sorry for un clarification above, and yes used ATI Pixel Patch and yes I'm using AtiWinflash, ofcourse, anyway still not near solving mine problem. Think solved 1 problem with MB beeps, just changed MB with Asrock H81 PRO BTC R2, and there is no beep, just one, and finally, I can boot windows with Radeon VGA as primary VGA.

Is it even possible to destroy a GPU just by using a hacked driver? I don't think so.

I know its possible to destory a GPU by a bios flash where it can alter the voltages and fry the card.

On a driver level? No sure.

Think I'm writing in so many places about mine problem, just one more is maybe gonna solve it. Well, the problem is on the VGA card: Sapphire nitro+ RX 580 4Gb Hynix, have 6 of them. First, have tested only 1 with flashing VGA bios with so many different mods, not even one works. The card has dual bios with the hardware switch, find some tutorial on youtube, need to move the switch in front where connections for the monitor are, and I did it  . Used couple tutorial "how to" flash bios, for this cards need Polaris 1.4 or 1.5 version, and atiflash 1.24 version, saved original, modded straps from 1:1500 to rest down straps (1:1500....1:2000). No problem there. After reboot I got a beeps 8 times from MB (Biostar TB250-BTC PRO v6.x with last bios 710). 8 beeps mean that there is VGA memory problem. After looking again how to, make an IGFX primary, there is a beep again, just windows show up. After that used couple drivers, but only version 17.4.4, works with a card and MSI afterburner (this is combo driver, not original find it here: https://www.youtube.com/watch?v=xCSuON1fvZ0). Well, after doing all that the hash rate was 24, 12, 23, 11, 24, 22, 21, ...... Just for a record, this is over 3 weeks experimenting with mods, drivers, afterburner. Used Claymore, of course, for under-volt and overclock, just never happened over 24Mh/s. I read all these pages here, some people have a similar problem, and I did what they describe, with no luck. After tonight I give up, have an over 30 pages of what I have tried, so many combinations, mods, drivers, etc,...The major problem is that driver not see the modded VGA bios.

I'm asking someone who has an exactly same card as mine and makes 28Mh/s or so, to write me here or on email (ser.robert.ilic@gmail.com) step by step, how to, any help will be gladly accepted.

Thanks for your time

1. Okay is this a whole new driver or can I patch my 16.9.2 driver with this one?
2. I am using wattool right now. No need for MSI right?

Everything else is the same right?

I have the xfx rx 480 4gb (elpida) and I am receiving the core 43 error when I try to install. Why???

There is something wrong with both 16X PCIE, beacuse in BIOS under Advanced-PEG Port Configuration option PCIEX16_1 is set to NOT PRESENT !!! I can't change that value, on working motherboard in other rig, this setting is set to x1.

I cant, not with latest trixx, not with AB beta 16.

If you're referring to later drivers blocking modified BIOS, I've run latest ati patcher with all attributes "found" and successfully patched, restarted and the error is still present. I do think the memory labels in BIOS editor showing up scrambled is a sign that this could be a new revision that the usual tools don't 100% work with. I've also tried the old Catalyst 16 driver with the Safe Mode - F7 then patcher trick without success.

Hi another time....please any ideas about my question?

How i can change the voltage etc for each card ? At moment is teaking all cards the same voltage values which I write in the claymore config :(0

Mattthev check inbox, I have RX 470 Mining edition (Samsung chipse), I'm finding the best hash for that GPU, please help me.

Hi, in 4gb cards like 580 should y copy 1:1500 and 2:1500 to 2000 or just 1:1750 and 2:1750 like tutorial

Thanks!

Can anyone help me understand why my GPU's will require 10-30W more power all of a sudden, after changing nothing except the location.

Same hash rate, same temperature - but each card is consuming between 10 to 30 W more power... all of a sudden?

thanks for this guide Mattthev, it was extremely helpful. i am however experiencing some small caveats.

I went ahead and modded my XFX RX480 8GB OC version (XFX Radeon GTR RX 480 DirectX 12 RX-480P8DBA6 8GB 256-Bit GDDR5) one by one.

went from stock hashrates of ~650's to a range of 859 h/s to 878h/s mining XMR with claymore, and is remaining pretty stable at the moment (maybe i'll have to report back later)

However, its doing ~960W at the wall for 5 cards and the Claymore software doesn't display the temp of the cards and the fanspeed anymore. Also, If i tinker with anything through MSI Afterburner, the hash rates immediately drop to ~250 h/s per card. What do you think the problems might be?

I'll be PMing you as well for additional help!

If i have all the Same cards
Is it better to save, edit and flash back the own card bios from euch card or can i mod One bios and flash this to each card?

Thank you very much for your response. Sorry for this noob question. But I dont know which straps I will use for my MSI RX580 Gaming X (Samsung). Is it the 2000? Or both 1750 and 2000. I`ve seen the instruction that for 580, just copy the uber mix to both 1750 and 2000. However, I`ve also read some comments that they just copy it to 2000 only.  Can you help me which one do I need to do to get the best mining performance on my gpu? Thank you very much.

Hi, just want to ask if the Uber mix 3.1 is tested for RX 580 specifically for MSI RX 580 Gaming X (samsung)? And do I need to copy and paste the uber mix 3.1 to both 1750 and 2000 timings and not on the 2000 timing only? And also, will it lower my GPU power consumption even if I just edited the timings and not the voltage in the Bios Editor? Thank you very much.

Is this the 470 11256-31-21G (bios 113-2E353FU.M58) with Samsung K4G41325FC memory?  If so I may be interested in some help.  I have the cards running 27.7MH's with 1200 clock / 1900 memory using 1750 straps.  I can't get any of the cards to run higher than 1900mhz.
