boot up with less than 6 x GPUs and do the BIOS settings..

... after than insert the next 6 x GPUs

I have a tb250-btc pro motherboard that supports 12 cards and 12 1060s hooked up, but whenever I boot up I get scrolling PCIe Bus errors. The bios is set to mining mode - above 6g and SMOS supports 15 cards so theoretically there shouldn't be an issue. I know one guy here got the same board up and running with 12, but I can't seem to get over 6 without these issues. I've talked to the dev and he's working on it, but I want to ask if anyone has had and overcome this issue in the meantime.

Bootup with PCI-16x slot
Goto BIOS
Disable Sound
Power ON after power loss
On board graphics - Enabled, select IGFX
Mining Mode - Above 6G
Save reboot
plugin to onboard graphics

*** set all PCI speed to "Gen 2" if that helps

Thanks for the reply! Unfortunately this didn't help. We're still getting scrolling errors that say:

PCIe Bus Error: Severity=Corrected, type=Physical Layer, id=00db(Receiver ID)
device [8086:aZee] error status/mask=00000001/00002000

receiver error (first)

Any ideas?

Disable aspm via bios and if that doesn't help smos dev must add some kernel boot options to /etc/default/grub

I have spend 6 hours of test with this mobo and 6 cards, tried both images - normal RX and z170image. None of the bios settings help to boot up with more than 1 gpu. I tried every possible combination and it's not booting. Problem is the kernel seems to not work fine with this Biostar, this guy here have the same observation - https://www.youtube.com/watch?v=N_VoWV9ENa0&feature=youtu.be so it's not just two of us. Can we have a version for this MB, please ?

reading your post again and I assume you are using the NVIDIA smOS image.... looks like you are not Grin

I have the same board and all 12 x RX470s are working just fine

Since you have GTX-1060 you need this image, NOT the RX ones

https://simplemining.net/download/simpleminer-NV-v1103-kernel4.11.4-nvidia375.66-i915fw.imgc

setup your BIOS with 1 or 2 cards first and enable the Above 6G..., reboot and put in the rest of your cards, reboot ... you should be mining with all 12 cards

We finally got our rig running by adding pci=noaer to the boot options in grub. running stably with 12 cards now, no issues!

some guide how to do this ?

hello,

some guide will be very usefull!
btw i am also from Poland - like simplemining.net author which i very much greet!
it is a piece of good work! my congratulations!

unfortunetly, ia am a little green in those minning things,
try to build my own machine with 5 x rx 560 2gb, but after OS starts it shows only 2 of them working.
and not digging (i think becouse is 2 gb only - maybe there is some sollution?):

WATCHDOG: GPU error, you need to restart miner Sad

Binary file (standard input) matches

i have RX OS instaled on pendrive,
little old MB - GA EP35 DS3P with 2 gb ram (maybe it is little short)
Good PSU - Enermax 1250 and cards connected with riser's
those two connected to full PCI X seems to works, but the others not.

maybe someone can help me

sorry for my English, still learning

regards

Solution connect Putty Ssh from a local lan to miner, using miner as user and pass,
sudo su
nano /etc/default/grub
Change GRUB_CMDLINE_LINUX_DEFAULT="quiet" to GRUB_CMDLINE_LINUX_DEFAULT="quiet pci=noaer" (this turns off Advance Error Reporting)
Press CTRL + X to save
Select Yes
Hit Enter to confirm the file name
Enter "update-grub2"
Enter "update-initramfs -u"
Shut down the rig
