Advanced Chipset Features

DRAM Timing Selectable
This field allows you to select the DRAM timing setting. Setting to [By SPD] enables Max
Memclock (Mhz) automatically to be determined by SPD. Selecting [Manual] allows
users to configure these fields manually. Setting options: [By SPD] , [Manual].
CAS Latency
When the DRAM Timing Control is set to [Manual], this field is adjustable. The field
controls the CAS latency, which determines the timing delay before SDRAM starts a
read command after receiving it. Setting options: [2T], [2.5T], [3T]. [2T] increases
system performance while [3T] provides more stable system performance.
DRAM RAS# to CAS# Delay
When the DRAM Timing Control is set to [Manual], this field is adjustable. 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. Setting options: [2T] to [5T].
DRAM RAS# Precharge
When the DRAM Timing Control is set to [Manual], this field is adjustable. This
setting controls the number of cycles for Row Address Strobe (RAS) to be allowed to
precharge. If insufficient time is allowed for the RAS to accumulate its charge before
DRAM refresh, refreshing may be incomplete and DRAM may fail to retain data. This
item applies only when synchronous DRAM is installed in the system. Setting options:
[2T] to [5T], [Auto].
