AWARD ® BIOS Setup
3-15
RAS Pulse
This setting allows you to select the number of DRAM clock cycles
allotted for the RAS pulse width, according to DRAM specifications.
The less the clock cycles, the faster the DRAM performance. Settings:
6T, 5T and Auto.
RAS to CAS
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. Settings:
3T, 2T and Auto.
Burst Length
This setting allows you to set the size of Burst-Length for DRAM.
Bursting feature is a technigue that DRAM itself predicts the address
of the next memory location to be accessed after the first address is
accessed. To use the feature, you need to define the burst length,
which is the actual length of burst plus the starting address and allows
internal address counter to properly generate the next memory location.
The bigger the size, the faster the DRAM performance. Settings: 4, 8
and Auto.
DRAM Command Rate
This setting controls the DRAM command rate. Selecting 1T allows
DRAM signal controller to run at 1T (T=clock cycles) rate. Selecting
2T makes DRAM signal controller run at 2T rate. 1T is faster than 2T.
Settings: 2T and 1T.
Current Host (FSB) Clock, Current DRAM/DDR Frequency
These items display current CPU host clock, DRAM/DDR clock
frequency. Current DDR Frequency appears only when DDR DRAMs
are installed.
