Hi,
I recently started mining using the ethminer (0.9.41 genoil 1.1.7) but it looks that sometimes core of my GPU is off.
Is this just Afterburner error or is something wrong with my card? Temperatures are below 60 degrees C and memory clock speed seems to be OK. While gaming or using my computer for work I haven't got any problems with GPU whatsoever.
You should use another miner than genoil, it's pretty old now, and not updated anymore.
