Chapter 7: BIOS
Frequency Ratio
(Available when supported by the CPU.)
The feature allows the user to set the internal frequency multiplier for the CPU.
The default setting is Default.
Frequency High Ratio
(Available when supported by the CPU.)
The feature allows the user to set high ratio internal frequency multiplier for Intel
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.)
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.
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 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 fl oating point (FP) state. 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 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 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 options
are Disabled and Enabled.
