Anyone got a good BIOS mod for a Sapphire RX 470 8GB? Memory is micron. I'm able to edit the timing straps using the 1.4.1 bios editor but simply copying the 1500 straps only gives me a max stable hash rate of 25. MH (dual mining ETH). Any help on this is highly be appreciated. Original BIOS: https://expirebox.com/download/d680e04f8e0ce8881dca6e587a46831e.htmlI'll check it out in a few hours and see what can be done, I should be able to get you to 29.5 ETH/810 XMR. 900 xmr might be possible but without the card in hand to test I'm not going to force the memory to 2250. Did you manage to get Micron to 2250 stable? My highest is 2230 on RX560, any higher than that starts to get errors in hwinfo The only cards I'm currently running at 2250 are some powercolor rx560's with hynix. Only 4 out of 7 cards will run at 2250 and this memory is designed to run that fast. Running micron rx470 cards at 2250 is gong to be even more scetchy as they come at 1750 stock. Claymore just released a new xmr linux miner yesterday so I'll try setting my samsung and micron cards with his new miner first, if all goes well I'll flash the cards to that speed and post the bios'. But really, 2000 is the fastest most cheap cards will run stable at.

Although, someone gave me info that Powercolor uses R2C on Red Dragon RX560s, unlike Gigabytes R0C

^^^ Powercolor rx560-4gb mining OEM, nothing but problems... they're dirt cheap though. They should be almost identical to the red dragon.

I hope the info I posted proves that my Aorus RX580 8GB card exists.
Am still hoping notbatman and the other experts/experienced guys here can help me.

OK I'll mod that 8gb gigabyte stock bios in a bit, I'll set it to run at 2250 but there's a chance you'll get hardware errors at that speed. That being the case I'll post a 2000 version as well.
If you're lucky and it runs at 2250 you should get 34 Mh eth and 900 H xmr.

What timing that can get your memory run at 2250? Loose or Tight timing? Mine can only run at max 2100 though it get around 1025 h/s for xmr, but suck at eth.

thank you in advance notbatman, I hope things work out.
i will let it mine for you for 3 days as a thank you if we can get it to run at least 29MH/s at cool temps and reasonable power.
will PM you for your eth address.

^^^ UUE is supported by almost all major archivers, I can't help any archive format biased individuals or groups. A UUE file is a file encoded with uuencode, a Unix program that converts binary files to a text format. It stores the encoded textual representation of a binary file and must first be decoded to open the original file. UUE files are commonly used for emailing documents so the file does not become corrupted.
"UUE" stands for "Unix to Unix Encoding." It is most often used to transfer files between Unix-based systems. UUE files can be decoded to the original binary file with uudecode, or another UUE decoding utility.

Hi notbatman. Thank you for the modified bios and giving me the benefit of the doubt that this sucky card exists. I was able to download the bios you posted on pastebin saving it as a uue file. I used winzip to extract it as 7zip complained about errors opening you uue file. I extracted the 7z file and opened that with 7zip. I was able to extract the bios rom you provided. Before flashing, I first reset to default settings on AB and Trixx and flashed with atiflash. I then did full shutdown and cut power to the rig. Rebooting, I again reset defaults with AB and Trixx. core clock now defaults to 900 and mem clock defaults to 2250. I tried applying undervolt via Trixx but its not working. Result: No change in hashrate: 24.7Mh/s Slight drop in power use from 71.5w to 70w according to gpuz Lots of memory errors according to hwinfo. more than 50k in 3 minutes. ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fi65.tinypic.com%2F2mh7rie.png&t=665&c=9NqKOIN7qMRpsg) did you also use pbe 1.6.2? the bios rom you provided uses the same timings as my current modified bios. as far as I can tell, mem voltage was dropped to 880 from 1000 default. max gpu freq was dropped to 1100 from 2000 default. can you share what else you changed?
