RAS# to CAS# Delay

This item allows you to insert a timing delay between the CAS and RAS

strobe signals, used when DRAM is written to, read from, or refreshed.

The setting [2] gives faster performance and [3] gives more stable

performance. This item applies onl when synchronous DRAM is intalled

in the system.

RAS# Precharge

If an insufficient number of cycles is allowed for the RAS to accumulate

its charge before DRAM refresh, the refresh may be incomplete and the

DRAM may be fail to retain data. The setting [2] gives faster performance

and [3] gives more stable performance. This item applies onl when

synchronous DRAM is intalled in the system.

DRAM Data Integrity Mode

This item allows you to select the [Non-ECC] or [ECC] (Error-Checking

and Correcting), according to the type of installed RDRAM.

DRAM Frequency

This item allows you to set the clock frequency of the DRAM installed.

Available options are [PC100], [PC133] and [Auto]. Default value is

[Auto].

Memory Hole at 15M-16M

This item allows you to reserve an address space for ISA expansion

cards that require it. Available options are [Enabled] and [Disabled].

Default value is [Disabled].

Delayed Transaction

The chipset has an embedded 32-bit posted write buffer to support delay
