BIOS Setup
Current FSB Frequency
This field will show the detected FSB of the CPU.
Current DRAM Frequency
This field will show the detected frequency of the DDR SDRAM
DIMM.
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 option is selected, the system will run ac-
cording to the information in the EEPROM. This
option is the default setting because it provides
the most stable condition for the system.
133 MHz The memory clock speed will run at 266MHz.
166 MHz The memory clock speed will run at 332MHz.
200 MHz The memory clock speed will run at 400MHz
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 option is selected, the system will run ac-
cording to the information in the EEPROM. This
option is the default setting because it provides
the most stable condition for the system.
Turbo If you want the system to run at a speed faster
than “By SPD”, select this option. However, com-
patibility problems may occur with some
DRAMs. If you encounter any problems, set this
field to “By SPD” or “Manual”.
