7000h/s (not 7000kh/s) on GTX 860m

Cracking performance lower than expected?  

* Append -O to the commandline.
 This lowers the maximum supported password- and salt-length (typically down to 32).

* Append -w 3 to the commandline.
 This can cause your screen to lag.

Since you are on mobile be careful  that you don't fry the GPU/CPU when running with -w 3 as laptops have subpar cooling.

The answer was in your post...

Thanks! That increased it to 20 000h/s but I not 20 000kh/s. Is that good for 860m when it comes to sha512crypt? The list has is like 70 hashes all with different salts.
