Mining: RX 480 Hashrate – Overclocking | BIOS| Eth| Benchmark | Profit (Surprising)

Rx 480 BIOS firmware

The firmware is a change in the value of the timings, which determines the mining. To flash a video card, you need four programs:

• ATIWinFlash
• CPU-Z
• Poraris Bios Editor
• Atikmdag patches

Further it is necessary:

1. Run AtiWinFlash and save the BIOS file.
2. If there is more than one card, then you need to flash them in turn, and it is advisable to make a backup of the BIOS files of each video card.
3. After, c Polaris Bios Editor open the saved BIOS file and change the timings.
4. Copy the value from the Value string 1500 and insert 2000, 1750 and 1625 and save the file.
5. Run ATIWinFlash and “load image”.
6. After downloading and installing, the firmware will complete.
7. Before rebooting, you need to run Atikmdag patchesotherwise the system may not detect the video card.

BIOS flashing entails a loss of warranty, be careful.

The SRBPolarisV3.5 application allows you not only to edit the timings, but also to lower the memory and core voltage. However, the latest versions Claymore’s Dual Miner 15 and PhoenixMiner_5.0e_Windows allow you to perform undervolting and change timings on the fly. Add the necessary parameters to the executable file and the program will do everything by itself. In this case, you will not lose your right to warranty service.

Overclocking in working order

To understand how to overclock an AMD video card, you need to learn how to manipulate the operating frequency of the RAM. For overclocking use programs MSI Afterburner or Wattol, which can be downloaded from the official sites.

For overclocking in the program Afterburner the values ​​are used:

• Core frequency (Core Clock).
• Memory frequencies (Memory Clock).

For the most profitable overclocking when mining ETH, increase the Memory frequency parameter by +30 MHz. The optimal value if the video card has been correctly flashed is about 2050 MHz. For mining other algorithms, it will often be necessary to increase the frequency of the processor of the video card, but remember that with this increase, the power consumption increases significantly.
