Miners provide protection to cryptocurrencies against the potential set on or cancelation of a transaction. More miners in the network ensure ameliorate protection and make attacking the network more difficult or fifty-fifty impossible due to the lack of necessary mining equipment in the earth (that is, an attacker can't rent enough graphics cards to cover 50% of the network hash rate).

All Pow networks (Proof of Piece of work) pay miners with their coins for this job. They either issue coins or take them from transaction fees. When miners find a new cake in the cryptocurrency network, they go a advantage plus transaction fees included in the block

What to Mine in 2021

At the end of 2020 – commencement of 2021, Ethereum has been the almost assisting coin in mining. It is known as Ethereum or ETH. Miners also call information technology Ether.

To mine efficiently in 2021, you need a GPU with at least 5GB of RAM.

The graphics cards that can't mine Ether anymore are relatively good at mining Ravencoin RVN (nosotros'll discuss it later).

Nvidia and AMD GPU Overclocking Settings for Ethereum Mining

If you lot are not willing to go into the setup details and just looking for terminal values, you can find them in the tables below. We still recommend reading the whole article so that you sympathise how GPU overclocking and setup for mining works. The article will help you apply more precise settings to your GPUs, get a higher hash rate, and subtract free energy consumption, thus maximizing your profit. But if you need it asap or you don't feel like getting into details, utilize our table. To fix GPU overclocking, you need to install MSI Afterburning.

Nosotros establish the all-time GPU overclocking settings for Nvidia and AMD and put them in the table. The columns incorporate a model, cadre clock, memory clock, power limit, and expected performance. Hither are Nvidia overclocking settings.

Here are AMD overclocking settings.

If you want to learn more most the overclocking process and GPU settings for mining, keep reading.

How to Overclock a GPU for Ethereum Mining

Information technology'southward important to annotation that as you are overclocking and testing, always monitor the GPU temperature. You tin just mine Ether safely if the core temperature is below 65 degrees. If it's higher, you lot are mining at your own risk.

The basic GPU setup for Ethereum mining is quite simple.

1. Start, we should identify the max retentiveness clock at +25 MHz intervals. Discover the clock value that makes the GPU driver crash (reload), move fifty MHz downwardly to the stable area.
2. Detect the core voltage that volition requite you the desired GPU free energy consumption. Lower voltage results in lower consumption, simply too in lower max hash rate. Relationship is not proportional. When you lower the consumption past 20–25% from standard, the speed decreases just by ten–15%.
3. Notice the max stable cadre clock (at +25 MHz intervals), move 25 MHz downward from it.

Fine tuning would give us additional two–6% of hash rate or ii–4% of energy efficiency. We will not go into more item in this article.

The instructions in a higher place are good for whatsoever AMD GPU. It'due south a bit trickier to prepare high-efficiency mining for Nvidia, then we will await at each serial separately.

Mining with Nvidia on Windows (P2 and P0 States)

At that place is an outcome with Nvidia graphics cards on Windows. The GPU memory at a standard clock commits a few errors that are not critical when rendering images in games, but they may be critical when making verbal calculations. So for CUDA, Nvidia designed a special lower retentivity clock state (P2).

GPUs switch to this state automatically, but miners ofttimes effort to maximize hash rate by overclocking memory significantly to +700, +grand, or even more. Nosotros accept a situation where P2 lowers the clock, while a mining device increases it at the same fourth dimension. The mining device keeps working, only when you turn information technology off, P2 switches dorsum, while manually added overclock remains. This leads to clocks that GPUs can't manage. As a issue, the driver crashes when you lot turn off or restart the mining software.

It's important to note that switching from P2 to P0 doesn't make a hash rate higher. It simply enhances stability when you plow your mining software on or off and reboot it.

The all-time matter to practice is to disable CUDA P2 country through the nvInspector tool (more specifically, through its nvProfileInspector subtool). Find CUDA Force P2 state parameter, disable it, and launch your miner.

Another important thing is that Force P2 state is restored anytime you install a new Nvidia graphics card, so make certain to double bank check.

Ethereum Mining on Pascal (GTX 10xx Series)

The 10xx series wasn't designed for mining, so in 2020 miners with the 10xx cards experienced a driblet in hash rate when mining Ethereum. Miners had to increase energy consumption to maintain hash rate which affected free energy efficiency.

It'southward important to annotation that with each new Ethereum epoch (they modify every iv days) free energy consumption of Nvidia GTX 10xx graphics cards will increase by a flake until it reaches the GPU max ability limit. Information technology tin happen approximately in i.5 years.

Nvidia decided not to update the 10xx GPU commuter for Windows 7, so you lot can't mine Ether efficiently on Windows 7 using the 10xx GPUs. The problem was fixed for the 16xx, 20xx, and 30xx. If you want to mine Ether with the 10xx, employ Windows 10 or Rave Os.

Ethereum Mining Overclocking on the Nvidia GeForce GTX 1060 (6GB), 1070, 1070Ti

These GPUs accept GDDR5 retention, so their overclocking algorithm is the same.

1. Turn on the mining software without overclocking. Offset raising memory clock little past little at +50 MHz intervals. Discover the clock value that makes the GPU commuter crash (reload), motility 50 MHz down to the stable area.
2. Beginning lowering PL little by little, by around 1%. The GPU starts consuming less ability and the temperature goes downwardly. At some point the speed will start falling. Terminate at 5% of the speed decrease.
3. Start raising the core clock little by lilliputian. Observe the clock value that makes the GPU commuter crash, move 25 MHz down to the stable area.

The speed lost at Footstep 2 must exist fully restored at present. If it's not fully restored, you could raise Power Limit by a bit, but in this case energy consumption would also go up.

Ethereum Mining on the Nvidia GeForce GTX 1080 and 1080Ti

The 1080 and 1080Ti feature high-timing fast GDDR5X memory that initially wasn't as adept at Ethereum mining as GDDR5. Nevertheless, after the release of ETHlargementPill-r2 that lowers timings for this type of retentivity, they started mining Ether quite successfully.

The pill makes memory less stable and lowers max overclocking potential. For the most early on GTX 1080 carte revisions (Rev.A) the pill is unstable even at standard clocks, so to ensure the GPU stability you lot have to lower the retentiveness clock.

If the mining software is still unstable after that, you should utilise the soft alternative to the pill for such GPUs. Information technology's the –mt parameter in t-rex that goes from 0 to 6. The higher y'all set this parameter, the more it lowers timings but also stability.

After you successfully activate the pill or employ the –mt parameter, follow the aforementioned overclocking process every bit with the 1060 and 1070.

Ethereum Mining on the Nvidia GeForce GTX 16xx and 20xx

These GPUs can easily place big volumes of data in the memory and accept powerful cores.

The overclocking algorithm is simple.

1. Lower PL to the min value.
2. Start raising retentivity clock niggling by little at +50 MHz intervals. Observe the clock value that makes the GPU driver crash, move l MHz downward to the stable area.
3. Check whether higher PL leads to a higher hash charge per unit.

If it does (which information technology does for some 2080 and 2080Ti models), discover the max hash rate you can obtain past raising PL. Do the post-obit steps next.

• First lowering PL little past little, past effectually 1%. The GPU starts consuming less power and the temperature goes downwardly. At some point the speed will start falling. End at 5% of the speed subtract.
• Start raising the cadre clock footling past little. Find the clock value that makes the GPU driver crash, move 25 MHz down to the stable area.

The speed lost at Step two must be fully restored now. If information technology'south not fully restored, you could raise the Power Limit past a flake, merely in this example free energy consumption would also become upward.

ETH Mining on the Nvidia GeForce RTX 30хх

The 3070, 3080 and 3090 are the trickiest Nvidia cards in terms of overclocking, so let'south get into detail. The 3060 and 3060Ti overclocking is the aforementioned as with the 20xx series.

Ethereum Mining on the Nvidia GeForce RTX 3070

When you are overclocking the 3070 and other older GPUs of the 30xx serial, information technology's important to understand what the card is missing. The graphics card normally gives out 60 MH/s, you tin can get 63-64 MH/s by overclocking. The card has a powerful core, which is quite useless for Ethereum mining that doesn't require more than 700-800 MHz. So make sure to limit your GPU appetite.

The 3070 is easy to overclock. The first step is to overclock the memory to the stable maximum. So lower PL.

1. Start raising memory clock little past niggling at +50 MHz intervals. Find the clock value that makes the GPU commuter crash, move l MHz down to the stable area. The constructive memory clock in MSI Afterburning must be 8100–8400 MHz.
2. Outset lowering PL by 1%. The GPU starts consuming less power and the temperature goes down. At some point the speed will beginning falling. Become back by a few percent.

At some point when you lower PL, the cadre clock may start fluctuating, going below one GHz from fourth dimension to time and so going back in a second. It ways that the graphics card doesn't have enough Power Limit.

This effect is called throttling. Information technology's important to annotation that t-male monarch and other mining programs may display a high hash rate, but in reality it is iv-5 MH/due south lower than the displayed value.

When the card heats and fans are overclocked, make certain to raise PL a picayune. Nvidia includes the fan ability consumption into PL, then the core may get-go lacking power.

The bottom line is that you shouldn't over-constrain PL. The 3070 normal consumption for mining is 130 W at the hash rate of 63 MH/s.

You will become the best result on Windows 7 past setting the core voltage at 713-725 mV and lowering the core clock. With the good retention you will become a hash rate of 64.6 MH/s at the consumption of 121 W. It'southward t-rex unadjusted for the devfee.

By using -forcePState:0,0 control in the Nvidia Inspector you can get 61 MH/southward at the consumption of 107 W, or 570 MH/s per kWh. In this example first y'all need to restore the operating mode after reloading, and simply then activate mining. Otherwise, the commuter will crash periodically. It makes no sense to save 10 W per GPU.

Ethereum Mining on the Nvidia GeForce RTX 3080

When you are overclocking the 3080 and other older GPUs of the 30xx series, it's important to empathize what the carte is missing. The 3080 cadre is excessively powerful for Ethereum mining, and then you should limit information technology as much equally you can first, without throttling. Then you can overclock the retentiveness.

Windows overclocking.

1. Bring the retentivity clock to minimum. Set the core voltage at 750 mV using MSI Afterburner, salvage, and cheque the retention clock. Information technology should be around 7500 MHz.
2. Start setting the voltage in the lower range (743 mV – 725 mV — 713 mV — 700 mV). Notice the value that brings the retentiveness clock down to 5000 MHz (P3 state), brand one step up from it. Brand sure that the retention clock is now above 7000 MHz.
3. Lower the core to the min value. Activate mining.
4. Start raising memory clock little by footling at +50 MHz intervals.

And so you have two options.

1. Notice the clock value that makes the GPU driver crash, move 50 MHz down to the stable area.
   And then y'all can raise the clock a little and cheque whether the hash charge per unit is growing. If it is, go on raising the clock until you lot accomplish the limit.
2. Detect the limit afterward which the core starts fluctuating and falling below 1 GHz. Nosotros have a GPU with a weak ability supply, so we stop here and relish the hash rate higher up 90 MH/s.

Ethereum Mining on the Nvidia GeForce RTX 3090

The 3090 overclocking is identical to the 3080. Just continue in mind that the 3090 acts equally the excessively overclocked 3080 with a weak ability supply.

AMD RX 5ххх and 6ххх Overclocking for Mining

Let'southward run into how to overclock AMD graphics cards from its new and quite effective series. Unlike Nvidia, these GPUs don't take special smart states at the BIOS level.

So Windows doesn't aid you get a better hash rate. Furthermore, information technology lowers stability. It's non surprising that most "blood-red" miners (AMD logo is blood-red) prefer more stable Linux-based solutions, like RaveOS.

Such systems make overclocking piece of cake.

1. Overclock the retentiveness to 900+ MHz.
2. Set the core at 1350-1375 MHz.
3. Lower the cadre voltage little by little at intervals of 5 until it remains stable. You can go as low as 800 mV for certain and you tin try going lower depending on your graphics card.
4. Lower the memory voltage. Yous can set 800 mV for certain, but if you go lower, make certain to bank check stability.
   As a outcome, you maximized your hash rate and minimized consumption.

The AMD RX 5600 user provided united states of america with overclocking instructions.

The core is from 1100 to 1200, the retentivity is from 950 – lower until the graphics bill of fare becomes stable that is, up to 900 at intervals of 5. Yous can try bringing the cadre and retentiveness voltage to 740. However, stability is important to me, and my setup had been working for 18 days without crashing.

Here are the results for the RX 5600.

As for the AMD RX 5700, you tin set the cadre at 1300-1325-1350-1375 and bring the memory to 930 and and then lower at intervals of 5. If they are not stable, go down to 900. The voltage is 780.

Here are the results for the RX 5700.

Nvidia Mining on Kawpow

Kawpow algorithm with RVN as the main cryptocurrency entered the mining industry with a blast. The Ravencoin hash rate tabular array below demonstrates the growth in popularity. The hash rate in the 2Miners pool has increased 5 times in a month.

At the same time RVN price increased by 500% in forty days. On February 20, 2021, it ready the tape of 28.5 cents.

The algorithm works even with 3GB GPUs, adjusts well (many GPUs that are problematic on other algorithms work well on kawpow), and speed correlates to GPU PL. Furthermore, RVN is featured on many major exchanges.

If you lot wait at all the factors, the algorithm comes second best in terms of prominence and profitability in GPU mining after Ethash.

Windows 10 requires GPUs with at to the lowest degree 4 GB of RAM. For Windows 7 and Rave Os iii GB of RAM is still enough.

GPU Overclocking for Kawpow

Setting up GPUs for Kawpow is quite easy.

1. First, we should place the max retentiveness clock at +25 MHz intervals. Find the clock value that makes the GPU commuter crash, move 50 MHz down to the stable area.
2. Discover the core voltage that will give you the desired GPU energy consumption. Lower voltage results in lower consumption, but also in lower max hash rate. Relationship is not proportional. When you lower the consumption by 25–35% from standard, the speed decreases only by 15–twenty%. This gives us a unique opportunity to schedule for GPUs to overclock automatically at the best time for multi-rate meters.
3. Find the max stable core clock (at +25 MHz intervals), motility 25 MHz down from it.

Fine tuning would give usa additional 2–half dozen% of hash charge per unit or 2–4% of energy efficiency. We volition not go into more detail in this article.

Energy Efficiency in Mining. Operating modes

Any GPU tin operate in power saving mode, but overclocking allows you to maximize hash rate. At the same time, energy efficiency suffers.

Not all rigs work well with whatsoever algorithm, so every expert user must test their GPU operation at maximum and minimum capacity and choose the optimal mode, considering operating temperature and electricity costs.

You can save the results as links to 2CryptoCalc that allows y'all in simply a few clicks to evaluate whether your algorithm is meliorate or worse than alternatives in terms of the current mining profitability specifically for your rigs.

Electricity costs and current turn a profit are crucial when you lot are choosing an algorithm and rig operating fashion.

Max Energy Efficiency and New Rigs

Sooner or afterwards, all miners terminate up estimating max hash rate per 1 kW of a rig power due to either electricity toll or the limit of "complimentary" power.

Hither are max hash rates adjusted for the dev fee per 1 kW of utility power with Platinum PSUs for the 10xx, 20xx and 30xx series.

* – The 30xx serial stats are up-to-engagement as of December 25, 2020.

As you can see the 20xx series has a marginal benefit per i kW ane.5x higher than the previous one. It's mainly due to the enhanced retentivity access algorithm. For algorithms that mostly utilize the GPU core the upshot is less impressive – 33%.

Free energy efficiency deteriorates with each new Ether epoch.

PS

This year nosotros expect a lot of new GPU releases. So the balance of power may modify with new GPUs and mining software entering the market. Who knows, we might fifty-fifty see new mining algorithms. The article is upward-to-appointment as of the showtime of March, 2021. We will update it as we go the new data.
