Custom R9 380 BIOS for 23-24Mh/s

[dmwardjr]

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.

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

Sure, you're very very very welcome.  PERFECT

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.

Hey guys.
After flashing my Sapphire AMD 380 i still get only 17-18 hash on windows.
Any solutions?

Secure boot is deactived and MSM activated.

Read the post #131 from dmwardjr. I got all my cards increased from 17 to 20.xx with his post using stock setting

[jeffo91]

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?

[jeffo91]

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)
Thanks in advance.

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
