How to increase hashrate: Overclocking | Unlock LHR (Best) GMiner 2.69 (Mining)

How to increase hashrate: Overclocking |unlock LHR (Best) GMiner 2.69 (Mining):  How best to mine on LHR video cards – Nvidia video cards are currently not in great demand from miners, since compared to AMD GPUs, they are much less powerful. Accordingly, mining on these video adapters is much more expensive. For example, the most powerful chipsets from Nvidia deliver about 150 KH / s, while AMD boasts 1500 KH / s.

True, Nvidia has a top model Tesla S2070, which gives 700 hash, but its cost makes many miners abandon the idea of ​​mining on it. Since Nvidia cards are not particularly profitable, the only way to mine a decent amount of crypto coins on them is to organize a mining farm from inexpensive but relatively effective models.

What does a mining farm consist of?

In fact, the farm consists of the same components as a classic PC, but with some differences:

  • The motherboard should be one of the top ones, and have at least 4 PCI slots for video adapters.
  • A processor is not really needed for crypto mining on a video card, so the cheapest of all compatible with the selected video cards is usually chosen.
  • In fact, there is only one requirement for DDR RAM: 4 GB or more. Otherwise, RAM can be the cheapest and simplest, since it does not participate in the mining process in any way.
  • The hard drive doesn’t matter either. In fact, it is only needed to store wallets and install the operating system, so instead of a hard drive, even a flash drive will be enough.
  • The power supply is one of the most important elements of the system; you need to choose it carefully and carefully. The main characteristic of a power supply unit is power, and you need to select it with a play of 150-200 W, not forgetting that power is consumed not only by the video card, but also by other elements of the system.
  • The video card directly calculates the hash functions of cryptocurrency blocks. This is the most expensive and basic component of the farm, so you will have to choose it carefully.
  • The cooling system is required to remove the heated air from the video adapters. In this case, the distance between graphic adapters must be at least 8 centimeters. In addition to conventional cooling with the help of fans, water CO can be organized, it is more efficient, but technically more problematic. Of the unusual systems for reducing the level of heating, oil can be distinguished, when all equipment is in a tank with technical oil, and some manage to use vegetable oil for these purposes.

Video adapter overclocking

As mentioned above, Nvidia video cards are low power at a rather high cost. Therefore, the only way to “squeeze” decent performance out of these chips is overclocking (overclocking). At the same time, for each card, the most suitable parameters of frequency and graphics core and memory are selected individually. These characteristics will affect both the mining efficiency and the stability of the entire system. It should also be remembered that overclocking increases the temperature of the equipment and increases power consumption. The more you overclock the video card, the more powerful CO will be required.

Compatibility

If the farm consists of several video cards of different models, then conflicts may appear during setup and overclocking, which will lead to a drop in mining speed and the performance of the entire system. In addition, the combination of the selected hardware affects the hash rate. If you choose the right components (motherboard and RAM), you can increase the mining speed. Since there are essentially no standardized solutions in mining, the same values ​​of video cards often become ineffective when installed in a different configuration.

Features of the organization of a mining farm

When creating a farm, you need to do some serious calculations in order to choose the most profitable option. It is necessary to calculate what all the components will cost, and to select them in the ideal ratio of profitability to energy consumption. You will also have to calculate the electrical power consumed by the entire farm, and calculate what the electricity costs per day will be. After all the calculations, a conclusion should be made about the payback and timing.

It all looks rather complicated, but there is good news: there are a huge number of online calculators on the Internet that allow you to calculate the profitability of a mining farm and other characteristics based on given data. The most advanced calculators take into account changes in the rate of the mined cryptocurrency in real time and constantly adjust their forecast accordingly.

What are the alternatives?

If you want to start steadily and start mining cryptocurrency without unnecessary stress, then perhaps you should use the services of cloud services? They work by analogy with cloud hosting or file storage: you just rent a remote service, use the facilities and get your profit. In addition, you get the opportunity to earn that currency, which is simply impossible to extract at home:

What are LHR video cards and how did they come about

For five months in a row, many GPU miners have been discussing the relatively recent term “LHR”. Active discussion in the professional environment began in May 2021 after the publication on the NVIDIA blog of an article titled “A Further Step to Getting GeForce Cards into the Hands of Gamers” available to gamers. “

Article on the Nvidia website

The full text of the article can be found here.

The article talks about reducing the hash rate on the Ethash algorithm for recently produced GeForce RTX 3080, 3070 and 3060 Ti video cards, so that they are less desirable for miners. These cards go on sale at the end of May 2021. NVIDIA and its partners label cards with the Lite Hash Rate or LHR identifier.

We will remind, a little earlier – namely in February 2021 – NVIDIA has already announced Halving Hash Rate for GeForce RTX 3060 video cards. The corresponding article is also posted on the blog on the NVIDIA website.

At the end of May 2021, NVIDIA announced the GeForce RTX 3080 Ti and GeForce RTX 3070 Ti video cards. The news about it was published here.

And although it was not officially announced about the presence of “LHR” in these video cards, according to unofficial information that appeared on the Internet even before the announcement, they also had a reduced hash rate on the Ethash algorithm. After the arrival of the GeForce RTX 3080 Ti and GeForce RTX 3070 Ti on sale and conducting tests, the information on the availability of “LHR” was confirmed.

Overclocking video cards to increase the hash rate when mining

Improving the performance of GPU cards for mining is an integral part of setting up a farm. Overclocking can be done using special programs running from the operating system, for this we recommend MSI Afterburner. Also, overclocking a video card can be achieved by flashing the BIOS.

We tell you in detail about all overclocking options here, there are also video instructions for AMD and Nvidia cards (the principle of overclocking is slightly different).

Our website also provides detailed reviews of the most popular GPUs for mining cryptocurrency in 2021:

What was the mining experiment conducted on: a description of the test bench.

Next, we conducted preliminary testing to assess the potential hash rate and the impact of LHR.

The composition of the test bench is as follows:

  • Motherboard: B85S2BIOSTAR Hi-Fi B85S2
  • CPU: Intel Pentium G3220
  • Memory: DDR3 SDRAM Kingston 4Gb
  • HDD: Seagate Barracuda 7200.12 160Gb
  • PSU: EVGA 1000 GQ 80+ GOLD 1000W
  • GPU: EVGA GeForce RTX 3080 Ti FTW3 ULTRA GAMING (1800 MHz Boost Clock, Memory Clock 19000 MHz (effective), TPD: 350 Watts)
  • Two video cards are connected to the motherboard, each via a PCI-E X16-X1 riser. OS: Windows 10
  • Nvidia drivers: 471.68/li>
  • Overclocking: MSI Afterburner 4.6.4 Beta 3
  • Monitoring: GPU-Z

Testing was carried out in a room with an ambient temperature of + 15 ° C.

The potential hashrate for the RTX 3080 Ti on Ethash and Etchash algorithms is estimated using PhoenixMiner. Let’s start the miner on our RIG with the following video card settings: PL (%): 70, CC (MHz): +0, MC (MHz): +1000

Immediately after the start, the miner shows the speed on the Ethash algorithm ≈116Mh / s, but after two minutes of operation it stabilizes at ≈64Mh / s.

Thus, we estimated the potential (without LHR blocking) speed on the Ethash and Etchash algorithms, and also made sure that blocking reduces the hash rate by ≈45%.

Special graphics cards for mining from Nvidia

Nvidia has prepared 2 graphics adapters that have been specifically designed for cryptocurrency mining. Both cards are based on existing Pascal chips, but have been modified for more efficient and efficient mining on Nvidia GTX chips. These graphics cards with GP104-100 and GP106-100 chips are provided by Nvidia Authorized Partners.

It is worth noting that the warranty for these video cards is only 3 months . The launch of Nvidia GTX GPUs for mining is expected in mid-June, but the timing may vary from vendor to vendor. On the P104-100 graphics chip, the performance / watt is claimed to increase 30% over the GTX 1060 3GB. And the P106-100 chip gives an increase of 10% in comparison with the same video card. Both video cards are produced without video interfaces.

The Nvidia P104-100 graphics card uses the same design as the Nvidia GeForce GTX 1080. But it provides much more performance per watt of consumed power, as the adapter is specially modified for mining with Nvidia GTX. Cards from different manufacturers come with different chip frequencies, while this base model runs at a base frequency of 1607 MHz. The overclocking frequency is 1733 MHz with 10 GB / s GDDR5X memory bandwidth and 256-bit bus width.

Power is supplied via a single 8-pin connector, and the power consumption is approximately 180W. The base model of the graphics adapter is slated for shipping at a price of $ 350, while the model from the manufacturer Inno3D is announced at a price of $ 370 – Inno3D P6D-N104-1SDN P104-100 Twin X2 8GB GDDR5X. These prices are significantly less than their in-game counterparts ($ 499).

The claimed mining performance on the Nvidia GTX P104-100 will be about 60 MH / s, but this performance will be achieved only after updating the adapter BIOS to the new firmware.

The Nvidia P106-100 model uses the same design as the Nvidia GeForce GTX 1060. This made it possible to configure the graphics adapter for mining with Nvidia GTX much more efficiently. The adapter operates at a base frequency of 1506 MHz, a turbo frequency of 1708 MHz, and a memory bandwidth of 8 GB / s GDDR5 with a 192-bit bus. Power will be supplied through the 6-pin connector and the power consumption will be 120W.

The base model in the US will be priced at $ 200, which is $ 49 less than the GeForce GTX 1060 6GB gaming counterpart. Here is the price of a specific Inno3D adapter (N5G-N106-4SDN P106-100 Twin X2 6GB GDDR5) – $ 235.

Released in October 2021, the Quadro GP100 16 Gb video card continued the line of the Quadro Nvidia family, becoming the first model in which the manufacturer combined the GP100 chip with HBM2 memory. And if the first GPUs GP100, built on the Pascal architecture in combination with the high-speed HBM memory of the second generation, were focused on the server segment, the company presented a new product containing 16 GB of memory and a PCI-Express interface in the consumer category in March 2021.

Specifications PNY Quadro GP100 16 Gb

The graphics card is based on the GP100 core containing 3580 FP32 / 1792 FP64 CUDA microprocessors. A distinctive feature of the Pny Quadro Gp100 16 Gb is the combination of a high-speed interface

Standardized in 2021 as JESD235a second generation memory with high bandwidth HBM2 (High Bandw> allowing 2 times the standard 16 MB memory capacity.

Experienced miners note a decrease in the performance of HBM2 memory in crypto mining when the temperature rises above 65 degrees. This is due to the adjustment of the thermal protection algorithm of microcircuits to increase delays with increasing memory temperature, which reduces the operating speed even while maintaining the same frequency.

The dual-slot card reaches 267mm in length and connects via PCI-Express 3.0 x16 via one 6-pin and one 8-pin cable, delivering 235W of power. the cooling system is represented by one centrifugal turbofan.

The GPU provides over 20 teraflops of 16-bit floating point computing. FP32 single precision performance is 10 teraflops. The graphics accelerator supports technologies: Nvidia SLI, Quadro Sync, Quadro Mosaic, Quadro Digital Video Pipeline, DirectCompute, OpenCL, Nvidia GPUDirect.

Like the entire Nv range>

The introduction of Pascal architecture into graphics accelerators was a breakthrough for all product classes. Due to the transition to the 16 nm process, there has been an increase in computing power by adding additional CUDA cores, clock frequencies have seriously increased. The use of GDDR5 with 16n prefetch allowed to increase the memory bandwidth. The result of this innovation is performance that significantly surpasses previous models.

The Pny Quadro Gp100 16 Gb model is focused on meeting the needs of designers, rendering, multimedia processing and scientific computing in the workstation segment. The card is equipped with four DisplayPort outputs and allows you to connect up to 4 5K displays with a resolution of 5.120 x 2.880 pixels at 60 Hz or 4 4K displays with a 120 Hz refresh rate. The accelerator also supports 10-bit color output.

The video card comes in a set, supplemented with accompanying documentation, DVI-D-SUB adapters, 8 pin to 2 x 6 pin, DisplayPort-DVI, 1 x Stereo Connector Bracket.

PNY Quadro GP100 16 Gb video card in mining

The cost of the Pny Quadro Gp100 16 Gb accelerator in 2021 is about 550 thousand rubles, which makes the card unprofitable for crypto mining. Meanwhile, stock mining hash rates show 42.6 MH / s for Ethereum, 1.58 Gh / s for Siacoin, 670 H / s for Monero, 409 Sol / s for Zcash. In Boost mode, the card produces + 100 / + 130 Mh / s.

It is obvious that a professional accelerator is focused on industrial applications, scientific and commercial development. Mining with Pny Quadro Gp100 16 Gb is interesting, rather, from an experimental point of view. Building mining farms based on the card is also extremely inefficient, primarily due to the high price. More justified in this regard would be buying a GTX 1080ti.

Comparison of Nvidia graphics cards As we wrote below, Nvidia adapters are considered very unprofitable for mining cryptocurrencies, and AMD cards practically ousted them from the market. Nvidia for mining is bought now either by beginners who just want to indulge in crypto mining at low speeds, or by those who are well versed in overclocking and know how to compose a mining farm from numerous video cards of different configurations

Below we provide a summary table with the characteristics of video cards from this manufacturer, sorted by power for convenience. Notes to the table: C – video processor frequency, M-memory frequency, V-voltage, W-power consumption. Up to 100 kHash / sec As you can see, the GTX 9800 is a very weak video card in terms of mining – only 2 kHash / sec.

Such indicators cannot even be taken seriously. The most powerful in this weight class are the GTX 275, 460 and 650. 100-200 kHash / sec The most profitable series can be called 560, 660 and 670. Tesla K40c model with 188 kHash / sec and 732 MHz video processor frequency can also be of interest. 200-500 kHash / sec Of this table, the most interesting are the various modifications of the GTX Titan and 780.

The most powerful in terms of kHash is the Nvidia Quadro K6000 video card with 485 kilohash per second. If you can boast of a computer with a good graphics card, then you can start mining bitcoins right now. However, in order to increase profits and do it professionally, we recommend purchasing several video cards (optimally from 4 to 6) and building your own farm for mining cryptocurrency.

By installing several video adapters, you can increase the level of computer performance, which will count much faster. it is video cards that provide all the computing power for mining (for most algorithms). Note that, taking into account the current prices for video cards, cloud GPU mining has become more profitable in 2021, which is more profitable than buying your own equipment, is much more flexible in the amount of investment and does not require maintenance of your farms. We made a detailed review about cloud mining of cryptocurrency with a rating of the best services based on the results of the last few years. Material navigation:

Testing GMiner in mining

GMiner was created by a Russian group of specialists in the field of high performance computing and cryptography. The first version of GMiner was released on September 21, 2021, since then it has been actively developing and supporting the most popular algorithms like Ethash, ProgPoW, KAWPOW, Equihash, CuckooCycle. The miner is focused on NVIDIA and AMD platforms.

Miner developers keep in touch with users on many popular resources and social networks.

Official website: https://gminer.pro Github: https://github.com/develsoftware/GMinerRelease BitcoinTalk: https://bitcointalk.org/index.php?topic=5034735.0

The maximum possible hash rate, taking into account the LHR blocking for the RTX 3080 Ti on the Ethash algorithm, is estimated using GMiner 2.62. Let’s start the miner on our RIG with the following video card settings: PL (%): 55, CC (MHz): +0, MC (MHz): +1300.

The miner shows the speed on the Ethash algorithm ≈66Mh / s. Please note that the Memory Controller Load, GPU Load and Board Power Draw graphics are stable, without significant “jumps”.

Let’s start the miner with the following video card settings: PL (%): 55, CC (MHz): +0, MC (MHz): +1000

Thus, we estimated the speed on one of the versions of the miner, which did not include the ability to unlock LHR, and also made sure that the hash rate of ≈64Mh / s – ≈66Mh / s with blocking.

How unlock LHR works with GMiner 2.67beta

On September 11, 2021, the development team announced GMiner 2.67beta. The peculiarities of this version are partial unlocking of LHR and new miner parameters —lhr 1, —lhr_tune1, —lhr_tune2.

You can download the miner and read about the release features here.

Let’s start the miner on our RIG with the following video card settings: PL (%): 70, CC (MHz): +0, MC (MHz): +1000.

Bat-file: miner.exe -a ethash —server eth.2miners.com:2020 -u WALLET_ADDRESS.RIG_3080ti -t 70 —log_newjob 0 pause

Immediately after the start, the miner shows the speed on the Ethash algorithm ≈68Mh / s – ≈85Mh / s, and after three minutes of operation it stabilizes at ≈78Mh / s. Please note that Memory Controller Load, GPU Load and Board Power Draw charts (like other Power charts) are unstable, with significant jumps.

To check the stability, we left the miner working for several hours, and after three hours a lock was triggered on GPU 1 – the hash rate dropped to ≈42Mh / s.

Testing with additional arguments in the miner did not show the stability of the hash rate over a long period of operation and was discontinued because the developers presented the next version of the miner.

Conclusion: with the help of GMiner 2.67beta, you can partially unblock LHR: the hashrate in the miner is ≈78Mh / s, which is ≈67% of the potentially maximum possible hashrate. To combat a drop in the hash rate, you can use a watchdog, which restarts the miner if the hash rate falls below a certain value.

How unlock LHR works with GMiner 2.67

On September 12, 2021, the development team announced GMiner 2.67. LHR unlock options are the same as for GMiner 2.67beta: —lhr 1, —lhr_tune1, —lhr_tune2.

You can download the miner and read about the release features here.

Let’s start the miner on our RIG with the following video card settings: PL (%): 70, CC (MHz): +0, MC (MHz): +1000.

Bat-file: miner.exe -a ethash —server eth.2miners.com:2020 -u WALLET_ADDRESS.RIG_3080ti -t 70 —log_newjob 0 pause

Immediately after the start, the miner shows the speed on the Ethash algorithm ≈70Mh / s – ≈83Mh / s, and after three minutes of operation it stabilizes at ≈78Mh / s. Memory Controller Load, GPU Load and Board Power Draw charts (like other Power charts) with significant “jumps” in parameters. To check the stability, we left the miner working for several hours, and after three hours a lock was triggered on GPU 1 – the hash rate dropped to ≈43Mh / s.

Testing with additional arguments in the miner —lhr_tune1 -10 and —lhr_tune2 -10 did not show the stability of the hash rate over an interval of more than 48 hours: three minutes after the start of work, the hash rate stabilizes at ≈74Mh / s, after 24 – 36 hours of operation on one of the video cards (in different tests in different ways) lock is triggered: the hash rate drops to ≈43Mh / s.

Conclusion: with the help of GMiner 2.67, you can partially unblock LHR: the hashrate in the miner is ≈78Mh / s, which is ≈67% of the potentially maximum possible hashrate. To combat a drop in the hash rate, you can use a watchdog, which restarts the miner if the hash rate falls below a certain value.

How unlock LHR works with GMiner 2.68

On September 15, 2021, the development team announced GMiner 2.68. LHR unlock options are the same as for GMiner 2.67: —lhr 1, —lhr_tune1, —lhr_tune2. In addition, in this version of the miner, the developers announced the detection of LHR blocking, automatic unlocking and continuation of mining, as well as displaying the miner’s restart counter with a watchdog timer.

You can download the miner and read about the release features here.

Let’s start the miner on our RIG with the following video card settings: PL (%): 70, CC (MHz): +0, MC (MHz): +1000.

Bat-file: miner.exe -a ethash —server eth.2miners.com:2020 -u WALLET_ADDRESS.RIG_3080ti -t 70 —log_newjob 0 pause

The miner worked for more than 17 hours, the speed on the Ethash algorithm ≈77Mh / s. Memory Controller Load, GPU Load and Board Power Draw charts (like other Power charts) with significant “jumps” in parameters.

The result of the miner’s work on the statistics page on the 2Miners mining pool website looks like this.

The average hash rate is 158.77Mh / s – or ≈79Mh / s per card.

Now let’s test the miner with the -lhr_tune1 parameter. The maximum positive value of this parameter (from -10 to 10) increases performance: positive values ​​increase performance, negative values ​​decrease probability of lock.

Let’s start the miner with the following video card settings: PL (%): 70, CC (MHz): +0, MC (MHz): +1000.

Bat-file: miner.exe -a ethash —server eth.2miners.com:2020 -u WALLET_ADDRESS.RIG_3080ti -t 70 -tm 110 —log_newjob 0 —log_date 1 —logfile log_RIG_3080Ti.txt —lhr_tune1 10 pause

From the very beginning of the miner, locks / unlocks occur: GPU Lock detected, unlocking / Unlocked. It can be seen that one Lock / Unlocked cycle of each video card lasts 30 seconds. At this time, the hash rate of the card is zero. Full information about the miner’s operation is saved in a log file, the number of Lock / Unlocked cycles can be accurately calculated.

Now let’s test the miner with the -lhr_tune1 parameter 4. Start the miner with the following graphics card settings: PL (%): 70, CC (MHz): +0, MC (MHz): +1000.

Bat-file: miner.exe -a ethash —server eth.2miners.com:2020 -u WALLET_ADDRESS.RIG_3080ti -t 70 -tm 110 —log_newjob 0 —log_date 1 —logfile log_RIG_3080Ti.txt —lhr_tune1 4 pause

During the first 15 minutes of the miner’s operation, there was only one lock / unlock cycle: GPU Lock detected, unlocking / Unlocked. Therefore, it was decided to continue testing on an interval of 24 hours.

The miner worked for more than 26 hours, the speed in the miner on the Ethash algorithm ≈78Mh / s. Memory Controller Load, GPU Load and Board Power Draw charts (like other Power charts) with significant “jumps” in parameters. When analyzing the log file, it was found that there were only 8 Lock / Unlocked cycles in 26 hours.

The result of the miner’s work on the statistics page on the pool website looks like this.

Let’s estimate the hash rate for 26 hours of miner’s work, based on the number of shares sent to the pool. Initial data: 1644 balls in 26 hours, ball difficulty 8726M. Multiplying the number of balls per second by the complexity of the ball, we get 153.26Mh / s. This is the hash rate of two video cards, therefore, the hash rate of each is ≈76.6Mh / s.

For a statistically correct result, we recommend a longer testing interval: each card must send more than 5000 shares to the pool.

Conclusion: with the help of GMiner 2.68, you can partially unblock LHR: the hashrate in the miner is ≈78Mh / s, which is ≈67% of the potentially maximum possible hashrate. LHR lock detection, auto unlock and continue mining works efficiently. For stable mining with an increased hash rate, you can use —lhr_tune1 and —lhr_tune2 with parameter values ​​of 5 or less.

How unlock LHR works with GMiner 2.69

On September 24, 2021, the development team announced GMiner 2.69. LHR unlock options are the same as for GMiner 2.68: —lhr 1, —lhr_tune1, —lhr_tune2. LHR lock detection, automatic unlocking and continuation of mining are saved, as well as display of the miner restart counter by a watchdog timer. New: Added auto-tuning for LHR GPUs, improved miner stability.

During the first 15 minutes of the miner’s operation, there was not a single blockage. Therefore, it was decided to continue testing at a longer interval.

The miner worked for more than 15 hours, the speed in the miner on the Ethash algorithm ≈77Mh / s. Memory Controller Load, GPU Load and Board Power Draw charts (like other Power charts) with significant “jumps” in parameters. When analyzing the log file, it was found that there were only 4 Lock / Unlocked cycles in 15 hours.

How much can you earn with one video card?

Having some idea of ​​how to make money on a video card, you should know which video adapters are best for mining. An excellent option would be AMD Radeon 5 series and above. Since the total amount of your earnings will depend on the performance of this device, it is recommended to acquire flagships.

It is believed that when using AMD graphics cards, the computing speed is slightly higher than that of analogs under the nVidia brand. But it strongly depends on the calculation algorithm on which each specific cryptocurrency is built. Accordingly, the more calculations per second, the more significant your earnings.

It is important to remember that if you decide to mine using one, even the most top-end video card, its performance will not be enough. You will spend a lot of time before you get 1 BTC. For example, if the GPU Radeon HD 7970 is involved, your result will be about 555 MH / s, and the daily production will be at the level of 0.0031 BTC, or 80 cents. It should be borne in mind that during mining, electricity consumption increases. Therefore, this method of mining cryptocurrency is considered impractical.

Final conclusions: how best to mine on LHR video cards

GMiner’s development team has come up with a one-stop solution for unlocking LHR graphics cards. With the help of GMiner, you can partially unblock LHR: the hashrate in the miner is ≈78Mh / s, which is ≈67% of the potentially maximum possible hashrate. When using GMiner 2.67beta and GMiner 2.67, it is better to use watchdog, which restarts the miner if the hash rate falls below a certain value.

For finer tuning, you can use the —lhr_tune1 and —lhr_tune2 parameters, taking into account the rule: positive values ​​increase performance, negative values ​​reduce the likelihood of blocking.

Please note that we did not test on the most extreme graphics card settings. Your samples, for example, can work steadily at higher video memory frequencies. Overclock and test each video card individually.

We know from the community experience that GeForce RTX 3080 Ti can reach speeds of ≈85Mh / s with the following settings: CC (MHz): 1260, MC (MHz): +1350 (for Linux +2700), Power 280W, —lhr_tune1 3 …
