Chipset Features à SDRAM CAS Latency
Chipset Features à SDRAM RAS# to CAS# Delay
SDRAM CAS These are timing of SDRAM CAS Latency and RAS
Latency
to CAS Delay, calculated by clocks. They are
important parameters affects SDRAM performance,
2T
default is Auto. If you install DIMMs with SPD and
3T
set this item to Auto, BIOS will automatically detect
Auto
your DIMMs and then set to a appropriate timing; If
you use DIMMs without SPD and set this item to
Auto, BIOS will set it to 3/3.To make sure all of these
settings in BIOS are correct, it is recommended to
use DIMMs with SPD.
Chipset Features à SDRAM RAS# Precharge

The RAS Precharge means the timing to inactive
precharge RAS and the timing for DRAM to do precharge
before next RAS can be issued. RAS is the address
2T
latch control signal of DRAM row address. The
3T
default setting is Auto.
