SDRAM RAS-to-CAS Delay (Auto)
This sets the relative delay between the Row Address Strobe
(RAS) and the Column Address Strobe (CAS). Select the RAS
to CAS delay time in HCLKs of 2/2 or 3/3. The value is set at
the factory depending on the DRAM installed. Do not change
the values in this field unless you have changed the specifica-
tions of the installed DRAM or the installed CPU.
SDRAM RAS Precharge Time (Auto)
DRAM must continually be refreshed or it will lose its data. This
option allows you to determine the number of CPU clocks allo-
cated for the Row Address Strobe (RAS) to accumulate its
charge before the DRAM is refreshed. If insufficient time is a l-
lowed, refresh may be incomplete and data lost.
System/Video BIOS Cacheable (Enabled)
These items allow the video and system to be cached in
memory for faster execution. Leave these items at the default
value for better performance.
CPU Latency Timer (Enabled)
This item sets a timing parameter for CPU access. Since the
CPU timing is determined by the system hardware, leave this
item at the default value.
Delayed Transaction (Enabled)
If the chipset has an embedded 32-bit write buffer, to support
delay transaction cycles, you can enable this item to provide
compliance with PCI Ver. 2.1 specifications. We recommend
that you leave this item at the default value.
