Since doing this, no more 999/700 errors for me. The card is cracking sha512 hashes at a bit over 21,000 c/s, at a temp of about 78-79 C per GPU.
I recommend you try the same, maybe it works for you as well.
I have force the P2 state with default frequency just for testing and this doesn't work.
nvidiainspector.exe -forcepstate:0,2
I have compil other open source cuda md5 cracker with last nvidia SDK and there is no problem so I guess there is something wrong in hashcat code.
