BIOS Setup
166MHz
The
memory clock speed will run at 333MHz.
200MHz
The
memory clock speed will run at 400MHz.
DRAM Timing
This field is used to select the timing of the DRAM.
Auto 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 “Auto By SPD”, select this option.
However,
compatibility problems may occur with some
DRAMs. If you encounter any problems, set this
field to “Auto By SPD” or “Manual”.
Ultra
If you want the system to run at a speed faster
than “Turbo”, select this option.
However, com-
patibility problems may occur with some
DRAMs. If you encounter any problems, set this
field to “Auto By SPD” or “Manual”.
Manual
This option allows you to manually select the
options in the “SDRAM CAS Latency” to “REF
to ACT/REF(Trfc)” fields. The system will run ac-
cording to the settings in these fields.
SDRAM CAS Latency
This field is used to select the clock cycles for the CAS latency.
Bank Interleave
The options are 2 Bank, 4 Bank and Disabled.
Precharge to Active (Trp)
The options are 2T, 3T, 4T and 5T.
