Modified GPU BIOS for Mining

[TheSloppyBeaver]

alright commented out the overclocks set to run only off bios config, it works and its reporting the exact hash rate as the rig, except it is no diferent than my original bios mod except the extra power use. before i had 737 @ 89w now i have 740 @ 110w

Can you help me with my sapphire rx 480?

Well you're doing something wrong if those are the numbers you're reporting. I have the core set to 1188, the memory set to 1888, the VRM set to 2000 and the voltage set to 0.888V so there's no way this is using more power than the stock bios. Are you already running a modded bios?

Download gpu-z and lets see what's actually going on here, something is probably overriding the bios settings.

You need pixelpatcher to disable windows driver signature checking on 480 cards, linux checks but doesn't disable your card like windows. Windows doesn't enforce signatures on 580 cards.

Any tips or existing bios mods for this card?
How much MHs is possible for ETH mining with this card?

Yes, I modded the straps for both types of memory. However it looks like I used the old strap for Elpida, it should still work OK.







edit:

I updated it with the newer Elpida strap.

^^^ Memory is running at 1888, I've got a 570 with the same issue. I need to do some testing on it and I'll get back to you in a bit...

I just got a bunch of these Asus Radeon RX570's with 4 GB RAM and ELPIDA memory
Outta the box on Ethminer they run about 21.5 MH/S

I was wondering if you have any mods for this card?

I doubt these can do the magic 30 MH/S but I would love to see a stable 26 or more.

Thanks!

No reason they should not hit 30 if memory cooling is done reasonably good

Awesome. Hope notbatman has a mod for me to test.

**** If you click "download" on any ROM(s) I post from pastebin.com then "save as" a .uue file then extract the compressed .7z archive with WinRAR, WinZip, etc.. and the bios_file.rom will be inside the .7z

Ok tried that.

In real life here is what happens.

Click on "download" and it automatically downloads as a txt file. No option to "save as".

I tried opening the txt file in notepad and then saving as .uue

But after that 7z will not extract it as it does not recognize it as a archive file.

What am I doing wrong? Better yet how about hosting ROM's on Google Drive or something.

Thanks
