New GTX 1080Ti slows down afer 5 minutes

So I ran
At least you now have something more to go on.

With what you have noted I'm not sure how GPU-Z seems fine.

Why don't you have the Afterburner graphs open BUT also have GPU-Z open and displaying the sensors page, to see the red coloured graphs, and then use GPU-Z to run the render test.

That way you can monitor in the same Window the Information provided by GPU-Z and at the same time see the constant, rather than the stepping peak and troughs of the Firestorm benchmark, Power % graph and the red graphs displayed by GPU-Z.

These are roughly done, but you get the idea.....

just keep the test running as you would have done the other and monitor and graph that type of issue you described.

You can extend by dragging the GPU-Z graphs to be more readable.

NOTE. ..

Not shown on the above but you can add the VDDC current and the 12v to the GPU-Z graph which could be useful in your case.


I done this last night and didn’t get anywhere with the GPUZ render test as it didn’t pull the Power% above 65% anyway. So I had both GPUZ and Afterburner running whilst I performed some stress tests. I was running Time Spy Extreme stress test and it crashed to desktop. There was a drop in the Power% in Afterburner like before, never to rise above 50% again. But also in GPUZ it came up with a power error when it crashed.

Is it possible for the VRMs to be overheating?

I don't know about the VRM's.

When you ran the Division benchmark in the YT video can you not run that again and monitor with the software noted and then post back to illustrate the problem that you demonstrated in that video..?
Also the GPU-Z, as mentioned previously, might indicate if the card is being capped the reason for it, under the PrefCap reasons.
It might be easier for me as I have two monitors and tend to run the diagnostic software on the second screen whilst the first is running the benchmark. But then again I have zero issues with my 1080Ti as mine just works.

With what you have tested and done I'm surprised that you are not looking towards a refund. Maybe you need to be speaking with OCUK.

Perhaps @Bailey could help within the customer service section....?
 
Sure drop me a message in the customer service section and if theres anything I can do I will do my best to help

Thanks @Bailey , I’ve just dropped a message in.

I’ve ran some more tests, I haven’t made a video yet as I’ve got a rotten cold and can’t be bothered

I ran The Division benchmark a few times and the same thing happened, as soon as the frame rate drops so does the Power%. But interestingly in GPUZ it comes up with “pwr” in the perfcap quite a bit and before the frame rate drops. Placing a large house fan at the GPU with the case side off helpe slow the process so probably heat related.

I’ve also now started experiencing crashes to the desktop when running 4K tests for a little while which is not good.

Same things are happening in both the 8700K and 930 systems.
 
When you are well enough you might want to make that video for the benefit of Bailey. Also you might wish to show both of those graphs illustrating the power drop and the PrefCap or other reasons that it might be slowing down.

Best of luck and Bailey is a most helpful person who will be able to support you.
 
Awesome news. Had the card swapped out by OCUK last week, changed it for an Aorus 1080ti instead and it has been running perfectly, even in SLI with the MSI card
