Hi newcomer and welcome to the Tom's hardware forum.
You mobo only support that processor with the F3 BIOS version. So, u need upgrade your BIOS.
Download the F3 BIOS version from here
and boot from a CD or flash drive to upgrade the BIOS. BUT 1st read the process about upgrade your BIOS on the manual of the mobo, a bad update BIOS can kill your mobo.
