Do you make this stuff up as you go? As far as I know they are triple channel memory controllers, just like the desktop variant. I've seen amateurs make mistakes like this before.

*sigh* I'll point you in the right direction by telling you that DP Xeon chips have two QPI connects vs. the i7's one.

QPI is not memory. There are 2 QPI channels so that the two sockets with processors in them can form a triangle with the IOH.
