How to reduce power consumption

The graphics accelerator is a power-hungry device. Consumption of RX 470 in mining is higher than in game mode. To save power, lower the core voltage using MSI Afterburner . In the settings of the utility, you need  to open access to the voltage regulation , which allows you to change the parameters within 100 mV . To save on electricity bills and not lose the hash rate, it is necessary to reduce the Power Limit of video cards when overclocking the RX 470 mining rig .

When flashing the card, you can lower the memory and core voltage. To do this, open the BIOS in the SRBPolarisV 3 program, go to the Voltages section and enter the parameters manually. Then you need to save the BIOS and flash the card with it. Usually gpu of this line work stably at 875 Mv. If the rig restarts or the hash rate drops, you need to increase the voltage to 900 Mv or even 925 Mv. In Claymore’s 15 and Phoenix 5.5 miners, you can perform undervolting directly in the execution file. Just add -cvddc 900, -mvddc 900 to the batch file and you will reduce the consumption of the card in mining.

Attention! At low voltage, the –powlim value must be increased (up to about +40). You will not lose energy efficiency at all, ensure the stability of the work and the normal number of shares sent to the pool.

As a result, the card is flashed, overclocked and ready for cryptocurrency mining. Of course, one video card for mining is not enough, it is advisable to assemble a rig from at least 4 – 6 video cards. During the decline in prices for virtual coins, not everyone dared to make such costs. Many people bitterly regretted this. When the next upswing began, the equipment became scarce again and those who sold their farms, disillusioned with mining, lost potential income and were left with nothing.
