980 ti only running 405 Mhz?

[mni]

Hi

First post on the forum. Here it goes, I just bought a new computer last month, of course I spec'ed with a 980ti because I wanted nice, fast renders to use for my Work, as an architect. We have the program installed on a couple of pc's at work to trial the program/workflow. Those ps's are only running a Quadro k2000 so I expected a BIG jump in performance.. I got a bit of a jump, but not as radical as I thought.
That made me think what could be wrong and I started with checking how my card was running while rendering (using Gpu-z and Hwmonitor), sure enough, the card was only running at 405mhz.
Then I tried running a benchmark (Furmark) while I had octane open, but not rendering, to see if octane was just not pushing the Gpu hard enough to get it to throttle up, but the clock speed remained at 405Mhz.
Lastly I tried to shut down Octane and run the benchmark Again, this time it immediately throttled up to 12-1300mhz

What is wrong? I tried to remove and reinstall the display drivers etc.. Nothing worked!!
Hope you guys can help!

Best regard, Tobias

BTW, its octane 2.25 standalone

Possibly overheating of GPUs, what are temps when rendering?

[mni]

Nope, GPU running at 37-40 degrees Celsius, which is way below overheating.
As I said, it throttles up while gaming etc. no problem..

I have had this happen to my 980 TI everytime I overclocked it too much, did not happen with my other one though.
Are you overclocking it in any way, if so try to reduce it until it is stable?

[mni]

Actually, the card is underclocked at the moment and rock solid, even when gaming for hours it remains at 50 degrees..

[mni]

Well, Otoy support couldn't help so I RMA'ed the card. Hopefully the next one works..

Every time gpu fails you must restart Octane or a computer. Reasons for failing may be many, usually is heat and power stability and heave usage for both rendering and monitors (use priority).

What nvidia driver are you running?
