Gigabyte g1 gaming 1070. Samsung memory
Driver : 394.84 (important)
Os: windows 8.1
tdp: 100%
memclock -500
coreclock +150
Default intensity (no -i parameter specified in the batfile)
Hashrate 31.5 Mhash with sp-mod #6
I dont use ur SP, i am not donator and i dont try to find it another way.
I think u can push a little bit your 1070, try to lower memclock by 1000 and push a little bit your coreclock mb +10/20, u grab nothing from memclock.
I use ASUS 1070 8OG ( more hard to find sweep spot )
i can run them stable at 130/140 CoreClock - -2000MemClock ( i use linux so -1000 for win user ) and grab 30.3/30.8 on krnlx mod, i dont try the palgin new release from 2 day cause only win release

Minimum mem clock on windows is -500.
Also, problem with Asus DUAL OC 8gb is they dont have so badass cooling like 3 fan cards etc. If i put them to higher Power limit then 65 or 70% they heat a lot. I try to keep them under 60 degrees.
