to be configurable. Options are: Auto (default), Quick, Expert.
 &Profile DDR Voltage
 When using a non-XMP memory module or Extreme Memory Profile (X.M.P.) is set to Disabled, this item 
will display as 1.50V. When Extreme Memory Profile (X.M.P.) is set to Profile1 or Profile2, this item will 
display the value based on the SPD data on the XMP memory.
 &Channel Interleaving
 Enables or disables memory channel interleaving. Enabled allows the system to simultaneously access 
different channels of the memory to increase memory performance and stability. Auto lets the BIOS 
automatically configure this setting. (Default: Auto)
 &Rank Interleaving
 Enables or disables memory rank interleaving. Enabled allows the system to simultaneously access different 
ranks of the memory to increase memory performance and stability. Auto lets the BIOS automatically 
configure this setting. (Default: Auto)
(Note)  This item is present only when you install a CPU and a memory module that support this feature.

This sub-menu provides memory timing settings for each channel of memory\
. The respective timing setting 
screens are configurable only when DRAM Timing Selectable is set to Quick or Expert. Note: Your system 
may become unstable or fail to boot after you make changes on the memory timings. If this occurs, please reset 
the board to default values by loading optimized defaults or clearing th\
e CMOS values.

2-5 BIOS Features
 &Boot Option Priorities
 Specifies  the  overall  boot  order  from  the  available  devices.  For  example,  you  can  set  hard  drive  as  the 
first priority (Boot Option #1) and DVD ROM drive as the second priority (Boot Option #2). The list only 
displays the device with the highest priority for a specific type. For example, only hard drive defined as the 
first priority on the Hard Drive BBS Priorities submenu will be presented here.
 Removable storage devices that support GPT format will be prefixed with "UEFI:" string on the boot device 
list. To boot from an operating system that supports GPT partitioning, select the device prefixed with "UEFI:" 
string.
 Or if you want to install an operating system that supports GPT partitioning such as Windows 7 64-bit, select 
the optical drive that contains the Windows 7 64-bit installation disk and is prefixed with "UEFI:" string.
