Hilariously that actually worked, downloaded and installed an app called ''mouse joggler'' and my hash rate stays constant the whole time. That probably points to a small bit of malware, I am going to try find it and remove it first before clean reinstall which would be a pain in the rear.

Will do, that Def could be the source as it is only when it detects idle. I tried a little sneak around by installing a mouse jiggler last night I will let you know if that works.

I was wondering if you could set a minimum power level for your gpu or a way to make it stay constant? eg. GPU to stay locked at 70%tdp.
I was also wondering if you can set a max/min for the amount of memory to be used by your card while mining?

Thanks

I'll give it a go but 9.5 was doing it as well thats why I updated to the new one.

Hi and thanks for even reading this as I am tearing my hair out with this.

I have been mining ETH and/or SIA on claymore with windows 10 for a few months and no problem. Then around july 28th-31st my hash rate starts to fluctuate from 30.5 M/H on eth (MEM OC'D+Power underclocked) down to 20 M/H and even 15 sometimes. The strange thing about this is that starts off perfect for the first 5 minutes at 30.5 or 300 for sia. Then when I leave the computer and come back it has already dipped down and doesn't come back up, what is even stranger is if I wiggle the mouse it will go back to 30.5 M/H for a minute or two. This has made my mining pretty unsatisfactory as the amount I mine is way down.

The solutions I tried already:

Power options- High performance windows, no hybrid sleeps or anything like that I can see.
Nvidia settings- Max performance
Overclock- I was worried I over cooked my card but I did a benchmark and its fine and tried it at default settings.
Windows update- I remember a windows update happened around the time so I reverted that but no change.
Windows defender- I disabled for one night
Bat file- This is something that could be the cause, I never changed anything but maybe I could add something to the bat file that will stop it fluctuating.
O'C software- I use MSI but I tried another and no change. (I also noted that the power curve on MSI is steady when mining at 30 M/Hs but when it drops to 15/20 the power curve has loads of tiny oscillations in it.

If anyone has any solutions, even simple ones you think I may have forgotten I would love some outside imput as I think I am going in circles.

Thanks
