since the chipset came out AFTER the CPU, then it is inconceiveable for one to NOT recognize it out of the box... you go by release dates on those things...
if the CPU was released before the mobo, then the mobo will always recognize it.
if the mobo was released before the CPU, then a bios upgrade might be needed (unless your specific unit was manufactured after the CPU was released, using the older design, but a newer bios)
