This works like a charm, except on my Asus strix 1080ti cards.
It seems to pull down the core clock as soon as I start the pill.
Same on zotac mini 1080ti. If i downclock memory from +600 to +200, core clock goes up significantly.
and what is the hashrate? I got 36/38 on mine!
On zotac mini i get around 48 mh/s with tdp 63, core 200 and mem 300. If i clock memory higher, the core frequency drops to about 1100 mh/s and the hashrate goes down to 42-43. I also have evga sc2 and palit gamerock prem with no such issues. They are steady on 51-53 mh/s with tdp 63, core +100, mem +600.
As for me it's useless to increase core for ETH.
