Chipset Features Option - ECS P6SEP-Me User Manual

Chipset Features Option

This option displays a table of items that define critical timing parameters of the
mainboard components including the CPU, the memory, and the system logic.
As a general rule, you should leave the items on this page at their default values unless
you are very familiar with the technical specifications of your system hardware. If you
change the values, or load the optimum settings, you may introduce fatal errors or
recurring instability into your system. The item list below shows only the default
values for some items.
Auto Configuration
Leave this item at the default value enabled. Auto configuration installs preset default
values for many of the timing parameters for the system.
RAS Pulse Width Refresh
RAS Precharge Time
RAS to CAS Delay
These items install the settings for the Row Address Strobe (RAS) and the Column
Address Strobe (CAS). The RAS and CAS determine the timing of the system's access
to the main memory. We recommend that you leave these items at the default values.
ISA Bus Clock Frequency
This item sets the timing for the ISA bus by dividing the frequency of the PCI bus.
The PCI bus is usually set to 33 MHz, and we recommend that you divide this by four
to set the ISA bus frequency.
