win10 pro / x64 latest AMD driver card has samsung memory
I tried to mod bios, I just copyed values from 1750 strap to 2000 strap. After bios flash and restart, my card is "unrecognised" by the system - I get that yellow exclamation in device manager. AFAIK that was the issue in win7 but not win10. Pls help, what am I missing here?

You should take some time to read past posts, on Win 10 you can't just ati flash and restart. You need to mod so that it 'appears' to be signed. There is a ton of info out there on this topic, I myself posted a similar issue in this same thread.
Guys, i tried to flash my Sapphire Nitro Rx480 4gb but i failed. Can someone share any rom for this card please?
I have the same problem, with a sapphire nitro rx 480 4gb.
Any solution?
Solved. Look for a rom according to the GPU and then flashing the rom, the problem was that there was an error in the flash, I solve it with a post from here.
Please forgive my ignorance. I flashed an rx480 xfx 8gb to get more hash rate and it got less. I flashed it back. My time is limited so I will pay an eth bounty for help. I have 2 rx 480 8gb with dual bios switch. I have two msi rx480 4gb armor editions. Don't laugh I got an xfx rx 560 hashing 12mh and 2 rx 550s at 8mh each. I need help to up my my rate. Not worried about power. My power is cheap here.
Hello, I own 2 Sapphire rx470 Nitro (non +) dc OC 4gb and i would like to flash bios. After saving the bios and open it with Polaris, at Timings, instead of default values, it shows some garbage values...no 1600, 1700, 1800 or 1900 values... Dont know what to do...and ideas ?
I have 2 rigs running with 6 sapphire rx480 8gb each. I'm getting 24 mhs in each card. I have two main questions. What are the recomended settings to increase mhs without flashing the bios. And the other question why any of my cards dont have the V bios switch that i see in most pics and videos.

Hi, I want to flash my RX480 8GB(Samsung) but when I open PolarisBiosEditor I have something like this And now I'm afraid to flash my card. Please help guys ;/
I've seen similar thing on Asus Strix cards, as long as you re-flash the original bios that you saved and then modified yourself, it should be okay to flash 256KB files.
Hello can anyone tell me how to OC a RX strix 480 8 gb. I m using Gpu Tweak II . What i have to put in GPU clock , GPU voltage , memory clock? Fanspeed? Power target ? My ring have Motherboard Bios pro TB-250 8 gb ram Power 1300 w gold I5 intel prossesor Win10 pro . 64 bit Rithg now each is 24 mh/s . But i would like to up.
Why to flash the cards ? Is it that huge difference with stock? The risk is that you brick the card right? .. im not familiar with changing bios and flashing etc.. guess i have to do it with stock.
The chance you brick you card is very small if u know what you are doing. If u got a card with a bios switch there is zero risk. U can just ask someone to do it for you, its worth the effort.

It's dead easy to mod the AMD cards.
Download the BIOS
Tweak it in the Polaris editor.
Flash the BIOS (and patch the drivers if in Windows 10).
Very little risk you're going to mess things up if you're just editing the BIOS you got from the card.

Hi, I have 4x rx470 8gb on Asrock Pro BTC 2.0 with EVGA1200PS and using risers and windows 10. I modded bios by altering 1625,1750,2000 values with 1500. Using Claymore 8.0, i'm getting 28MH per card at start and then dropping on 2 cards between 20-24! I changed location of rizers on the mobo and same result. 1- what did I miss? 2- how to undervolt without using wattman or trixx (modded bios maybe)?
Edit: AMD driver 16.11.5
Try 16.9.1. what is the memory type of your cards, Samsung, Hynix, Elpida ? Undervolting with trixx is very easy.. set -mV to -100, -120 or even -150.. 1150 or 1130 gpu clock and 2100 memory clock, if it freeze then lower down with memory clock.
Just to be really clear, with all of the cards to get the best performance you want to undervolt the whole chip, reduce the core clock slightly but raise the memory frequency as high as possible? I've been doing a normal and full overclock which is to raise all values slight and had poor performance. This is good as I will now focus on the memory overclock
Try a different version of Polar BIOS editor - I also had this issue but mine was with 1.2 showing values like you have. After running 1.4 my issue was fixed.
Went here to find out stuff I don't know yet but saw a massive list of questions from miners that doesn't know squat about BIOS editing nor flashing GPUs.

I have RX 470 Sapphire Nitro 4G (no+) with Hynix memory and i can go as high as 28.8 without any errors or mining stops.
Here is image:
Temperature is ok, Fan speed is ok, but how to tell that GPU is not "overclocked" or set high values? There is no overheating also.
Also, how to use underwolt options correct? When i lower CoreClock power usage goes down. Is that enough or correct option for "underwolt"?
My ring have
Motherboard Bios pro TB-250
8 gb ram
Power 1300 w gold
I5 intel prossesor
Win10 pro . 64 bit
Rithg now each is 24 mh/s . But i would like to up.
Anyone can tell me please ??
Is it that huge difference with stock?

But Radeon seems to perform better i read.

I'd try editor 1.2 and see how you get on
"Flash the BIOS (and patch the drivers if in Windows 10)."
I have flashed my cards BIOS but I have done nothing to the drivers in Windows 10. Wasn't aware you needed to patch them in any way?
Just simply run once downloaded.
