Once you’ve selected the appropriate ASIC mining device for your desired cryptocurrency, you need to improve it. Here are some suggestions on how to optimize the mining hardware to improve efficiency and energy efficiency.

1. Undervolting
   Undervolting means cutting down the voltage supply to your mining equipment which reduces power consumption as well as overheating.
   Furthermore, undervolting is great to ensure an extremely high hash rate and decreasing the load put on hardware. The lower the power usage, the better power efficiency, and the more mining profit.
   Undervolting must be performed gradually, after constantly checking the hardware to ensure its stability.

2. Mine During Off-Peak Hours
   Certain electricity companies offer discounted costs during off-peak times. If you can, take advantage of that to cut down on the operating cost.

3. Overclocking
   Overclocking refers to raising the operating frequency that your ASIC miners over the default settings to improve the mining efficiency. Miners can overclock their ASICs to boost hash rates which increases their chance of success in mining.

However, excessive overclocking could cause a rise in power consumption and overheating of the machine. Thus, it’s best to gradually increase the speed of your overclock, rather than abruptly.
