Asrock 970 extreme 4 woes in Processors, Motherboards and Memory Posted December 1, 2011 · Report reply Probably not. It likely shipped with BIOS 1.20 and you need at least BIOS 1.40 for it to work properly with a BD CPU. Do you know anyone with an AM3 CPU you could hijack to flash the BIOS? Looks like I will find out tomorrow. My buddy has a chip that will work so I will take the thing over to his place and test it. Still haven't heard back from asrock, so much for their customer service.
