& Adjacent Cache Line Prefetch
Allows you to determine whether to enable the adjacent cache line prefetch mechanism that lets the
processor retrieve the requested cache line as well as the subsequent cache line. (Default: Auto)
& ExtremeMemoryProle(X.M.P.)
(Note)
Allows the BIOS to read the SPD data on XMP memory module(s) to enhance memory performance when
enabled.
Disabled Disables this function. (Default)

Prole2
(Note)
  UsesProle2settings.
& System Memory Multiplier
Allows you to set the system memory multiplier. Auto sets memory multiplier according to memory SPD
data. (Default: Auto)
& Memory Ref Clock
Allows you to manually adjust the memory reference clock. (Default: Auto)
& Memory Odd Ratio (100/133 or 200/266)
Enabled allows Qclk to run in odd frequency. (Default: Auto)
& Memory Frequency (MHz)

When using a non-XMP memory module or ExtremeMemoryProle(X.M.P.) is set to Disabled, the value
isdisplayedaccordingtoyourmemoryspecication.WhenExtremeMemoryProle(X.M.P.) is set to
Prole1 or Prole2, the value is displayed according to the SPD data on the XMP memory.
