Problem: two memory slots showing as not enabled in BIOS.
I recently installed a P55-UD3R board with 4 2GB sticks of g.skill 1600 (PC3 12800) F3-12800CL8D-4GBRM. As I was only running XP32bit at the time didnt notice anything wrong until now installed Win7 64bit and expecting 8GB to show.
BIOS has been updated to F5 w/optimized settings and I've tried each memory stick by itself in slot 1 all ok.
With one in slot 1 and 2nd in slot 3 system shows only 2GB. If I add the other two sticks slots 3 and 4 show as not enabled giving me only 4GB.
I've searched various forums and really dont want to send the board or memory back so hoping there is a "magic" setting that fixes the issue. Thoughts?
