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

  • 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.

    • Umer

      What is wrong with Hynix? I have RX570 Hynix and I am getting about 30Mh/s at 100W!

      • Fred234

        I know Nvidia cards with Hynix perform 20% less than Micron or Samsung memory. Good to hear that AMD cards are not having that issue.

  • 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?

  • JakΕ‘a Δ†osiΔ‡

    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.

      • JakΕ‘a Δ†osiΔ‡

        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 πŸ™‚ 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 πŸ™‚

  • 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.

  • mr B B

    Thanx for the awesome tutorial,
    question:
    -Whats normal working temperature of this setup? 55-65 celsius?

  • Andreas Gallios

    Hello and thank you for the work,im on these cards win10 blockchain drivers i flashed the bios i got around 24mh but i cant overclock them with afterburner nor with claymore,when i set the memory clock nothing changes.any suggestion?

  • daniel jackson

    I cant get over 25m/h with this bios. i cant add the commands into claymores because i have 3 different GPU in the same rig. any ideas?

    • You will have to add the commands for each gpu separated by comma πŸ™‚

  • strelly

    Hi Ciprian, I’ve a Sapphire RX 470 OC 4Gb (reference) with Elpida RAM…could you tell me where I can find a good BIOS mod? my performance is max 20 mh/s with claymore dual miner πŸ™

  • Abo Mourad

    nice jop but i have problem i make same steps i have rig 8 card asrock h110 i reach 30 mg/h every card i use claymore and lower dcri 4 when restart rig it back to 24 mg/h
    and told me( Default Radeon wattman settings have been restored due to an unexpected) and when i turn off claymore and open again rig restart i use afterburner beta16 same problem

  • Umer

    Anyone know how to disable ‘Fan Stop’ feature on this card?
    I have fan set to manual and maxed out in WattMan. The fan revs to 100% but stops to 0 every few minutes.
    I can seem to disable fan stop completely! Please advice.

  • Mos Ioan-Corneliu

    Hi,
    Have you a BIOS for Sapphire RX 570 8GB ME with Hynix mem?
    Thank you.

  • Jason Antony

    Hi, do you think the rx 470 mining edition will decrease its hashrate the same as the normal rx 470 cards as you wrote in one of your articles a few months ago in June? And do you think it is worth it to buy the mining edition, given that it has no display output and smaller warranty?
    What are your thoughts on that?

    Thanks a lot in advance.

    • That problem was already fixed with the new driver release πŸ™‚

  • Bart Hajnas

    Hi Great tutorial, what settings would you recommend for simple-mining os?

    • I didn’t tried SMOS yet, maybe i will make a tutorial soon..

  • dcving1two3

    Thank you for all of your hard work in putting this together for us! I have the Sapphire rx 470 4GB mining edition. The sku # is 11256-35-21G. Will this tutorial apply to me even tho you are running the 8GB version?

    • For 4GB version BIOS is different, planning to post today the article for those..

      • Dcving1

        Were you able to make the article for my specific model of 470? I just finished my build with the 4GB mining editions and I dont want to screw this up. Do you have a link to it?

        • not yet πŸ™ sorry.. i promise i will have it posted this coming week..

          • dcving1two3

            Ok well, I don’t mind throwing you a tip for your efforts. I just gotta build my rig tomorrow. I’ll try and figure something out. Thanks again

  • Denis Januzi

    I can confirm proudly that Capriani did it again!!! its working great and hash is 181 with 6 cards i used all his tutorials maybe few changes so far great performance

    big thanks Capriani

    • Awesome, thank you too @denisjanuzi:disqus πŸ™‚
