I had the same issue. 

First i made some policy to right stuff in the memory. That did not work. Then i installed GUDA drivers (i think version 8.0), next to my already installed 384.xx driver. And yes this did the job :-)

But still i am not getting any good hashrate out of my GTX 1060 3GB MSI GAMING X cards.  only around 2400h/s for my 7 cards hmmmm thats around 350 for a card. I see on internet it should do around 450...

I noticed you have to play around in the batfile with adding  -l 4x81 for example. this is to tell how much blocks per threads you want to use ..or something like that lol. Thats the part i still dont get... how i know how much threads this card has? With CPU i know how to do thats easy.  But if i open GPU Z then i cant see any info about the threads or blocks...

Cheers

I'm running into the same issue.  Did you ever get this solved?

trying to mine SMR but keep getting this error:

JSON-RPC call failed: {
quot;codequot;: -1,
quot;messagequot;: quot;invalid methodquot;
}

Using Nvidia 1070s and ccminer-skunk-krnlx

Any solution to this error?
