Chipset Features Setup
Auto Configuration
The default setting of the optimal timings for items 3 through 7 for 60ns EDO DRAM
modules.
EDO DRAM Speed Selection
This item set the EDO DRAM Read/Write timings that the system uses. When item of
"Auto Configuration" is disabled, this item will not show up.
EDO CASx# MA Wait State
The board designer may elect to insert one additional wait state before the assertion of the
first CASx# for page hit cycles, thus allowing one additional clock of MA setup time to
the CASx# for the leadoff page hit cycle. Do not change from the manufacturer's default
unless you are getting memory addressing errors.
EDO RASx# Wait State
The board designer may elect to insert one additional wait state before RASx# is asserted
for row misses, thus allowing one additional MAX [13:0] setup time to RASx# assertion.
This field applies only if EDO DRAM is installed in the system.
SDRAM RAS-to-CAS Delay
This field lets you control the number of DCLKs between a Row Activate command and a
read or write command.
SDRAM RAS Precharge Time
The precharge time is the number of cycles it takes for the RAS to accumulate its charge
before DRAM refresh. If insufficient time is allowed, refresh may be incomplete and the
DRAM may fail to retain data. This field applies only if synchronous DRAM is installed
in the system.
