Lost 980Ti Performance

[Praesi]

Hi Guys.

 

I noticed less frames in some Games and checked my Card with Valley, Heaven and 3D Mark.

I monitored the Temps, boostclock ect. with GPU-Z and Afterburner. GPU-Z looks like always, Afterburner give me some strange Numbers 427513518% load for example)

 

Temps and Boost has not changed.99% load 1418mhz ist what GPU-Z say

I tried two different drivers, the one i used for weeks and the last one.

 

Everything looks fine, but ive lost 1k points in Valley and 9k points in Firestrike and 30-40 frames in Killing Floor2, Battlefield4, Natural Selection, just to name a few.

 

I did all the droubleshooting thats normal in weird situations, but everything looks fine, except the performance went down from yesterday to today without having me change anything. 

 

My normal Firestrike Score is 18696

now its  11931

 

Any Ideas wtf is going on?

I personally would have said drivers but you already tried prior drivers so??? What's the driver you tried besides the current one.

Dont know which one exactly. I used it for at least 6 weeks. I never change driver when everything works fine.

Than my Frames went down to 30-40 in PS2 and i thought wtf? GPU-Z say boost is still 1418mhz, so i have no idea whats going on atm...

If frequencies are the same as always, and it's not limiting itself some how for some reason (using less than 100%) then I have to imagine some other part is impeding the performance.

 

does anyone know if there is a way to test VRAM in terms of reliability, speed, etc.?  Some issue there would be my guess.

Hmm ok. I deleted again all Nvidias Files and deleted all NVidia Registry entries.

Firestrike Score is now 19666.

 

I realy dont know wtf that was, but it looks like everything is working as it should again.

 

If anyone has an idea what this could have caused, please share with me.

 

Thanks to all. If something weird should happen again, i will write here.

 

I will stress test some more now.

 

Good Night.
