I found the directions about building a hash cracking rig from
http://www.netmux.com/blog/how-to-build-...acking-rig to be excellent.
Although it uses four GTX 1070 FEs in the text, I sub'ed four 1080 FEs without any problems.
However, the blog post specifies older software:
-Ubuntu 14.0.4.5 Desktop amd64
-Intel OpenCL Runtime 16.1 x64 Ubuntu Driver
-Nvidia Linux x86_64 375.20 Driver
-Hashcat v3.20
So these directions may not be applicable for everyone.
What may be of interest are several "gotcha" notes under the "INSTALLING SOFTWARE" section.
Check the "Step by Step" install procedures and compare with the latest software.

Hi,
just added a new GTX 1080 to my current rig.
I'm running Ubuntu 16.04 Server and I was able to control my 2 GPUs with this guide and nvidia-settings commands.
Here's my nvidia-smi:
Code:

It looks like my GPU 1 (new one) is not fully "working".
Hashcat can control its fan, but when I do:
Code:
nvidia-settings -a [gpu:1]/GPUFanControlState=1 -a [fan-1]/GPUTargetFanSpeed=100
my nvidia-smi:

and when I do:
Code:
nvidia-settings -a [gpu:2]/GPUFanControlState=1 -a [fan-2]/GPUTargetFanSpeed=100
I recive this message:
Code:
ERROR: Error assigning value 100 to attribute 'GPUTargetFanSpeed' (horse-power:0[fan:2]) as
specified in assignment '[fan-2]/GPUTargetFanSpeed=100' (Unknown Error).
It looks like GPU number it's not assigned correctly.. any ideas ?
Thanks in advance

shouldn't you use [fan:1] and [fan:2] instead ?

Same resault

Another thing, I'm using a USB raiser for GPU #1 and #2. The recently added is from a PCIe 8x (regular GPU slot) the other is from a PCIe 2x (smaller slots).

how did you set up the system? x11 and nvidia-xconfig . Did you set cool-bits etc ?
maybe this is relevant:
https://hashcat.net/forum/thread-6036-po...l#pid32262
(even if probably not up to date, but you could test)
My guess is that your 2nd card was not configured correctly with nvidia-xconfig and therefore it doesn't work anymore (or not at all for the second card)

I followed this guid, the only exception was that since I had the drivers already installed and working I just missed the step for the instalation, all the other steps I did again.
So:
--cool-bits=12
xdm
I had this done previously:
Code:
cat > /etc/X11/xdm/Xsetup << EOF
export PATH=/bin:/usr/bin:/sbin
export HOME=/root
export DISPLAY=:0
xset -dpms
xset s off
xhost +
EOF
and I also did this:
Code:
sed -i '/Driver/a \ \ \ \ Option "Interactive" "False"' /etc/X11/xorg.conf

New information:
Code:
XNVCTRLQueryTargetAttribute() failed.
This error typically occurs when you did not set up NVidia Coolbits.
To fix, run this command:
sudo nvidia-xconfig --cool-bits=12
Do not forget to restart X afterwards.
When running hashcat I have this error, but it seems to work normally.. in my xorg I have all devices and screens with "correct" config I think.
I used the above commands to create it

maybe it's just a problem of communication, but you must make sure that you use all the steps
nvidia-xconfig
sed
nvidia-settings
(and eventually also nvidia-smi to set the power limit)
also see:
https://hashcat.net/forum/thread-4569-po...l#pid25931
https://hashcat.net/forum/thread-5498-po...l#pid29740
(both of these links might already be very old and the settings have changed slightly, but the general idea is still the same)

Very strange, I can set some values, but not the funspeed...
Code:

NV often changes the attribute names (when driver version updates).
