Can you detail how you get unity to work on the onboad Intel VGA? I have been wrestling for hours trying to make it work.

I installed via DVD with no GPUs installed (only onboard).

When I added the 3 gpus into slots 1-3 via risers, everything is detected, but the desktop will not come up. Just black screen.

I am able to access text terminal using ctrl-alt-F1 and log in, but I really like to have the desktop available.

Latest LTS desktop 16.04, upgraded fully but no dist-upgrade has been run.

When you have 2 cards in and boot.. does the ethernet led to the right show orange instead of green? But green with one card?

That is an interesting proposition. I am not familiar enough with the hardware to know why that would be the case. Well, I tested it out and, unfortunately, in both cases I had the green light on the Ethernet port. The only time it ever went orange was when it was booting, but this was the same for one or two cards connected.

I'm having the same problem .. windows 8.1.

Been working on it for days.. no solution yet. I'm so close to doing a RMA on the mobo.

EDIT: Do an RMA... looks like a bad batch from china.


I have now picked up an old mobo and the two GPUs work there right out of the box, as it were! Will definitely contact my vendors and do an RMA.

Thank you for your input.
I found that there wasn't enough power to the mobo pcie lane 2x molex extra power connectors. Those extra power connectors seem to need +12v from two different rails.
This is a second mobo. The first doing an rma.
I had to do a work around and had to leave onboard graphics on to get it to run.
I think I'm missing 1 driver.
Good luck. Smiley

Dear Crypto gurus!

I am building my first mining rig and seemed to have hit a snag! My system hardware is below:

  • Motherboard: ASRock H81 Pro BTC R2.0
  • CPU: Intel Core i3-4170
  • GPU: 2x AMD Radeon Vega 64 (MSI and Saphire)
  • SSD: 120 GB Kingston
  • Memory:  2x4GB DDR3 1600MHz
  • PCI-risers: Redukce PCIe x16 na PCIe x1
  • PSU: COOLER MASTER 1200W Modular 80+ Platinum

I installed Ubuntu 16.04 and the AMDGPU-Pro 17.50 Drivers. I have run both GPUs in single mode on the 16x PCIe before putting them on the risers, which I also tested if the risers worked by only having one GPU on the riser and connected to the monitor. Everything worked.

Code:
miner@mining:~$ uname -a
Linux mining 4.10.0-28-generic #32~16.04.2-Ubuntu SMP Thu Jul 20 10:19:48 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Installing the AMDGPU-pro drivers followed the AMD website (http://support.amd.com/en-us/kb-articles/Pages/Installation-Instructions-for-amdgpu-Graphics-Stacks.aspx).

Where it starts causing issues is when the second GPU is added on one of the other 1x PCIe slots (I started by putting the second GPU on the first, closest to the CPU, 1x PCIe).

Running
Code:
miner@mining:~$ lspci | grep VGA
03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Device 687f (rev c1)
07:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Device 687f (rev c1)

Show that both GPUs are being picked up by the system.

However,

I am at odds what to do next. I reverted back to a older Linux kernel (4.10.0) after doing a dist-upgrade.

I wonder if anyone else has had this experience recently and managed to troubleshoot it? Funnily enough, Claymore miner sees the second GPUs temperature and fan speed:
Code:
GPU0 t=85C fan=44%, GPU1 t=28C fan=13%
ETH: 01/27/18-20:17:57 - New job from eu1.ethermine.org:4444
ETH - Total Speed: 33.030 Mh/s, Total Shares: 0, Rejected: 0, Time: 00:01
ETH: GPU0 33.030 Mh/s

Thank you in advance and happy mining.
