Extreme Memory Profile (X.M.P.)
Memory Frequency(Mhz)
The settings under the three items above are synchronous to those under the same items on the Ad-
vanced Frequency Settings menu.
Performance Enhance
Allows the system to operate at three different performance levels.
Standard Lets the system operate at its basic performance level.
Turbo Lets the system operate at its good performance level. (Default)
Extreme Lets the system operate at its best performance level.
DRAM Timing Selectable (SPD)
Quick and Expert allows the Channel Interleaving, Rank Interleaving, Channel A Timing Settings,
and Channel B Timing Settings items 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 1.5V. 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.
Profile VTT Voltage
The value displayed here is dependent on the CPU being used.
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 au-
tomatically configure this setting. (Default: Auto)
(Note) This item is present only if you install a memory module that supports this feature.
