Chapter 3 BIOS Description
Max Memclock (MHz) (Default: Auto)
User can place an artificial memory clock limit on the system. Memory is pre-
vented from running faster than this frequency.
1T/2T Memory Timing (Default: Auto) (Optional)
This item 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.
CAS# Latency (Tcl) (Default: Auto)
This item controls the CAS latency, which determines the timing delay (in
clock cycles) before SDRAM starts a read command after receiving it.
RAS# to CAS# delay (Trcd) (Default: Auto)
When DRAM is refreshed, both rows and columns are addressed separately.
This setup item allows you to determine the timing of the transition from RAS
(row address strobe) to CAS (column address strobe). The less the clock cycles,
the faster the DRAM performance.
CPU Thermal-Throttling (Default: 50.0%)
This item is used to specify the CPU speed (at percentage) to slow down the
CPU when it reaches the predetermined overheated temperature.
System BIOS Cacheable (Default: Disabled)
Select “Enabled” to allow catching of the system BIOS which may improve per-
formance. If any other program writes to this memory area, a system error
may result. The available setting values are: Disabled and Enabled.
