same here with GTX 1070

edit: fixed with install CUDA from here https://developer.nvidia.com/cuda-downloads
BTW: my PC freezed while i installed the CUDA, had to press reset button but after new boot ccminer is working

edit²: now using https://github.com/xmrMiner because ccminer was damn slow about 300 h/s only with xmrMiner i get:
[2017-09-25 15:12:01] GPU #0: GeForce GTX 1070, 676.43 H/s
[2017-09-25 15:12:10] GPU #0: GeForce GTX 1070, 669.97 H/s
[2017-09-25 15:12:10] accepted: 12/12 (100.00%), 669.97 H/s (yay!!!)

first i was using xmr-stak-nvidia but i broke it somehow when overclocked too much in afterburner since that i get very strange output in xmr-stak but hash rate was about 700 ( or im wrong and it was 600)

# Ho boys,

i found a solution to fix this problem

Install last cuda https://developer.nvidia.com/cuda-downloads?target_os=Windows&target_arch=x86_64

Install This driver http://www.nvidia.fr/download/driverResults.aspx/107595/fr

that it 👍

I HAVE THE SOLUTION!! It was happening to me yesterday, the error that causes it is your drivers, you need to reinstall or install another version of your driver

Hi Lads
I got soution Drivers are no a issue issue is with CCminer
Download CCminer from Nano pool also Download CCminerX64 (from somewhere) , rename CCminerx64 to CCminer , Copy and paste (to folder with ccminer from nanopool) override and job done !
Happy mining
