I know of others that run 13 x 1070 on this MB. on Ethos though, not WIN 10

I don't believe it's a driver issue, more likely hardware.

Well, I sold some of the GTX 1060 6GB lately and the number of cards left went down to under 7.

No more issues.

I really starting to question if this board is really able to handle more than 6 cards.  You seem to be able to with your 8 AMD cards, so there must be something with Nvidia's drivers that induce those crash.

Anyhow, I am moving away from this MB and will go Asus and Gigabyte from now on.

Read this post, and want to add some info how my rig behaved. It may be relevant, or not.

 

Asrock H110 Pro

8 x Sapphire RX580 4G

5 X ASUS ROG STRIX 1070 Gaming 8G

1 x Corsair 650W PSU dedicated for MB and 3 GPU

1 x Corsair 850W PSU dedicated for MB and 5 GPU

1 x Corsair 850W PSU dedicated for MB and 5 GPU

Intel 4770K CPU

2x4 GB RAM

Some cheap Chinese risers.

 

Win 10

BIOS stock settings, except auto start, and disable all unnecessary functions.

Started out with 8 x RX580. Installed all at once.

Installed AMD Blockchain driver. ( 17.30 )

Found all cards in third attempt.

Run Claymore dual miner on Nanopool.

Run Rock steady 30 Mh/s dcri 28, for 3 month.

Installed 5 ASUS ROG STRIX.

Installed Nvidia driver

Installed and run Nicehash GPU miner 2.0

Started mining without any trouble, ( GPU + CPU ) tuned in ASUS GPU's

 

Then the trouble started :

After 4 hours windows froze.

Looked into Log file, and Error 41, Kernel Power.

Changed PSU, check all connections, nothing wrong.

Restart, same problem after 4 hours.

Disconnected PSU to ASUS GPU, restart, run rock steady only Claymore for 24 hours.

Reconnected ASUS PSU, same problem again.

Downloaded latest driver from Nvidia, did not help anything.

Updated Win to 1709, same problem still.

Had to reinstall AMD Blockchain driver again after WIN update.

Checked power consumption on PSU for MB, 450W, no issue.

Wondered if the CPU crashed because of MB not managing voltage correct.

Changed all auto voltage to manual.

VCCIO  1.050 V

PCH  1.200 V

DRAM  1.300V

Has been running flawlessly now for one month, RX 30Mh/s + DCRI 28, ASUS  435 SOL/s.

It's not quite that simple. What PSU are you using?

What is not that simple?  I am using a Corsair HX1200i.  I has enough connectors to power the MB 3 times, and connect 8 GPU running each at 120W.  Efficiency is 91-91% so I can't ask for better than this.

I found the online guide of the Asrock web site that indicated how to setup the board and I followed it.

1) Install 1st GPU in the x16 PCI slot.  Install Driver. Reboot. Done.
2) Install 2nd GPU in the top most mini x1 slot. Let Windows install the driver on it. Reboot. Done.

Did that up to the 7th card.


Also, I have powered the MB with the SATA power (so that's 3 total with the 2 MOLEX).

The system is now rock solid since then.

Yesterday, I added an 8th card and problem has started to rise again.

I have disabled the CPU on-board graphics to remain at 8 adapter in Windows, but the system still has issues with a display adapter become non-responsive and eventually freezing the whole thing after a few hours of running.  All GPU are 1060 6GB (with either Samsung or Micron memory) at +125 Core, +700 Memory and Power at 70%.  They draw 80-82W each.

I am starting to think that Windows is the issue in all this.

Well here is the follow up on this.

I was able to run 1 x 40h and 1 x 32h straight with no issue with the 8 x 1060 at stock clock and 70% power.  Then it froze like before (was mining Monero).

Then I moved to other currencies and I can't get more than 2-3 hours of stability without having to power off manually via the power button (still with no OC).

It is really beginning to be a problem as I can't leave my rig working alone as I don't know when it will freeze.  Temperature is not an issue as all cards are running under 60C.

I am drawing 800W only from the wall, so the 1200W PSU is more than enough.

I don't think this board is able to handle 8 cards with no issues.  I will remove some cards and retest again, but each day I feel like I should go buy something else that will provide more robustness.

Well, after removing 3 cards, my system is rock solid with the 5 remaining cards.

Will try to add a sixth one and see how it goes.

Well I ended up adding 2 more cards instead, and the freezing came back.  Everything is at stock clock and nothing is OC.

This is really not what I was expected from a MB that is supposed to be able to run up to 13 GPUs.

Is there something to check in the bios to be able to run more than 5 cards?

MB has the 2 extra Molex power connected on it just as required so I don't understand what is happening.

Should I open a ticket with Asrock?

Hi guys , i entered here just to le you know i had the same problem ,i could not get more then 2 cards working .
I turned off vtd in the bios and now it seems to work. I don´t know about the stability yet but hey it´s something you can try.

So turn off virtual system options in the bios and it should work.
yup
