Manual
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 DDR266, 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 Memor y section) for detailed
specification of the memory supported by the system board.
3.1.3.7 DRAM R/W Timing
This field is used to select the read/write cycle speed. Select "Fast" if
you want the system to run at a faster cycle speed.
If you want better performance for your system
other than the one "by SPD", select "Manual" then
select the best option in the "CAS Latency Time"
to "DRAM RAS# Precharge" fields.
