Users often see in the console not the hash rate they expected from the purchased GPUs and ASICs. The difference is due to the peculiarities of counting. Effective speed is only one type of cryptocurrency mining speed. In programs, it often differs from the nominal hash rate of devices by 5-15%, which confuses users and does not give a clear understanding of the performance of the farm.
What is effective speed in a miner
This is the effective speed calculated by taking into account the number of orbs sent. It can be higher or lower than the theoretical performance, which is indicated by the developers of mining equipment. Because of this feature, the real profitability of a farm often differs from the predicted one.
The differences are due to the mechanism of mining in the pool. During operation, the following actions take place:
- The graphics cards or asics receive a New Job. This is a small section of the block that the equipment must process. By splitting large jobs in this way, pools pool capacity.
- The farm solves and sends a ball (the result of mining). It is needed to complete the search for the block.
- The pool checks the received fragment, accepts or rejects it.
The time of processing and sending the orb is affected by several factors – among them ping, antivirus problems. As a result, the search speed decreases, and the user sees that the equipment with a nominal 1000 Mh/s outputs, for example, 960 Mh/s or less.
Pools do not look at Speed and average when paying rewards. Only actual performance matters to them. Because of this, it is impossible to calculate income based on the nominal hash rate.

It is worth noting that some pools also have speed at pool or just at pool. This is the third type of speed, which is determined taking into account the number of not sent balls, but received. It can be very different from the effective one because of software and hardware errors.
What values to aim for
As in the case with hash rate, miners try to achieve the maximum values. On them depends on the contribution to the pool and, accordingly, income. The main thing is to stabilize the performance of video cards. Due to errors at the stage of configuration or assembly, the equipment can work at different speeds.
After about a day, the miner will calculate the effective hash rate with an error of 2-3%. It should be fixed and adhered to. If the parameter has fallen, it means that there was a minor malfunction that needs to be eliminated.
What is effective speed
This speed is often specified in the line together with at pool. Both parameters reflect the number of balls sent by the whole ring, not by individual video cards. Therefore, the difference between them in the miner console is rarely more than 0.2-0.5%. The indicator is determined every 5 minutes using a statistical method, because of which the calculations are not always accurate.
How to raise the speed
In addition to overclocking the existing equipment and buying new equipment, it is necessary to regularly check the condition and performance of video cards and asics. Due to minor hardware and software errors, the effective speed can drop down to 0. As a result, the user earns nothing, although ETH Speed remains at the same level.
The most common are 5 problems with the farm on video cards, the presence of which is worth checking if the performance unexpectedly dropped. It is also recommended to take them into account at the stage of building the farm.
| Description | Solution |
|---|---|
| It is necessary to reconnect the cables or replace them in case of damage. If the problem persists, you should contact the hardware manufacturer. | |
| A common problem associated with insufficient cooling. The devices work stably at 75-80°C. It is also worth checking the settings. Perhaps they mistakenly specify a low temperature threshold for disabling mining. | |
| Often occurs due to overheating. It leads to melting of the metal elements of the video card. As a result, the hashing speed drops. In this case, you need to resolder the boards or buy new parts. | |
| To work in the pool, you need a stable network connection. If it sometimes breaks, then the balls do not come or are delivered already outdated. You need to check the quality of the connection, switch from Wi-Fi to cable, and if necessary, change the provider. | |
| If you make a mistake in the URL of the pool, the names of the vorkers, the equipment will not connect to the network, but will work “idle”. It is recommended to reset the parameters and fill them in again. |
Conclusions
Effective speed in a miner is an important characteristic that determines the profitability of the farm. It is influenced not only by the number of video cards or asics in the ring, but also by the quality of the Internet, settings and other factors. It is the effective speed that determines the profitability of the farm. It is also the main indicator of the performance of devices. If the speed has fallen – it means that there are problems that need to be solved.
At the same time, you should not look at the Speed indicator. This parameter does not affect the mining process and profit.
Frequently Asked Questions
📣 Which video cards mine better – NVIDIA or AMD?
In WhatToMine’s hash rate ranking, the top 3 are RTX 30-series and 40-series devices. That’s why you should use NVIDIA graphics cards, although AMD can be overclocked better via MSI Afterburner.
📌 How to increase income from mining?
In addition to buying new asics and GPUs, it is worthwhile to increase the frequency of the devices. After changing the settings, they will mine cryptocurrency faster and with less power consumption.
🔥 Is it worth overclocking video cards?
Yes. It can increase profitability by 5-15%, but power consumption and wear and tear will increase.
✨ Does the amount of video memory affect hash rate?
Yes. If there is enough VRAM to store a DAG file, the card will be able to mine. If there is not enough video memory, coin mining only works in zombie mode, but performance drops by 1.7-95%.
🤑 How to calculate the profit from mining?
To do this, use special calculators – CryptoCalc, WhatToMine. They specify the hash rate or the model of the device.
