as per your :
[ 0.000000] Your BIOS doesn't leave a aperture memory hole
[ 0.000000] Please enable the IOMMU option in the BIOS setup
[ 0.000000] This costs you 64 MB of RAM
...
[ 0.338295] mtrr: your CPUs had inconsistent variable MTRR settings
[ 0.338296] mtrr: probably your BIOS does not setup all CPUs.

Hence, as per http://support.asus.com/download.aspx?SLanguage=en&m=M4A89GTD%20PRO/USB3&os=29 an update is available for your BIOS (3029). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and just provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Thank you for your understanding.
