Advanced Chipset Features

SDRAM CAS Latency Time
When synchronous DRAM is installed, the number of clock cycles of
CAS latency depends on the DRAM timing. Do not reset this field from
the default value specified by the system designer.
SDRAM Cycle Time Tras/Trc
Select the number of SCLKs for an access cycle.
The choices: 5/7, 7/9 disable.
SDRAM RAS-to-CAS Delay
This field lets 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; slow gives more stable performance. This field
applies only when synchronous DRAM is installed in the system.
