Overclocking AMD Radeon Vega 56
At standard settings, any graphics accelerator in mining is unprofitable. The video card needs overclocking in mining, otherwise it will consume electricity in vain.
Using the program MSI Afterburner it is possible to quickly overclock the video card. Optimal values are selected individually for each video card. For this video card, the optimal kernel settings will be:
- Core Clock +100
- Memory Clock +600
- Power Limit 80
The hashing speed increases and the graphics card becomes profitable. For rx 56 vega overclocking settings, you can also use the utility WattTool.
How to reduce energy consumption
A powerful 3D graphics accelerator is a rather power-hungry device. The consumption of Vega 56 in mining is higher than that stated by the manufacturer in the technical parameters of the video card. To avoid excessively high electricity bills, undervolting (lowering the core voltage) is required. Will help here again WattTool program.
In the program window, you need to change the voltage indicators in points P6 and P7(when controlled in manual mode, the voltage at lower frequencies will drop automatically). For the rx 56 vega, a 12% reduction (1.070 mV) is optimal, which will reduce the consumption of vega 56 in mining by 50 watts.
Also in the program MSI Afterburner conveniently adjustable tension by stitching Power Limit. The optimal value is 80%, some video cards are able to hold a lower voltage, which has a positive effect on the payback period of the video card.
