When I set the intensity to 27 , the hashrate decreases to 131MH.
I'm on Win 7 X64 with NV driver 368.81
More testing is comming from my Pascals...
What card do you have? 2x6pins power? You should lower the memclock and try with lower intensities.
Yeah 2 * 6 pin power suppl. Their OC capabilities are better now , I could squeeze 160 Mh ( 1541 MHz core ) , will try lowering the memory..
