Re: Hardware/Voltage monitor for GFX5700
Yes, it's possible, maybe even likely, that you have that driver warning from high heat, and not low power.
I got rid of the "insufficient power" warning on a friend's machine last summer by opening his bad-airflow case and aiming a room fan into it. His 430W Antec PSU was fine. It was exclusively heat that caused the drivers to give that warning to him.
I used to drive a Heisenberg, but whenever I'd glance at the speedometer, I'd get lost.
