I have two systems board X7DBE, I see it says that it can support Harpertown /Clovertown processor. http://www.supermicro.com/products/motherboard/xeon1333/5000P/X7DBE.cfm

Is there a compatibility list that lets me know which Processors it accepts and or if it needs a bios update to run an X series Chip? I have a rev2.0 board. I am running E5404s right now and I want to upgrade. Can this board run the x series chips as well? I know the only difference is the Power consumption, but I want to confirm.
