DRAM 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.
DRAM RAS# PRECHARGE:
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.

determines
