a comma separated list to apply different values to different cards. Valid values: 0 - auto defaults to 2 1 - single each ERGO block the GPU stops hashing until it generates the dataset 2 - double the miner generates the dataset for the next ERGO block before it arrives with a small penalty to reported hashrate, and when the next block does arrive, it immediately starts hashing without losing seconds on creating the dataset.
Memory requirements are doubled in this mode as the GPU has to hold two memory buffers. If there is not enough memory on the GPU for two datasets, the miner will fall back to single buffer mode. Domain names are resolved through the proxy too. Example: 55,65 - it means that temperatures above 55 will have yellow color, above 65 - red color. Set to 0 to disable. For external access set IP to 0. Use "--api-generate-key" to generate it.
Enabled by default if "--api-key" isn't set. The output key is used as a value for "--api-key". Use this option along with "-c" to write api-key directly into your config file. Minimum is 5 sec. No GPU stats at all. Also enables share diff info. Format: N:M:A.
Valid values: N: any positive integer, M: any positive integer, A: r system reboot , s system shutdown , e miner exit Actions "r" and "s" require running the miner with administrative privileges. Examples: s - watchdog will shutdown the system if the miner gets restarted 20 times within any 10 minute interval r - watchdog will reboot the system if the miner gets restarted 5 times within any 7 minute interval -B, --benchmark Benchmark mode.
Only applicable for ProgPOW family of algorithms. Parameter is set in seconds. Requires running the miner with administrative privileges. Range from 0 to 6. General recommendation is to start with 1, and then increase only if the GPU is stable. The effect is similar to that of ETHlargementPill. Example: --mt 4 applies tweak mode 4 to all cards that support this functionality --mt 3,3,3,0 applies tweak mode 3 to all cards except the last one GPU fine tuning Windows only All options can be set to a comma separated list to apply different values to different cards.
Will be set to 0 on exit and during DAG rebuild. Mostly, we're looking at the data based on current market conditions. Predicting where cryptocurrencies will go next is even more difficult than predicting the weather, politics, or the next big meme. If you don't already have the hardware required to get started on mining today or really, about eight months ago , you're late to the party.
Like the old gold rush, the ones most likely to strike it rich are those selling equipment to the miners rather than the miners themselves. If you've looked for a new or used graphics card lately, the current going prices probably caused at least a raised eyebrow, maybe even three! Our GPU pricing index has additional details, but the market had a perfect storm of pandemic induced shortages and increased demand, and mining only made a bad situation worse.
Then I looked at prices and realized my old card is selling for as much as I paid over three years ago! Pascal and Vega cards from three or four years ago are currently selling at close to their original launch prices — sometimes more. If you've got an old graphics card sitting around, you might even consider selling it yourself though finding a replacement could prove difficult. The good news for those not interested in mining is that profitability has dropped, and GPU prices followed suit to a lesser degree.
Now more than ever, we strongly discourage people from trying to strike it rich with crypto mining. Ethereum should make the switch to proof of stake some time before July maybe , plus there's the environmental cost to consider. But the cryptocurrency market is nothing if not extremely volatile, and many are willing to take a risk now in hopes of scoring a big payoff later. Ultimately, we know many gamers and PC enthusiasts are upset at the lack of availability for graphics cards, but we cover all aspects of PC hardware — not just gaming.
We've looked at GPU mining many times over the years, including back in , , and Those are all times when the price of Bitcoin shot up, driving interest and demand. The only prediction we're willing to make is a lovely tautology: Prices on Bitcoin and Ethereum will change in the months and years ahead — sometimes up, and sometimes down. And just like we've seen so many times before, the impact on graphics card pricing and availability will continue to exist.
Proceed at your own risk. With that preamble out of the way, let's get to the main point: What are the best mining GPUs? This is somewhat on a theoretical level, as you can't actually buy the cards at retail for the most part, but we have a solution for that as well. We're going to use eBay pricing — on sold listings — taken from our GPU pricing index.
How much can you make by mining Ethereum with a graphics card, and how long will it take to recover the cost of the card using the currently inflated eBay prices? Let's take a look. For this chart, we've used the current difficulty combined with the average price of Ethereum over the past week — because nothing else is coming close to Ethereum for GPU mining profitability right now. We've optimized Ethereum mining performance , with an eye toward minimizing power consumption while maximizing hash rates.
Also note that we're using real-world in-line power measurements for the GPUs, collected using our Powenetics hardware and software solution , so our power figures are not relying on software data, which can be off by anywhere from a few watts to over 50W, depending on the GPU. Taking the hash rate and current difficulty, we subtract the power cost to come up with daily profits. Then we used the approximate eBay price divided by the current daily profits to come up with a time to repay the cost of the graphics card.
The following table is sorted by time to break even assuming price and difficulty don't change, which they absolutely will. Last time we updated this list, the best-case scenario for breaking even required as little as days. With the decrease in Ethereum prices combined with the increase in mining difficulty, at current rates your best bet would be just over a year to break even — which will of course change, because cryptocurrencies are nothing if not volatile. Keep in mind that Ethereum is still supposed to transition to proof of stake i.
That transition has been delayed a couple of years now, though, so who knows when or even if it will ever happen? Six months from now we could see substantially lower profitability, if GPU miners are forced to find alternatives to Ethereum. Miners likely hope that some other coin will take off and replace Ethereum, but that's yet another gamble.
Also note that finding some of the older model cards in sufficient quantities may be more difficult, and running multiple GPUs off a single PC requires PCIe riser cards and other extras that add to the total cost. Not surprisingly, Nvidia's LHR model cards tend to do far worse overall. Break-even times currently range from just under days to as much as days, depending on the GPU.
Unless the current Ethereum pricing trend reverses, you can expect it to take even longer, especially when you factor in the other hardware you'd need. For pure graphics card power, you should divide the numbers in the table by your PSU's efficiency rating e.
If you're running multiple GPUs off a single PC, total waste power would be somewhat lower, though it really doesn't impact things that much. If you take the worst-case scenario and add 60W to every GPU, the time to break even increases by 20—30 days. It's also fair to say that our test results are not representative of all graphics cards of a particular model. VBIOS mods may help use at your own risk , and some models simply run better and faster. Most of the remainder of the article hasn't been touched since around July , though we did tweak a few of the prices and break-even time estimates.
The problem is that the above table has no way of predicting the price of Ethereum, other coins, or mining difficulty. Guessing at the price is like guessing at the value of any other commodity: It can go up or down at a moment's notice, and Ethereum, Bitcoin, and other cryptocurrencies are generally more volatile than even the most volatile of stocks. On the other hand, mining difficulty tends to increase over time and only goes down when people stop mining like with the China mining crackdown , as the difficulty is directly tied to the network hash rate i.
The above is something of a best-case scenario for when you'd break even on the cost of a GPU. Actually, that's not true. The best-case scenario for miners is that the price of Ethereum doubles or triples or whatever, and then everyone holding Ethereum makes a bunch of money.
Until people start to cash out and the price drops, triggering panic sells and a plummeting price. That happened in with Ethereum, and it's happened at least three times during the history of Bitcoin. Like we said: volatile. Still, there are obviously plenty of people who believe in the potential of Ethereum, Bitcoin, and blockchain technologies. Even at today's inflated GPU prices with mining profitability slumping, some people are likely still making a go at mining.
