Best BIOS ROM for Sapphire RX 470 8GB Mining Edition with Hynix Memory 30+ MH/s

Ledger Wallet protects your bitcoins

Here it is guys, as promised! Just finished to test Sapphire RX 470 8GB Mining Edition Hynix Memory, great performance just like the one with Samsung memory. In this benchmark i included LBRY and Pascalcoin and PascalLite for dual mining, i kinda avoided them lately but someone asked for them.

Firstly the GPU was tested remotely but later i got one from a friend, again power consumption will not be that accurate because i “LOST” the energy meter :/, we will compare it with the previous one.

Apparently the RX 470 8GB Mining Edition with Hynix memory is less problematic, so this time i wont have a “problems and fixes” section.

The BIOS

I discussed and explained how to use the QUAD UEFI BIOS switch jumpers in my previous tutorial for mining editon gpus, another thing you can find is a quick guide about to make the rig work without the GPU display adapter.

Flashing the BIOS
1 Back Up the BIOS

Before flashing the new BIOS, I recommend you to back up the original one first.

  • If you don’t know how to do it follow point 2 from my previous tutorial: click here

3 Flashing

VERY IMPORTANT: Always extract ATIflash to C:/atiflash folder and place the ROM file that needs to be flashed in the same directory

If you need help, follow point 5 from my previous tutorial or check the following video: click here

  • Fred234

    Thanks for the hard work and the information! I did not buy any AMD’s because of the Hynix memory, now I shall look for some cards. I read that all new 1060’s are now Hynix memory, not sure if this is true tho.

  • Dragos- Corneliu Serban

    Nice job figuring this out! I’ve been trying to get these cards to perform for a few weeks now, and was only getting 25mh/s. Let’s see how they’ll pass the test of time. Thanks for sharing your work & results!

    BTW – I’ve just updated to Afterburner beta 16 and can’t seem to activate the core voltage. Any suggestions?

    • Have you disabled on board video card from device manager? Also have you enabled the voltage from afterburner settings?

  • Thomas Lendl

    great work!!!! do you have a bios for the rx 470 8GB mining edition with micron memory?

  • Jakša Ćosić

    Does anyone have moded bios for Sapphire RX470 4Gb ME with Elpida ram?
    I need the bios that has been modified voltage directly in the bios since i need to use it on simpelmining os and the undervolting doesnt really works with this card.
    Thanks

    • I just finished to test the 4GB ME with Hynix memory, the one Elpida mem will be tested soon.

      • Jakša Ćosić

        Ok, great, on some gpus hyinix and elpida share same bios maybe here is the same on this card but i am not sure, are you able to integrate low voltage settings directly into the bios itself? thanks

      • Lucas Rodrigues

        I’m waiting for it my friend. I also have built a rig with 6x RX470 4GB ME with Elpida memory. It’s not good soo far without your roms.

  • Rodolfo Mattei

    Very Nice man…do u think this set up work with ethOS?

  • Banex

    When I put both Bios switches down (hynix) and restart rig windows not recognized card? Should I reinstall driver or there another fix?

    • Banex

      atikmdag-patcher solved the problem. Now i raise from 21.5 to 24.5Mh/s. Improvement 🙂 Thx

  • Nopi

    I did everything in order as you wrote down but the speed only increased from 20MH/s to 22MH/s. I tested all switch positions and one time I got 24MH/s but after a restart it dropped down to 22MH/s again. What did I do wrong?

    • Dwayne Clarke

      I am having the same issues. Stuck at 24 MH/s with updated BIOS and miner. bat file setting did not do anything. I think the DAG increase to #150 is causing AMD’s to decrease in hashrate.

    • Have you tried to lower -dcri ?

  • henyojess

    Hi Ciprian V.

    Any chance you can share a good mining bios for Gigabyte RX580 8gb(hynix H5GC8H24MJ)

    https://www.gigabyte.com/Graphics-Card/GV-RX580AORUS-8GD-rev-10-11#kf

    • I dont have a bios for this card.. but i can connect to your rig and make one 🙂

  • Luthfi Zain

    Sorry for my stupid question, but this BIOS will only work for this particular type of GPU right? I mean different brand, different mem chip will need different BIOS, and you can make the BIOS for them. Correct me if I’m wrong.
