GTX 1080 FE overclock
#1
Im very new to all this and have my system running with a GTX 1080 Founders Edition from Nvidia

I did a quick test on a wpa2 hash with rockyou.txt  and this was the output:

Code:

HWMon.Dev.#2.....: Temp: 57c Fan: 37% Util:100% Core:1847MHz Mem:4513MHz Bus:16


This is a very significant improvement than a cpu attempt which took about 2 hours..  But im wondering if i should do anything to optimize the GPU, how do i overclock, and/or does hashcat automatically optimize the GPU

You should be able to get at least 400 KH/s out of a GTX 1080 on stock clocks. Look at raising the power limit and changing the PowerMizer mode before you start overclocking.

you mean in the NVIDIA X Server Settings? I tried that and it still cracks at the same speed to the second.. i'll try again and check the kH/s

Ok, weird.. it defaulted back, but just changed it again to Maximum Performance and got 341.9 kH/s (48.77ms) so even less on the kH/s hmm.. what could be the problem? I am NOT using a riser.. plugged directly into the pci slot.

my watt consumption jumps from around 70 to about 220 when running hashcat

Start here:

https://hashcat.net/forum/thread-5051-po...l#pid28022

Then raise the power limit with `nvidia-smi -pl <limit>`

I tried that, but its already at its max of 217..  I am thinking i need to up the temp threshold, because if i monitor close, i get up to 400 but as soon as the temp gets up to 75c it seems to start throttling down back to around 350

could part of the problem be the display that is also running on that card at 3440x1440?

Ok so right now i have the power limit set to the max 217, and im running it with a evga hybrid all in one water cooler block.. its running at 39 degrees celcius and still I am only getting around 370kH/s

any ideas?

Overclock with nvidia-settings commands:

Code:
nvidia-settings -a GPUPowerMizerMode=1 --ctrl-display=:0
nvidia-settings -a GPUGraphicsClockOffset[3]=200 --ctrl-display=:0
nvidia-settings -a GPUFanControlState=1 --ctrl-display=:0

The above example sets the clock to +200 Mhz faster than the factory clock.  Also, the fan control state can be controlled by hashcat with --gpu-temp-retain.  Manual control of the fan isn't strictly necessary, which makes that bottom line optional.

In order to reset, you might need to do this:

Code:
nvidia-settings -a GPUGraphicsClockOffset[3]=0 --ctrl-display=:0
nvidia-settings -a GPUPowerMizerMode=0 --ctrl-display=:0
nvidia-settings -a GPUFanControlState=0 --ctrl-display=:0

You might need to do this first, before the above.

Code:
cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak

nvidia-xconfig -s -a --force-generate --allow-empty-initial-configuration \
   --cool-bits=12 --registry-dwords="PerfLevelSrc=0x2222" \
   --no-sli --connected-monitor="DFP-0" -o /etc/X11/xorg.conf

sed -i '/Driver/a     Option         "Interactive" "False"' /etc/X11/xorg.conf

Cool bits needs the proper settings.  You might need to reboot after you set this.
