H110 Pro BTC+ 9th GPU on Ubuntu

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

Hello all,

I'm building a 13 GPU rig using the H110 pro btc+. It currently runs 
with 2 Nvidia GTX 1070 TI's and 6 GTX 1070's, but once I add the 9th 
(1070) it won't start. I'm running Ubunto 16.04. After trying to boot 
for 45 seconds it gives me a black screen saying /dcv/sda2: clean, 
273139/6774784 files, 2382739/27088128 blocks.

I was using the Nvidia driver version 384.98 and tried it with the 
newer 387.34, no luck with either. I have a 120gb SSD hard drive, Intel 
Celeron G3900, 8GB RAM, and three 1000W gold standard PSU's chained 
together with add2psu. If anyone has an idea of what's wrong or could 
point me in the right direction that'd be much appreciated.
I've tried using a different GPU (it was another nvidia 1070, I don't have access to any AMDs). I've also flashed to the latest BIOS.

Thanks.
ETA: BIOS options for chipset configuration are as follows:
Power warning: enabled
Primary Graphics Adapter: PCIE2
Above 4GB MMIO BIOS assignment: enabled
VT-d: enabled
PCIE Link Speed (PCIE 1-7): Auto
All ASPM Support (PCIE, PCH, DMI, PCH DMI): Disabled
I0APIC 24-119 Entries: Enabled
Share Memory: Auto
IGPU Multi-Monitor: Disabled
Onboard LAN: Enabled
Onboard HD Audi: Auto
Front Panel: HD
Restore on AC/Power Loss: Power On

	Stumbled upon this post and Parsec's response: http://forum.asrock.com/forum_posts.asp?TID=6589&KW=h110+pro&PID=40383&title=h110-pro-btc-cannot-boot-with-more-than-9-gpu#40383 I disabled VT-d, now when trying to boot I get a pop-up saying "The system is running in low-graphics mode. Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself." I'm not sure if this is a step forward or backwards, but it's something at least. Continuing past the pop-up gave me some options to trouble shoot and access some configs. I tried continuing to run in low graphics mode, it gave me the same screen as before but it also had the Ubuntu loading symbol on the screen, and it seemed to get stuck here.

	Followed the rest of that guide, no luck. I posted on the reddit.com/r/gpumining subreddit as well (https://www.reddit.com/r/gpumining/comments/7kqjf1/rig_wont_start_after_adding_9th_gpu_out_of_13_gpu/), and a user there said he had the same issue but on Windows, and increasing the virtual memory solved it. After some googling I learned that swap files are more or less Linux's version of virtual memory, so I followed this guide https://www.techwalla.com/articles/how-to-increase-virtual-memory-in-linux but added 50GB to the swap (I wasn't going to use those on a mining rig anyway ). Still no luck. Oh, I also created an imgur album (https://imgur.com/a/rCIRl) of the error I get when trying to start it up. The first few pictures are probably pretty worthless, but maybe someone with better computer skills and google-fu can make some sense of the xserver.log? I dunno, this is the first time I've ever had to ask for help on a forum, so I'm at my wit's end. Edited by dane1414 - 20 Dec 2017 at 6:43am
