Award BIOS Setup Utility
DRAM Timing
This field is used to select the timing of the DRAM.
By SPD
The EEPROM on a DIMM has SPD (Serial
Presence Detect) data str ucture that stores
information about the module such as the memory
type, memory size, memory speed, etc. When this
option is selected, the system will run according to
the information in the EEPROM. This option is the
default setting because it provides the most stable
condition for the system. The “SDRAM C AS
Latency” to “DRAM Command Rate” fields will
show the default settings by SPD.
Manual
If you want a better performance for your system
other than the one “by SPD”, select “Manual”. Then
select the best option in the “SDRAM C AS
Latency” to “DRAM Command Rate” fields.
SDRAM CAS Latency
The default setting is 3 which is 3 clock cycles for the CAS latency.
