guys, guys, thats whats officially supported... im sure you can use more than 24gb even on a single cpu 1366 server board that has the required mem slots for it.

oh and some here said it is equipped with dual x58, im not too sure about that.
its possible to use a single x58 ioh for 2 cpus, and more than that, its even possible to do this with cpus that only have 1 qpi link!
whether intel supports it and allows it is another thing... but in theory you could actually plug in two 920s into a dual qpi link x58 equipped board.
there would be no direct cpu to cpu qpi link, but so what? yorkfield doesnt have a direct link from cpu to cpu and talks through the chipset and it performs amazingly well...
