6.4 Overclocking Recommendations

• Set PSU Power Max to the maximum power limit of the unit, not exceeding 3900–4000 W.
• Set PSU Power Limit to a “safe” power level suitable for long‑term operation, but not exceeding 3800–3900 W. It is strongly discouraged to exceed the factory limit.
• The difference between PSU Power Max and PSU Power Limit must be at least 200 W.
• Set approximate Target Frequency and Target Voltage, using stock values as a reference.
• Set Minimum Voltage and Maximum Voltage within –50 and +50 of the desired Target Voltage.

During auto‑tuning, the miner will select the optimal operating mode.

You can also set identical target, minimum, and maximum voltage values (for example, 1430 / 1430 / 1430). In this case, the miner will not adjust the voltage, and the auto‑tuning time will be reduced. However, it is recommended to “give the miner freedom” to adjust the voltage.

During overclocking, the following reference formulas can be used:

• Target Frequency = F_Target_Normal * ( Percent + 100) / 100
• PSU Power Limit = P_Limit_Normal * ( Percent + 100) / 100
• Target Voltage = V_Target_Normal  * ( Percent / 5.0 + 100) / 100

Where:

• F_Target_Normal, P_Limit_Normal, V_Target_Normal – baseline (initial or “stock”) values of the target frequency, power, and voltage.
• Percent – the percentage of overclocking.

Example of Overclocking WhatsMiner M32 at 4.3%

Base (stock) values of this miner:

F_Target_Normal = 853, P_Limit_Normal = 3600, V_Target_Normal = 1380 

Thus,

• Target Frequency = 853 * ( 4,3 + 100) / 100 ~= 890
• PSU Power Limit = 3600 * ( 4,3+ 100) / 100 ~= 3755
• Target Voltage = 1380  * ( 4,3 / 5.0 + 100) / 100 ~= 1392
• Minimum Voltage = 1392 - 100 ~= 1300
• Maximum Voltage = 1392 + 100 ~= 1500
• PSU Power Max = 3755 + 100 ~= 3850
