Mining equipment is quite expensive, so miners try to buy powerful ASICs at a low price and then increase their performance to the level of more expensive models. We need to find out if this is harmful to the facility. To accomplish this, we need to review a few of the main ways to overclock a mining device, list the main difficulties, and see how such a performance boost affects the ASIC. Overclocking methods The main ways of overclocking the ASIC:
-
- Install a more powerful power supply;
- Change to custom firmware;
- Activate other options.
Each option should be discussed separately. Installing a more powerful power supply Devices with low hash rates can be overclocked with additional programs, but will not achieve the desired effect if you leave the standard power supply. This causes miners to purchase and install a more powerful power supply to provide the ASIC with the necessary amount of electricity. Reprogramming Standard device settings allow you to increase performance without installing additional software. But not every miner can cope with the parameters of standard firmware and the result often falls short of expectations. More experienced miners use custom firmware that is developed for ASICs to improve their performance. The standard software current for the device is used.
With successful development, an increase in ASIC performance of 15-20% can be achieved and the payback time can be shortened. Some custom firmware also increases the reliability of the device. Additional options Additional features may be hidden from users, as is the case with the Bitmain Z9 Mini ASIC settings, for example. Simply open the configuration page in your browser, right-click on the available space and select “View Source” or “Inspection” from the pop-up menu. If you examine the code carefully, you can see a commented out “Turbo” option that does not appear in the graphical menu. If you uncomment and save the settings, you can increase the ASIC performance to 550 MHz. Bitmain Z9 Mini can be easily overclocked to a hash rate of 15 K/Sol without changing the stability of operation. Overclocking Difficulties When overclocking an ASIC using additional tools that require the purchase of new power supplies, it is worth considering the economics. Blocks that actually provide 1800 W on a 12V line can cost up to 10,000 CZK. If the price of the used ASICs does not exceed 25000 CZK, you should consider buying another device that will be more powerful without overclocking. You should also consider the power consumption that will be allocated to the operation of such equipment.
Electricity bills may be of interest to energy suppliers if mining is done in a multi-unit dwelling. Reprogramming should also be mentioned. Not every device has its own software without negatively affecting the stability of operation. You should consider this before purchasing an ASIC. Possible consequences of overclocking One of the most obvious negative consequences of overclocking ASICs is device overheating. The built-in cooling cannot maintain the correct temperature if the user increases the power of the device. Additional fans need to be installed to solve this problem. The room used for the location of the mining farms is equipped with air conditioning. It is important to take into account the cost of additional equipment, as purchasing it can significantly extend the payback period of the initial investment.
Certain ASICs cannot be overclocked precisely because of the significant temperature increase. Their design fails to dissipate heat efficiently at higher power settings, leading to overheating of the chips and shortening their lifetime. Overclocking such devices would cause excessive stress and could lead to their failure.
Another possible consequence of overclocking ASICs is loss of warranty. Mining equipment manufacturers usually set permissible power limits and do not allow overclocking of the equipment. If overclocking is performed and the device is damaged, it may void the warranty and the user would have to bear all repair or replacement costs.
Another important aspect is the stability of the mining process. Overclocking the ASIC can cause instability, unwanted reboots, or device crashes. This would lead to a loss of mining power and efficiency, and thus less profits from cryptocurrency mining.
It is important to note that ASIC overclocking is often performed beyond the manufacturer’s official performance specifications. This means that it brings risks and complications that users should take into account when deciding to overclock their devices.
Overall, overclocking ASICs can provide some benefits in the form of increased performance and shorter ROI times. However, it is important to be aware of the potential difficulties and consequences associated with this practice, including overheating, loss of warranty and instability. Before overclocking, it is advisable to carefully consider the economic viability and conduct detailed research and consultation with experts.
