Asus Strix 980ti problem

So I got a 980ti strix (on air), tested on my other pc, a 5820k, 16gb ram and 1300w psu and the score on heaven was around 1700, also tested on cinebench.
The card was running "fine" I didn't actually check if the performance was up to level, but card was fine and working.

So I went ahead installed a waterblock and put it in my regular pc a 5960x, 32gb ram and a 1200w psu and the score on heaven was around 1800, then I went to compare my score to others here on the forums and found out that my card was performing like a 780ti or low 980s (non ti).

Everything is set to max performance, nvidia drivers and windows power management.

First I didn't format my pc, I removed my old AMD GPU, removed the drivers, installed the Nvidia driver, ran heaven and my score was around 1800, only then I went to check scores on OcUK forums to find out that this score was a 780ti or low ranked 980 (non ti).

So I thought it could be windows related so went ahead and formatted my pc twice, tested 3 different drivers and installed gpu-z, msi afterburner and even the asus gpu tweaker soft as well (not at same time as afterburner), only to find out that the clock was going doing when you use the card, so that was the reason for the low score on air as well.

Long short history: My card would start clocking down to 900s or even 800s, with a temperature lower than 40C and then I noticed that my card is running at 1.01/1.02v instead of 1.2V (on gpu-z) so I installed msi afterburner and it gave me the same voltage 1.01v, tried to raise the voltage and power limit but no changes.

I made a video and you can see the card behaviour here:

Please watch it past 30s

any ideas what is the problem?

Last time we had this type of thread it turned out the user had 2 PSUs with the GPU hooked up to the second one which wasn't even turned on, guessing that's not the case here? :D

Guess the point kind of stands though - some kind of power delivery issue not allowing the card to go to full clocks. Seems unlikely it's a PSU problem since you've tried 2 assuming you connect the PEG connectors to it correctly.
 
Have you tried to reinstall Windows?

Twice

yeah, I agree that it looks like a power problem.
I think the card if faulty as I tested on my other pc and gives the same problem.
 
Are the VRMs getting too hot and throttling back the voltage? The perfCap reason is PWR meaning you must be limited somewhere with the power delivery or power target
