RAS to CAS
Use this feature 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. Fast speed offers faster performance while slow 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: Auto, 4, 8.
DRAM Command Rate
This setting controls the SDRAM command rate. Selecting 1T allows
SDRAM signal controller to run at 1 clock cycle rate. Selecting 2T makes
SDRAM signal controller run at 2 clock cycle rate. 1T is faster than 2T.
Setting options: 2T, 1T.
Current Host (FSB) Clock/DRAM Frequency
These features show the current host clock and DRAM clock frequency.
(read only)
Current DDR Frequency
This read-only feature will show up only if DDR is installed.
