Advanced Chipset Features
These items define critical timing parameters of the mainboard. You should
leave the items on this page at their default values unless you are very
familiar with the technical, specifications of your system hardware. If you
change the values incorrectly, you may introduce fatal errors or recurring
instability into your system.

The value in this field depends on performance parameters of the
installed memory chips ( DRAM ). Don't change the value from the
factory setting unless you install new memory that has a different perfor-
mance rating than the original DRAMs.

CAS Latency Time (2.5)
When synchronous DRAM is installed, the number of clock cycles of
CAS latency depends on the Dram timing. Don't reset this field from the
default value specified by the system designer.

The precharge time is the number of cycles it takes for DRAM to accu-
mulate its charge before refresh.
