    DZ77BH-55K code 51 "Allocation of Resources to PCI" with adding new Video Card.




      I just replaced a working PCIe x16 card with a new Sapphire R9 380 4GB x16 Video Card into the x16 slot at can't get past a BIOS code 51.

      Sterilized everything and re-installed 3x in both x16 slots. Repeat BIOS stoppage at code 51 everytime.

      Plenty clean. Plenty of power. Everything physical looks perfect. Can't see any wrong choices in the BIOS vF2.

      Reinstalled old 1GB video card >> boots perfectly.

      Any ideas what may be causing the board to throw a 51 code with installation of a new video card?

      Thanks for access to your expertise.
