allotted for the RAS pulse width, according to DRAM
specifications. The less the clock cycles, the faster the DRAM
performance. Settings: 6T, 5T, Auto.
RAS to CAS
This field allows you to set the number of cycles for a timing delay
between the CAS and RAS strobe signals, used when DRAM is
written to, read from or refreshed. Faster speed offers faster
performance while slower speed offers more stable performance.
Settings: 3T, 2T, Auto.
Burst Length
This setting allows you to set the size of Burst-Length for DRAM.
Bursting feature is a technique 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, Auto.
DRAM Command Rate
This setting controls the SDRAM command rate. Selecting 1T allows
SDRAM signal controller to run at 1T (T=clock cycles) rate. Selecting 2T
makes SDRAM signal controller run at 2T rate. 1T is faster than 2T.
Setting options: 1T, 2T.
Current Host(FSB) Clock, Current DRAM Frequency, Current DDR
Frequency
These items show the current clock frequency of Front Side Bus and
installed DRAM.
