DRAM CAS Latency
When synchronous DRAM is installed, the number of clock cycles of CAS latency depends on the
DRAM timing. The settings are: 2T and 2.5T.
RAS Precharge Time
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 date. Fast gives faster
performance; and Slow gives more stable performance. This field applies only when synchronous
DRAM is installed in the system. The settings are: 2T, 3T and 4T.
RAS to CAS Delay
This field let's you insert a timing delay between the 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
settings are: 6T, 7T and 8T.
