not to bust your bubble fit, but it wont work.
The 920 as well as any consumer i7 you can buy is a 1 x QPI chip with the second QPI disabled.
You need an expensive 2 x QPI chip for dual communication to work, and those are uber money.
Also not to mention that the dual QPI chips have there memory/qpi divider locked, your hopes at a 4.5 8 core 16thread machine is about 1 yr too earily.
Example when you put a 2xQPI chip inside a X58 Board... im missing 3 options in bios:

the only chip i know which has a remote possibly to do something like that is a W5580, but good luck getting those when there almost 2000 dollars a pop.
And this is coming from experience, i own a gainestown pair chip which Dave (movieman) is happily running for me until such board YOU are looking for comes out for me to buy.
There called Twiddle Dee and Twiddle Dum for now....
