Yeap skunk have sweet spot for every brand i think. U have to manage to find the fine tunning. I am not sure about this but i bet 1080ti can grab better performance on -i 26, i think u assign intensity per gpu like -d 0,1,2,3,4,5,6 -i 25 -d 7,8,9,10,11 -i 26
Anyway i get a bad experience with krnlx, before ccminer update, i was thinking about going back to palginmod with -20% hashrate ( not the new one )
I try to fix my variation GPU volatility, i cant run watchdog without lot of reboot by GPU sometime go to 0% for 1 second, everything is fine but watchdog dont like this

When u try to reboot miner via quake, i dont know why but on ccminer build, script cant kill "irq" is state in zombie mode. So when u launch miner again, GPU cant assign correct value cause if this "irq" zombie, just do "sudo pkill -e irq" and u can launch it
Ahh... I was wondering how to set individual difficulty .. I'll give that a shot to see if I can squeeze some better perf. out of it. Thanks for the tip.
I've just gone back to using krnlx in the script since the performance is nearly identical as far as i can tell and it's stable without having to worry whether watchdog will kill it or not.
