Are you absolutely sure? From various sources I've heard (and seen) that the difference in performance between dual and triple channel is close to nothing. Actually, I am not quite sure yet, because the extra channel should be adding much more bandwidth than the 500MB's I've seen (DDR3 @ 933MHz, exact same system settings). It's either Lavalys Everest that screws up, although I'm not likely to believe that, or something in the bios/motherboard design of the Intel reference motherboard is making the triple channel run at dual channel, which also would surprise me.

What are the possible underlying causes that make people report a lack of performance gain going from dual channel to triple channel? Software/hardware?
