Just got a free upgrade to a brand new Q9550 from my old Q9400
and i can see it does 4.0 a lot easier than even my last one on this board..

although i gotta say there appear to be boot issues with this particular UD3R, almost like it doesn't wanna boot unless you set EXACTLY the right settings, took 25 tries once and had to remove the CMOS battery and even then....

Gonna give it's little brother the EP45 UD3L a try this afternoon....either way it's good to have a back up board...
and the 12 mb of cache doesn't hurt either....
