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.
BIOS Setup
Lets the system operate at its basic performance level.
Lets the system operate at its good performance level. (Default)
