BIOS firmware on RX 580
The firmware consists in changing one Bios to another, in which the timing settings for video memory are modified. Video cards with Samsung memory installed and so capable after overclocking can show hash rates up to 30 Mh / s.
To transform them, you need to use the special programs ATIWinflash and PolarisBiosEditor . A complete step-by-step guide to AMD Radeon RX firmware is available on our website. Thanks to this software, you can change the memory timings to those that are more suitable for mining. This will get the maximum hash rate.https://www.youtube.com/embed/c3AjeJa-BTE?wmode=transparent&rel=0&feature=oembed
But before flashing, it is worth remembering that the performance and safety of the video card depends on the user and in case of an unsuccessful firmware, the video card will fail. And you also need to find out in advance what memory is on the video card and see what timings are suitable for this manufacturer (Hynix, Elpida, Samsung, Micron) using the GPU-Z program .
Overclocking Radeon RX 580 4 and 8 GB
For mining, overclocking is not the same as for games. For overclocking, the popular and proven program, Afterburner , is perfect . For games, the overclocking is done gradually for the core and memory. And for mining, due to the difference in algorithms, you need to tune the core to a certain value and only then increase the memory frequency.
Overclocking occurs gradually, increasing the frequency of Core Clock and Memory Clock .So, in the case of the Radeon RX 580, a high core frequency is not needed to extract ether, the value of the memory frequency is important to it. Due to this, you can save on electricity, and also leave the card cold.
The exact values can be found out after experimentation and selection of the optimal parameters. After the initial settings, it is better for a certain period of time (1 day) to monitor the stability of the work and identify if there are any incorrect balls or errors. Their presence will mean that the RX 580 is overclocked.
If you write the –cclock / -mclock parameters in the miner’s batch file , you can overclock the cards without the Afterburner program. You can also change the memory and core frequencies directly in the AMD driver settings.
