We'll get into the clocks and speeds momentarily, but we think your best long-term bet is to let GPU temperatures hit at most 70C, preferably less. VRM temperatures should be kept to a maximum of 90C again, preferably less , and we definitely wouldn't run with GDDR6X temperatures of more than C and expect a card to remain viable for much longer than a year. Maybe that's pessimistic, but we've had graphics cards fail far faster than that in the past, so better safe than sorry is our motto. Again, we think if it's above C, that's too hot for long-term reliability. And no, we're not going to play guinea pig!
Some totally failed and some were just very unstable. Nearly all of them had fans go bad, and RMAs were a complete pain. It took weeks to get a card back, and some manufacturers even refused warranty service "due to physical damage" or other such claims.
The manufacturers are going to see higher RMA rates with another mining boom, and some will use any reason to deny a claim that they can find. Now that we've talked about temperatures and fan speeds, let's talk about overclocking — or even underclocking and undervolting. Memory speed is a key factor in Ethereum mining performance. While tuning memory clocks, you want to pay attention to long-term hash rates. An RTX with memory running at 20Gbps and a 1. Drop the GPU clocks to 1. This means you can hit higher clocks that aren't unstable, but memory performance actually degrades past a certain point.
Trying to balance memory clocks against power and temperature is complex, and it's definitely possible to find 'stable' clocks that will end up causing problems down the road. One reasonable approach is to find the maximum stable memory overclock, by bumping the clock speed up in 50—MHz increments and letting the mining run, until you get errors or a system crash.
Besides overclocking of the memory, you should look into underclocking and undervolting of the GPU, particularly for AMD's previous-generation cards. The Vega and Polaris families are very power hungry at default settings, and it's often possible to drop the voltage by 0. That's a huge difference, especially since power scales with the square of the voltage. You'll probably need to reduce maximum clocks while reducing the voltage, but the dramatic boost in efficiency makes the effort worthwhile. Ultimately, the goal of miners is to maximize profits, taking all things into consideration.
That means balancing the cost of the hardware, memory speeds, GPU clocks, pool mining fees or NiceHash fees , power consumption, time required to manage the mining PC s , the cost to service or replace hardware, and more. Figuring out the optimal balance between all of those factors is complex, and while it might seem tempting to chase after every last bit of hashing performance, that may not be the best long-term solution.
If you're building a larger mining farm again, not something we recommend for a variety of reasons , efficiency will be a top priority. Two Ti cards for example will basically match a single RTX while using less than half as much power. But let's take things a step further.
That's only a rough estimate and does not include AC or other items that potentially need power.
Which algorithms and software get tested varies a bit by your GPU, and you can customize things quite a bit. A minimum payout is the smallest amount of Ether you will need to mine before it gets sent to your wallet. We'll answer those questions as best we're able, and bring up other concerns and related information that you might not have considered. Ok, now that we have that out of the way how do you start mining Ethereum? Reasons to avoid - Variety of ports can be confusing - High specs mean high price tag.
But what would those mining farms cost? We've put together a rough estimate of hardware costs per PC. Plus all the GPUs, naturally, at current eBay prices. Yeah, that's a ton of money.
Power estimates based on our testing indicate the Ti PC would use about W, including PSU inefficiency and the rest of the PC, while the would need around W and the would consume W. Based on those prices, power use, and hash rates, we can determine approximate break-even time not including rental space or AC. If that sounds too good to be true, it is. Warehouse space to accommodate all those PCs, power distribution, and paying someone even yourself to build and maintain all the PCs is also necessary.
Those would add thousands of dollars per month in cost, pushing back the break even point, and if things take a change for the worse as they did in and , the whole operation comes crashing down. Bottom line: We're not big fans of large cryptocoin mining farms. There are arguably worse ways to use power and money, but there are also a lot of better ways — ways that don't carry nearly the volatility and risk of coin mining. Never mind the fact that procuring all of the necessary equipment takes time and a lot of money, or that it makes it difficult for PC enthusiasts to upgrade their PCs.
The bigger issue, by far, is that it's putting a ton of computing power to the task of merely securing the blockchain. Best-case, using the most efficient hardware, the Ethereum network would currently use about a billion watts of power, and Bitcoin would use 5. Digiconomist pegs the current power use of the Ethereum network at around 21 TWh per year, and 45 kWh per transaction. It's even worse for Bitcoin — much worse — but we'll leave that discussion for others. Looking at all the costs and power going into these networks, it's difficult to remain optimistic about their long-term potential.
We're strip-mining digital coins, basically, and that's unsustainable. At some point, this all hits a plateau, and short of zero point energy or some future technology that allows for clean power far beyond what we currently use, there's a very good chance the viability of mining eventually stops.

Maybe that's not this year or next year, but the growth in hash rates, power use, and prices obviously can't go up indefinitely, and it won't. Cryptocurrency networks are designed to find a 'stable' equilibrium, which effectively means getting enough people to believe in and use the coin to make it viable. Equilibrium almost certainly isn't going to be highly profitable. Do you still want to mine? By all means, have at it. We've provided the information here that allows you to get started. We've also provided a less optimistic view, so you'll hopefully more fully understand the risks.
We also recommend mining at conservative settings until you've at least paid for the hardware you bought. Once you're in the black, feel free to crank up clocks and fan speeds and see how long this crazy cryptocurrency ride remains viable. Don't be surprised if that's not nearly as long as you'd need to turn a healthy profit, as that ship likely already sailed. Image 1 of 3. Image 2 of 3. Image 3 of 3.

This has to stop. Thank you so much for this article! I knew it was ridiculous but I didn't know it was that bad. You could pull a ton of people out of poverty permanently with the money spent on mining!
Making small loans to entrepreneurs would generate more profits I'm sure. Think of all the "startups" that could sell out and make a huge profit. Title should be "How to cripple environment, distort market and make enemies". Many economists have likened the major "mined" cryptocurrencies to pyramid schemes. You make the most money based on people who enter after you. Therefore, whenever you see someone post information on how to get into cryptocurrency, be wary that they may not have your best interest at heart.
Etherium is in a transition from "proof-of-work" i. This will make it even less profitable to mine it and maybe mining will stop completely but will still benefit those who are already higher up in the pyramid.

Nvidia said it had intervened to make sure its products "end up in the hands of gamers". But several factors, including manufacturing delays during the coronavirus pandemic, have contributed to a shortage. Graphics cards are also popular with crypto-currency investors, who can use them for processing transactions and generating bitcoins, in a process known as mining. Many miners build rigs using several graphics cards at a time to produce a powerful machine dedicated to mining crypto-currency, rather than gaming.
For this to be economical, the rig must generate more in bitcoins than the cost of the hardware and the electricity it uses to run. Nvidia said it had focused on Ethereum because it "has the highest global mining yield for any GPU-mineable coin at the moment and thus is likely the main demand driver for GPUs in mining". Nvidia implemented a special system to reduce the hash rate of Ethereum mining on its new RTX graphics card last month.
It was supposed to limit mining performance by around 50 percent , but multiple reports now claim cryptominers have bypassed the protection. Andreas Schilling, an editor at Hardwareluxx , has also backed up these findings. The beta driver appears to unlock Ethereum mining performance across a variety of RTX cards, which was likely not what Nvidia had planned for its test drivers. The Nvidia originally restricted RTX mining performance in an attempt to steer cryptominers away from purchasing the cards.
The beta driver bypass of Ethereum mining performance will certainly make the cards more attractive to cryptominers now. Nvidia seemed confident in its software restrictions to nerf RTX mining performance.
