Chapter 6 BIOS Configuration
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; and Slow gives more stable performance. The
default setting is Slow.
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 data. Fast gives faster performance; and Slow
gives more stable performance. The default setting is Slow.
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.
CPU Warning Temperature
This field sets the threshold temperature at which an alert is sounded
through the system's speaker. The CPU temperature is monitored by the
onboard thermal sensor to prevent the CPU from overheating.
Current CPU/Chips Block Temp. / Current System Temp.
These read-only fields reflect the functions of the optional hardware
thermal sensor that monitors the chip blocks and system temperatures to
ensure the system runs stable.
Current Chassis / CPU Fan Speed
These optional and read-only fields show the current speeds in RPM
(revolution per minute) for the CPU fan and Chassis fan as monitored by
the optional hardware monitoring IC.
VCCP / VTT / VCC3
These optional and read-only fields show the current voltages in the
voltage regulators and power supply as monitored by the optional
hardware monitoring IC.
