Since the Sapphire PC-AM2RX780 is an AMD chipset base board you can use either the BIOS for overclocking or the AMD Overclocking Utility. For the purpose of this review I testing overclocking on both options and ended up with the same result both ways. In the end the Sapphire board did not like any changes at all in the bus speed, not even 201Mhz, but this board was the most liberal I have had with the multiplier, allowing me to raise it up to 16x for a whopping 3.20GHz on the Phenom x4 9850 Black Box. The was achieved only by raising the VCore to 1.45v and Northbridge VID to 1.35v. This is one of the best overclockes I have achieved on this chip which goes to show you how well chipsets are evolving as time goes on.
