Hi,
I am Mining Ethereum and Decred (or just Ethereum) with ethermine (and suprnova for Decred).
I have a GTX 1070 (only one, it is my first try on this) in my gaming computer. So I downloaded claymore and followed a few tutorials and explanations about configuring my miner.
I have a good 27.7 Hashrate with stock settings and after OC and some tweaks I have reached 30.5 Hashrate in solo mining.
I am using Windows 8.1 Pro.
My problem is that, for example with the stock settings, my 27.7 hashrate only stays if I am somehow using the computer at the same time that I am mining. If I let it mining alone, closing every other program, etc, my Hashrate drops, in 3 or 4 minutes, to 18. And this happens always, after I have been AFK.
After that, the miner remains in 17~19 for hours, being consistent and stable, but at 18 and not at my 27 peaks.
But, if I stays using the computer, the miner remains in 27~28 being consistent and stable.
Do anyone have any clue about what can be happening ?
I already tried tweaking power options and can't make it change a bit. It is still the same (may be it is still the power options and I lacked on changing the proper setting, i don't know).
Thanks a lot. I am pretty knew on mining.
I quote myself to bump my post.
Do anyone have the same issue ? I've been surfing forums all around and can't find anyone with this issue.

My guess is, that this is related to GPU's power levels. I use GTX 970 on Ubuntu 16.04 and it has four power levels 0..3. When I'm mining, it spontaneously goes to level 2, but I can force it to level 3, and it gives slightly better hashrate with it.
Check GPU's power level, if it changes as your hashrate changes.
