[GUIDE][TUTORIAL][XMR,ETH]How To Mod Bios RX470/570/480/580 VEGA Mining 💰⛏

[Slugit]

I have red devil 570's...

Some hynix, mostly Elpida...

I used the Polaris Bios Editor 1-click patch, reduced the memory voltages to 900, and upped all my results by 10-15%...

Dropped all the temperatures and made everything more stable too... (had to change all my memory timings, but was worth it)

You also need OC the memory, most of your cards has only 27MH/s. Or better timings.

Hi,

I followed the tutorial and now I get around 29.3 mh/s, but I also have a lot of memory errors.

Could someone share their Config for one of those cards?
RX480 MSI Gaming X 8GB (Samsung)
RX470 Nitro 8GB (Micron)
RX470 Nitro + 8GB (Samsung)

You may try Uber-mix 3.2, I also have better Samsung timings. Or lower memory clocks.

I followed the tutorial and got about 28.5 mh/s for Each card individually. When I connect all cards I get no video signal.
Installed an older driver (16.9) with ddu and did anything I could think of. Now I get one card 28 and the other one 4 because it only runs on 300 mhz. The others still dont work together.

Do you have an idea what I did wrong or have an Image for One of those cards?

Rx470 nitro 8gb micron
Rx470 nitro + 8 gb samsung
Rx480 msi gaming x 8gb samsung

Thank you so much for your help!

Help! I wrote over the Silent bios for my Nitro+ 570 8gb Hynix card. Does anyone have a copy? I really need it!!

Use VGA bios databse: https://www.techpowerup.com/vgabios/193806/193806
Or the Anorak's...

Hi All!

I got one modded BIOS for my "Asus ROG STRIX RX 580 O8G GAMING" card (I saved my BIOS, uploaded to a website and got one back from a modder). BUT without checking what exactly he had modified, I doesn't want to flash it, so I compared with SRBPolaris V3 my stock BIOS version with the modded one.

This is what he has done:

- copied the memory timing of 1750 into 2000 strap
- changed the GPU default frequency from 1360Mhz to 1088Mhz
- changed the Memory default frequency from 2000MHz to 2140Mhz
- changed the Max Power limit from 180W to 160W in PowerTune
- changed the TDP from 145W to 122W in PowerTune
- changed the TDC from 149A to 126A

What do you guys think? Is this so OK if I want a little bit more hashrate and less power draw, with stable long term mining?

Thx a lot

Hi,

Says Mal can someone here adapt a guide to the Vega 56 and Vega 64?

Somehow I have my problems.

thank you

Your links are totally useless for Vega64 with blockchain drivers and contain long miner redirection virus. Total bullshit

What virus? It's javascript miner and it's stated there. I got at least some tips from that. I don't have any Vega so you might do a guide and I will add it to first post or point it to your post. What is bullshit about that? I'm pretty sure that the reddit post was one of the first and it contains all the info you need for setting Vega 64 to mine more effectively.

Looking for guys with Hynix H5GC8H24MJ cards for testing timings. Contact me via e-mail I will send you the timings. Only for those who know how to mod bios like this and will share results with me. Thanks.

I'm curious about the new Gigabyte RX 580 Gaming 8GB from September or August with top 1500MHz strap? Does anybody have it?
