Hello. I have an some problem with my system/gpu/mobo I dont know which exactly.

At some point after having my system powered on, it often happens while the system is idle few days, my GTX 1080 becomes permanently throttled. The graphics clock is halved from a maximum of 1990-2000mhz (factory OC) to 1285mhz . When this occurs, it doesn't matter how much I load my card, be it games or other demanding applications, it does not ever go past the above caps. The only solution I have had up until now was to reboot the system .GPU-Z reports the "perfcap" reason as PWR

And I have found many topics with the same issue on internet, its one of them even with Gtx 970/980/1070/1080:

Just worried because I found topic about similiar issue here: https://linustechtips.com/main/topic/38 ... ock-speed/

And reason was not stable oc. So maybe I have not stable factory OC? Also they had driver crashes from the link above, but me not, I have 0 driver crashes. And normally the event log will show the drive crash report which in my case it doesn't show.

Maybe this is different situation because my card must be idle few days and I dont have driver crash.

Any opinions ? Please help me, thank you.

PC: 6700K No Oc

16gb DDR4 Kingston Hyperx

750W Corsair RM

Asus Z170-P

SSD Crucial Bx100 256GB

Gigabyte Gtx 1080 Xtreme

This probably isn't the appropriate site or forum for diagnostics and problems but I have a few suggestions:

First, I would suspect any software utilities like MSI Afterburner, Precision X, Asus AI Suite, etc. If you have any of those, make sure they're not on auto start, restart your PC if they were, keep them closed and see what happens.

Go through the power settings in Windows and make sure there aren't any weird settings in there. Personally, I just use the default "balanced" plan.

Check "power management mode" in the global 3d settings in the Nvidia control panel. I use adaptive.

See if there are any PCIE power management options in your motherboards bios and try disabling them.

And lastly, I would try reinstalling the drivers. Follow this guide to uninstall the driver and remove all the files: http://www.overclock.net/t/1150443/how- ... s-new-2016

And this one for AMD drivers if you've previously used AMD cards: http://www.overclock.net/t/988215/how-t ... s-new-2016

Or use DisplayDriverUninstaller and then install the latest stable driver.

If none of that fixes it then I would contact Gigabyte.
