Well i think that you are 50% right , about the bug .
I did not get any response from MSI .
So I did flashed the card with one similar firmware Version 5.40.02.15.02
Made by NVIDIA , well nothing changed , the problem is there too.
I am confused, as i have try everything and anything, in the Bios of my board .
Every possible, power management configuration.
No I am looking to Google, trying to find , NVIDIA’s 6800 cards power management specs .
Honestly I am trying to find every possible solution, so to not RMA the card, because it works so damn well with games..
