hello. I am a newbie with mining. I have three R9 380x 4Gb (1 Gigabyte, 1 Powercolor PCS+, and 1 MSI) but only got 17.3 MH/s for each card using stock setting.

My first question: which driver version should I use to get 20+ mh/s? I am using Windows 10 Pro.

I still have 78 x R9 380's along with the rest of my other cards (old and new).  You should be getting 20 MH/s each card STOCK.

You need to use a DDU to UNINSTALL your current DISPLAY DRIVER (DDU) in your 380's.  Then install the Blockchain Driver.

Here's an excellent video for doing what I suggest:  https://www.youtube.com/watch?v=EXLahUxmTOI&t=672s

Thank you million million times. I got 20+ on all of them now.

Sure, you're very very very welcome.  PERFECT  Smiley

Hello fellow miners...

Tomorrow i want to atiflash my AMD 380 so i have a few question on the topic.

1) How can i check (withouth danger to kill my GPU) that the card could handle the "380NR1100" Bios with 100mV undervolting? Can i check it before with Programms like TRIXX?
Otherwise i would go the safe course and use the "380NR1150" BIOS.

2) If i open the Custom ROM with PolarisBiosEditor i get a error message. Is this normal with already edited BIOS? ( Something that the index it out of the the array)

3) I have 6x R9 380 GPU´s. All from a different manufacturer. Can i upload the custom bios on all of them without danger?

4) Do i need to install the blockchain driver on simplemining?


Thank you !

I'll answer the question that I know

2- You won't be able to open the file with Polaris Bios Editor because it isn't a Polaris BIOS file. It's Tahiti (or Tonga, Or some that island that I don't know). You can try Hawaii Bios Editor

3- Danger is around us. Every different model is a chance to "swipe" memories in a different order than Nerdraph's bios.

4- No. The R9 cards doesn't take any effect from Blockchain driver or the lastest driver's Compute Mode. It only affects Polaris cards. Because this, R9 cards suffers a lot from DAG size increase.

Well i used the ROMS from OP and tried to install blockchain drivers. For a few moments i had 21+ Hash.
After that my windows crashed an i couldnt mine anymore... so i changed to simplemining again and had 17-18 hash ...

How do it get this hashrate on simplemining? Is it possible? Or on any other OS?

Does someone have the original ROM for me maybe? I want to flash the cards back and deleted my backup by misstake.

Want to sell the cards. They are not worth it.(Cant get them over 19 hash)

Hi dmwardjr,

I am now working on flashing. I wonder what settings I should use for the following cards for lowest power consumption. At stock setting, they are using 190-200W each. It's pretty high for me. I'm ok with 20.5Mh using stock setting but wanted lower power consumption.

Gigabyte 4Gb _ Hynix
Powercolor 4Gb_Elpida
XFX 4Gb_Elpida

I also could not find a modded Bios for my Gigabyte card on Anorak. If you have, please share.

Thanks.

I still have stock BIOS in my 380's.  I'm going to use AMD Global Wattman settings to make an ATTEMPT at better power efficiency once my mining room remodel is completed:  https://bitcointalk.org/index.php?topic=2865914.100
