4.3.3.6 SDRAM RAS# to CAS# Delay
This option controls the number of SCLKs (SDRAM Clock) from a row activate command
to a read or write command. If your system installs good quality of SDRAM, you can set
this option to “2 SCLKs” to obtain better memory performance. Normally, the option will be
set to “3 SCLKs”.
