FPS/Performance drop over time fixed by reboot 1080 ti

[tiedye001]

My issue is very similar to http://www.tomshardware.com/answers/id-3657844/fps-drops-gtx-1080ti.html

After a fresh reboot, I can get just over 10000 in Time Spy, but after playing games for about 30 mins it drops by 30%-50%, and my fps is games drops by a similar amount.

The gpu is https://www.zotac.com/us/product/graphics_card/zotac-geforce-gtx-1080-ti-amp-extreme-core-edition

I have not manually overclocked the gpu, and the clock speeds do not appear to drop when the performance does, the card never goes above 70, (and I tried turning up the fans and that kept it around 50 and had no effect). The power usage does appear to drop as the performance drops.

Is there any way to fix this?

This is a pretty serious issue for me, it was a non trivial purchase getting this GPU and right now I'm getting the performance of something half the price.

I really hope I can get this figured out so I can make a decision on returning/replacing the GPU or whatever is necessary. I've already spent so much time trying to figure this out.

You need to update Windows 10 for one.

Alright, upgraded to 17134.376, haven't had a change to stress it yet, will do soon.

Alright, it look a little longer but I ran into the same issue, about 40% reduced performance after playing games for about 2 hours.

I just tried increasing the temp limit and maxing out the fans without increasing power limit and it had no effect.

Run 3D Mark Fire Strike and post the result link.

You have a problem with the GPU.

Here is the compare link with mine.

And the Compare link with my other machine with a GTX 1080 and 8700K....

Your GTX 1080Ti is under performing a lot, but then ZOTAC is a lower end brand.

 

[jankerson]

Are you using 2X separate PCIe Cables for the GPU?

Or one Daisy chained cable?

You should be using 2X cables.

Switched to two cables, and holy shit https://www.3dmark.com/3dm/29811662 I think you did it. I will run it for a while and make sure that this performance doesn't degrade like before but I doubt it will. Thanks you so very, very much

 

[tiedye001]

https://www.3dmark.com/3dm/29813996 after a little while, still getting some performance degradation but its much less significant. Would be nice if it could be fixed but its not absolutely necessary.

That's better, could just be the card itself now.
