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

[heavyarms1912]

Also in my experience the Win 10 would deliver 940 at those clocks with two threads.  Two threads just doesn't help in linux.  At least it didn't work for me.

Which miner are you using there on windows 10 to achieve 940H/s?

xmr-stak-amd.

Hi everyone,

Finally took the risk and flashed the bios of my XFX RX 470 RS (4GB, Single Fan edition) setting the straps to the 1500 Mhz setting.

This card has Hynix H5GC4H24AJR chips, and pretty much the default timings.

So anyway, after setting all 1500 Mhz and above to the "7770..." straps, i rebooted the card and everything works and right now I also overclocked the memory to 1795 Mhz from the default of 1750 Mhz and everything seems to work fine. (right now monitoring to see if I get gpu errors and may try to go up to 1900 mhz on memory later)

Claymore reports an average hash rate of 18.5-19 mh/s - the highest value I've seen was 19.055 mh/s.. it's a small step up from around 17.5..18.3 mh/s before the changes.

So my questions..

1. I'd like to hear your opinion on this, is it a normal hash rate for the current DAG #159 ? All the hash rates I found for this RX 470 are a few months old, so i'm not sure i'm doing something wrong or the complexity simply increased in the meantime
2. Compared to ethminer, claymore is faster for me but every 5-10 seconds mouse lags a bit and videos also freeze for half a second or so every once in a while in MPC-HC (Media Player Classic Home Cinema), in Youtube movies plays fine. Will playing with the -ethi or -dcri parameters have some effect and if so, which one should I focus on? (right now they're on their defaults of 8 and 30)
3. How much increasing the power limit matters for this card? Will higher power limit give more power to memory as well, or it's just about gpu core?  Right now I set it on +10% power limit, but i don't see any noticeable power increase in gpu-z or the card running any different (frequency i left stock 1226 mhz)

Thanks to everyone answering..

edit : Oh, i forgot to mention.. I'm still on Windows 7 64bit and with older Catalyst 17.7.2 ... but somehow i doubt the latest driver would have significant improvements for this card.

1) Overclock memory to at-least 1825
2) Switch to the 17.11.1 drivers, the performance difference is significant

Is it possible to share your .rom file? I also need intensity and worksize values... I'm trying to increase hashrate for a week

I think yes you can share your rom but depends if they are the same memory type and model..
What hash speed you can get with your graphics card?

Why not brick the card...

guys i just bought a rx 570 4gb mini itx pulse ...

which driver i should use?
new adrenaline?

or old one?
need a patch i want to modify the bios?


thank you very much

Hi, when I do have R9 280x and HD 7950 with Hynix memories, can I use this guide, or it would not work for these old cards?

It won't work, and theres no tool to easily edit straps in those cards, except hex editor...AFAIK

Some new straps for polaris 20 cads ?
old straps can't exceeds 30 for new batches or maybe it is drivers issues ?
I returns 12 x Gigabyte RX 580 Gaming 8G because I can't exceeds good Hashrate

You returned perfectly good polaris cards because you were not able to exceed 30mh on them?
What were you expecting exactly? 40mh per card? What made u have such absurd expectations? Do you have any mining experience?
Do you understand that a better memory strap can help you push the last drop of mining performance out of a card, but it wouldn't change the card itself?
Do you understand how graphics chips, or memory chips, or any kind of chips work? Do you know the term silicon lottery?

Samsung I don't remember but I try every straps that I have
And hashrate was 25-26

Man, I have more than 20 RIGS ( by 12 cards, so this is more 240 cards) with RX570, RX580 all of them mining with 30,5+ (some with samsung 32)...

Well without exact type can't really help you. But even those mining cards RX 470 with sh*tty Samsung (FC type I think) I could get to at least 29MH/s... Even those lowest perform Samsungs do 28MH/s with classic Uber-mixes.

This doesn't mean you know what you are doing. Each GPU should be considered different. I know where your problem is and I've written about it, latest gigabyte 580 gaming g1 8GB with hynix/samsung don't come with standard IR compat VRM which leads to huge amount of heat produced by GPU and of course less stability. Considering this and the lack of 1500+ timings in bios users assume that flashing older vbios will fix their issue, well it won't. Got this fixed month ago for me and an US fellow who happen to have won the lottery getting only samsung G1 gaming's(hashing with 31+MH ether and 1100 cryptonote at very low power)

But he got those Samsung Not the H5GC8H24MJ

anyone has tips on how to mod bios for rx570 8gb!? i tried some basic stuff but it didn't work. it has 1: and 2: for the mhz on timing values. thanks

The easiest way is to use Polaris Bios Editor and select the "One Click Timing Patch" this will mod your BIOS for you, just save it and flash with ATI Winflash.
You could also try one of the BIOS's at the 'Anorak' web site, as you have not specified which make of RX570 you have just check out if a BIOS is available here: https://anorak.tech/c/downloads

I followed the instructions to a T and want to thank you so much for the dramatically increased results.  Here are my mining rig specs:

1 Gigabyte RX580 8GB (all Samsung mem):  Before ~710 H/s -> After 920-960 H/s
2 Gigabyte RX580 Arous 8GB cards (all Samsung mem):  Before ~720 H/s -> After 940-960 H/s
2 Asus RX580 Dual Fan 8GB cards (all Hynix mem):  Before ~550 H/s -> After ~750 H/s
1 XFX RX580 Dual Fan 8GB cards (mix of Samsung and Hynix mem):  Before ~760 H/s -> After ~960 H/s

I'm running an Asus Prime Z-270P with an Intel Pentium G4600 and 16GB of DDR4-2133 with Win10 Pro and Claymore miner mining ETN.
