I've got Asus P7P55D-E 6g board, and Gigabyte GA-P55A-UD4P board, and i looked at gigabyte ga-p55-ud4p/ non-6g, and all of them can use all the 1156 cpus. btw, it was cool to research thr socket, and cpus, and boards too, to see that 1156 socket can run 1156 cpu, period, and i trusted newegg, but that was a loop, it seems. Like the egg tells me, we don't have tech knowledge here / omg, i'm sorry. But, they must Know, cuz they're newegg-ing. Have an Eggcellent day (mr. egg on the face (haha). cheers to tom's peoples.
