Hi I have 2 gtx1080ti 
Mining Zcoin (the best coin I found for 1080ti)(around 2050mhz each at 1025mv at 38degree)
on MPH (the best I found for this coin)
I get 6400KH/S on ccminer
But when locking at the Afterburner graph I see random drop in GPU usage.

I read the other post for the best ccminer (djm)  I tried every one I could find and it seem the best but...
Do you all have this,



I use the ccminer_cuda9 from DJM (30 247kb)

With this command line

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
ccminerdjm_cuda9 -a lyra2z -i 19 -o stratum+tcp://us-east.lyra2z-hub.miningpoolhub.com:20581 -u XXX.XXX




Is it normal, I just started so I did not had enough time to calculate if the hash rating from the ccminer match MPH but even if it match, the drop is a % loss of calculation power
