C5 code on B650D4U

   I just picked up a B650D4U to build a server with.  When I turn it on, it doesn't fully POST.  Looking at the Dr. Debug codes, I see 15 followered by C5 where it stops.  Never get VGA output though it'll take the display out of low power mode, nothing ever comes up just black screen.

The manual doesn't list C5, but says 15 is something like northbridge init.

	C5 should be memory related error, try shuffling single ram stick in different slots
