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.
This field allows you to select a CAS Precharge delay
timing.
Choices are: 7; 6; 5
This field lets you insert a timing delay between the
Delay CAS and RAS strobe signals, used when DRAM is
written to, read from, or refreshed. Fast gives faster
performance and Slow gives more stable
performance. This field applies only when synchronous
DRAM is installed in the system.
The Choices: 2; 3
If an insufficient number of cycles is allowed for the
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.
