Download this program and run it and see what the results are. Your BIOS shot shows the ram is recognized, but the slot is disabled. Try removing the ram and cleaning out the slot with compressed air. Also insert and remove the ram a few times to clean the contacts. You can also run this test to see if the new ram is good.Run the test using memtest found here.
I see there is no bios update that would apply to this situation. Also check the ram settings in the bios to make sure they're in sync. Last scenario is bad ram slots on the mobo.
