Advanced Chipset Features Setup
Figure 8.4. Advanced Chipset Features Setup
This section allows you to configure the system based on the specific features of the installed chipset.
This chipset manages bus speeds and access to system memory resources, such as DRAM and the
external cache. It also coordinates communications between the conventional ISA bus and the PCI bus.
It must be stated that these items should never need to be altered. The default settings have been chosen
because they provide the best operating conditions for your system. The only time you might consider
making any changes would be if you discovered that data was being lost while using your system.

DRAM Timing Selectable
The value in this field depends on performance
parameters of the installed memory chips (DRAM).
Do not change the value from the factory setting
unless you install new memory that has a different
performance rating than the original DRAMs

CAS Latency Time
When synchronous DRAM is installed, the number
of clock cycles of CAS latency depends on the DRAM
timing. Do not reset this field from the default
value specified by the system designer.
