Advanced Processor Options
Access the submenu to make changes to the following settings:
CPU Speed
This is a display that indicates the speed of the installed processor.
Frequency Ratio (*Available when supported by the CPU.)
The feature allows the user to set the internal frequency multiplier for the CPU.
The options are: Default and x12.
Core-Multi-Processing (*Available when supported by the CPU.)
Set to Enabled to use a processor's Second Core and beyond. (Please refer to
Intel's web site for more information.) The options are Disabled and Enabled.
Machine Checking (*Available when supported by the CPU.)
Set to Enabled to use this function which will allow the CPU to detect and report
hardware (machine) errors via a set of model-specifi c registers (MSRs). The options
are Disabled and Enabled.
Enhanced Intel SpeedStep Support (*Available when supported by the
CPU.)
Select Enabled to use the Enhanced Intel SpeedStep Technology and allows the
system to automatically adjust processor voltage and core frequency in an effort
to reduce power consumption and heat dissipation. The options are Enabled and
Disabled. Please refer to Intel’s web site for detailed information.
Thermal Management 2 (*Available when supported by the CPU.)
Set to Enabled to use Thermal Management 2 (TM2) which will lower the CPU
voltage and frequency when the CPU temperature reaches a predefi ned overheat
threshold. Set to Disabled to use Thermal Manager 1 (TM1), allowing CPU clocking
to be regulated via CPU Internal Clock modulation when the CPU temperature
reaches the overheat threshold.
Adjacent Cache Line Prefetch (*Available when supported by the CPU.)
The CPU fetches the cache line for 64 bytes if this option is set to Disabled. The
CPU fetches both cache lines for 128 bytes as comprised if Enabled. The default
setting is Enabled.
Set Maximum Extended CPUID=3
Select Enabled to set the Maximum Extended CPUID value to 3. The options are
Enabled and Disabled.
Echo TPR
Select Enabled to send TPR (Transport Protocol) messages on the system bus.
The options are Enabled and Disabled.
