I have a ASUS CG5275, and I think it has a Asus P7H55-M motherboard, and I bought a Intel Xeon x3470 for it, and I am currently trying to update the bios to make sure the CPU is compatible, but when I got to the Asus site and onto the P7H55-M bios place to update it, all the bios in there aren't compatible. Is there a reason for this or do I have the wrong motherboard?
