These cards, they are originally not 'intended' for compute work, so they start mining in P0 state and then, after a short period they switch back to P2 state and that messes up all overclock speeds and whatnot.
Therefor it is a good idea to disable this "Force P2 State" feature for mining.

  • first of all! Stop any miners
  • choose mem +0, core +0 overclocking in MSI Afterburner
  • in your RainbowMiner directory, goto "Includes\NvidiaProfileInspector"
  • start program "NvidiaProfileInspector.exe"
  • when you are running that, go down to section 5: there is a setting "CUDA - Force P2 State". Set this to "Off" and click "Apply Settings" button on the top right.
  • now your cards should be able to work and stay in P0 state
  • important: the reference levels for overclocking are now shifted. You will have to redo all your overclocking profiles, so that you do not run the cards out of their limits.

A last note: everytime you update the Nvidia drivers, the "Force P2 State" will be reset to "On", again. Do not forget to use NvidiaProfileInspector.exe to set it to "Off" again.

Will try that as soon as X16r profits goes down.. :) Btw, I need to tune the OC settings that you recommended in ticket 33 or can I still use the same profiles?

Which GTX1080ti do you use, exactly? I could look up the numbers.

I use the following devices.
6x MSI GeForce GTX 1080 Ti Gaming X 2xHDMI 2xDP 11GB
1x Colorful iGame GTX 1080 Ti Vulcan AD

Adding the NVSMI printout if it helps..

P.s I changed to P0 state with nvidia inspector and so far 6h mining lyra2re2 with no crash... (but OC settings from ticket 33) as you recommended. Seems Like p0 did the trick?

Super :) Yes, disabling the "Force P2 state" on these cards is IMHO mandatory for stable mining operation. I will look up the best values for your cards.

It should be there. Did you use the included version of the Nvidia Profile Inspector? Which GPUs are installed and which Nvidia driver version are you using?
I just tried:
