Hi all, I finished up a new build last week and have been getting Arch all configured. I noticed last night that although the BIOS is seeing all 32G of ram, Arch is only seeing 16G (using (2) 16G sticks). I tried booting into and Ubuntu live cd as well as Memtest86 and those both only show 16G as well. For sanity I also ran
uname -a to be sure I installed 64 bit. All good there. I also updated the BIOS and the system boots fine on either stick.
Any help greatly appreciated.
