Ethereum mining best settings on NVIDIA GeForce GTX 1080
2021 has brought a number of late entries into cryptocurrency mining for Ethereum & Bitcoin. Currently, GPU’s are being scalped for ridiculous prices. Please know that big changes are coming in how Ethereum is mined which will eventually eliminate GPU mining completely. Also, EIP 1559 could reduce current mining fees by 40%! Buying a card at 3x MSRP is not a risk I would take! You cannot calculate a long-term ROI based on current mining revenues. You will still be able to mine other coins, however, know the risks of investing in new equipment.
If you have a gaming PC bought in the last couple of years like the OMEN by HP 880-120, it will have a graphic card capable of mining. I will go into all the details on how to get started with mining in this article, as well as how to optimize your settings to get the best hash rate out of your NVIDIA GeForce GTX 1080 graphics card. This will also work on the GTX 1080i and Titan XP but your overclock settings will vary. Please understand that overclocking your card can cause serious damage, so proceed at your own risk! These are settings that work on my gaming desktop with no issues. Click the hyperlinked words to download software.
First Step- You need a wallet in order to store your collected Ethereum. I suggest using Coinomi because they have an app for your phone and it is versatile. Download here. Your wallet address is in the app under the coin in the receive tab. Email it to yourself, you will be using it in the next step.
Second Step-
UPDATE: 11/2021– I am now using nbminer because it does not require the ETALargement pill to maximize your hash rate. I get about 33MHs. Also, I think I am getting more accepted shares per day! The –memory-tweak 4 replaces the ETALargement pill the –api 192.168.1.216:21302 is optional and just allows you to specify the API address and port for monitoring your miner! Only Download NBminer from the official website here- https://nbminer.
com/
You may need to run as administrator the first time you run it.
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100nbminer.exe --memory-tweak 4 -a ethash -o ethproxy+tcp://us1.ethermine.org:4444 -u WALLLETADDRESSGOESHERE.MACHINENAME --api 192.168.1.216:21302
or
nbminer.exe --memory-tweak 4 -a ethash -o ethproxy+tcp://us1.ethermine.org:4444 -u WALLLETADDRESSGOESHERE.MACHINENAME You can skip this part below if you use NBMINER!
SKIP THIS PART
You need Phoenix Miner 5.5c. You can download it from the official site here. Please note, this is a password-protected file that must be opened with a program like winrar. The password is phoenix! I suggest extracting to C:\Mining\Software\Ethereum\. Once you extract this, find the file called 5_Ethereum-ethermine.bat and edit it with notepad. Below are my settings that worked best. Note: you will need to add your wallet number, and you can also name the worker anything you want.
For example -worker NVIDIA could be -worker HPGaming. Replace C:\Mining\Software\Ethereum\ with the path to the file! Also, change the pool to match your location! My example is for USA East Coast.
Pool addresses:
Asia- asia1.ethermine.org
Europe- eu1.ethermine.org
USA east coast- us1.ethermine.org
USA west coast- us2.ethermine.org
Below is what you put in your .bat file. Bold can be customized as mentioned above.
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
start C:\Mining\Software\Ethereum\OhGodAnETHlargementPill-r2.exe -revA
C:\Mining\Software\Ethereum\PhoenixMiner.exe -pool us1.ethermine.org:4444 -wal YOURWALLETIDFROMSTEP1 -worker NVIDIA -epsw x -mode 1 -log 0 -mport 0 -etha 0 -ftime 55 -retrydelay 1 -tt 79 -tstop 89 -coin eth
pause
Third- You will need a script called ETALargement pill to maximize your hash rate & prevent crashes.
This only works on the NVIDIA 1080, 1080 Ti and Titan Xp! There are some altered versions floating around with malware, I downloaded mine here and verified the file size and md5 hash of the software. Put this file in the same path C:\Mining\Software\Ethereum\
The file size is 458,240 bytes & MD5 is 1351bf58a407fa5f89a6613e00a2e9df. On a side note, you can verify a file’s HASH by using hash generator 7.0. This must be left running or Phoenix will mining will have errors.
END OF SKIP
Fourth Step- In order for ETALargement or NBminer to keep the P0 Power state, you must Download NVidia Profile Inspector. You want to scroll down to #5 -Common and change Cuda force P2 State to off and click Apply! This step is vital.
Change CUDA- Force P2 State to off.
You can verify your GPU is in P0 Power state by creating a bat file or manually executing this from the command line:
cd C:\Program Files\NVIDIA Corporation\NVSMI\
nvidia-smi -q -d PERFORMANCE
PAUSE
Fifth Step Download MSI Afterburner.
This is where you will fine-tune your GPU after you start the C:\Mining\Software\Ethereum\5_Ethereum-ethermine.bat file mention above by watching the Eth Speed seen in the video below . Overclocking your GPU can damage or reduce the life, especially if you get carried away on the settings and use this at your own risk! The temperature should ideally never go over 70°C. There is no exact science on the settings because microchips vary in manufacturing. If you get a good one, many call it winning the silicon lottery! I spent a lot of time testing various settings. I was able to get 35.5 MH/s using Core Clock +225, Memory Clock +675, Power Limit 73 and fan speed automatic on an HP OMEN 880 gaming desktop. This can vary though! On redit, another user reported using Core Clock -50, Memory Clock +700, Power Limit 74 and reported 37 MH/s. When I set my power to 74, performance degraded, so you must try different settings to tweak your GPU. If you get errors when running the Phoenix 5_Ethereum-ethermine.
bat script, this means you need to try other settings. Monitor closely for stability before leaving unattended. When done testing, click the windows icon to apply settings at windows startup automatically! Share your final results in the comments below!
Optionally, if you wish to start your mining 5_Ethereum-ethermine.bat file when your computer starts, you will create a shortcut and copy it to the startup folder.
Right-click on 5_Ethereum-ethermine.bat and create a shortcut.
Right-click on the 5_Ethereum-ethermine.bat shortcut you just created, and select cut.
Go to the search the web and windows box (next to the windows startup icon) and type in run.
When the run window pops up type in shell:startup
Now you should be in the startup folder where you can add batch files.
Right-click and select paste or you can click the home tab and select paste.
Wait about two hours and you can check the results of your mining on ethermine.org by putting your wallet number in the address below: https://ethermine.org/miners/YOURWALLETIDFROMSTEP1/dashboard The payout is confusing, but in short, you get paid every couple of weeks after your total is over 0.01 which is only about 15-20 dollars worth of ETH. Some people think it needs to be 0.1 but that is only to get paid daily.
MSI GTX 1080 Gaming X Review, Overclocking, & Thermal Benchmarks | GamersNexus
How to Overclock the GTX 1080, Pascal GP104, & GTX 1070
From our 1070 review:
“Overclocking has changed with Pascal. It’s gotten more advanced – but not more complex. The core functions of overclocking remain the same; we’re still using manual stepping and sliders to achieve high, sustained overclocks, but a new auto OC tool (currently only with EVGA Precision) makes limit finding easier. In theory, anyway. We couldn’t get it to work with our GTX 1080, but it seems that EVGA Precision’s auto-OC (called “ScanOC”) is now functioning with the latest press drivers and installation package.
But we decided to keep going the manual route – it’s just better for testing.”
And from our 1080 review:
“GTX 1080 overclocking is revised heavily from previous generations. The GTX 1080 and GP104 move nVidia from GPU Boost 2.0 to GPU Boost 3.0. GPU Boost 3.0 and supporting applications from AIB partners will allow for frequency-voltage curve creation that fine-tunes voltages against various frequencies. Rather than functioning on a single slider for frequency, applications like Precision and Afterburner will now create a curve that fits your card’s particular silicon.
Anyone who’s overclocked knows that a high frequency may be sustainable in most games or for long stretches of time, but that some specific applications or use cases will crash the drivers resultant of the overclock. The obvious solution is to step-down the OC globally until something is stable across the board, but then we’re losing OC room in the use cases that didn’t originally trigger faults.
GPU Boost 3.
0 supports scanners, which figure out the optimal frequency for each individual voltage point. If a particular voltage point is less stable, the frequency offset can be adjusted by the tool or by manual control. In EVGA Precision, a ScanOC tool finds the optimal setup and provides a baseline that allows enthusiasts to further tune their setup. Vendors can determine parameters for voltage-frequency curve determination by the OC scanner.”

| 2050 | 90 | 5454 | 400 | 107 | 40 | P | P |
Through manual overclocking with Afterburner, we stepped completely through the MSI GTX 1080 Gaming X’s range and found that it settled firmly at 2050MHz core clock and 5454MHz memory clock, nearly an effective 11GHz.
The power target maxes out at 107% and vCore stops gaining at 1.062V.
Because we use real-world applications for our overclock validation, these numbers are representative of what you would see (on similar hardware, silicon lottery notwithstanding) in actual overclocking. Overclocks exceeding 2100MHz on Pascal seem to have issues validating in endurance tests (as we’ve shown) or with non-synthetic applications. It is easy to exceed 2100MHz with Furmark, for instance, as Furmark only loads the GPU in one very specific way – but fluctuating loads / demand of gaming will destabilize those higher OCs.

Overclocking of Nvidia video cards for mining on the example of GTX 1080Ti
No one mines on the basic settings of video cards, even beginners. Any miner very quickly comes to the question — and how to overclock video cards?
At the end of 2020, we published a detailed article about the basics of mining and overclocking video cards. It describes the features of working with different mining algorithms, and also has a lot of comments and screenshots. We advise you to take a look. nine0014
Unfortunately, there are very few sensible overclocking guides on the Internet, especially overclocking the latest green cards (Nvidia) with the ability to edit the frequency-voltage curve.
Correct mining is, first of all, rationality, rationality in everything — in the choice of equipment, premises, tariffs. Mining on an industrial scale does not happen on a free outlet, even where the payment is for a room, and not for electricity, there are still power limitations. nine0011
It is rational to get maximum return at minimum cost.
In this review, we will try to show what Nvidia GTX 1080 TI series video cards can give us with the right overclocking using the MSI ARMOR 1080 TI 11G video card as an example.
For overclocking in the Windows operating system, we need MSI AfterBurner version 4.3.0 or higher. To control the power consumption modes of the cards, we use the standard NVSMI utility from their developer.
The main algorithm for NVIDIA GTX 1080 TI cards is Equihash, but this technique works for all algorithms! nine0011
We will disperse the EQUIHASH mining card using the EWBF miner 0.3.4b

- 3 Frequencies and stresses
- 4 Age Video 9003 5 Downclock
- 6 Automatic switching PL
- 7 Conclusion
Basic overclocking tasks for video cards:
- Determine the maximum overclocking capabilities of the card.
nine0038
- Find the maximum and optimal energy efficiency ratio for this card.
- Learn how to set automatic mode change over time (for a multi-tariff meter).
Overclocking technique for Nvidia video cards
Enable core voltage monitoring in AfterBurner.
At 100% loading of cards (and equihash mining gives exactly constant 100%), the power consumption of the card depends on the voltage on the core.
It would be ideal to set the minimum voltage, but along with the voltage, the maximum acceleration frequency also drops significantly. nine0011
The dependence of the cutoff frequency on the core voltage for this series is a typical exponential dependence.
Up to a certain voltage limit, frequencies can be seriously increased with each step, but after a certain maximum frequency, further increase is almost useless.
We need to find a middle ground — when an increase in the output speed will be cost-effective in relation to the consumption of the card.
Of course, in conditions of super profitability (May-June 2017 and December-January 2017-2018), it is in principle unprofitable to limit the voltage greatly, but we are considering and developing systems that are planned to be used for months without switching. At the same time, a small lack of speed during the period of super profitability is more than compensated by serious savings during the period of medium and low profitability, lower energy bills, lower ventilation and cooling costs, noticeably higher density of installation of farms and long service life of video cards. nine0011
Frequency and voltage curve
When you select any video card, Afterburner allows you to set the overall overclocking for the core and memory. This is a rough path, but efficient enough for overclocking without taking energy efficiency into account. Also, this option is great for overclocking under the Dagger Hashimoto algorithm.
This rough method has a very big disadvantage when using cards in downclocking — the card can keep overclock +200 at PL=70%.
But do not keep it at 100%: in case of a pool freeze, the card stops counting hashes and slows down. After the resumption of receiving tasks, it counts the first seconds at higher core voltages of 100% — the driver may crash (especially true for mining via 3G / 4G or Wi-Fi). nine0011
For more precise tuning of green cards of the 10xx and higher series, the manufacturer gave access to a separate frequency editing for each core voltage point (and there are dozens of them).
Press Crtl+F, a curve opens, each point of which corresponds to a certain core voltage (in X) and the operating frequency specified for this voltage (in Y).
With a given PL (Power Limit — consumption limit), the card starts at 100% and immediately tries to meet the specified consumption, running up or down this curve. nine0011
An important feature of Pascal architecture cards is that having two adjacent points with the same frequency, the card will always choose a lower voltage and will not use other voltages (for all cards, the upper horizontal frequency plateau determines the card’s reluctance to go higher in voltage and frequency).
This way you can create a horizontal plateau of the same frequencies (in the screenshot above, all points from 925 millivolts are set to a frequency of 1911 MHz).
Let’s remember this important fact, we will need it later for selecting modes. Let’s move on to overclocking from scratch. nine0011
Video card overclocking
Unlike core frequencies and voltages, the memory frequency is fixed and is set immediately. Therefore, before overclocking the core, we go through different memory frequencies, raising them by 25 MHz and finding the point of maximum stability of memory operation (before the driver crashes).
In our case, we (to save time) set the approximate maximum for most 1080Ti. This frequency is 5800 MHz, almost all cards take it, some copies work at 6000, which by itself will slightly increase the hashing speed). nine0011
If we just limit the PL (power level), we get something like this:
IMPORTANT! When testing in each miner, we launch one card, in this case, when the driver crashes, the rest of the cards will remain working (the load monitoring in watts will just crash).
We will be interested in what maximum frequency the card will give at each voltage.
This is a chore, requiring several hours of intensive sitting and picking.
Often the card can behave illogically, taking one frequency at 900mV, and a little higher only at 943mV, be patient.
IMPORTANT! When the driver crashes, all points and PL return to their original state, we will lose progress, therefore, if it fails, we change 1 point and save without switching the map to AB (we will save the setting if we switch the map — all over again).
After an overclocking failure, the miner gives an error with different codes Thread existed with code: 46, 17, 53, etc. nine0002
Unfortunately, AfterBurner does not allow editing points below 800 mV (although you can go there by reducing the PL even lower). This does not interfere much, because, as we see, the optimal ratio is higher.
In our opinion, it is optimal to have a speed of 690-700 sols at 190 watts.
Yes, an increase of 60 watts will add 70 sols (60W for 70 sols — 2 times worse than mining on old AMD 7th generation cards), is this a logical ratio?
IMPORTANT! nine0006 All other points from the found ones are set equal in frequencies to the found ones.
We get STEPS:
We can already walk on these steps manually, decreasing or increasing the power limit (PL) parameter.
It is interesting to do this in automatic mode, more on that below.
IMPORTANT! Often, Tishka (as the very expensive and powerful 1080ti is affectionately called) does not immediately save the points (especially under load) or changes them according to its internal algorithm. Because of this, you have to expose them several times. nine0011
To check the correctness of saving the points, switch to another map, and then return and check the points of the curve.
Auto-switching PL
Use the NVSMI utility from the card developer to control and monitor the power limit at your discretion.
You can download it here — https://yadi.sk/d/bQ5uqzm13RV5hR
We put this folder, for example, in «c:\Programs\» and when using executable batch files we get information about the cards and manage them. nine0011
Changing power is very easy. For example, to set the 250 W limit for card #0, we need a file with the content:
C:\Programs\NVSMI\nvidia-smi.exe -i 0 -pl 250
Result:
But for first we need the file list.bat
Its content is:
nvidia-smi.exe -L
pause
It lists the cards in the system. Now we can match the names of the cards to their numbers. nine0011
But we have the same cards! What to do?
Use the consumption mapping executable (example s_power_0.bat) with the following content:
nvidia-smi -i 0 --loop-ms=1000 --format=csv,noheader --query-gpu=power.draw
It displays the current consumption of the card with the specified number, and so on for any card.
By starting mining on only one card, we can easily understand what it is by number.
Having decided on the numbering of the card, we create common files for switching power on all cards at once. nine0011
In our case, we have created 3 files (hard, normal, soft) that can be activated for the night rate, for the semi peak rate and for the peak rate respectively.
IMPORTANT! Changing PL is possible only when the file is executed as an administrator, so each file contains full paths to the NVSMI utility.
Go to Start->Accessories->System Tools->Task Scheduler
In the scheduler, set the HARD mode to start after 23h, SOFT mode at 7h and 17h, NOrmal mode at 10h and 21h. This corresponds to the three-tariff switching time in Moscow, which will allow you not to waste electricity during rush hour and get the maximum in a cheap nightly tariff. nine0011
Conclusion
Mode switching is rarely used, but increasing the frequencies at the most stable point (usually 900 mV or 950 MV) along with lowering the Power Limit will allow you to get maximum energy efficiency and minimum temperature of your cards.
Do not burn your cards in vain and they will thank you for many years of stable service.

Ethereum mining on 1080/1080 Ti in 2021: income, tuning and overclocking
When a miner has enough money for a new video card, this is the farm’s payback. Before buying and starting mining, you should figure out the math: the cost of investments, the expected profit and the payback period. Indeed, in recent years, due to the growth of the entire crypto market, interest in mining and mining equipment has increased significantly. Accordingly, this created a shortage of top-end graphics cards for mining, and their value flew “to the moon”, just like Web 3.0 tokens, which are now gaining great popularity. Today we will look at one of the most popular mining cards — Nvidia GeForce GTX 1080 and its modification GTX 1080 Ti .
1080 or 1080 TI — is the prefix in the name worth it?
Video cards have a big difference in performance and specifications.
Here is a comparison table of all cards of the tenth series in terms of the amount of memory, CUDA cores, manufacturing process and the number of transistors.
| 1050 Ti | 1060 (6gb) | 1070 | 1080 | 1080 Ti | |
| Video processor | GP107 | GP106 | GP104 | GP104 | GP102 |
| Process: | 14 nm. | 16 nm. | 16 nm. | 16 nm. | 16 nm. |

| Stock to boost: | 1290 — 1392 | 1506 — 1708 | 1506 — 1683 | 1607 — 1732 | 1480 — 1582 |
| TMU: | 48 | 80 | 120 | 160 | 224 |
| CUDA Core | 768 | 1280 | 1920 | 3584 | |
| Video memory: | GDDR5 | GDDR5 | GDDR5X (since 2018) | GDDR5X (since 2016) | GDDR5X (since 2017) |
| Memory capacity: | 4 GB. |
6 GB. | 8 GB. | 8 GB | 11 GB |
| Memory bandwidth: | 112 Gb/s | 192 Gb/s | 256 Gb/s | 320 Gb/s | 484 Gb/s |
| VRAM channel bus: | 128-bit | 192-bit | 256-bit | 256-bit | 352-bit |
| Eff. memory frequency: | 7 GHz. | 8 GHz. | 8 GHz. | 10 GHz. | 11 GHz. |
| Connectors aux. supply: | — | 6 pin | 8 pin | 6+8 pin | 6+8 pin |
| Suitable for: | 75 watts. | 120 Watt | 150 Watt | 180 Watt | 250 Watt |
Compared by the number of transistors, the 1080 Ti is definitely a success. The width of the memory channel has also increased compared to 1080 — up to 352-bit, due to which the throughput of the Nvidia card has risen to 352 GB / s.
The first card to use GDDR5X was the 1080, which Nvidia released on May 6, 2016. Since 2017, GDDR5X has been used in 1080 Ti. Models before the year of manufacture with GDDR5X use regular GDDR5, so be careful when buying cards from your hands. nine0011
Why it’s important to get GDDR5X cards
GDDR5X memory cards support pills to increase the hashrate when mining Ethereum, which can raise 37 MH / s to 50+ MH / s, which is almost like buying a new video card. A nice addition is that the GDDR5X memory frequency is 11 GHz for 1080 Ti and non-Ti.
Budget video cards from Nvidia for mining Ethereum
The budget segment can be considered 1070 — the golden mean between performance and price, starting at $630 per unit. The segment that is more profitable from the mining side starts at 1080. 1060 with 6 GB of memory is suitable for a completely “on-the-knee” crypto-farm. nine0011
Using the GeForce 1050 Ti is justified only when mining cryptocurrencies in zombie mode, when the card stores part of the dag file in the computer’s RAM.
Cards of the 50th series are well suited for a dirt-cheap altcoin mining farm, it is not recommended to mine Ethereum on them. Do not expect profit from the mud farm — this is an activity with a negative KDP, except that there were 5 shareware cards on the mezzanine.
Comparison of profitability and cost of video cards for mining Ethereum and altcoins
| The cost of video cards in USD | 1050 Ti | 1060 (6 Gb) | 1070 | 1070 Ti | 1660 Ti | 1080 | 1080 Ti |
| New card price | 250 — 290 | 240 — 280 | 630 — 750 | 700 — 800+ | 660 — 720 | 610 — 650 | 1100 — 1200 |

Payback 1070, 1080, 1080 Ti
Given the profitability and price range, the 1070 and 1070 Ti line of cards perform well, almost close to the 1660 Ti in terms of daily profitability. nine0011
Conventionally, the payback of one GeForce 1080 Ti at a price of $900 with a daily income of $5.28 should be expected in 170 days.
The figures you will receive are indicative, but they will allow you to calculate the approximate payback period for the entire farm or one video card.
The 1080/1080 Ti
hashrate comparison table shows an increase of 16 to 27% over its predecessor.
Eg. on the KawPow algorithm, the increase was 18 Mh/s when moving from 1080 to 1080 Ti, which is equivalent to a double increase. nine0011

The cost of the GeForce 1080 Ti ranges from $760 to $1000. The tenth generation of video cards is profitable in itself. The 1080 Ti has a memory bandwidth of 11 Gb/s, versus 7 Gb/s for the 980 Ti.
Which cryptocurrencies to mine on 1080/1080 Ti
The card itself is a high-end solution from Nvidia, in terms of performance it is next to AMD’s RX Vega 64 and RTX 2060. For its price, it is quite an acceptable purchase for a farm. Miners note that this card is prone to overheating, it is recommended to take models with three fans. nine0011
Tentatively, the card will be good at mining ETC, Grin and ETH on the Ethash algorithm. It is recommended to mine Ether or Classical Etherium on it.

What to mine on 1080 Ti
The card appeared in 2017 and cost at that time 700 dollars, in the CIS the price could reach up to 80.
As of early 2021, the 1080 Ti can be found for $350 on the used market and up to $520 for a new card with a warranty. nine0011
Thanks to 11 GB of memory, the card is able to mine any cryptocurrency, including the Ethash algorithm.
1080 Ti mining profitability calculator for different cryptocurrencies
Given the results of the video card profitability calculator, the 1080 Ti becomes the most profitable option out of a pair of cards, but the non-Ti version is not far behind. Both cards are capable of issuing enough hashrate to get one dollar a day, excluding commissions. nine0011
As with all good things, there must be a lot of cards for profitable mining. A rough estimate shows that in 365 days the 1080 Ti will give out $511 from Ether alone, enough to buy a second card. Further — increase in income with each purchased card.
One way or another, income from one video card will not bring golden mountains, but you can save up for a second card in a year.
The first year the crypto-farm reaches payback, in the second year it starts to make a profit. To reduce risks, we recommend budgeting for electricity or worrying about buying solar panels, laying a power network and batteries. nine0011
Power and PSU issue when assembling a farm
When buying video cards, you should consider the cost of assembling the cooling and the system as a whole. It is recommended to use aluminum bars as a supporting frame for the video card in order to avoid fire.
When assembling, miners are guided by the use of two power supplies for a farm of 6 video cards with a TDP above 150 to ensure a stable power supply to the cards.
The use of multiple power supplies is necessary when it comes to creating a large farm, a large farm is considered to be 4 cards or more. nine0011
Crypto farms with less than 4 cards are home mining.
A second power supply may be needed to power a farm with more than 6 cards.
This requirement has a simple reason: the card must receive stable power. If the power supply unit cannot supply the required number of watts via the 12 volt line, add. graphics card, then you will start to lose money due to hashrate drawdown
| Power supplies | 1 PSU (600 W) | 2 PSU (1000 W) | 3 PSU (1000 W) | ||||
| 1050 Ti | 1060 (6 Gb) | 1660 Ti | 1070 | 1070 Ti | 1080 | 1080 Ti | |
| TDP | 75 | 120 | 120 | 150 | 180 | 180 | 250 |
| Consumption (in W) | Number of maps and rivers. qty. BP |
||||||
| 2 cards | 150 | 240 | 240 | 300 | 360 | 360 | 500 |
| 4 cards | 300 | 480 | 480 | 600 | 720 | 720 | 1000 |
| 6 card | 450 | 720 | 720 | 900 | 1080 | 1080 | 1500 |
| 8 cards | 600 | 960 | 960 | 1200 | 1440 | 1440 | 2000 |
| For 10+ cards | 750 | 1200 | 1200 | 1500 | 1800 | 1800 | 2500 |
Do not forget about the load — mining is always work for wear at 100% performance, therefore the card will be at the peak of its activity all the time.
For example, powering 8 video cards from one power supply is a huge risk, the PSU may not cope with the load, burn out and take the entire farm with it to Valhalla. nine0011
Power for a farm body kit usually fits in 50 — 75 watts, this is a processor, RAM and a motherboard. If you take a CPU with a TDP of 35 watts, then the load can be reduced to 45 watts.
The requirement for BP is determined by the number of cards and their nominal TDP. When buying a PSU, several factors should be taken into account, the first is that the PSU needs a new one and it must have a power reserve. For example, a 600 W power supply will not be able to pull out a farm with 8 cards where each TDP has 75 watts, even if they nominally fit into the power consumption. nine0011
Overclocking and downvolting for 1080 Ti
During overclocking, only you are responsible for the results.
No one but yourself is responsible for the burned card.
You cannot return the card under warranty or receive service after overclocking.
There are two different definitions of «overclocking»
The first type: overclocking is for games — a maximum of 12 hours of load, work at near-limit indicators, video card consumption does not bother anyone. nine0011
Not suitable:
Second: overclocking is for mining — increasing the memory and video core frequencies, reducing the consumption of the video card in millivolts for stable operation 24/7 and electricity costs.
Suitable:
Downvolting is overclocking, but when the voltage on the memory elements and the GPU unit decreases and the frequencies increase. The purpose of downvolting is to find the golden seridine between consumption and performance.
How to overclock 1080 Ti for mining Ethereum
Download MSI Afterburner, install, unpack and drive the card in three necks.
To check if something falls off, download FurMark.
All experiments — with an excel file and on a motherboard separate from the farm. Don’t play with money.
Overclocking algorithm for GTX 1080 TI and GeForce 1080
Overclocking via MSI is as easy as a fork:
- Create an Excel spreadsheet or Google spreadsheet with two columns «Frequency» and «Temperature». nine0038
- Raise the memory frequency by 100
- Write to table
- Turn on FurMark, put the card for one hour in Stress-test mode
- Observe the image, see if there are any defects
- Record the average temperature of the card during the test in the table
- Repeat steps 2 to 5 until artifacts and image defects begin to fall out
- If the video card does not start, then try to raise the Power Limit, but as in the comic above, it may bake with a crust. nine0038
The algorithm for overclocking 1080 and 1080 Ti on the core is similar — increase by 10, turn on the stress test, fix the values in the table.
Overclocking algorithm after the appearance of artifacts
- Look at your table, choose those modes that give the least temperature and the highest memory frequency;
- Substitute the obtained values in MSI Afterburner;
- Turn on the stress test for a day and check if the card will survive; nine0038
- If after 24 hours the card is alive, there are no artifacts and the temperature has not exceeded 80 degrees — congratulations, you have overclocked the memory subsystem correctly
Optimal overclocking for mining for 1080 Ti
The following parameters are recommended for optimal tuning of 1080 Ti:
- Core Clock — add 100
- Memory Clock — add 700
- Power Limit — set to 55%
- Temp Limit — set to 69
nine0051
These figures were obtained by the sweat and blood of hundreds of miners and are suitable for the first farm.
Raising the 1080 and 1080 Ti hashrate with
tablets On March 1, 2017, Nvidia released the 1080 Ti card — it was fire, it was VR, it was GDDR5X.
This “X” prefix at the end of the memory name makes people a 40% increase in profitability compared to conventional cards.
The new generation of memory changed the scales in mining — at first it was impossible to get profit on the cards due to the inability of the algorithms to work with memory. Two years after the release, the mining community released the OhGodAnETHLargementPill software and mining became more profitable. nine0011
Tablet for increasing the hashrate on the GeForce 1080 and GTX 1080 Ti
Setup begins with downloading the tablet from Github. Linux version.
If you speak English, then use the public prescription for pills to increase the hash rate.
In a simple way:
Download the .exe file from github, unpack and run the utility with the tablet icon. After that, the program will feed tablets to increase the hash rate to video cards and you can mine. nine0011
What to choose for mining — 2080 Ti or 1080 Ti
Mining on 1080 Ti will be relevant for a long time, until the release of another card with 11 GB and support for GDDR5X, which can be found and bought for 450 — 500 dollars.
When mining ETC on 1080 Ti for $450, you can reach payback in 285 days or 8 months.
Simple calculation — the average 2080 Ti costs 1100 — 1000 dollars. In November 2020, its profitability was 2.03 USD when mining ETC, which gives a payback period of 542 days, which is approximately 16.5 months. nine0011
| 2080 Ti | 1080 Ti | |
| Price in USD | 1100 | 450 |
| Hashrate | 57 MH/s | 48 MH/s |
| Hashrate after tablet | Tablets no | 54 MH/s |
| ETC profit per day | 2.03 | 1.58 |
| Monthly profit | 59 USD | 56 USD |
| Days to payback | 542 | 285 |
As you can see from the graph, the numbers are not in favor of the 2080 Ti.
