So, I recently got an Asus DCIItop.
To start it off, this card has two 8 pin connectors instead of a six pin and an eight pin.
The problems start when I increase the energy setting to +20% in the catalyst control centre.
When I run Furmark on stock, I get an effective 43 frames avarage.
When I run it at stock and increase the energy to +20%, my frames rocket up to an effective 60+ frames. (clock sliders fully open reches 68 frames)

When the energy slider (only the energy slider) is set to +20%, temperatures in furmark reach dramatic heights very fast (32C to 86C+ in 7 seconds).
When the temps reach 78C, I get black stripes and major stutters, when it reaches 80C, I get distorted screen tearing, when it reaches 84C, I don't recognise anything on screan.
At 86C, the PC shuts itself down.

When I run everything at full throttle in CCC (energy and clock settings fully open), my PC only freezes when the card reaches 86C.
I can hear the card throttling down and nothing will function after that, I have to manually re-boot the system.

So my problem is - whenever I up the energy setting, this card's performance increases with 50% in furmark, but my pc crashes.
I wasn't able to test the card in newer games such as skyrim or anno 2070, but at full load (everything slid to the top) a game like the Sims 3 will run just smoothly.

Whenever I get home and my pc is working again I will test it with the newer games and see if it gives me any trouble.

Anyhoo, to the point-
does anyone know why the energy slider is giving me so much trouble in furmark?
