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

[wizzra]

Here are my steps:

1. Switch to High /Low switch on the card, Bios 3 and backed them up.
2. Tried to flash the bought bios from @Mattthev website with ATIWinFlash, but it failed, with an error "SubSystemID mismatch" or something that like,
3. Loading Polaris 1.4.1 showed no timings, so i loaded Polaris 1.6.7 and it worked fine, and here are the differences between my bios and the bought bios:

Original:
VendorID: 0x5249
DeviceID: 0x1002
Sub ID: 0x387E
Sub Vendor ID: 0x174B

Bought Bios
VendorID: 0x5249
DeviceID: 0x1002
Sub ID: 0x353E
Sub Vendor ID: 0x174B

So what now?
Do I replace the bought bios' Sub ID with mine? (patch on polaris)

Or how else do I flash?

I have 7 MSI Armor RX 580 AMD GPUs.  They're each getting about 29-30 MH/s, but they're using about 175W each.  Even more with dual mining.  I've tried several suggestions for undervolting but nothing seems to work.  I'm using Claymore through Simple Mining OS.  Should I move to Win 10?  I really like SMOS, but the voltage issues are killing me.  I've recently read the first post in this thread that undervolting only works with Windows.  Any suggestions ?

Send me your bios via e-mail.

@Both of the previous replies,

wow that was dumb, i think i just kinda forgot about it and i redid everything and all worked out.

Running a solid 168 MH/s with 6 cards on 875Watts.

I do have a question tho, is there much of a different between power saving mode or OC/Undervolt mode in the PBE 2.1?

I kinda don't want to do all my cards again right now that i got everything working just to find out it doesn't change much

So that's 28MH/s per card. I get the same with free timings, aren't your timings supposed to give better hashrate?

Hello Mattthev
I don't find the moded bios for my card, is a Sapphire Pulse RX560 OC 4GB with SK Hynix, and you only have the Micron version, i send you a copy to know if you can mod it!

Thanks!

Depends on card, memory type, quality, OC, miner, etc.

I now try to buy this BIOS (https://mining-bios.eu/product/mining-bios-sapphire-nitro-rx-570-4gb-elpida-hynix-pro-performance-timings/)
I add it to cart and apply discount, total cost 21 $, but, when i try to pay its show me 27$ with discout,why ?

What? Price is 30 USD.
This is not support thread for the store!

Seems like I need more testers for performance timings. Looking for every memory types. You have to know how to use PBE or SRB and tweak cards for best hashrate.

Hi,

First time using the PBE, attempting to flash an RX 480 4G with Hynix VRAM, it was doing 22 MH/s stock with compute mode,

I flashed it using the one click button BIOS and it was then doing 17 MH/s, but after restart the BIOS was also no longer detected by AMD settings, I was trying to check if it was in compute mode at 17MH/s.. but even GPUZ had trouble identifying the card, ATI Flash simply labeled it has "Polaris", I reverted back to stock BIOS after that, but I really think 22 MH/s is low for a 480, any suggestions? Also, when I use afterburner I cannot do anything above stock or the hashrate falls, this indicates VRAM errors correct?

I did a clean install and installed the pixel clock etc etc, what am I doing wrong here? What specific order do I need to everything in just to be sure I am not screwing it up?

Thanks!

Hello, this concerning 2 rx550 cards by Sapphire. I got the newest Polaris editor, as well as ATIflash and the patcher program.

Did the first card, using only one click tuning. Rebooted, ran the patcher, card is fine.

2nd card did not do so well. It reported no problems, but now comes up as standard VGA adapter, even with the driver installed. I cannot reflash the original BIOS on it b/c ATIflash does not detect it.

What can i do with this?

Flash it in safe mode.

Thank you Matththev for useful thread, I'm a newbie in mining world, have just bought 6 cards FXF RX470 8G. Still don't know how to control fan speed? The seller had set up it's speed always be 100%, but all temperature just only 40~60°C. 

[jakkwb]

matthev, the atiwinflash program will not run in safe mode, it tells me "due to Microsoft Win7 Enhanced security features, this application requires the user to be in administrator mode..."

Which I am doing by right-clicking and running as admin in safe mode.

This is Win7pro 64bit.

If you want mine for same card with same hashrates I have no problem to share, you can thank me later with some coins

Check that you may have to run pixelpatcher again. I sometimes find that the ATI driver has decided to update itself (even if I tell it not to) which disables the pixelpatcher fix causing the GPU to run in low-res only.

[jakkwb]

Ran the pixelpatcher again, rebooted. No change, 2nd card still shows as standard VGA adapter with a code 10 error.

You disabled shapeshift integration, i wanna bout the pbe pack but i dont really have BTC right now or LTC anything i can do?
