I own Asus RX 480 ROG 8 gb.My mobo is Asrock H81 and , cpu is 3250 Intel.

I also have R390 nad RX480 reference without problems.However with my new card only 4 of them works but 1 remains .Same for the 10 rigs.Any suggestions?

This situation is valid for 10 rigs.

I offer 0.05 BTC price for the first, valid solution.

Additional info: I use server PSUs for powers.They work without problem for my other rigs.

My ram are ddr3 and 8 gb.

Hard disk is ssd, 120 gb.

High quality risers.

OS is Windows 10, licenced.

No virus protection program enabled.

Virtual memory is set to 16 Gb.

Batchfile is the same for my other rigs which work perfectly.

Are all of your cards connected to the same server PSU or you are using 2 different psus , one for MB and cpu and other one for GPU power ?  When you said Same for the 10 rigs did you mean that you have 10 completely same rigs and you tried adding this card to every single one of them or what ?

I'm wondering how you say (from what i understand) that your rig has 5 GPU's?

http://www.asrock.com/mb/photo/H81M(L3).jpg

I have HP 1500 watt server PSUs.To feed mother board and one card I also have a corsair CX750 M.

I bought 50 cards.I have got 10 pcs of 5 card rigs.

Either feeding from server psu or from corsair 4 cards works perfectly.However the fifth one does not work.I can see it at the configuration with a yellow label warning.

I have Asrock Pro Btc as mobo.

I didn't understand... What mean 1 gpu remains, what miner detect? any error in device manager? maybe you need apply 6xgpu mod again?

That clears things up, it slipped that H81 was a chipset  :D
Have you tried changing the PCI-E settings in the BIOS?

1. Upgrade BIOS to last version for the motherboard.
2. Switch off in BIOS all hardware not needed for rig functioning (ex. integrated graphics, sound, communication ports...)
3. Make in BIOS PCIe to gen2 mode, if not successful than gen1.
4. Install 7GPU hack https://bitcointalk.org/index.php?topic=712228.0 (https://bitcointalk.org/index.php?topic=712228.0)
5. If above does not work, please provide exact motherboard type

Are you using 2 PSUs for 1 Rig? 1 server psu for GPUs and 1 standard PSU for Mobo's?
If yes then there is timing issue.
Do change your risers and use USB Power risers with big capacitor.
For RX 480 use 16.9.2 and for 390 use 15.12.

Thats it you will be fine :)

EDIT: There is no issue in your RAM neither in SSD, Windows10 and in Antivirus.
Just do what i said above and keep your rig shutdown atleast for 1hour or so.
Then you are good to go.

problem may be about ULPS

ULPS is an ultra low power saving feature which turns off all GPU's except the primary one in use. ULPS can cause crashing / stuttering / reduced scaling when enabled. ULPS is always enabled by default. It can't be fully disabled via software such as MSI Afterburner or Sapphire Trixx (as of 11/01/2016) since AMD Crimson (and some previous CCC versions) changed various reg entries which controlled ULPS. Before following the guide, read the Q & A below.

Solution

1) Click Start - Type regedit.exe and hit enter.
2) In reg editor, press F3 and type EnableULPS, hit enter.

3) Keep pressing F3 until it finds a key called EnableUlps in a sub folder called 0000
4) Double click the reg entry and change value from 1 to 0.

5) Keep pressing F3 until it finds a key called EnableUlps in a sub folder called 0001
6) Double click the reg entry and change value from 1 to 0.

Thanks for the answers.

I will try and give feed back ASAP.

A friend sent a PM to check crossfire setup and close it.It did not work.

I have different versions of powered risers.Risers are not the reason.

I will try your offerings ASAP.



PS:My motherboard is H81 Pro Btc by Asrock.

download newer or last AMD driver, unpack it default is C:\
open Manage, then right click to that yellow labeled GPU then Update Driver Software and Browse my computer for driver software, then point were you unpacked AMD driver and wait for installation to finish.

:) Already done.It was my very first thing to do.

It seems to be reasoned by DDU.

I will share how I have done ASA I find the solution.

The solution is simple. First remove all gfx cards, all non essential HDDs and anything else attached to mothereboard battery to reset mobo, connect monitor to onboard hdmi and proceed

1) Reinstall battery
2) Boot (if some screen pops up about molex connectors ) hit 'n'
3) once you see bios screen , Go to advanced chip settings and make sure PCI-e versions are set to 'gen 1' and the preferred display out is PCI-e and not onboard GPU. Save the settings and shut down.
4) Use one gfx card , connect VGA/hdmi cable to it
5) attach the usb riser to the card and mobo 'on the first pcie x16 slot on H81BTC pro' and gfx card.
6) boot
7) Install gfx card drivers and shut down
8) now move the usb riser to first X1-pcie slot and boot.. Shutdown once you get the screen
9) Repeat the process on each of the pci-e 4 connectors .. one at a time (This way you know if some connector is bad too)
10) If all the pci-e connectors are able to show display and boot and let the drivers install.
11) Now that we know all pci-e connectors could identify gfx card , connect pci-e risers to other cards and connect all of them to all 6 pci-e slots.
12) Move the hdmi to gfx card connected to first pci-e x16 and boot.
13) all 6 gfx card should be seen now on the device manager.
14) You DO NOT need registry hack for 6 gfx cards in windows 10.

Let me know what happens

  I have done so many things...

I have uninstalled all the drivers with DDU.


I have changed the pci-e bios settings to gen1.

I have reloaded only the driver for GPU.

I have connected GPUs one by one.

Well, it worked for half an hour.With 1 GPU missing (yellow alert).

I have checked all the molex cables, powered risers...Everything seems well.

This situation is valid for my other 9 rigs.

Well, I will try Ubuntu as software.If any suggestions pls feel free to PM.The prize is still valid.

Best Regards

When going over 4 GPU's you must connect a molex power cord to the motherboard according to H81 pro BTC manual. The connector is between the CPU and the first PCIE 1x slot.

What yellow sign?
Can you screenshot it and send?

Plug a monitor into the card that is not showing up and reboot!?

2gablay12
just use win8.1 or linux ;)

I see a winner here  ;D

Mother Board: H81 BTC pro
Risers:6 powered usb risers .. version 3
PSU : 1200 Watt Platinium Server PSU for 4 gepu cards, 1500 watt for five gpu cards
CPU :Intel Dual Core 3250
RAM :8 GB, 1800 Mhz
HDDs connected to mobo :120 Gb SSD

Wi Fi connection with internet adapter and ethernet Cable

Dear friend you can either use Ethos or Pimp.Which are quiete different from each other for functions but very similar coding.Both of them are linux based systems.So, what I advise you is just purchase one of them and boot your rig using the flash dirves.By the way Ubuntu is also a fork actually (Debien).

The trouble shhoting flow chart is prepared by Hasflux.Here is the link:
http://forum.ethereum.org/discussion/7457/anyone-using-asrock-h81-pro-btc/p2


[INITIAL LINUX TROUBLESHOOTING STEPS]
First let's see if the kernel even sees the hardware. Use the following two commands. Note I add comments with # symbol but they are not intended to be typed in the terminal.

1. Ssh into the machine or if your running it non headless open a new terminal.(all of my rigs run headless and have no x windows running but with linux amd cards you do have to run a basic x server if you desire to kill your cards life span by playing around with over clocking and undervolting. Truthfully your better off using a custom bios on your card for this anyway and not run a memory hard x server.)
2. # We need to update the pciids to the latest list so the commands we use will recognize all of the cards properly. Run the following command...

sudo update-pciids

3. # Now let's see what VGA devices the system is detecting as connected without relying on the drivers

lspci | grep VGA

# there you will see a nice list of all VGA devices. If you see all six then that elemenates the motherboard and linux as the problem. If thar command only shows 5 then try disconnecting all cards and move the card one by one through your pci slots to find the offending pci slot. If it detects each slot fine try it with the next card and continue until you find either the bad pci slot or the bad gpu and proceed to do an RMA with your vendor.

[Driver Trouble Shooting Steps]

Assuming everything passed our pre trouble shooting steps we have elemenated most possible hardware problems but one more may show up as we troubleshoot our 6 GPU issue. Now we need to check the drivers.

1. Run the following command.

clinfo

# Does the command show all your devices from the opencl drivers perspective or is the driver failing to see them all. NOTE: if the clinfo hangs for a long time and does not return anything then one of your cards is bad and you will have to try the command one by one disconnecting individual GPU and proceed to do an RMA once you find the offending hardware.

2. Assuming you do have the AMD Proprietary drivers installed and clinfo worked ok the next step is to make sure the devices were initialized properly by the driver. Use the following command.

sudo aticonfig --initial --adapter=all -f
sudo shutdown -r now

Once the system comes back up open a terminal and a final check on the configuration with the following command

sudo aticonfig --list-adapters

All your adapters should be showing up now and that pesky sixth gpu is ready to mine with or its in the mail at this point for an RMA

I am also very much interested in your poblem since it is a little bit awkward.To be more open I am not quiete sure either it is a software problem or a hard ware problem.

Let's think the possible problems and eliminate.


Bios:Updated, pci-e version 1; OK

Molex: If one 4 pin molex is connected to motherboard, it is OK. You do not need two molex for powered risers.

PSU:Your server PSU's are ok.Corsair is enough if it is not the best option.

CPU: Oldies and cheap goodies.

Mother Board:Asrock H81 Pro BTC, well known and cheap still a good option.

RAM:8 Gb. You must be rich:)

SSD:120 Gb SSD.Check the virtual memory.16 Gb is needed.


OS:Windows 10.   ?????? I am a linux fan.

GPU:480 Asus ROG 8Gb. What is the difference with other 480 cards.I will focus on that.


My suggestion: You have reported that the rigs work for some time, say 30 minutes and after they go.On the other hand one of the GPU is always undefined. My solution is downclock your rig and work it there.The problem is at your PSU.How?

Your GPU's have 8 pin connections, probably you convert 6 pin to 8 pin with a cable converter.If the cable is manufactured in China the quality is a matter.Just cut the cable connecter and see if it is copper or aluminium.Also read the AWG, the thickness, it must be eighteen or smaller.

Do not overclock , do not hack your GPUS.

If my answer is not satisfactory just PM me.If you provide TW I can detect the error at your system.

You got an interesting point.But he says the rig works for a time and closes.If  ULPS was the reason it should not be closed down but continue to work on 1 card.Right?

That is also a good point.What are the differences between 16.9.2 and 15.12.x ? Do they have a manual?

15.12 has no series 400 support  , other wise not really much different then 16.9.2 that supports all there cards but some older out dated stuff they no longer support and no one really uses for much  .


http://support.amd.com/en-us/download

the latest driver from amd is

Crimson Edition 16.11.5 Hotfix.
i use it with out issue

my suggestion is try after burner only to see whats on and off and turn off sync setting between cards once it loaded then hit reset for each card it may take time but it might give you a better idea of whats going on ..

and don't use extend over clocking limits, if your mixing cards.

And my last question....Why is it recommended to wait an hour?What is the logic behind that?

Which windows version?

My OS is Windows 10.The photo of the error:

https://postimg.org/image/7sd78g4sz/

if it is code 43 in properties then it is for sure you need 6x gpu mod - i wrote before, did you not try? (it is a driver problem that it can run only 4 cards) https://lbr.id.lv/6xgpu_mod/6xGPU.html

https://lbr.id.lv/6xgpu_mod/

If your problem card connected in PCI-E x16 slot, try to use x16 to x16 riser
I saw this problem on two different MB (Asrock - first x16, Asus - last x16)

edit:
you can check even without a riser - just put a GPU in PCI-E x16 directly
if problem will be solved, so - just use x16 to x16 riser to connect

As i see, you forgot to disable CPU graphics!
Disable it in a BIOS
Also, if CPU graphics set to "Auto", so use x16-x16 riser in a first slot (meet same at my Asrock Anniversary)
I'm use the cheapest non-powered one case MB supports one card freely

P.S. Asrock noted that in multi GPU system user need to install first card in x16 slot and only than install other cards (may be not need, but i'm follow a note)

YEP YEP YEP.. disable onboard graphics from ASROCK bios settings. And I think you should be good to go. Thats why I was asking for the screenshot of device manager ! Try it

As suggested before , put a monitor on this card and put the riser on the x16 slot and install the driver , than put all your cards! Connect a monitor to it it will work!

In order to get 4-6 cards to work, sometimes you need to go into the mobo settings (usually f2 or del when starting up ) and change all the pcie bandwidths to gen 2.

I have 5 rigs of RX 480.


Your graphics image kinda looks like Windows 8 or maybe Windows 10.
I've only seen this error in Windows 7, Windows 8, 8.1.



Disable On board VGA graphics in bios.
Primary Display in bios should be set to pcie graphics.

Video connector should be connected to the card with the x16 (big) pcie slot.


To run 6 cards, its best to have Windows 10 versus windows 8.1 or even Windows 7.



Your graphics image kinda looks like Windows 8 or maybe Windows 10.

If you are really running Windows 10, then you may want to do a clean reinstall.  Upgrading from Windows 7 to Windows 10 or Windows 8 to Windows 10 has caused many errors on my RX 480 systems.

Click Start Menu, Click settings, Click Update & Security, Click Recovery, Click "Learn how to start fresh with a clean installation of Windows", Download the tool and run it.

Keep your data, but wipe all other settings.   Or do a complete reinstall.

Looks like your system is corrupted.  All the words are gibberish. . . .


But seriously, most likely not a MB issue.  In my experience MB issues usually prevent windows from even seeing the card.  Most likely it is a driver issue.  I have several 6 and 7 card RX rigs with various asrock MBs including the proBTC.  I have found, with the RX series at least, the best drivers are the default ones that windows installs.  To fix your problem, run DDU or AMDs uninstaller.  Restart windows and let it install drivers.  I believe DDU turns off windows auto-detect driver setting, but you can run it again and click a button to enable.

Windows doesn't always detect all of your cards correctly, but they should still be listed somewhere in the device manager.  If they are incorrectly detected, just right click on them in device manager and select update driver.  It should correctly identify and install drivers.

If you have tried installing drivers from AMD several times, sometimes things just get too screwed up to fix (or at least will take too long to figure out).  Since it only takes me 10 mins to install win10 on an SSD, you may just want to reinstall.  Again, just let windows find its own drivers.  It does take a few mins to detect them all.  If all are not detected after 10 mins at idle, find them in device manager and click on the update drivers.

Unfortunately, I cannot get Claymore's to get temps and fan speeds, but they still all mine.

Happy mining.

Hello everyone

I have exactly the same problem!

-motherboard: asrock btc pro rev2
-cpu: Celeron G1840 2.8 GHz
-5rx 480 8go reference
-ssd
-4GB
-food lepa 1000w


It works perfectly with 4 cards, but when I add the 5th.

In the device manager there is the yellow triangle as the screenshot of gablay12.

I try full of thing

Uninstall driver with ddu,

Restart with a gpu on the pci-16

Instal driver 16.9.2, try also with the 19.9.1

it works .

I insertind the pc, I add a card.

I reboot, it also works,

And when I plug the 5th card. It is not detected by watman,

And the device manager tells me who has a problem. On the 5 th card.

So I try to put the driver in manual, but it tells me that the driver is already installed. Wtf!

Bios a day, I try gen 1 and 2.

always the same .

We can say that the motherboard can not manage 6 cards, but 4 maximum.



I do not understand ..... I know more what to do.

We will say that the problem is known.

The solution to your problem has been posted by Hotmetal.

https://lbr.id.lv/6xgpu_mod/


^^^you need this in order to see more than 4 cards in Windows 7 and 10. (I have not tried 8 so i cannot speak to it.)

I have this exact same board and had to run this mod to make it work in windows. If you are mining ETH  I would personally recommend ethOS. It is a very simple linux setup that will pretty much just work out of the box.

Thank you friend, I'll go see this.

For ethos I think about it but I know nothing about linux,













And friends I think I have found,

Apparently if you plug a card on the pci-16  blocks a pci-1.

(Yellow triangle)

So ca done 5maxi on the asrock btc h81. :(

But a pci-1 riser can be connected to the pci-16 socket on the motherboard. :)

G oto device manager and go to properties. What error code do you see? Is it 43? Dont just say yellow triangle..

I have several working.  See my post . . .or don't.  More hashes for me :)

My OS is Windows 10.

I can not use Pimp since it does not suppor RX 480 AMD cards.

Linux is a good alternative and seems the best option.I am not familiar with Linux.If nochoice I will do it.

Well, to uninstall and install option has been delivered many times.

Unlike the answers the latest catalyst version is not the best.We can discuss it later.

I am running a farm and cloning my ssd s and I have found a malware.

The rigs still work and close down about half an hour later.Very interesting other RX 480 and R9 390X cards work flowless.There is something special to the Asus ROG 8 Gb cards.

I will try Linux by tomorrow if I can not solve the problem.


PS:What is the best remote control pogram for Linux?

Finally I have solved.About two weeks ago windows released an update which causes driver failure.Well, you install the latest driver.The latest driver installation triggers a reset to your over/under clock settings.Well,I can prove it.If you use Claymore (if not switch to) you will have log files you can see it there.Further more, if you check you will see '"ATIKMPAG.SYS" which corresponds the PSU problem.

What I recommend you either switch to Linux or change your PSU.Plus malware may do the same driver update and reason failure.Good luck.If it does not snow and you have free time I can visit you at the power plant.

BR

Hello .
A great big thank you to you the friend !!!!
it works !
Finally I have my 5 cards working!
thank you !

Thanks to BTC_Istanbul problem solved.

You do not need any modification for 5 card @ windows 10.

I will not lock so people experiencing similar problems can use the info and network.

What was the problem?

maybe you need if you have other rigs to have all same rigs to work with new card because maybe is that connected i really dont know what i am talking but maybe i say true idk really i am minning beginner.

Pimp is also a great software for mining.I suggest you both use Ethos and Pimp and compare.

Hello everyone

Now I have same problem but for 6GPUs!

-Mobo: Asrock H81 Pro btc Bios v P2.30 tried with Gen1 and 2
-CPU: Intel Dual Core G3420 3.2 GHz
-6Rx 480 8gb nitro+
-RAM 8GB DDR3 1600Mhz
-SSD
-1600watt PSU

It works perfectly with 5 cards, but when I add the 6th to any slot mobo not even gives display (POST)
Again if i removed any of 6 cards and display comes and runs with 5 Cards perfectly

Any idea please why its not even give any sort of display or POST when i add 6th card on any slot ??????

Hello

I also had problems when I add my 6th card,

You have to change the registry base so that the 6 cards appear.

Here is the link: https://lbr.id.lv/6xgpu_mod/

And connect your screen to card 2 (pci 16) of the motherboard, because if you plug in card 1, I have a black screen.
