Auto Configuration; Dram Leadoff Timing; Dram Write Burst Timing; Dram Timing - MSI MS-5156 Manual

Auto Configuration

Choosing Enabled (default) will automatically configure chipset
features using default settings. Choose Disable to customize setup.

DRAM Timing

Sets the DRAM speed at 70ns (default) or 60ns. It will set the
speed of the EDO/FP DRAM.

DRAM Leadoff Timing

To be able to change the setting, Auto configuration must be
disable. If the Bus Clock is 75MHz set it to 11/7/4, and if the Bus Clock is 66/
60/55 MHz set it to 10/6/4. Default setting is 10/6/4.
DRAM Read Burst (EDO/FP)
Under Auto config. the BIOS will identify which type of DRAM is
being used. Choose the setting accordingly. To customize, use this option
which sets the Read Burst time for accessing the DRAM. The timing used
depends on the type of DRAM and access time being used. The settings are
x222/x333, x333/x444, or x444/x444.
Note: If the user chooses DRAM Read Burst (EDO/FP): x333/x444 it signi-
fies that:
a. 60ns EDO with 75 MHz Bus Clock is set at x333, if the Bus Clock is
66/60/55 MHz, then it is set at x222.
b. 60ns FP with 75 MHz is set at x444, if the Bus Clock is 66/60/55,
then it is set at x333.
c. 70ns EDO and FP DRAM must increase the burst time. So you
must set x222 to x333 and x333 to x444.

DRAM Write Burst Timing

This option chooses the Write Burst Timing for accessing DRAM.
See: DRAM Read Burst Option. Choose x222/x333/x444.
