User`s manual

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: 2T, 3T and 4T.

SDRAM 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.
