Frequency/Voltage Control
Spread Spectrum
This item allows you to enable or disable the spread spectrum modulation.
Ø The choice: Disabled or Enabled.
DRAM Timing Selectable
The value in this field depends on performance parameters of the installed
memory chips(DRAM). It is recommended that you don't change the value
from the factory setting unless you install new memory that has a different
performance rating than the original DRAMs.
Ø The Choice: Manual or BySPD
CAS Latency Time
When synchronous DRAM is installed, the number of CAS latency clock
cycles depends on the DRAM timing. It is recommended don't change
this field from the default value specified.
Ø
The Choice: Auto, 3, 4, 5 or 6.
DRAM RAS # to CAS # Delay
This field lets you insert a timing delay between the CAS and RAS strobe
signals when DRAM is written to, read from, or refreshed. Faster perfor-
mance is gained at high speed, more stable performance, at low speed.
This field is applied only when synchronous DRAM
is installed in the system.
Ø The Choice: Auto, 2, 3, 4, 5 or 6.
