Advanced DRAM Control 1
Press <Enter> and the following sub-menu appears:
System Performance
This setting particularly provided by SiS gives the proper suggestion for user to
set timing. The Timings programmed into this register are dependent on the
system design. Slower rates may be required in certain system designs to
support loose layouts or slower memory. Setting options: [Safe Mode], [Normal
Mode], [Fast Mode], [Turbo Mode], [Ultra Mode].
CAS Latency Setting
The field controls the CAS latency, which determines the timing delay before
SDRAM starts a read command after receiving it. Setting options: [By SPD], [3T],
[2.5T], [2T]. [2T] increases system performance while [3T] provides more stable
system performance. Setting to [By SPD] enables DRAM CAS# Latency
automatically to be determined by BIOS based on the configurations on the SPD
(Serial Presence Detect) EEPROM on the DRAM module.
MA 1T/2T Select
This setting controls the SDRAM command rate. Selecting [Auto] allows SDRAM
signal controller to run at 1T (T=clock cycles) rate. Selecting [1T] makes SDRAM
signal controller run at 2T rate. 1T is faster than 2T. Setting options: [Auto], [2T],
[1T].
