Motherboard User's Guide
DRAM CAS# Latency
This item determines the operation of SDRAM memory CAS (column address
strobe). It is recommended that you leave this item at the default value. The 2T
setting requires faster memory that specifically supports this mode.
DRAM Bank Interleave
Enable this item to increase DRAM memory speed. When enabled, separate
memory banks are set for odd and even addresses and the next byte of memory
can be accessed while the current byte is being refreshed.
Hyper Threading Function
You can set "Disabled" or "Enabled" to control HT CPU support in O.S. Set
"Enabled" to test HT CPU function.
Auto detect DIMM/PCI Clock
When this item is enabled, BIOS will disable the clock signal of free DIMM/PCI
slots.
Spread Spectrum
If you enable spread spectrum, it can significantly reduce the EMI (Electro-
Magnetic Interference) generated by the system.
Max CPUID Value Limit
When this item is enabled, you can use Prescott CPU and LGA-775 CPU and
there will be a normal NT4.0 installation; otherwise, the automatically restarting
will occur while installing.
Execute Disable Bit
It allows the processor to classify areas in memory by where application code
can execute and where it cannot. When a malicious worm attempts to insert code
in the buffer, the processor disables code execution, preventing damage or worm
propagation. Replacing older computers with Execute Disable Bit-enabled
systems can halt worm attacks, reducing the need for virus related repairs.
CPU TM Function
For some specific brands of CPU, you can use this item to control the CPU
frequency and voltage according to its temperature.
C1E Support
Use this item to decrease the bus ratio that reduces the consumption of CPU
electricity and power.
Intel (R) SpeedStep (tm) tech.
Use this item to enable or disable the Intel SpeedStep Technology, which is only
for the Intel CPU supporting the SpeedStep Technology function.
Venderpool Technology
Use this item to enable or disable the Venderpool Technology, which is only for
the CPU supporting the VT function.
