How do you know he is trying to run triple channel? He probably has 2x2Gigs and 2x1Gigs. Not very unusual.
I was gonna say - OP is running a P55 system, not an X58. That's a dual channel system.
What I'd want to know is what is the primary storage device on this system - an SSD or an HD? If it's an HD I'd recommend looking at upgrading to an SSD.
