I am use ubuntu 14.04, and I have five gpus, :
01:00.0 VGA compatible controller: NVIDIA Corporation Device 1c02 (rev a1)
01:00.1 Audio device: NVIDIA Corporation Device 10f1 (rev a1)
03:00.0 VGA compatible controller: NVIDIA Corporation Device 1c02 (rev a1)
03:00.1 Audio device: NVIDIA Corporation Device 10f1 (rev a1)
04:00.0 VGA compatible controller: NVIDIA Corporation Device 1c02 (rev a1)
04:00.1 Audio device: NVIDIA Corporation Device 10f1 (rev a1)
06:00.0 VGA compatible controller: NVIDIA Corporation Device 1c02 (rev a1)
06:00.1 Audio device: NVIDIA Corporation Device 10f1 (rev a1)
07:00.0 VGA compatible controller: NVIDIA Corporation Device 1c02 (rev a1)
07:00.1 Audio device: NVIDIA Corporation Device 10f1 (rev a1)
but when I run :
it only show 4 gpus:
GPU0: 74 Sol/s GPU1: 281 Sol/s GPU2: 283 Sol/s GPU3: 281 Sol/s
I don't know why, can anybody help me ?
what GPUs are you using? they are all 1060 ? (or are you mixing different GPUs?), what power limit?, are you OCing?, what motherboard, what kind of risers, are your risers powered?, EWBF miner on 1404 is a no brainer, it just works perfectly, it has to be something in the hardware, :p plz answer that, see if we can figure it out
cheers
Indkt.
I use 5 1060 gpus, they all are 1060.
I don't know how to set the power limit, and don't set OCing...
The MB is mis z170-a-pro
I aslo think it's the problem of hardware
I have found the problem, i run : dmesg | grep NVRM
[ 2.312373] NVRM: This PCI I/O region assigned to your NVIDIA device is invalid:
[ 2.312373] NVRM: BAR1 is 0M @ 0x0 (PCI:0000:07:00.0)
[ 2.312374] NVRM: The system BIOS may have misconfigured your GPU.
[ 2.313548] NVRM: The NVIDIA probe routine failed for 1 device(s).
[ 2.313551] NVRM: loading NVIDIA UNIX x86_64 Kernel Module 375.51 Wed Mar 22 10:26:12 PDT 2017 (using threaded interrupts)
So the 0000:07:00.0 is the unmount gpu, but i don't know how to solve it , this is my mb:
https://www.msi.com/Motherboard/Z170A-GAMING-PRO.html#hero-specificationif you have a free port PCI-E try different combinations leaving always one port free, on MSI sometimes the one at the left of the 16x one is shared with the primary 16x and sometimes will not detected it as a GPU.
if you have populated all the PCI-E then it's more complicated
try reset the bios to defaults.
disable EVERTHING you don't need (onboard audio, serial and parallel ports, if you boot from USB flash drive, disable SATA controller) disable onboard video if you have it, disable HDMI audio, disable USB 3.0 interfase (leave 2.0 only) doing it it will free enough resources so you have more extra for the remaining GPU
it could be a faulty Riser, the only way to know is trying 1 card, then 2 , then three , until you get them all, once you found which one is it, then go back to the previous combination that worked (ie if 4 worked, but not 5, go back to 4) but now, unplug one of the good ones and plug the problematic one, if you still can see 4, then it's not the riser/card it is the motherboard.
i'm not sure i explained myself correctly on the last one hehe, hope you get what i try to say hehe
cheers
