Adjust CPU FSB Frequency (M Hz)
This item allows you to select the CPU Front Side Bus clock frequency (in MHz).
Adjust CPU Ratio
This item is used to adjust CPU clock multiplier (ratio). It is available only when the
processor supports this function.
Adjusted CPU Frequency (M Hz)
This item shows the adjusted CPU frequency. Read only.
Advance DRAM Configuration
Press to enter the sub-menu and the following screen appears.
DRAM Timing Mode
Selects whether DRAM timing is controlled by the SPD (Serial Presence Detect)
EEPROM on the DRAM module. Setting to [Auto] enables DRAM timings and the
following related items to be determined by BIOS based on the configurations on
the SPD. Selecting [Manual] allows users to configure the DRAM timings and the
following related items manually.
Bank Interleaving
This field selects 2-bank or 4-bank interleave for the installed SDRAM. Disable
the function if 16MB SDRAM is installed.
1T/2T M emory Timing
W hen the Memory Timings is set to [Manual], the field is adjustable. This field
controls the SDRAM command rate. Selecting [1T] makes SDRAM signal control-
ler to run at 1T (T=clock cycles) rate. Selecting [2T] makes SDRAM signal con-
troller run at 2T rate.
SoftWare M emory Hole
In order to improve performance, certain space in memory can be reserved for
ISA peripherals. This memory must be mapped into the memory space below
16MB. W hen this area is reserved, it cannot be cached.
FSB/DRAM Ratio
This setting controls the ratio of CPU FSB Clock & DRAM Frequency to enable the CPU
FSB & DRAM to run at different frequency combinations (non-synchronous overclocking).
Please note that the setting options vary according to the CPU FSB Clock preset.
