CPU Technology Support
Press <Enter> to enter the submenu, that shows the technologies that the in-
stalled CPU supported.
Intel EIST
The Enhanced Intel SpeedStep technology allows you to set the performance
level of the microprocessor whether the computer is running on battery or AC
power. This field will appear after you installed the CPU which support SpeedStep
technology.
Adjust CPU FSB Frequency (MHz)
This item allows you to adjust the CPU FSB frequency.
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 (MHz)
It shows the adjusted CPU frequency (FSB x Ratio). Read-only.
MEMORY-Z
Press <Enter> to enter the submenu.
DIMM1/2 Memory SPD Information
Press <Enter> to enter the submenu, that displays the informations of installed
memory.
Advance DRAM Configuration
Press <Enter> to enter the submenu.
DRAM Timing Mode
Selects whether DRAM timing is controlled by the SPD (Serial Presence De-
tect) EEPROM on the DRAM module. Setting to [Auto By SPD] 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.
CAS Latency (CL)
When the DRAM Timing Mode sets to [Manual], the field is adjustable. This
controls the CAS latency, which determines the timing delay (in clock cycles)
before SDRAM starts a read command after receiving it.
tRCD
When the DRAM Timing Mode sets to [Manual], the field is adjustable. When
DRAM is refreshed, both rows and columns are addressed separately. This
setup item allows you to determine the timing of the transition from RAS (row
address strobe) to CAS (column address strobe). The less the clock cycles, the
faster the DRAM performance.
tRP
When the DRAM Timing Mode sets to [Manual], the field is adjustable. This
item controls the number of cycles for Row Address Strobe (RAS) to be al-
lowed to precharge. If insufficient time is allowed for the RAS to accumulate its
charge before DRAM refresh, refreshing may be incomplete and DRAM may
