yes guiminer sees 3 GPUs, catalyst control center sees 1 primary GPU and 2 additional GPU are active, CPU mining is not selected. It just slowly over time falls behind the other 2 GPUs 

Hello all, im fairly new to bitcoin mining. But i have stumbled upon an issue i think is worth posting about, because i have no idea what would cause it.

As you can see from the picture below, all 3 of my 5830's have been mining for about 20min, but for some reason gpu 2 isnt quite up to speed with 1 & 3. Is this a problem anyone else is having or is it some kind of settings issue?


settings are as follows

aggression = 7
phatk kernel
worksize 256
