ok, i've found how to reset to p2 state without rebooting your computer and without using inspector, just this nvidia-smi -rac
very useful, was a pain in the ass to reset each time i need to use other algo, which otherwise would result in a drivers crash with p0 state, like quark...probably due to the high overclock...
quark is the one with the most problems and then neoscrypt and lyra2v2 ... but quark is the worst.. even with no oc'ing.
There was a command in cuda mining - C 0 - C 1 -C 2 but there not in ccminer and I don't know if that would help in the oc'ing or not.
