In this thread i want to explain how i build a 7x RX 570 mining rig step by step, but as you may know, there's an issue with the driver, and in the moment i plug a 5th GPU, windows doesnt work in the way it should, the same in simpleminingOS and ethOS. I must say that 4 GPU are working good, here you have some pics of my rig and a list:

.PSU: EVGA G2 1600W
.VGA: SASPHIRE RX 570 PULSE 4GB
.VGA DRIVER: 17.4.3
.MOBO: MSI Z170A PRO CARBON
.MOBO BIOS VERSION: 1.81 Creepas MOD
.CPU: INTEL PENTIUM G4400 SKYLAKE
.HDD: SAMSUNG 120 GB SSD
.RAM: 4GB CORSAIR

. Driver 17.4.3 not working
. Driver 17.4.4(Beta) not working
. Ethos with more than 4 GPUs not working
.Simple mining os with more than 4 GPUs not working

My bios settings:

.4G decoding on
. PEG0 and PEG1 GEN 1 and GEN2 not working

I just want you guys to help me to fix the issue with 570/580 and i will write a guide step by step, tomorrow i will try to flash a modified BIOS that will try windows to recognize 570 as a 470, then i will be able to use 7 570 with the 470 driver

thanks @creepas for your support, this is his post:

UPDATE 1:


this works guys! we have 5 working GPUs

I personaly think that the only way now is to flash RX 570 to RX 470 i see no other way. I hope we can try it tomorow.

cReepas

Hello,

I have 5 XFX RX 580 GPU on same configuration working normal, after plux sixth card windows dont boot.

4G decoding on
GEN1 set up

I install 5 cards fist
plug sixth
windows boot normaly
after driver automatic installation blue screen : Driver try to rewrite memory of system (something like that)
after that i cant boot too.

I heard flashing the 570 cards to 470 (Force flash option in atiflash)

Good thing you opened a thread about this problem so we can solve it.

Already had 2 frames ready for 12x570, i now made one more so i can run 4 cards per frame heh.

I will try to help in resolving this issue, we realy don't want 4gpu rigs when we can have 6 or more  ;D

Did you try flashing them to 470 bioses?

The same issue on Gygabyte Z170 Gaming K3 and 6 cards Aorus RX570 4gb.
Windows 10 is working good with only 5 and with 6th is reseting.

All checked
- other risers - not work
- other power suply - not work
- other (same) mMotherboard - not work
- other 6 cards - not work.

 Did any of You overcome the problem?

No, i'm trying it this evening and i'll write how does it work, but guys, you better think un other way to solve the issue becouse maybe it doesnt work, whatever you think that mayor work, tell me

i have try it with msi gaming motherboard with 7gpu rx 470, but its very hard to get 7vga running all, now im using only 6vga.
i think better we mining with simple setting, so we not wasting our time to build mining farm

i think you must check your pcie setting, set the pcie to x1 x2 x3 or auto (find the best) then you can disable wlan too at bios, disable onboard vga

I think that at this moment nobody did it, but pay attention to this threat, we all can fin together the solution

Yes. My team is working with You!

We will give a try this evening, so be atempt to read this post later, maybe we have fixed the problem :)

Let me know. I also solve the problem. My solution is 5x 570 + 2x 1060 gtx for now. :) 5x29MHs + 2x 23.5 MHs per rig, works fine.

Great Amigo! Lets Fight wit it and Win! :) ;D

How did you get it? When we install 5x 570 it works fine, but if we reboot, sometimes it works, sometimes windows reports error 43, it isn't stable.

In ethOS or simpleminingOS, we need to activate 4g decoding to use more than 4 GPUs but it fails and it doesn't boot

the only thing we can do is to disable wlan, we cant do the other settings in this mboard

Yes after the first or second restart again 43. I will restore the patch and immediately new patch application. Then everything works fine. Now I've done 3 restarts behind and it's still working.

I tried and you were right :)

Guys - lets try to do it if You can (I can't test it because I'm right now out of my working place next 3 days...

SOLUTION from BuriedOne: Well that sometimes happens as cause of the drivers, but try to install them in this way: uninstall all drivers for the cards with amd clean install, after that add two cards and install the driver. After that, pull out all cards and add the next two, start it up and wait for the drivers to install automaticaly (it will flash the screen for about 5 minutes). Repeat this for the next two, after that turn it off and add all cards. This should work! :D

Please check it all and write if its helped!

ok Im trying

Fingers Crossed!  ;D

not working :(

Nope, instant crash and reboot :(

We need to know first how to mod RX 5XX cards.

Does anyone has some way?

Do you mean bios mod for 570 or how to flash 570 -> 470?

how to flash

Yess. Mayby is the resolution for now to fash only 6th card in a rigs to 470 and start to work and then looking for more elegant way?

no doubt about

smOS has has a few test builds out now to try to fix the 4g decode issue with the z170 and z270 boards. Might be worth trying those out.

For atiwinflash:
> atiwinflash -p 0 -f Elesmere470.rom

Use cards that are very similar in design, for example asus strix 470 -> asus strix 570.
To be honest i have no idea if card flashed like that will work properly. On the other side, if you can flash 470 with 570 bios, then 570 with 470 should be possible too.
<fingers crossed>

Don't forget to run Atiwinflash in command line with Administrator rights

It is not possible to flash it with atiwinflash because it doesn't recognize the RX 570, I already tried it :(

Atiwinflash doesn't recognize the 570 :(

Weird, yesterday i flashed a few rx570 with custom bios and it worked just fine. Do you use command line or gui?

I did both, but maybe I made a mistake in some step, I don't know, could you please show me how did you flash your modified BIOS? And maybe this is a lot to ask but, could I have your modified BIOS if it works good? Does it solve the driver's issue that doesn't allow to use more than 5 Rx 570?

Thank you in advance

Ok, i will post a simple way, step by step, maybe someone will find it usefull:
0. Download atiflash ( https://www.techpowerup.com/download/ati-atiflash/ )
1. Use latest gpuz to import bios ( https://www.techpowerup.com/gpuz/ )
2. Use SRB Polaris Bios Editor to open bios ( https://bitcointalk.org/index.php?topic=1882656.0 )
3. Change voltages, frequencies, copy straps, whatever you like. Strap modifier is nice tool, just paste your strap (1750) into the the addres and it will be modified -> http://doreymills.ca/cgi-bin/strapmod?555000000000000022CC1C00AD515A3EC0570E142D4A64080049C700030114207A8900A00300000%3Cspan%20style= (thx Ralph). Paste strap into 2000 field.
4. Save it.
5. Paste atiflash_274 folder into C:\ and put modified rom into it.
6. Press Windows key -> cmd -> run as admin -> cd.. -> enter -> cd.. -> enter -> cd atiflash_274 -> enter -> atiwinflash -i -> enter (it will shoe you your cards) ->  atiwinflash -p 0 ElesmereMod.rom -> enter
7. ???
8. Profit!


It doesn't solve driver's issue.

Thats why we want to test to downgrade the card to RX 470. But we are unable to use the atiwinflash as it says no adapter found.

I hope it gets fixed fast though. I have 6 coming in tomorrow.

driver limitation of the rx 500series can't do 6 or more gpu yet

I noticed this today, i can get to work only 5 of 6, 570GPU with the latest AMD driver.
I think i will flash to 470 vendor and stay using  17.1.1 relive.

There was no error, windows just rebooted after all gpus stopped. (so the windows loaded it, after instant reboot )

Great idea! Please flash 1 card of 6 and try.
If it will work - tell us how You did it.

Just flashed 570 with 470 bios. It was successfull, but i can't install pre 17.4.3 drivers. 17.4.3 can be installed, but after that card is still recognized as rx570. Probably hardware id realted issue.

Long story short: NOPE

Hello,

asi its possible to flash RX 470 to be seen as 570 i dont think you are right.

cReepas

Is the 5 card ok but the 6 card wont boot a Windows only thing? or has someone ran 6 in Linux yet?

Maybe it depends on card model. I tried with asus strix oc 4gb elpida memory.



Linux is fine, 6 rx570 with no problem.

If Linux supports 6 cards on the same hardware - its 100% Windows and drivers problem. We need some HOT FIX :)

I see talk about 570, anyone have word on getting 6 rx580s to work on either win10 or Ubuntu?

What linux? And do you know if it would do 7 cards? Windows is definitely out until AMD gets a better driver. Best I can do is 5 cards. Windows recognizes all 7 RX580 until I install that damn AMD driver then it won't load. Unless, I remove two of the cards.

Hello here is a guy that make work 6x 580 4gb on linux. He explain it.
https://www.youtube.com/watch?v=5Di8Jid4eo4
 ;)

Hey guys, I've already done a lot of this so let me give some info I learned.

Alright first off, for Z170 and Z270 chipsets, I found that the best way to get the 5th card working is to DISABLE memory encoding, install one graphics card at a time. If you're getting any code 43's on 4 cards, you need to regedit hack Windows "DisplayLessPolicy" and "LimitVideoPresentSources" (google). Once 4 work fine, install the 5th and reboot. Now you should be getting code 12's. NOW you go into BIOS and Enable 4G Encoding. Start Windows. 4 cards may work but one card might report problems. Disable this card in windows, wait 30 seconds, reenable it. It works. If you have older drivers, you're on your way to 6+ GPUs.

Now to those unlucky to have the RX500 series. The newest drivers have a bug which I've submitted a bug report for. Details of this bug can be found here: http://www.overclock.net/t/1604567/polaris-bios-editing-rx5xx-rx4xx/2740#post_26060006

In short, you can disable one of the 5 cards, install the 6th, and boot into Windows fine. Try to enable the last card though, NOEXECUTE BSOD.

However I want to go a bit further here. I was able to get 7 running perfectly fine under Ubuntu. Had to make sure everything was installed UEFI/GPT compatible and also for some reason GRUB bootloader doesn't work with 4G Encoding enabled, so I had to set up booting directly using the kernel's EFI stub loader (google). The reason why I got off Linux is power management, the cards wont accept BIOS voltage values lower than 987mV or so which is much too high for me, and there's no tool like AB to fix it.

Also to those wondering, I've tested flashing RX400 BIOS onto RX500 cards. Here's the weird thing, the cards are HAPPY to accept 400 BIOS. Under GPU-Z and AtiFlash it will show up as Polaris 10 architecture. They fully function and happily mine away. BUT the damn drivers STILL show them as RX580! You cant even get the older drivers to DETECT the backflashed cards! Can't force the 400 drivers on them either. This is a very strange result, because RX400 series can be flashed UP to RX500, and SHOW as RX500.

That's the result of my 3 days of grueling experimentation.

Well - That's a lot more information than I have now, thank you!!! Very much appreciated.

I may have to give unbuntu a try - the wattman tool on the 580's is being glitchy on the rx580's. Every time I make a change - even a fan change - it knocks a card out. Resets to default wattman settings. I have to reset and then one of my card gets the error. Then I disable/re-enable and it works fine. So any changes to voltage aren't working for me right now anyways. What a headache this has been. Not so happy with the 580's right now.

Thx for your tips.
I just order 4x 580 Nitro + LE.
I will try to make my first rig.
With 2x 480 Nitro + OC 8G that I'm using + the 4x 580.
I will build a wood case I think.

Disable Wattman and use MSI Afterburner instead. Much better results. Better control. Profiles. Tuning all cards simultaneously. Etc.



I used 580 Nitro+ LE's. They really arent that special for mining, I would have ordered the Nitro+ 570's instead myself had I known that. Difference seems to be 30.5 eth vs 29.5 eth.

Also I've worked with this guy on cases, he's pretty awesome, http://www.ebay.com/itm/New-4-15-17-6-GPU-Aluminum-Open-Air-Mining-Rig-Case-Ethereum-Zcash-Bitcoin-/182544436935?
Send him a PM, he'll accept cryptos, his default cases are built great and seat cards great, and for extra fee he can customize the case. Ships them quick too!

Thx for the answer I chose the 580 for dual mining Eth/Dcr.
And yes the case look great but finally I will try to use an Ikea wood shelf really cheap.
With your 580 LE do you get samsung ram ?

Yes, all 7 have Samsung. Used Uber-Mix 2.3 straps (See the big Polaris Bios Editing thread on another board, google). Uber-Mix 3.0 wasnt stable for me but others it works better

Thank You Very much for Your research.
In conclusion - we still have no solution for 6, 7 cards .. :(

Next tester have same problem: https://www.youtube.com/watch?v=MnMCST8Pgx4

I found out that its possible to mod the driver somehow? Maybe this is the way.

http://forums.guru3d.com/showthread.php?t=405134

?

what are the steps to get UEFI and finally get 7 running? is it enough to set like this in the installation?

https://i.imgur.com/8JK53Kl.png

it seems the issue is the combination of the driver and windows, when you try it in linux with more than 4 GPUs you have activate in the BIOS the option 4g decoding, then, when you try to boot the OS, it doesnt work, but it seems the problem is the the boot sistem, if you have an EFI system partition, it should work, we are going to try in 2 or 3 hours, we will keep you informed.

Is there a way to disable Wattman? I looked around and googled it, I don't see anyway to disable it. There seems to be some sort of conflict with the MSI Afterburner and Wattman. The MSI Wattman will only change one card - and the rest will get stuck at 300mhz. It doesn't matter whether it's synced or I try to change individually. At that point, Wattman will only let me manipulate one card and the rest grey out. As soon as I remove AB, profile and settings - everything is back to normal. Wattman will let me modify each card, but completely unstable. Even the smallest of changes such as fan control makes wattman crash, defaults back to regular settings. Then I usually have to reset. It's the same deal on 3 different rigs.

MSI Z170A PRO GAMING CARBON
MSI RX580

I got 2 rx570
1 rx580
2 rx480
1 rx470

And cant boot 6 gpu take code 43 error.

"If you're getting any code 43's on 4 cards, you need to regedit hack Windows "DisplayLessPolicy" and "LimitVideoPresentSources" (google)."

Will it work for me I get tired trying :(

Is it possible to combine rx 480 vs rx 570 in the same rig?

Hard to tell, just do it first lol it takes 10mins to do.

Also make sure your PCIe lanes are set to Gen1, that can cause Code 43 sometimes. If youve done all that, disable the 43'ing card, wait, and re-enable it.
Just reinstall the drivers after using DDU and don't accept the Wattman warning. Also the "get stuck at 300mhz" is a sign of ULPS mode, use AB to disable ULPS
Use Ubuntu Server v 16.04 LTS if you want to get it working. Set BIOS to UEFI Only and let the installer handle partitioning. I also recommend NOT using LVM when partitioning, just use the whole disk without LVM (its an install option). You should get a prompt to force UEFI installation during the process as well.

Thanks I tried windows dont work gonna try ubuntu

So no fix for windows yet?

Not until the drivers are fixed. The last drivers that work on Windows don't support RX580, and no one has been able to get RX580 backflashed to 480 to accept RX480 drivers yet.

---

Hope you got your kernel EFI stub booting working. I know it took me a full day. The instructions on this page work: https://wiki.debian.org/EFIStub just replace the Debian references to Ubuntu

Loving that DDU! Thank you - but the bad news is, it didn't work. Uninstalled the driver. Reinstalled it. Didn't accept the Wattman warning. Installed AB and disabled the ULPS. Same thing still happens. Tried it on two different machines and as soon as I try to make a change - it changes one card and the rest get stuck at 300mhz. Even the smallest of changes, it doesn't matter. Then I have to uninstall AB and profiles/settings - and they are back to normal.

Wondering if AB needs to come out with a new version to make it compatible with the RX580's or it's an AMD driver issue? Has anyone else been successful?

" Has anyone else been successful? "

NOPE :( WE WORKING ON IT....

"WE" ? Who is "WE"?

WE, community. WE on this topic and forum and WE all enginers in my company my friend :)

Look:

Solution is just around the corner.

AB 4.3.0 works perfectly fine on my RX 580's

Looks like he found a way i dont have any 5xx cards to test but sounds about right

I can confirm - it works!!!

I tested with BTC r2.0
AMD Remove Tool. -> Reboot
I used with 17.1.1 driver, I just put the oldest files to 17.4.4 \Packages\Drivers\Display\W76A_INF\B313057
Manual install driver, bios mod, ati pixel clock patch -> reboot.

6gpu 570 rig works as it should  8) ;)

Anyone know a WattTool alternative to RX 500?
Offset and Voltage options won't work. I can get 29.5Mh/s with claymore -mclock 2000

Without it only 25Mh after bios mod

https://i.imgur.com/TbjUbU7.png

Try msi afterburner or claymore to regulate mv

Yeah, like Sunstruck said - MSI AB or just do it manually in Claymore. After using Wattman for awhile, I think either of these options are better anyways. At least IMO. I found Wattman to be a frustrating experience, because I couldn't figure out how to sync my changes to all the cards. I had to manually input them to each card - and then when wattman reset to default settings do to some error - I had to re-input all the settings. Ug! Unless, someone knows something I don't? Which is very possible... :)

IS WORKING  - WE CONFIRM!

Hello All.
I was able to get 6 x RX-500 series running on windows 10 x64. After two days the stupidest thing I tried worked  Grin.
1. use DDU to clean the PC from any previous drivers.
2. Disable 4G decoding so you can log into windows (only  for Z170,H170, etc.)
3. Extract older driver for RX 400 series in Drive C: (I use 16.9.2 )
4. Extract driver for RX 500 series in Drive C: (I use 17.4.3)
5. Copy and replace all content from "C:\AMD\Non-WHQL-Win10-64Bit-Radeon-Software-Crimson-16.9.2-Sep21\Packages\Drivers\Display\WT6A_INF\B307117"  to "C:\AMD\WHQL-Win7-64Bit-Radeon-Software-Crimson-ReLive-17.4.3-Apr17\Packages\Drivers\Display\W76A_INF\B313057" (Basically you copy the old driver over the new)
6. Install the VGA cards manually from Device manager in Windows pointing path to the new driver 17.4.3 in this case.
7. Reboot and enable 4G Decoding in Bios
8. Enjoy if it works for you.

GREAT WORK antanas012 - is it Yours Masterpiece?

Confirmed aswell!

Wow guys you are the best!!!

what if i have an old motherboard asus maximus formula v? T_T mine still 5 gpus. 1gpu undetected

I`m glad my solution worked for all of you. ;D
I build rigs for my self and also for sale, so last week got a new order for 6 rig`s get all the components and start building it realizing the new RX500 series have driver issues and after two days start to wonder if i can modify the drivers by just replacing couple of files. I copied all off the driver just to check if the new ones accept the old DLL`s, CAB`s etc. files and it`s just happen to work  8).
So just got lucky this time around. ;D  

Lucky are not, you are the man. I was banging my head against the wall for days. Thank you so much!!!!!

Thanks a lot , wattman is useable with this solution ?

same with me
i'm using Biostar TB250 + 6xHIS IceQ 570 (elipda), but windows only detected 5 card :(

Unless your motherboard has "Enable 4G Decoding" or similar, that's going to be the case

In BIOS setting, I couldn't find 4G decode :((

Could someone please explain to me what is meant by
Install the VGA cards manually from Device manager in Windows pointing path to the new driver 17.4.3 in this case.?

I copied over the driver files, went into device manager, and re-installed the drive using the 17.4.3 directory. I still black screen if I used all 6.

im still trying also but maybe other term is "Memory Remap Feature" for old mobos

Update: mine is already enabled but still the same. and i can't find any that says 4G Decoding in ROG Bios of Maximus V Formula

I have an ASUS Maximus Formula V with 6 GPUs and it works with the above driver trick. You might need to look at your bios settings. If I remember correctly, I had to put Gen 2 on all three PCIE - and there is an option under those three PCIE's option that I can't quite remember what it was called. Something setup - I chose the first setup and gave it a try.

Its up and running and works great. So I know it's possible.

After you have uninstalled the drivers with DDU, restarted your machine and copied the files from folder B307117 into B313057 - You'll then go to the device manager. Choose one of the video cards and click on properties. Then go to the "driver" tab. Choose "update driver." You'll then choose "Browse my computer for driver software." Then navigate your way to C:\AMD\WHQL-Win7-64Bit-Radeon-Software-Crimson-ReLive-17.4.3-Apr17\Packages\Drivers\Display\WT6A_INF - Do not choose the folder B313057. You need to choose the folder WT6A_INF or whatever the folder is prior to B313057. Then hit next and it'll start the process. You will then get a prompt saying it does not recognize the publisher or something to that effect. Hit continue and it'll take a bit, but it will install the driver. Then restart your machine and you should be good to go.

However, you will not have the AMD radeon settings panel - You'll have to make modifications through MSI AB or claymore.

I already changed to Gen 2 for PCIEX16_1 and PCIEX_2
then the last one is Gen3 Preset which I changed to Preset 1. but still I don't get to detect the other gpu

Rig pr0n

http://i64.tinypic.com/k53hwk.jpg

What do you mean by "However, you will not have the AMD radeon settings panel - You'll have to make modifications through MSI AB or claymore."
I was able to get the 6 cards up and running on windows, but now claymore doesn't seem to want to work. It just "stops working" without any real error.

If watchdog is restarting the miner, scroll up a bit and see if any of the GPUs are hashing 0, means they died and you need to change your overclocks

 Trixx work for me undervolt Offset, but you have to apply one by one,
 Now I just put the values on claymore start (-cclock 1180 -mclock 2250 -mvddc 900 -cvddc 877) are my values and GPUZ show VDDC  0.8813V and 104W whit ETH+DCR
 I wll try change those values in polaris.

 good look

OMG!! what is the specs of your miner? mobo? psu? everything gonna copy it hahaha!

Meaning - you won't see the Radeon panel. The settings when you right click and see "radeon settings" or in the bottom right corner - see the little radeon icon. Any modifications such as overclocking, underclocking, overvolting or undervolting, you'll need to use MSI afterburner or do it in claymore itself.

Are you trying to overclock/underclock or adjust voltage? Do you have your 4g encode enabled for the boards that have it? Did you check the logs to see if there are any errors such as GPU 1 hangs in open cl?

Double checked my settings - and that's it. I have Gen 2, Gen 2, Gen 2 and then preset 1. You might double check your risers, power and or maybe even put it in a different slot. I do remember a slight delay when it recognized my card. I started it up, went to device manager and seen a line item that said unrecognized VGA device under something other than the display adapters. 2-3 minutes went by and then the screen flickered and it installed the driver and recognized all the cards.

You might also check your device manager to see if you see anything along those lines - unrecognized VGA device.

I'm assuming you have the most up to date bios too?

Windows 10?

No clue how you get those hashrates done. I read your other threads but my RX 580 dont even come close. I have them at 28mh/s - 362 mh/s  ??? with a bios mod and 1150 / 2150 settings on Trixx.

what is your bios? also yeah im using windows 10.
mine only shows two PCIE that I can put Gen 2. then Preset1 that's it. also which slots did you used? did you use all 3 red pcie slots?
laat, did you install card 1 by 1 or altogether? just want to be sure that im doing correctly thanks :)

I like what I see there! https://img.memesuper.com/9877a7d59f89541c16b10da3cbf496ff_house-bug-eye-bug-eyes-meme_500-500.jpeg



What motherboard are you using for 8 GPUs? Are you using a 1 to 3 PCI-E addon board?

I'm using BIOS 1903
I'm not using all 3 red pcie slots. I'm using the first 6 from top to bottom.
I did initially only use the first 2 red pcie slots to make sure it recognized the cards. Once I realized it recognized the cards - then I put all of them in there. I never installed the drivers at this point. I wanted to make sure that the mobo and windows recognized them. At that time, it was only 5 cards, because I experienced the issue with other rigs. Then I installed the driver 17.4.4. Ran, but was unstable. Kept get GPU 1 hangs in open cl errors.

Then once the driver trick came out - I DDU the AMD driver. Restarted my computer. Did the driver trick and restarted with 5 cards. I first wanted to make sure it was stable with just the 5 cards, because of the error in claymore I kept getting. Then about an hour later when I realized it was stable, I shut it down and inserted the 6th card. Started it - opened up the device manager right away. Seen the incompatible VGA card message. Then waited about 2-4 minutes and the system caught it. It installed the driver and the sixth card showed up.

But at this point - I think you should see if your machine will at least see all six cards without the drivers. No one had a problem with their mobo/windows seeing all six or seven cards without the drivers. It was as soon as the driver was installed that it would not boot if you had more than 5 cards. If your machine sees the cards - then I think you'll have no problem making it work.

On my bios - it says this. PCIEx16_1 - Gen 2, PCIEx16_2 - gen 2, PCIEx16_3 - gen 2 (but also says "not used," because I have nothing in this slot). Then lastly it says Gen3 preset - preset 1. I'm pretty sure that the gen 3 doesn't do much, but for consistency that's what I have it on and mine is working.

CPU - just in case is I5-3570 Ivy Bridge.

Hopefully this info helps you, but if it doesn't feel free to ask more questions. I'll help anyway I can. I know it works. I'm not pulling your leg, promise - I think it's just a matter of fiddling with it.



 

thanks for all the info. mine doesn't have the PCIEx16_3. hmm? i need to recheck the bios if updated. Later i will put more time on it just to make sure there's no fault in all the risers and gpus. i'm also thinking that i don't have to use the 3rd red pcie slot. but I did. later i will reinstall 1 by 1 all the gpu to make sure everything is detected. to sort out whats wrong. thanks man! :) i will update you once it works :)

btw, did you mod your bios for your 580s? also which brand you have? i got the XFX Black Edition GTS 8gb. left it mining eth then after an hour it freezes. im using now teamviewer so i cannot solve the problem.
i will visit my rig later XD

I think we all need that information. MOTHERBOARD? How did you get 8 PCI-E? SPECS?  ???

Lol I've said many a time that I'm using a Z270-A Pro with an addon board

Which addon board are you using?  I have been shopping around a bit.


Great work guys!  I have been pulling my hair out trying to get 5x570 work on ASRock H170A-X1.

I still haven't found the "4G Decoding in Bios" option.  Does anyone happen to know if this board/bios has the option.

Are you guys adjusting the TOLUD setting?  I know on my TB-250 I had to set it to 3.5.  If I set it to 3.5 with the H170A the PC will not display video.  It does work at 2.5 though.


Thanks again for this great information :)

Definitely, let me know if you get it running. Sounds like a good plan, motherboards can be finicky sometimes. I think one by one is probably a good call. Sometimes slower is faster. I haven't modded my bios yet. I'm newer to mining and while I have modded a bios before in my gaming days - I currently have this weird rules that until I get my ROI, I'm not going to take a chance to brick my video cards. I should have my investment covered in a few months. I have the MSI RX 580 Gaming X 8G. I got a good deal on them - so I went for it.

I have 4 gpu's in my rig (will try 5 when I get home).  The driver "trick" works perfect.

In addition to working fine -- I am no longer seeing high voltages on my cards.  Before they would go to 1.xx volt despite being set to 0.925 in the bios -- If I changed the clock speed in afterburner to 1150 then back to 1200 they would run at 0.925.

NOW they are using the voltage correctly.  I am also seeing a reduction of around 15w per card.

I did this, but i did it with windows 10 drivers and it didnt work. Then i noticed that you downloaded win 10 64bit 16.9.2 software and WINDOWS 7 64bit 17.4.3. Is that what I did wrong? I need to use 17.4.3 for windows 7????

Run DDU, uninstall everything.
Extract the 16.9.2 package and the 17.4.3 package.
Copy the contents of the B30##### folder from the 16.9.2 package into the B31##### folder of the 17.4.3 package. Confirm overwrite files.
Run the Setup.exe in the 17.4.3 package. Install AMD display drivers. Accept unsigned drivers.

Yes, that is what I did. however look at step 5


5. Copy and replace all content from "C:\AMD\Non-WHQL-Win10-64Bit-Radeon-Software-Crimson-16.9.2-Sep21\Packages\Drivers\Display\WT6A_INF\B307117"  to "C:\AMD\WHQL-Win7-64Bit-Radeon-Software-Crimson-ReLive-17.4.3-Apr17\Packages\Drivers\Display\W76A_INF\B313057" (Basically you copy the old driver over the new)


it sais win 10 package on 16.9.2-Sept21 and it sais WIN7 on 17.4.3-Apr 17. Is that a typpo??

 IF I AM RUNNING WINDOWS 10 64bit, DO I

Run DDU, uninstall everything.
Extract the 16.9.2 package and the 17.4.3 package.

16.9.2 being for rx 480 windows 10?? and 17.4.3 for rx 580 windows 7? or 10?

Copy the contents of the B30##### folder from the 16.9.2 package into the B31##### folder of the 17.4.3 package. Confirm overwrite files.
Run the Setup.exe in the 17.4.3 package. Install AMD display drivers. Accept unsigned drivers.

I did all that except i used windows 10 17.4.3.. didnt work. do i need to use win7  17.4.3 as in original instructions??

I am running Windows 10 x64.

I use 16.12.2 / 17.4.4.  I do get a warning about having an unsigned driver but after the driver installs I run pixel patcher 1.4.5.

There are versions of 16.x.x and 17.x.x for Windows 7/7x64 10/10x64 etc...

i am trying to run 6 rx 580 nitro+ with modded bios's hashing 30 mhs each on a z270 a pro gaming mobo from msi.. Am I missing something? 16gb ram.. 1500 watt psu silverstone.. overkill? After 4 cards I just get the black screen if the 4g decoding is on, and if it's off it just sais code error 12 "this device cannot find enough free resources blah blah" on 3 out of 2 cards. should i try what the dude was saying earlier and plug in 2 cards at a time so they can get recognized first? I'm just gathering info for tonight when I get on it again. thanks ya'll

how many watt?

finally able to use 6x RX580 but on my z77 mpower msi.
is anyone also using here XFX BE GTS RX580 8gb? i have samsung mem but not stable memshift

A lot lol, I did the math and 1Mh/s eth pays for 30W and 120Mh/s Dcr pays for 30W. The rig gets 8MH/s more Eth and ~2000MH/s more Dcr by not undervolting completely (so 740W worth of profit) and the total rig consumption from the wall is about 1450W

So the MIS Z270-A Pro on windows 10 with expansions  can runs 8 RX580 with modid bios using driver trick? You do relize that people will now go and buy  Z270-A Pro and 8x R580 . I really hope your not just paying with us.

What PSU are you using to push 8 GPUs? Thanks.

You would need a 1600 watt PSU with at least 8 PCIE connectors. Something like this would work ---- https://www.newegg.com/Product/Product.aspx?Item=N82E16817438033&cm_re=evga_1600_watt-_-17-438-033-_-Product --- or use 2 separate PSUs, ideally 1 1200 watt server psu (for 6 GPUs) and a ~600 watt atx psu (for 2 GPUs and motherboard etc). That would be the better choice imo, quite abit cheaper too.

I found the answer...


Use the 1200W version to push 6+ cards. Get a EVGA 600W supply for $40 to push the MOBO, CPU, HDD, and Riser Cards. Total is $120 for all the needed juice. Beats paying $330+ for a 1600W supply.

Thoughts?

DDU İs not working for me after restart it automatically load drivers :S how can I stop it

Sounds like windows is updating it automatically. You'll need to go to services and disable windows update.

This is a nice mining operation you got going here.

How do you manage the electricity? Is it free for you or really cheap?

I think you described my exact setup lol. Except I use the EVGA Gold 650W to maintain efficiency, ~$80. The 1200W actually only runs 900W on 110V (looking to hook up 220), so I monitored the usage on the two PSUs and I did hook one card up exclusively on the EVGA to balance the load correctly

If I knew I was going to run 8 cards again, I'd run two of the 750's instead. I could get super cheap with the mobo PSU then and use the 750's to power the risers as well

I've had  my eye on those PSU's lately.  I love the risers they sell.  From what I could tell the 750w does 750w on 110v?  I am in the process of running a 40amp circuit to my mining room with a PDU so I can use the 1200w.

I'm not too familiar with server PSU's but I know on ATX supplies you want to stay in a certain load range for max efficiency  

Thanks for the info. Please explain the order you power on your two PSUs. Do you power on the mobo first, then power on the 1200W psu? Or do you leave the 1200w psu permanently powered on during reboots/shutdowns?

1200w first, keep it on during bootups and shutdowns, turn it off if I'm doing something else. From what I read, it keeps the GPU powered in an idle state, but the heatsink is big enough to passively cool it even in low operation so I'm not worried about that

dumb question "what is with expansions?"

i like that 8 gpu setup too :)

Not dumb at all. Is it this?

http://www.ebay.com/itm/PCI-E-1X-Expansion-Kit-1-to-3-Port-Switch-Multiplier-HUB-Riser-Card-USB-Cable-/191949792720?hash=item2cb11965d0:g:M20AAOSwYmZXFl3a

Can someone provide a reputable seller of PCIe expansion kits?

Is this tip of 8 gpu also valid for rx 480?

I already use this adapter but I paid much less for it

thanks bro

Did anyone tried MSI Z170A Gaming pro carbon with 7 x RX570/580?
If so, is it stable?

I've just bought an MSI Z170A Gaming pro carbon, and just hesitate to open it... since I just saw the info from Apneal that he could pass with 8x RX570/580 on an MSI Z270A PRO. So I don't if it works also with the Z170A Gaming pro carbon. Chipsets are a little bit different...
But I don't know if it's stable for Apneal also, or has problems as told it before from others...

Thanks!!! :) Somehow I couldn't figure it out beside I passed through all the comments before.

+1 I have been wondering which  are good for the money.  You can order the same one you linked for 30-40$ from china.

Place a heatsink on top of the chip other than it hangs for a while

I have validated this one works https://www.amazon.com/gp/product/B01I2Y84TE/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1  I will be ordering bulk soon as I have gotten this to work on an old HP motherboard for a 5 gpu setup.  Just bought a lot of HP motherboards for dirt cheap

I must read this from beginning to the end when I have free time.

I just installed my 4x rx580 nitro LE and they all have Hynix Ram.  :'(

Hynix ram performs as well as Samsung ram, expect 30+ MH/s

I am working on it I tryed to copy the 1175 timing to 2000.
Like in this video https://www.youtube.com/watch?v=FT9K8DqaeDs.
But after copying the timing he is at 29mhs and I am only at 25mhs with the hynix.
I know I am a noob Its the first time I really oc a graphic card.
I watched other forum and thread but there are sooo many post.
And I dont understand all the post but I'm trying hard.
If someone can help me a little bit it will be really apreciate.
Thx for all  ;)

I have 6 installed - haven't installed the 7th one yet, but my guess is it'll work based on this driver trick.

Has anyone else tried the new AMD 17.5 driver with 6 cards yet? Or does it still only see 5 like the 17.4.4?

Yep - no problem, glad I could help.

Dear all,

FROM:

1. use DDU to clean the PC from any previous drivers.
2. Disable 4G decoding so you can log into windows (only  for Z170,H170, etc.)
3. Extract older driver for RX 400 series in Drive C: (I use 16.9.2 )
4. Extract driver for RX 500 series in Drive C: (I use 17.4.3)
5. Copy and replace all content from "C:\AMD\Non-WHQL-Win10-64Bit-Radeon-Software-Crimson-16.9.2-Sep21\Packages\Drivers\Display\WT6A_INF\B307117"  to "C:\AMD\WHQL-Win7-64Bit-Radeon-Software-Crimson-ReLive-17.4.3-Apr17\Packages\Drivers\Display\W76A_INF\B313057" (Basically you copy the old driver over the new)
6. Install the VGA cards manually from Device manager in Windows pointing path to the new driver 17.4.3 in this case.
7. Reboot and enable 4G Decoding in Bios
8. Enjoy if it works for you.




I have tried all day but I can not make this trick work... I really do not understand point 3 and 4 the rest is quite simple.., could you please advise me more precisely what I need to do for 3&4? I have 6 Msi rx Radeon 580 and the mother board is a b 250 Krait gaming also msi 6 slot.., when I tried to manually update the cards a error came out... Step 3 I need to download and install 16.9.2 and then what? Like copy the AMD file which is in the C drive to an external disc? Same for step 4? I just do not understand what you guys mean by extract to c drive the old 400 and 500..., I intstalled the version 16.9.2 on an external drive, same for the version 17.4.3, then I DDU the amd from pc and restart it. In the external disk I did copy paste the file from B307117 to B313057 and tried to update manually the drive using the path to the external disc but did not work... please help,l!!

Also in my motherboard bios , in the advance setting there is the option to enable 4g option, it says that normally only  a max of four cards are working.., and I should enable this option to run more cards..., the only problem is that If enable the option save and re-boot then the screen stays black and nothing happen..., And to be able to run windows again I must turn off power supply restart the rig and press enter to enter bios and then disable the option and restart..,, when I do this windows works again..., can someone explain why the enable option does not work? what is this black screen means?  How can I successfully enable it? is this the reason why 5 cards are not running in the first place? please help!!



Thank you

When you first run the installer, it asks where to extract to, defaults to C:\AMD\DriverVersion-Etc\

Let it extract to this location. After its done extracting, the actual AMD installer then pops up to install the drivers. Just close it. Do this for both 16.9.2 and 17.4.3. Then navigate to C:\AMD\ and copy the contents of the B307117 folder INTO the B313057 folder. It WILL ask you to overwrite files (if not, you fucked up). Accept.

The modification I'd make is to THEN run C:\AMD\WHQL-Win7-64Bit-Radeon-Software-Crimson-ReLive-17.4.3-Apr17\setup.exe (instead of installing the drivers manually). You WILL get an unsigned driver warning (if not, you fucked up) Accept. Restart.

When you first install cards. INSTALL ONE AT A TIME WITH 4G DISABLED. You'll get 4 running fine, then on the 5th, you'll get code 12's on the cards in windows. Once you tried the 5th with the 4g decode disabled, THEN enable it and boot into windows.

I got the 6 cards working fine. But i can't change the clocks or mem with claymore

Why when i use the claymore commands to change clocks does it crash. Even if i tell it to use stock clocks.

One of my identical builds i'm able to use claymore commands for clocks and voltages. What still has ahold of the clocks in windows?

Order of things
1. reinstall windows
2. driver extract. point drivers. all 6 work.
3. Run claymore with -cclock 1250 or something. And it crashes it.  Especially when i close the claymore miner window.

Please help. This is the very last thing i can't get.

After burner doesn't let me underclock more than -100

AB voltages/overclocks are more stable than Claymore settings from my experience, just use AB

I can't go below -100mv with afterburner tho.


I want to figure out how everyone is using claymore commands

Thought it could be these things.
I tried. A/v
Firewall.
DDU.
ati patcher


No fix

Hi Apneal,

What did you use to get your cards down to 8xxmV ?

I'm confused  ???
So anyone successfully configured 7xRX570 to work with MSI Z170A GAMING PRO CARBON or only 6 :).

Do you need to flash it with rx470 bios or stock rx570 or modified timings of rx570 stock?

Thanks.

You need another motherboard. B250 KRAIT GAMING supports only 4 video cards. That's what is written on the site msi: The PCI_E4 slot will be unavailable when an M.2 PCIe SSD module has been installed in the M2_2 slot.
** The PCI_E2 / PCI_E5 slot will be unavailable when an expansion card has been installed in the PCI_E3 / PCI_E6 slot.

I set the voltages in the table to 950mV in PBE and then went down from there with AB

Thank you I did the process and it installed the 4 cards only..., 5&6 no..., I even changed the motherboard from B 250 Krait gaming to Z270 tomahawk mi...,but same result! I tried to enable the 4G in the motherboard bios to use more then 4 cards but when I save and reboot it does go into black screen and nothing happen..., I tried more possibility but it just doesn't want to work...:((( anyone can help?? maybe the motherboard is the problem....

Is this confirmed working for Z170A Pro Carbon?

I'm looking forward to building myself a 7 x Rx570 Rig using the MSI Z170a Gaming Pro Carbon, Do anyone has a working solution to mine with all 7 working? :)

Just in case it helps anyone else, been having real trouble getting a 5th MSI RX580 Gaming X 8gb to work on a Asrock H81 BTC Pro R2, furthest I got was an error 43.

After trying every driver I could find, and bios settings and registry hacks etc, decided to give this a whirl and it fixed the problem straight away, now I need to pop to the shop and get a 6th card :-)

What did you do exactly to make those 5 cards work together? :)

From my experience, you have to plug in the 5th card, boot into Windows with it, let the card install and just give you the code 12, and then WHILE the 5th card is still plugged in, reboot and enable 4g decoding. Everytime I try to enable it with less than 5 cards plugged in, I get a black screen as well.

The trick that was posted earlier in the thread, here...

https://bitcointalk.org/index.php?topic=1891461.msg18858856#msg18858856

Do we know if this is working with the Z170-A Pro Carbon? Any reason it wouldnt work?

For the time being the solution and use an older driver plus pick up the rx 480
I have 5 running here.

Does anybody have a working solution to run 7 rx570s on a Msi Z170a Gaming Pro Carbon?

http://i66.tinypic.com/jaifbt.png

Read this damn thread

What version of the driver are you using?

Omg that rig is perfect and yeah I would like to see the thread where this person explained how he did that please :)

Literally explained it step by step in this very thread already lol

Excuse me but I dont seem to be able to find that exact post :/ Do you mind quoting it please? I would be really gratefull :)

I guess you'll have to be more specific about how I did what. Modding the BIOS to get 30+ MH/s is common knowledge and repeated in every thread (edit memory straps). Running >5GPUs is literally what we troubleshooted pages of information on this thread about.

Great work @Appneal, gonna try running 6+ 570s tonight on H81 pro btc.

Whats the wall power draw for those 8 gpus?

Ok fellas, first of all huge thanks to all for the dedication and effort to get this working!

My Z170A Gaming Pro Carbon now perfectly recognises 7x RX 570 GPUs.

However..
Claymore doesn't.
It sees them alright, but errors out. "openCL error -4 (0) - Cannot create DAG on gpu.

It keeps restarting.

Any ideas appreciated!

crimson relive 14.4.3

run linux, it handles these things better.

Actually, I increased virtual memory to 16400 MB and this solved that.

Amazing. 7 GPUs mining on 1 MSI Z170A Gaming Pro Carbon mobo CONFIRMED!

This community is worth gold... I mean... Bitcoin. Worth more than gold.

i like to think of it as being capable of printing legitimate apple stock for 30 cents on the dollar, back in 2000..

about some time after their second stock split.

I think i read somewhere about running 8 gpu on the gaming pro carbon mobo using a pci express hub haha, but thats insane dont you think?

More stable will use pcie x4 to m.2 adapter.

Hello guys, great news you managed to solve the 4 gpu limitation.

I have a doubt and I hope you can help me over: the point is that I am trying to follow the steps to install the cards and I want to know if I need to use the Windows 7 rx 470 drivers or if the win 10 drivers will make the trick too. Any chance that you can tell me the exact driver to download? I know this question may sound and look stupid, but if you check the procedure, the RX 470 drivers directory is from Windows 7.

This has been answered in this thread already. Yes use Win10 versions of the two.

sorry for the question, and thanks a lot for the answer :)

Hey guys can any one help me with MSI Z270 Pro A Bios settings?

I was able to install manually 6 GPU RX 570 using the technique described in earlier posts.

https://www.newegg.com/Product/Product.aspx?Item=N82E16813130993

However when I boot up it only recognizes both cards in pcix16 slots and doesn't recognize pci x1 cards

When I enable an option in BIOS for Enable 4G Encoding Yes and PEG to Gen1

Windows gives me blank screen.

Without it boots up an i can see all 6 cards but only 2 are working with Drivers. I saw a posts by a member regarding MSI Z270 6 GPU working however I cannot find the same posts again [believe me I have searched]
they had a link for newegg link thats what i used to purchase however I cannot get the damn thing working with 6 gpu.


Thank you,

Thanks to the OP for coming up with a solution, but I'm not having much luck with it :(

I'm using a ASrock H61 Pro BTC, and 4 RX570's

I cleaned all the drivers out, and made the merged driver pack as described. Updated the drivers through device manager, get the unsigned driver warning

Has anyone covered the "Windows requires a digitally signed driver" error that happens after you get through the driver install?

After the reboot all the drivers are disabled for the cards and have yellow exclamation marks in device manager.

Got me a bit stuck.

I have seen that in the past... I disabled "Program Compatibility Assistant Service" and I no longer see that error.  I already had that service disabled when setting up new rigs with 570's so I am unsure if it actually creates a problem or not.

Cool, I'll give that a try. tks

And on page 3


On top of that, make sure you do UEFI only booting, not Legacy+UEFI, and confirm that works with 4G disabled first otherwise you'll need to reinstall Windows. Also, disable Windows 7 Installer and Windows 8.1/10 WHQL and fast boot and MSI fast boot, that whole page of boot options should be disabled.

I got all 6 gpus running but when i run Claymore's dualminer there is an error:



No Amd opencl or nvidia gpus found exit

I think thats because claymore thinks that there is no amd driver installed.

Suggestions to this ?

need info: cards, os, mobo ram amount, driver versions, claymore version.

post claymores log. use the code tags when you post the log.

Has anyone tried mixing rx 470/570 in a rig?

Newest Claymore,
the driver is 17.4.3 win7 and 16.9.3 win10 to get all 6gpus running.

Do you need UEFI enabled for the newer cards (rx470/580) to work properly?

Hi,

Did any one try on Pulse RX570 4GB ? hash rate can upto how many mhz?

Does anyone have 6 rx570 gpus working on Biostar tb250 BTC motherboard?

I tried to install different drivers, activated pixel mode,also tried 6 gpu mode described here (16.9.2->17.4.3),  but only 4 cards works.
4 msi rx570 gamingX cards working perfectly alone, but after I insert 2 more Asus Strix Rx570, rig stops to work properly. Does anyone have idea how to solve this problem?

Someone tried some Rx570 ITX 4Gb ?

Hi all,
Successfully installed 5 rx570 but now when i run claymore after a couple of minutes, the computer freezes.
Im using 1200 watt and 500 watt power supply. Tried to run 4, 3, and 2 rx570 but they all freeze after a couple of minutes using claymore. So far it will only work with one rx570 installed.

Any ideas? Thanks.

I do not know if it helps more and it is possible to mix the drivers of rx 480 and rx 580

https://i.imgur.com/LZNjb2F.png

 ;D ;D ;D
I can mix the drivers
Any version for rx 580 that accepts mob without patch?
Looking for a solution then put here

I got 8, 5 are running 1100/2000/875 @ ~28.9MH eth / 640 MH dcr, the other 3 needed some mem/voltage tweaks to stop them from crashing, lowering the hashrate to about 27ETH/580DCR.

I have two 4 card rigs with almost identical hashrate, one has 4x470 and draws about 650W from the wall (bronze psu), the other has 4x570 and pulls 680W (gold psu) so they are a bit more power hungry.

Could you share your bios, please?

In every case, I have a problem: making Windows recognize my 7 cards is not a problem (driver trick) but claymore and all the other apps don't recognize driver and close immediately (it must be an opencl problem, even GPU-Z won't start if I don't force it).
Do you have a solution? Tried pixel patcher but nothing. I have a Z170A Gaming Pro Mainboard.

Thanks!

Guys, you need to have your cards on stock vbios if you want them to have a chance of installing properly. Only flash them (and apply pixel clock patcher) once you can see them all working in device manager.

I spent hours yesterday swearing at my rigs wondering why I wasn't able to install Windows... Only to realise it would never install in uefi mode as long as the video card bioses weren't stock.

If you have a program like 7zip installed you can just "extract" the folders from the .exe.

Nice :) Did you have problems making them work all together? You got 5 x 570s on the same rig maximum?

I can find 6 after hours of troubleshooting this is what ive come up with.
My computer will detect 6 GPUS if the first pci slot is not connected. Connecting to the first pci slot my computer only detects 5 GPUS. I cannot get it to detected 7 GPUS when I have all 7 slots connected. Is it a bad slot or a setting in bios I'm missing?

I'm using windows 10 64 bit

Hey there, I need some help with RX 570 Sapphire Nitro

I'm trying to flash it's BIOS. I'm changing the values of VRAM to increase hashrate by copying and pasting 1:1750MHz values over 1:2000MHz and 2:1750MHz over 2:1875 and 2:2000MHz.

After a system restart, RX 570 driver crashes and MSI Afterburner doesn't recognize the driver...

Anyone knows a solution to this issue and first of all, am I doing it right by changing those values?

what memory? only swap the settings for 2:1750 not 1:1750,1:1875 etc...  only do the 2: memory timing.
you only use 1: memory timing for certain memory maker I am not sure but i would double check by googling it. I think its Samsung only.

Elpidia and Hynix is 2: timings

Anyone else having issues with 7 but not 6 gpus in z170a?

For that matter did anyone manage to run 7 gpu's on the z170 or 270 cards?

If so, I was looking into buying the msi z170 gaming pro carbon board. Anything I need to be aware of before buying?


Thanks

hmmm i thing it's not good card for mining

what is not good card for mining?

So, I have 7 RX480 cards and am running into the same problem.

If I put 5 of them in my system, and enable 4G decoding it works great.

Once I add the 6th I can boot with 4G decoding disabled.  (Of course then only 3 cards work and 3 have Error 12 - no resources)

Trying to enable 4G decoding with 6 cards will not boot from BIOS.   It will attempt to boot twice and on the 3rd attempt will display "Preparing Automatic Repair" and then...black screen.

Any pointer how you all were able to make this work with RX480s?

System

MSI Z170a Pro Carbon
6 RX480s (8G)   (7th available)
Windows 10 Pro, 64bit
driver 17.4.4

By chance when all 7 GPUs are hooked up can you go into bios and under board explore see all 7 pcie slots connected?

I connected 6 of the up and all 6 are properly seen in BIOS.  The system would not boot with 6 however.

So you make sure you are booting into computer and you see all 6 cards? Turn off auto driver updates and windows updates. Use DDU In safe mode, restart, Manual direct each card in device manager to the driver and install. reboot with 4g enabled. and peg 0 and 1 are gen 2. You have 7 cards right? Is the 7th card seen in bios?

Yes, I boot into Windows and I see all 6 cards (with 4g disabled).  I manually direct each card to the driver.   Upon reboot I can see all 6 cards in the BIOS explorer.  From here I have 2 options. 

1.  Enable 4G decoding which causes 2 aborted booting attempts with a third stating "Preparing Automatic Repair" and ending in a black screen.
2.  Leave 4G disabled which allows me to boot into Windows with 3 cards working and 3 without sufficient resources.


Or, I can remove one riser, and boot with 4G enabled and have 5 working cards.

I do have a 7th card, but unless it is an important diagnostic step, want to get 6 cards working first.  The 7th is new in box and can still be returned if needed.

here is my way how i did it with 7 rx 470 first install windows in uefi mode using onboard grapics with a usb pen created with rufus be sure you update your bios to version 1.7...

ok if windows installed connect 4 gpus and let windows boot ddisable onboard graphics now and connect monitor to gpu in windows disable updates be sure windows doesnt install its own radeon driver windows tryes to install 17.1.1 wich will not allow modded bios so i managed to disable windows update service and manually installed 16.11.5 beta wich is the last driver wich allows modded bios so it installed the 4 gpus the next reboot enable 4g decode in bios and set pcie to gen1 then windows will boot with 7 cards and the cards gets installed by windows automatic ... after next reboot you have 7 cards... i wasnt able to get it to work with newest drivers all of my cards have modded bios so no way found now cause it gets always code 43 after ati patcher i can only get 4 crads installed but you have to disable 4 g decoding so 4 crads gets installed listet with code 43 then ati patcher makes them to work but then if i connect the other 3 and turn on 4 g decode it wont boot didnt tryed for long now but if you have rx 400 series simply use 16.11.5 drivers to get 7 modded crads to work i heared also the rx500 series allows modded bioses the driver wont check for it signature but didnt test it cause i dont have rx500 series card... sorry 4 bad english...

Wow it is very useful for newbie. The hash rate is increase and more stable than just copy the trap. I am so appreciated your help. Do you know who create this trap modifier? I want to send a little bit bitcoin or ETH to him.

I have the MSI-Z270-A-PRO, 6 RX480,
I have to do the same procedure to recognize the 6?
To manually replace and install the drivers. Will it work like this or only install the 16.9.2?
Message made in Google Translate

I have RX 580 5 card are working properly by the driver trick.
But when i plug 6 th card (disabling 4g) Device Manager recognize 3 card and shows error for other 3 card. When i restart and enable 4G then system reset and goes to repair.
What could be the problem ?

My system:
- Intel G4560
- Asus Srix 270F Gaming
- 8 gb ram
- Corsair HX1000i PSU
- Sapphire RX 580 Pulse 4GB (Modded)
- Riser Cable Ver 3.0 30cm

Windows 10 64 bit installed.

Pretty happy with that board. I got 6x sapphire rx580 8gb nitro+ hynix and just added the 7th sapphire rx580 nitro+ 4g hynix(easier to buy these days) all works charming so far. All i need is to tune the rx580 4g bios. Anyone aware if the bios from 8gb card will work for the 4gb?

So i have been trying to mine with 6 RX 570s but my system crashes with more than 4 cards. It starts mining with the 5th but crashes after ramping up the Hash rate, which is usually around a min or two of starting to mine. Windows just hangs.

Sytem:
Z270-a pro motherboard
1300 W PSU
GPUs: RX 570
RAM: 16 GB
Windows 10 64 bit

By the way, I was getting the same issue of getting a black screen on Windows boot up with the 4G turned on with the latest and every other possible driver. I got it to boot up and recognize the cards with mixing old/new drivers but that was causing other OpenCL issues with mining and not to mention none of the monitoring softwares were recognizing the drivers as legit.

What worked for me was installing the stock Crimson 17.5.1 driver after cleaning old ones with DDU. Now everything is working fine but I still cannot use more than 4 cards to mine. My system will recognize all six cards with no problem now but the system crashes when the mining initially starts ramping up the rate to around 70-80 MH/s. It seems as if there are not enough resources available or something for all of them to mine simultaneously.

Hi everyone

Hoping someone can help me (total newbie to GPU mining and unfortunately started by trying to build my own rig!)

Asrock Z270 Killer SLI
8gb ddr4 ram
Intel celeron processor
1x550w psu for the mobo
1x1800w psu for 6 gpu
6x Sapphire RX580 nitro+ 8gb
6x 1x riser cables
Windows 10 64gb

All 6 cards show up in windows device manager
3 of them are installed correctly, other 3 are not usable with  insufficient system resources available error code 12

Tried installing combined driver by cryptomined
Tried installing 17.5.1 with 16.11.5 drivers changed (followed correct procedure)

No luck

All gpu's powed with 6 and 6+2 connectors

Really stumped! Someone told me my motherboard doesnt take 6 graphic cards?

Not sure what else to do right now:(

There is usually an option in BIOS to enable 4G or Cryptomining option. Search around and I am sure it will be there. Your other 3 PCIe slots are sharing DMI with other components like USB 3.1 etc, so you need to enable the above mentioned option to dedicate the resources to those 3 slots. Hope this helps.

There is no option for cryptomining :(

I can run 4 cards with no issues but the moment we connect the 5th or 6th we get the error saying insufficient resources

please someone help

Need a little help.

Been able to mine using 4 cards while 4G is disabled. When 4G is enabled, I see all my 7 cards but when I try to mine, it says AMD display drivers have stopped working and has recovered. Unable to really mine at all.

Using Claymore 9.4. PCI settings set to Gen1, used the old and new driver merging, patched using pixel clock patcher. My cards are all 570s. My board is MSI Z170A Krait Gaming 3x. I have MSI Z170A Pro Gaming Carbons that work flawlessly with 7 GPUS.. Vendor told me that the difference between them were only the lights and that 7 gpu setup is also possible with krait gaming 3.

Anyway, I seriously need your help. Any suggestions?

There is an option. It wont be called exactly what its called for other people. Could be cryptomining. Could be 4G decoding. Could be MIMO.

Bad risers or bad overclock. Make sure each card mines without 4g first. Make sure all risers operate fine.

Hi guys !

I'm successfully running 8 x RX580 on Asus Prime Z270-A + 1 M2 to PCIE riser (232Mh/s, 980W total at the wall) thanks to the driver trick.

Just tried to go up to 9 GPUs using a second M2 riser but it's so far a no-go.
The 9 cards do show up in device manager but Windows crashes when installing driver on the 9th card.
It then blue screens after reboot : "SYSTEM THREAD EXCEPTION NOT HANDLED".

Did any of you succesfully went beyond 8 GPUs ?
Any idea what causes the crash / how to go through with the 9th driver install ?

Any feedback appreciated :)

AMD drivers are limited to 8 gpus only, that's why the 9th card is crashing.

Oh i see...
So that's a driver issue.
No known workaround found so far ?

Well, out of the blue, I would think that if your board supports PCI-Passthrough (IOMMU), You could install VMware and run the 9th card in a virtualized windows machine.

my board doesn't have 4g decoding

Only changeable option is TOLUD and we set it at 3.5gb

We are using ethOS and got 5 cards to work but the moment we connect the 6th card and it starts hashing the rig restarts...any ideas?????

Beautiful.

If you're using claymore, maybe this might help

this is our motherboard: http://www.asrock.com.tw/mb/Intel/Z270%20Killer%20SLI/index.asp#BIOS

Initially we could only get 4 cards installed and then found the above bios update. We then changed the chipset config as per attached pic (I am unsure whether i should set pcie to Gen2 or config but we followed gen2 based on a forum we read)

we then managed to install 6 cards

the cards are sapphire amd rx580 8gig gpus. I downloaded the combined drivers as per cryptomined and 1migingrig blog. I then downloaded claymore and all hashed at a total rate of 150mhz.

i overclocked as per below instructions using sapphire trixx and the modified bios in this blog:

http://1stminingrig.com/best-bios-rom-sapphire-nitro-rx-580-8gb-oc-hynix-memory-30-mhs/

Now all 6 are hashing but one is hashing at 4mhz :(

this card was earlier hashing at 0mhz and is the same card I could not get access into earlier by itself

i then moved the riser to a different pcie slot and it worked. i tried a different card on the 6th slot and it didnt work but then I changed the pcie of slot 6 to auto and it worked

still cannot get all 6 cards to hash a total of more than 150mhz

any ideas?

1. DDU clean and restart
2. 16.9.2 extract files from B folder to overwrite 17.5.1 B folder files
3. enable 4g decoding , save and turn off.
4. put 5 cards in and run
5. the computer turns on and mining rig works but the computer is extremely laggy and turns off after few seconds of mining.


Can anyone help?

Is it possible to power both 6 pin riser and card using a 6+2 splitter cable?

I have a 1000w PSU, only have 3 cards at the moment and waiting on riser but will go to a 6 cards if i can

Anyone know what 470 bios can be uploaded in a Sapphire RX570 Pulse 4gb ?

For ETH ONLY 1000PSU should do fine but with dual mining it can not.

Optimized rig of 6 GPUs should take 800-850Watts from the wall but dual minigs increases consumption.

I have 1 rx 470 and 5 RX 570. Applied some mods. Not the most optimized rig of course:

168-169 Mh/s ETH-->850-880Watts
+2700 Mh/s SIA when dual mined--> 1020-1050 Mh/s.

I rather keep my PSUs comfortable instead of squeezing every bit of juice it has.

I prefer maximum %80 capacity of PSU on full load.

What are the cards, are they RX series? It is not necessary to the driver trick anymore with 17.5.1 and 5xx series cards.
What PSU are you running, is it big enough to run 5 cards on?
Have you done any clocks or undervolts, if so, check again that you haven't gone too far.

Hello. I am new at the forum and mining, and let me thank you because i have learn a lot because of you comments.

I have almost the same problem. I can't put 5 gpu's (rx 570) to work stable. 4 works apparently fine because it will run for two days non stop at 27 m/h each. But with 5, it doesn't work stable. Could work fine for about an hour or three, or a day, before it freezes. 5 days has been the longest. It always would freeze - it says one gpu1 is o.ooo m/h and driver error. GPU1 is the one card connect to hdmi on the slot PCIEX_16. Sometimes throw this error: Watchdog GPU1 hangs in openCL call, exit... then freezes. After reboot, one card loses the patch. The driver i am using is 17.4.3 with patch. But after it hangs, one loses the patch and windows won't recognize it. i have to take and put again the patch several times till it recognizes, which i find it ridiculous and it should not be.

What i have done:

Changed the memory clock... nothing

I did the trick rx 400's 16.9.2 windows 10 64 bit to rx 500's 17.4.3 windows 10 64 bit... worst... claymore hangs when it opens with advises of driver errors.

i install the one of the later drivers, 17.5.1 which doesn't need the patch... nothing, it hangs

changed the virtual memory up... nothing

the risers are new, and changed orders of gpus... nothing

I am losing my mind. i am beginning to think it is the rig configuration, as i have read that some motherboard won't run all the gpus, even is they have the slots to do it. So i want to ask you if the rig's configuration it is ok for running 5 gpus without problem:

motherboard: Gigabyte AM3+ AMD 970 SATA 6Gbps USB 3.0 ATX AM3+ Socket DDR3 1600 Motherboards (GA-970A-DS3P)
cpu: AMD FD6300WMHKBOX FX-6300 6-Core Processor Black Edition
5 x ASUS ROG-STRIX-RX570-O4G-GAMING OC Edition GDDR5 DP HDMI DVI VR Ready AMD Graphics Card, elpida memory
4GB ram
PS 850 watts
windows 10 64 bit

If this rig's configuration is ok... what it could be happening???? please help!!!! and sorry for the long post
 

The model is RX 570 Sapphire Pulse. I have 1000W EVGA G3 Gold rated PSU which can handle prob 6 at most.

I have not done any clocks and undervolting. So are you suggesting that I just update the drivers to 17.5.1 instead of doing the tricks?

I want to lay down everything that I have experienced and learned a day before to set up my 6x RX 580 Sapphire Pulse 8GB in Windows 10 Pro with Asus Z270A Prime MOB.

1) Install Windows 10 Pro w/ only integrated GPU & no Dedicated VGAs connected.
2) Check for updates of OS.
3) Install drivers that are required for you MOB to work efficiently, by going to your MOB support page. [UPDATE to latest BIOS]
4) Now, go to 1stminingrig.com and search for their windows tweaks. Apply all of them.
5) Download latest 17.5.2 Relive drivers and extract them in C: Folder, don't install yet. Just Extract them.
6) Shut down your system and connect all of 6x VGAs.
7) Go to BIOS and make sure you make the following changes:
- x16 Link Speed: Gen2
- PCIe Link Speed: Gen2
- Disable HD Audio Driver (We don't need audio and in some cases, audio driver shares a lane and it may cause problem with one VGA)
- 4G Decoding: Disabled
- Memory Remap: Enabled
8) Start your system, go to device manager and it should show six VGAs with Microsoft Basic Driver.
9) Just go to the primary driver that is connected to the primary x16 lane and manually install the driver by locating it to driver folder in step 5.
10) It'll install Driver for all 6x Cards.
11) Go to BIOS and Enable 4G Decoding now so that there are enough available resources for all the cards to work together.
12) Done! It should boot up with 6 cards detecting and up and running.
 

I'm also planning to build a 6 GPU rig with 580's but I've always used Window 8.1 in the past since it will recognize multiple GPUs better than 7. But I got one 580 to add to my current rig running Windows 8.1 and there's no driver for it on Windows 8! I could switch to Windows 10 but I don't understand how you are using it for mining, since it will force a restart to install updates. How are you dealing with that issue?

There are RX 580 drivers for Windows 8.1 x64 The latest driver from AMD is fine.

https://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-Crimson-ReLive-Edition-17.6.1-Release-Notes.aspx

When mining in Windows 10 you have disable a lot of the backgorund services.

https://www.youtube.com/watch?v=baCCjFU-4Bk

Thank you for that! I will try those drivers when I get a chance. But officially they don't seem to be supported: https://community.amd.com/message/2803441#comment-2803441 (https://community.amd.com/message/2803441#comment-2803441)

UPDATE: OK I downloaded and tried those drivers, but they still didn't recognize my RX580 card - I see the Microsoft Basic Display driver instead. Same problem as described in this thread: https://community.amd.com/thread/215340 (https://community.amd.com/thread/215340) Does anyone here have a 570/580 working under Windows 8.1?

Give Windows 10 a try and as I posted earlier about tweaks from 1stminingrig.com. It includes disabling a lot of windows 10 background services, but as with my experience right now. Windows 10 is rock stable and my rig is currently doing 180 MH/s ETH and 3400 MH/s SIA dual for two straight days.

As far as I know there is a way to disable the updates in windows 10, I have used regedit (registry) which can be start from Start + R and then just type regedit the rest can be explained in an article below.

You only will get notification that there are some updates ready to be downloaded (It doesn't even download) nor it will update automatically.

Source 1 (https://www.howtogeek.com/224471/how-to-prevent-windows-10-from-automatically-downloading-updates/), Source 2 (https://4sysops.com/archives/disable-windows-10-update-in-the-registry-and-with-powershell/)

Hi all.

Some answers:

Asus Prime z270p +2 m2-usb (for risers adapters) run 8x480 cards just fine.

And some question:

I was not unable to make to work 5x580 on Asrock f2a88 pro+ always got crashes in miner even all 5 recognized. But most time gor one missing. At same time with Prime all works fine. Anyone have same experience with Asrock? (480&470 works just fine with it)
And i can't get afterburner to work properly. It makes 4 cards at 300mhz and i cand change it if i use "unoficial" with power-play mode. (480&470 works perfect).

Hi, excuse my English. Will it work on the motherboard ASUS PRIME Z270-A 7x RX580 4GB graphics cards on Windows 10? The board has 7 slots, but I'm not sure it works without any problems. Thank you

It does. In bios change every PCI option to gen2 and enable 4g decoding

Hi guys im about to setup a similar 7 GPU mining rig but with gtx 1060s. Is this driver problem true to all mining rigs with more than 4 GPUs or is this specific to the RX 570/580 line?

I ordered msi z97 gaming 5 motherboard.Can I run 7x570 4gb with it?

I wonder if you guys have it resolved. I had similar problems with Asus Prime Z270-A motherboard and 7x Asus RX 570 Expedition 4G OC cards. EthOS wouldn't boot with more than 4 cards plugged in.

I resolved this problem by changing motherboard settings as instructed in EthOS knowledge base. They have instructions for different motherboard makes. For me I think what helped was disabling "Fastboot". But I changed all other settings according to instructions as well.

Here's a link to these instructions for MSI, Asus and Asrock motherboards at least, but these settings are probably applicale for any motherboard:
http://ethosdistro.com/kb/#many-gpus

I've just setup an 6x GIGABYTE AORUS RADEON RX 570 4GB rig with a TB250-BTC Pro motherboard on Win 10 (I've still got some issues though)

Was quite a mission but the steps were as follows:

• Updated MB Bios
• Enable mining mode in bios
• Clean installed Win 10 Pro
• "installed" ATIwinFlash
• "installed" ATIkmDag patcher
• Created a modded rom for the first card

5x

• Applied modded rom to each card one by one
• ATIkmDag patcher

--

• installed all 6 cards and had endless driver issue i.e dont do this
• installed a single card
• removed drivers
• installed latest drivers

6x

• ATIkmDag patcher
• restart immediately
• install next card

So my issue is the following:

At core clock 1050 and mem clock 2050 I'm getting an avg. hashrate per card around 27MH. However, whenever a new job is found the hashrate decreases considerably. Sometimes even down to 3MH. Anybody got any ideas?

I have an issue when i install 4+ gpu, a random card will hash for 4 MH/s with no apparent reason...

can we do 7 gpu on asrock B250 K4?

We are testing this mobo. Will update soon.

How to the disable crossfire then when AMD settings will not be present? AB, Claymore, Trixx etc. does not have this option. Only AMD settings app has it.

Hi man,

Great job that you've done there. Can you tell me how did you manage to squeeze 30 MH/s on the 570 card with that temperature? I can only mine ETH because while using  the dual mining mode the card gets extremally hot. I can only get 20MH/s on dual mining and 25 MH/s on single mode.

Thanks in advance for your answer.

Hi KGV,

Can you share with me your settings to get this working? I am only able to get 1 M.2 port working with a pcie adapter. Everything you know would be great if you could share, please.

Thank you

Does anyone know if AMD fixed the driver issue with >5 GPU's? Can you do 6 GPU without driver tweaking or do you still need to copy that file from an older driver?

Hi Jamievs,

I am finding my 3 rigs stable with 17.5.2 relive. No need to copy over with old versions. I actually tried with the latest (16.2) and it seemed to work fine. I think after 15.2 they've made it possible to run the latest drivers for multiple cards.

Download the 17.5.2 relive drivers from here: http://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-Crimson-ReLive-Edition-17.5.2-Release-Notes.aspx , extract, and use device manager to install (as you probably already know). Make sure you use DDU to uninstall all the previous drivers first. And only do this with 1 card.

Hi,

Is it possible to run 6 GPU MSI RX580 Gaming 8 Go on the motherboard Asus Prime Z270-P?
Up to know i only get 3 GPU with success, as soon as i try 4 or 5 or 6 GPU, the result i see only 1 or 2 GPU, no more, it's sound like my config meet limitation hardware somewhere.
I see on this motherboard it is Chipset Intel Z270 Kaby Lake and the controllers of PCIE are also Intel Kaby Lake, and my cpu is Skylake-S, may be there is an compatibility issue?

My config:
Asus Prime Z270P (Last Bios 0808)
CPU G3900 Skylake-S
Memory DDR4 PC4 19200 G-SKILL 2 x 4 Go
6 GPU MSI RX580
6 Risers
Supply x2 750W (Synchronised)
Windows 10 64 Bits (version 1703)
Driver 17.6.2

In Bios 4G Decoding Enabled, PCIE Gen1.
I read this topic, and i try all suggestions i have seen, but, nothing to do, always get only 3 GPU, no more detected.
I believe i will give up, and i will order new motherboard Z270A or new CPU Kaby Lake, because i am too bad at this moment..., i need help for sure.

I found where are the issues, 3 riser cards dont work properly..., my bad that i do not checked all material one par one at the beginning.
Have a good day!

Anyone have some experience with ASRock B250M Pro 4?
I'm having problems getting the 4th and 5th card getting detected. Also, when i link the first m.2-pcie riser i lose one of the pcie cards. Seems like a bios config problem but i can't find the reason.

edit:
got the 4th card working with a m.2 to pcie adapter plus riser.
everything gen1, audio disabled and only 1 dumb plug on the card which doesn't have riser.
going to try the 5th on the other m.2 slot.


edit2:
for no reason everything got unstable after 12 hours with 4 cards. One of the GPUs (the one linked to the m.2 slot) is very unstable and hangs the process. I'm using a Corsair 750W PSU, 280W on the plug, 4xRX460 4Gb. VM 16384MB. Bios updated, win 10 pro.

edit3:
just notice that one of my cards is drawing power on a bigger gap than the others. GPU0,1,3 drawing 55W each. GPU2 drawing from 40W to 70W. (doesn't show on HWMonitor, only on GPUZ.

Any tips?

Dragonmike can you give us an update on your rig?.   

Or anyone reading... with this MoBo MSI Z170A Gaming Pro Carbon I can get 6xMSI RX580 with no problem getting 29,5MH/s ETH on each.     BUT 7xGPU is now unstable clock/volt settings.      How about MoBo BIOS and GPU BIOS?    I have both modded.   Driver 17.4.4 patched with older AMD driver 16.9.2  folder.  Same as most people with this MoBO and the RX5xxs in order to get them detected.   

I don´t have precise power measuring but my PSU is EVGA 1300W which is sufficient for the rig.   I have Windows 10 Pro.

I believe if 6xGPUs are detected, installed, patched and mining there should be no reason to freeze with the 7th but that is where I am.   If anyone has some clue I really appreciate it.

Thanks a lot
JoeZener

Tried different cards on each riser. Everything works well with 3 cards. When i get the 4th one of them gets the power drawing variable and after a while the system crashes.

edit:
Solved. PSU 750W working with 5 cards, win10, 3pcie slots plus 2 m.2 adapters.

My 6 card rig is crashing when creating the DAG, 5 cards working fine.

3 x AORUS RX570
3 x MSI ARMOR RX570
Win 10 64 bit
Tried various drivers with the same result.

Windows see's all GPU's but as soon as claymore starts creating dag it hangs. Any suggestions?

same problem here :'(

Increase virtual memory to 17500. As soon as I did this it was all ok.

thx bro...but after few minutes...got hangs again

Also having the same problem on one of my machines (mixed R9s). Anyone with solution?

Hey guys,

I read a lot about a problem with more than 4 cards and that you must combine drivers. But i expect you can start Windows, which doesnt recognise more than 4 cards.
I have a little different problem. With more than 4 cards my Win10 even wont start. I see only black screen. I can reach BIOS, thats all. With up to 4 cards everything is working perfectly.

I have motherboard Asus Prime h270-plus and Sapphire rx 580 8GB cards, PSU 1200w.
Do someone experinece same problem? I am desperate after 3 days of trying to solve this. Thanks for any help. If someone provides me a solution, my first payment will go on his adress.

If you are getting Black screen on the 5th card you need to enable 4G addressing options in the motherboard Bios.  Plug the 5th card enter the bios settings and find the option for enabling PCI bus to see more than 4 cards.     Read the thread above to find details of the option for that specific motherboard.   That is all you need then install the 5th card

Good Luck and Happy Mining

Good afternoon, can you help me?
I have the following material
asrock h110 pro btc +
sapphire rx 570 nitro + 4gb
Corsair Memory 4Gb

I only have one graph attached.

Sometimes it crashes ... I can not understand why ...
It's all fun, but the graphics give you nothing.

Do you mind letting me know what settings in the bios you had to use to get 5 cards running?

I have the same board. going to be running ubuntu, with the riser setup - 2 m.2 to pcie adapters, and then 5 risers (3 to the regular pcie and 2 to the m.2 adapters)

ill be using 1060's

is it just set 4g decoding to ON and then the upper memory lower (tulad? w.e that is) to 1gb?

Hello,

What's the best PSU to run 6 RX 570?

If you dual mine, I would go with an EVGA 1200 W G2/P2. That will give you ~25% overhead from the rated power.
