uAdvanced 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, x6, x7, x8, x9, x10 and x11.
Frequency High Ratio (Available when supported by the CPU.)
The feature allows the user to set the high ratio internal frequency multiplier for the
Intel SpeedStep CPUs. The default setting is X12.
Note: If a wrong ratio that is not supported by the CPU is selected, the sys-
tem may hang. If this happens, clear the CMOS to recover the system.
Hyperthreading (Available when supported by the CPU.)
Set to Enabled to use the Hyperthreading Technology, which will result in increased
CPU performance. The options are Disabled and Enabled.
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.
Intel Enhanced Debug (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 activate the function of Machine Checking and 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.
L3 Cache (Available when supported by the CPU.)
Set to Enabled to enable the function of L3 Cache to optimize the system and CPU
performance. The options are Disabled and Enabled.
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
