X7SBA User's Manual
SpeedStep CPUs. The default setting is x12.
Note: If a wrong ratio that is not supported by the CPU is selected, the system
may hang. If this happens, clear CMOS to recover the system.)
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 activate the function of Machine Checking and allow the CPU to
detect and report hardware (machine) errors via a set of model-specic registers
(MSRs). The options are Enabled and Disabled.
Compatible FPU Code (Available when supported by the CPU.)
Set to Enabled to keep the content of the last instruction Operating Code (OP
Code) in the oating point (FP) state. 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 CPU voltage
and frequency when the CPU temperature reaches a prede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 options
are Disabled and Enabled.
Set Maximum Ext. CPUID=3
When set to Enabled, the Maximum Extended CPUID will be set to 3. The options
are Disabled and Enabled.
Echo TPR
Set to Enabled to prevent xTPR messages from being sent to the system. The
options are Disabled and Enabled.
C1 Enhanced Mode (Available when supported by the CPU.)
Set to Enabled to enable Enhanced Halt State to lower CPU voltage/frequency to
prevent overheat. The options are Enabled and Disabled. Note: please refer to
Intel’s web site for detailed information.
