DDR DRAM Clock
This field is used to select the clock speed of the DDR SDRAM
DIMM.
By SPD
The EEPROM on a DIMM has SPD (Serial Pres-
ence Detect) data structure that stores informa-
tion about the module such as the memory type,
memory size, memory speed, etc. When this op-
tion 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.
200 MHz
The
memory clock speed will run at 200MHz
DDR.
266 MHz
The
memory clock speed will run at 266MHz.
DDR
DRAM Timing
This field is used to select the timing of the DRAM.
By SPD
The EEPROM on a DIMM has SPD (Serial Pres-
ence Detect) data structure that stores informa-
tion about the module such as the memory type,
memory size, memory speed, etc. When this op-
tion 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 “DRAM CAS
Latency” to “Active to CMD (Trcd)” fields will
show the default settings by SPD.
Manual
If you want better performance for your system
other than the one “by SPD”, select “Manual”
then select the best option in the “DRAM CAS
Latency” to “Active to CMD (Trcd)” fields.
DRAM CAS Latency
This field is used to select the clock cycle of the SDRAM CAS
latency time. The option selected specifies the time before
SDRAM starts a read command after receiving it.
