GPU issue - help please

[Pavlov]

Hi all, i'm getting all sort of issues with Octane and i fear my GPUs are faulty.
Here is a screenshot of Furmark: as you see there is something odd.

GPU 2 seems to run at 3% and it says "power limit reached". At same time it seems to use 98% of the cores.
GPU_1 seems to use 0% of the cores but in 98% of the power.

I'm not sure about how to red this stuff, it seems a bit contradictory but there is clearly something wrong.
Can anyone help on this ?

Thanks in advance

I also add that, when octane manages to start and does not crash, i get this: zero ram used !
