CAS Latency Time
When synchronous DRAM is installed, the number of clock cycles
of CAS latency depends on the DRAM timing. The choices: 1.5, 2,
and 2.5.
Active To Precharge Delay
Select the operating system that is active to precharge delay. The
choices: 5, 6, 7.
DRAM RAS# to CAS# Delay:
You can select RAS to CAS Delay time in HCLKs of 2/2, 3/3 or 4/4.
The system board designer should set the values in this field,
depending on the DRAM installed. Do not change the values in
this field unless you change specifications of the installed DRAM
or the installed CPU. The choices: 2, 3.
DRAM RAS# Precharge:
If an insufficient number of cycles are allowed for the RAS to accu-
mulate its charge before DRAM refresh, the refresh may be
incomplete and the DRAM may fail to retain data. Fast gives faster
performance; and Slow gives more stable performance. This field
applies only when synchronous DRAM is installed in the system.
The choices: 2, 3.
Memory Frequency For
You can use this item to select operating frequency for the main
system memory. The choices: Auto, DDR266.
System BIOS Cacheable
Selecting “Enabled” allows caching of the system BIOS ROM at
F0000h-FFFFFh, resulting in better system performance. How-
ever, if any program writes to this memory area, a system error
may result. The choices: Enables, Disabled
