DRAM RAS# to CAS# Delay
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. Fast speed offers faster performance while slow speed offers
more stable performance. Settings:
4, 3
,
2
(clocks).
DRAM RAS# Precharge
This item controls the number of cycles for Row Address Strobe (RAS) to be
allowed to precharge. If insufficient time is allowed for the RAS to accumu-
late its charge before DRAM refresh, refresh may be incomplete and DRAM
may fail to retain data. This item applies only when synchronous DRAM is
installed in the system. Available settings:
4, 3
,
2
(clocks).
Memory Frequency For
Use this item to configure the clock frequency of the installed DRAMs.
Options:
Auto, DDR 266, DDR333, DDR320, DDR400
.
DRAM Data Integrity Mode
Select
ECC
(Error-Correcting Code) or
