Asus RX 580 8GB (DUAL-RX580-OG) Mining Bios Mod

I picked up a few Asus RX 580 for mining Ethereum and some other Altcoins:


They have 8GB of Samsung memory with this Bios label: 115-D009PI2-101

I basically dumped the bios using atiflash in EthOS and transferred it to my Windows PC. Used the forked Polaris Bios editor to set 1750 straps on 2000 and saved. Moved back and flashed. I went from 24.5 to 27.5 MH/s on Ethereum. I’m playing with CPU and Memory timings in Claymore now…I hear we should be able to get 30 Mh/s out of these bad boys 😉

I’ve flashed them and have been using them for several days now with no issues.

Original (you should make your own…but just in case):
Modded with 1750 over 2000 straps:

*** I’m not a pro modder! This is a very basic (and what I believe to be safe) tweak. I give a standard disclaimer on these…but they should be safe.***

Now that’s out of the way – Enjoy! 🙂
