Award BIOS Setup Utility
Manual If you want better system performance other than
the one “by SPD”, select “Manual” then select the
best option in the “CAS Latency Time” to “DRAM
RAS# Precharge” fields.
3.1.3.2 CAS Latency Time
This field is used to select the local memory clock periods.
3.1.3.3 Active to Precharge Delay
The options are 5, 6, 7 and 8.
3.1.3.4 DRAM RAS# to CAS# Delay
The options are 2, 3 and 4.
3.1.3.5 DRAM RAS# Precharge
This field controls RAS# precharge (in local memory clocks).
3.1.3.6 Memory Frequency For
This field is used to select the memory clock speed of the DIMM.
The system board supports DDR333 or DDR400 when using
800MHz FSB CPU. DDR333 will run at 320MHz memory frequency
when used with 800MHz FSB CPU. Under such circumstance, make
sure this field is set to Auto or DDR320.
Refer to chapter 1 (System Memory section) for detailed
specification of the memory supported by the system board.
3.1.3.7 System BIOS Cacheable
When this field is enabled, accesses to the system BIOS ROM
addressed at F0000H-FFFFFH are cached, provided that the cache
controller is enabled. The larger the range of the Cache RAM, the
higher the efficiency of the system.
