Gtx 980Ti Low Core Clock Speeds After Idle

Hi there,

I have built this computer 1 month ago and usually have kept it running 24/7. Under normal circumstances my GPU(evga 980ti classified) would hit 1380mhz, purely turbo boost and no OC and stay there until the end of the gaming session.

I have noticed after long periods of non-gpu intensive tasks, say 4-6hours or a day, and I fire a game up the 980ti would only hit ~1100mhz or lower. I've even had occurrences where the gpu would go as low as ~800 which is even lower than the reference 980ti clock speeds. Its not a thermal issue, my gpu doesn't go over 75 degrees Celsius. The CPU(i5-6600k 4.3Ghz) is not bottle-necking. This issue can be solved by restarting the computer. Not trying to be picky about restarting, I was wondering if it is a memory problem on the gpu that requires flushing or something similar.

This problem has been happening consistently and I am looking for an alternative way to solve it other than restarting every time.

Thank you and any help would be greatly appreciated!
 
Do you have v-sync on? Some games are so simple it doesn't take a high clock speed to reach the target framerate (usually 60, but whatever the refresh rate of the monitor is when v-sync is on).

The other possibility is that the video card driver had actually crashed and recovered at some point, but the system's no longer able to accurately track the clock speed. This is basically the fault of the monitoring software. Are you using MSI Afterburner? Try exiting and restarting that app instead of a full system restart to see if there's any difference.

V-sync is always off. For example I play GTAV and get 1380mhz and I start the game again in 4hours time, the gpu clocks to 1080mhz and I see a hit in frame rates as well so its not a fault on the monitoring software. I am using MSI afterburner. I just tried restarting MSI Afterburner and saw no change.
