Best BIOS ROM for Sapphire RX 470 8GB Mining Edition with Samsung Memory 29 – 30 MH/s

Ledger Wallet protects your bitcoins

Hello and welcome to my tutorial on how to make a Sapphire RX 470 8GB Mining Edition (ME) hash 29 – 30 MH/s. I have reviewed the card some time ago – you can click here to know more about the specs, pricing and other aspects of the card.

This is my first BIOS and mining performance test of a mining edition GPU.

I’m really excited about this guide because I have found the exact steps on how to make the card hash properly and I will be sharing all of them with you right now.

If you liked this guide, you might also be interested in my 570 8GB mining edition GPU one. I will be posting it soon, so stay tuned.

What You Will Find In This Guide

Do you have trouble configuring your Sapphire RX 470 8GB ME? Do you feel depressed because your card fails to hash properly? Are you considering selling it because it simply refuses to work? I know how you feel. Luckily enough, I have discovered the needed steps to make my Sapphire hash normally. It took me a lot of research and trial and error; I have made this tutorial so you don’t have to reinvent the wheel.

The trick is to find the right BIOS version and spice it up with the right clocks. I have managed to make hash properly each of my four Sapphire RX 470 8GB ME. Hashrate is stable so far, as well as power consumption.

Before we start with the guide, I’d want to mention that Sapphire RX 470 8GB ME have some sort of design issue that makes them hard to set up for mining. Since other people are apparently facing the same exact problems, I’ve thought that I’d start this guide with some troubleshooting.

If you are like me, you will encounter one or more of the following bugs along the way. Therefore, I thought it would be a good idea to inform you on the potential problems you might face and provide you with the adequate solutions.

Note: The Sapphire RX 470 8GB Mining Edition I am using have Samsung memory – this bios wont work with Hynix memory chip manufacturer.

Problems and Fixes

I will update this list with more problems and solutions soon.

  • GPU not recognized by atiflash
    1. Uninstall drivers with latest version of DDU in safe mode.
    2. Install latest mining edition drivers
    3. Download latest Atiflash 2.77 and try again
    4. Also try to backup via CMD and apply the patch
  • Exclamation mark in device manager after rig reboot
    1. Apply the patch and restart
  • Flashing BIOS error message
    1. If you get that while trying to flash the bios via atiflash gui, try again via CMD with –f –p
    2. If you still get the same error message switch BIOS jumpers to the other side and try again (you can do it without restarting the rig)
  • Empty Backup BIOS – 0 KB BIOS Size
    1. For some reason, the silent BIOS version that was saved by atiflash resulted in a 0 KB file. I was able to backup it with GPUz and getting a full-sized back-up with a size of 256 KB. You can also try to backup via CMD using –s command (I missed that)
  • Claymore no AMD or CUDA GPU detected
    1. Apply the patch and restart the rig

The BIOS

As you already know, the card offers 4 BIOS versions to choose from (Quad UEFI BIOS). Here is how this works, according to the manufacturer:

  • BIOS #1 (default mode) has the maximum performance
  • BIOS #2 is called ‘Efficiency’ and in theory it should make the GPU consume less power and consequently output lower hashrate
  • BIOS #3 and #4 another two BIOS set like the efficiency one.

I have tried all of them and I wasn’t able to get more than 27 MH/s. In fact, there were times I was getting only 23 MH/s. Yeah, I know… you can express your condolences in the comment section. Fun fact is that power consumption always remains the same, no matter which one of the four BIOSes you choose.

Stock BIOS Hashrate Performance
  • BIOS #1: 27 Mh/s (download)
  • BIOS #2: 24 Mh/s (download)
  • BIOS #3: 27 Mh/s (download)
  • BIOS #4: Error :/ (download)

How to Make the Rig Work without the GPU Display Adapter

Mining edition GPUs come with no display adapters to reduce costs. In on order to have an image on your monitor, you’ll have to connect an HDMI cable directly to the motherboard. Then, you’ll have to do a couple BIOS modifications and you’re set. Let’s review the steps in detail:

(In my case, I am using an AsRock H81 PRO BTC R2.0)

  • Access Motherboard BIOS
  • Go to Advanced tab, then Chipset Configuration
  • On Primary Graphics Adapter choose “Onboard
  • Save changes and exit
  • Now you are able to have display via the motherboard. The thing is that if you open MSI Afterburner, you will notice that “Core Voltage (mV)” is frozen and cannot be changed. Here’s what you do to fix that:
  • First make sure MSI Afterburner is closed; go to “Device manager”, dropdown Display Adapters, right click on “Microsoft Basic Display Adapter” and disable it. Now, start MSI Afterburner; if you still see the voltage frozen then you probably forgot to unlock it in the settings. Simply go to Settings -> General tab and check “Unlock Voltage Control” and “Unlock Voltage Monitoring” boxes.
  • That’s it; now let’s move on to the next steps
Flashing the BIOS

Since this card has two BIOS switches with 4 BIOS versions, I had to test each of them to achieve the best results. If you try each of the versions on default settings, you will not achieve more than 28 MH/s. You can test it on your own if you want to.

This is why we have to flash it to achieve better results. Important Note: I have modded the Efficiency Setting BIOS. This means that before flashing it you will have to toggle both bios switches down and restart the rig

1 Back Up the BIOS

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

Sapphire RX 470 8GB Mining Edition – Mining Performance Stock Clocks (Samsung Memory)

System power draw is 50W

 

RX 470 8GB Mining Edition Ethereum (Ethash) Mining Hashrate Performance & Power Consumption

Ethereum Only

Same settings can be applied and the results will be the same if you want to mine any coin that runs on Ethash Algorithm like Ethereum Classic (ETC), Ubiq (UBQ), Expanse (EXP), Soilcoin (SOIL) etc..

start.bat file for Ethereum only with claymore clocks and voltage: EthDcrMiner64.exe -epool eu1.ethermine.org:4444 -ewal ETHEREUM_WALLET.WORKER_NAME -epsw x -tstop 85 -tt 65 -fanmin 75 -fanmax 100 -cclock 1150 -mclock 2150 -cvddc 850 -mvddc 875 –dcri 5

 

Ethereum Dual Mining Decred and Siacoin

I only used .bat commands to overclock the cards

Ethereum 29.950 Mh/s – Decred 630 Mh/s

Ethereum 28.200 MH/s – Siacoin 400 Mh/s

start.bat file for ethereum dual decred with claymore clocks and voltage: EthDcrMiner64.exe -epool eu1.ethermine.org:4444 -ewal ETHEREUM_WALLET.WORKER_NAME -epsw x -dpool dcr.suprnova.cc:3252 -dwal SUPRNOVA_USER.WORKER_NAME -dpsw WORKER_PASS -tstop 85 -tt 65 -fanmin 75 -fanmax 100 -cclock 1130 -mclock 2150 -cvddc 850 -mvddc 875 -dcri 5

RX 470 8GB Mining Edition ZCash (Equihash) Mining Hashrate Performance & Power Consumption

You get the same results and power consumption for the following coins running on Equihash algorithm: Zencash (ZEN), Zclassic (ZCL), Hush (HUSH), Komodo (KMD)

Download and extract Claymore ZCash Miner: https://bitcointalk.org/index.php?topic=1670733.0

Claymore Miner ZCash Hashrate 278 H/s – 300 H/s

The bios is not really optmized for ZCash, maybe i will work something soon..

RX 470 8GB Mining Edition Monero (CryptoNight) Mining Hashrate Performance & Power Consumption

Once again, the same procedure can be applied to mine CryptoNight Algorithm coins like Karbowanec (KRB), Bytecoin (BCN), Sumokoin (SUMO), DigitalNote (XDN)

Download and extract Claymore’s CryptoNote GPU Miner: https://mega.co.nz/#F!e4JVEAIJ!l1iF4z10fMyJzY5-LnyC2A

In this case, for some reason I wasn’t able to set the clocks via .bat file and I had to split the commands. I set the clocks to 1130/2150, undervolted the GPU to -100mV via MSI Afterburner and added –mvddc 900 to the .bat file.

MSI Afterburne / Claymore 760 H/s

start.bat file for Monero (XMR): ZecMiner64.exe -zpool eu1-zcash.flypool.org:3333 -zwal ZCASH_WALLET.WORKER_NAME.WORKER_NEM -zpsw x -tstop 85 -tt 65 -fanmin 75 -fanmax 100 -cclock 1130 -mclock 2150 -cvddc 850 -mvddc 875

    • No, ill post tomorrow the one for hynix memory

      • Robert Gzivna

        hello, im waiting for the bios 🙂 still working on it? im looking for custom straps as i already copy paste 1500-2000, but want more:)
        also samsung 4gb version will be good too

    • Mark

      +1 – thanks Ciprian!

      • still working on it 🙂 bios ready.. will post the article later

  • Odina Uchiha

    or better buy some rx 470 4 gb minning ver? the price is about 70-80 usd lower? l saw 2 version on eshop rx 470 8gb mining , but the price is different ,1 is cost about 375 usd and the second is 345 $ ,( same parameter) maybe the first 1 is samsung memory?

  • Ed Stewart

    Is this only good for the ME version? I have Nitro+ 8gb Samsung memory but sounds like this won’t work?

    • I guess it should work with the Nitro+ too.. because i combined the timings from this card 🙂 give it a try and let me know.

  • Rodolfo Mattei

    can u pls do with 4gb mining edition with hynix memory ????

  • Erik Lensherr

    Hi there, any news for Hynix bios? For me 1500 straps to 1750, 2000, doesn’t do miracle:(

    • working on it.. will be posted tomorrow..

      • Erik Lensherr

        You are the best!

  • andika cahya

    can i apply this with my RX 470 4gb power color mining edition elpida memory?

    • nope.

      • andika cahya

        is there any how that you make tutorial for that as well? many thanks

      • andika cahya

        can you do teamviewer for my cards? i have problem with the power draw. my 470 hynix gaming edition only 60-65 in gpuz. but this new 470 elpida mining edition brown box draw like 80-85 in gpuz. and its already undervolt use MSI AB.

  • Roberto

    You write some very good and detailed articles! Very informative. Kudos!

    Do you also have plans to create such a guide for the Sapphire RX470 4GB Mining Edition cards? I have the Elpida (7x) and Hynix (2x) versions. I have seen them do 30Mh but couldn’t get them stable (also because of insufficient time).

  • Alex

    Thanks for the article, really good and did bump up my hashrate to ~25Mh, any idea how i can get the remaining 5Mh? I think the only difference between my setup and yours is the mobo and that i’m using EthMiner to mine, not Claymore.

  • bezo

    hey, I have a msi armor oc rx 470 8gb samsung , I tried changing the straps and it doesnt work. any advice on it ? currently getting 20 to 21 mhs.

    • what memory ?

      • bezo

        Samsung memory

        • what straps have you copied? can you send me both original and modified bios versions?

  • Luis Liao

    Hi Ciprian, there are 2 Modded Bios file to download, V1 and V2. Whats the difference between the two Bios???

    • Go with the first one, both should do the same, v2 can consume a little bit more than v1.

  • Pavel Isaenkov

    On my Sapphire RX 470 8GB Mining Edition your BIOS did not work. A map in the device manager with a yellow exclamation point. What could be the problem?
    How did you set the timings? At what frequency did you copy the values?

    Found a solution: Apply ATImdag Patcher.
    Got 27.6Mh without MSI Afterburner and Claymore tuning.
    The result of ZEC is better on the stock BIOS – 284 hash.
    Thank you for the article

    • Also don’t forget to lower dcri to reach 29+ mh/s when mining ethereum with claymore 🙂

      • Pavel Isaenkov

        With your BIOS version1 (version2 did not try) began to appear an incorrect share with or without Claymore settings. It is possible to somehow fix it? or is this normal?

        • hmm.. strange.. i didn’t had that problem :/ have you tried to lower mem clock ?

  • Eshko

    Hello Ciprian,
    I have 6x Sapphire Rx 470 8GB Nitro+ and 3x Sapphire Rx 480 8GB Nitro+ all with Samsung memory.
    What is your advice for best performance on undervolting and overclocking these cards? Can I use this tutorial on them? Thank you for all your help.

  • Pavel Isaenkov

    Hello!
    How to fix incorrect share?
    A line appears:
    GPU # 1 got the incorrect share. If you see this warning often, make sure you did not overclock it too much!

    • Abo Mourad

      are you fix it same problem to me

  • Abo Mourad

    good but my hash rate 27 only eth

    • lowered dcri ?

      • Abo Mourad

        thanks can you help me at rx460 bois plz

  • Abo Mourad

    when i set memory clock to 2150 error make sure you did not make overclock to match
    how can i solve
