******** DRAM Performance Control ********
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. |
Extreme Memory Profile (X.M.P.) (Note)
Allows the BIOS to read the SPD data on XMP memory module(s) to enhance memory performance when enabled.
Disabled
Profile1 
Profile2
(G)MCH Frequency Latch
Allows you to fix the chipset frequency at system bootup. Options for adjusting memory multiplier below may differ according to the fixed frequency. Options are: Auto (default), 200MHz, 266MHz, 333MHz, 400MHz.
System Memory Multiplier (SPD)
Allows you to set the system memory multiplier. Options are dependent on CPU FSB and the (G)MCH Frequency Latch settings. Auto sets memory multiplier according to memory SPD data. (Default: Auto)
Memory Frequency (Mhz)
The first memory frequency value is the normal operating frequency of the memory being used; the second is the memory frequency that is automatically adjusted according to the CPU Host Frequency (Mhz) and System Memory Multiplier settings.
DRAM Timing Selectable (SPD)
Manual allows all DRAM timing control items below to be configurable.
Options are: Auto (default), Manual.
(Note) This item appears only if you install a memory module that supports this feature.
