Ethereum Mining Profitable Again

Lots of people have been interested in my AMD RX580 BIOS mod:

Original (you should make your own…but just in case):

Modded with 1750 over 2000 straps:

Now is a good time to be mining some Ethereum, and if you want to improve your performance, these BIOS mods may be what you are looking for! Check out CryptoCompare.com’s Calculator (modify to your specs of course):

https://www.cryptocompare.com/mining/calculator/eth?HashingPower=58&HashingUnit=MH%2Fs&PowerConsumption=400&CostPerkWh=0.16&MiningPoolFee=1

I am currently running them with 28+MH/s on Phoenix Miner on EthOS. Your mileage may vary:

GPU1: 65C 100% 125W, GPU2: 59C 100% 127W
GPUs power: 252.0 W
Eth speed: 56.351 MH/s, shares: 2356/0/0, time: 116:14
GPUs: 1: 28.264 MH/s (1171) 2: 28.087 MH/s (1185)

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:

Amazon: http://amzn.to/2rptIVP

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 editorto 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.

*** 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! 🙂

If you find these helpful and want to chip in for a beer (or a few) – Thank you!
