SPD.
SPD (Serial Presence Detect) is located on the
memory modules, BIOS reads information coded in
SPD during system boot up.
SDRAM CAS# Latency When synchronous DRAM is installed, the number
of clock cycles of CAS latency depends on the
DRAM timing. Do not reset this field from the de-
fault value specified by the system designer.
SDRAM RAS#
If an insufficient number of cycles is allowed for the
Precharge
RAS to accumulate its charge before DRAM refresh,
the refresh may be incomplete and the DRAM may
fail to retain data. Fast gives faster performance;
and Slow gives more stable performance. This field
applies only when synchronous DRAM is installed
in the system.
