Hello all

Since most people don't post solutions that often, I thought I'd post that it appears my issue where 8 GB was only available out of 16GB installed was solved when loading the modded P67X-UD3-B3 U1B BIOS over the normal U1B. I loaded optimized defaults and rebooted and got all 16 GB of RAM. It may be worth trying to use that BIOS if you have issues with RAM. I just wish I'd tried it before I went through two sets of RAM trying to get it working... Now I have RAM to try to return or sell :/
