Hello. I have an some problem with GPU boost clock. 368.69 drivers.
 
At some point after having my system powered on, it often happens while the system is some time idle, my GTX 1080 becomes permanently throttled. The graphics clock is halved from a maximum of 1950-1960mhz (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

There are many topics about this issue on geforce.com. Also even in our forum:

Somebody said this from link above :"Are you getting driver crashes at all??        I see it's being capped at 34.4% TDP, with PerformanceCap Reason of PWR.
That usually happens due to a driver crash if it doesn't recover properly, will get capped at low power/clocks."
 
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. So its not related to driver crash.
 
 
Any opinions ? Please help me, thank you. Is something with my card or problem is elsewhere because many peoples suffer this problem.

PC: 6700K No Oc

16gb DDR4 Kingston Hyperx

750W Corsair RM

Asus Z170-P

SSD Crucial Bx100 256GB
 
 
I have installed only GPUZ , CPUZ , FRAPS + 3 games. No installed overclocking utilities like Evga Precision or Afterburner. Thats all.

Of course first was that i check power management. All is ok default ( balanced ).

They are the default i dont change anything. And still after restart pc clocks was back to normal. I guess it is Adaptive.

Yes but many peoples suffers from this from geforce com forum. In my situation it happened just once.

I dont had driver crash.
 
But somebody said to me this:" The driver will not necessarily throw you a TDR ("Display driver stopped responding") error, either. The overclock can fail silently after X errors."

I am worried a little that can be card issue,even if driver not necessary throw a TDR error.

What you think?

"Improper overclocking causes these symptoms.

My card usually locks into a non-performance power state after too many hardware faults due to overclocking. Like others have said, a reboot will solve it, but double-check the stability of your overclocking.

The driver will not necessarily throw you a TDR ("Display driver stopped responding") error, either. The overclock can fail silently after X errors."

First time 2 weeks ago after long idling it throttled only gpu core. Second time after long idling yesterday even memory.

GPU CORE : 1164mhz throttle
Memory clock : 1152mhz instead of 1251mhz. throttle

So its still driver issue? Dont worry about memory throttle ?

I ask because peoples with this issue only mention about throttled gpu clock not memory.
In my case it throttled core clock and memory clock. That doesnt matter?

Ahh oook thx :)
