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.
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.)
Execute Disable Bit
(
*
Available when supported by the CPU and the OS.)
Set to Enabled to enable Execute Disable Bit and allow the processor to classify
areas in memory where an application code can execute and where it cannot, and
thus preventing a worm or a virus from inserting and creating a fl ood of codes to
overwhelm the processor or damage the system during an attack.
(*Note: this feature is available when your OS and your CPU support the function
of Execute Disable Bit.) The options are
Disabled
and Enabled. (Note: For more
information regarding hardware/software support for this function, please refer to
Intel's and Microsoft's web sites.)
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.
Hardware Prefetcher
(
*
Available when supported by the CPU.)
Set to this option to
enabled
to enable the hardware components that are used in
conjunction with software programs to prefetch data in order to shorten execution
cycles and maximize data processing effi ciency. The options are Disabled and
Enabled
.
Direct Cache Access
(
*
Available when supported by the CPU.)
Set to Enable to route inbound network IO traffi c directly into processor caches
to reduce memory latency and improve network performance. The options are
Disabled
and Enabled.
DCA Delay Clocks
(
*
Available when supported by the CPU.)
This feature allows the user to set the clock delay setting from snoop to prefetch
for Direct Cache Access. Select a setting from 8 (bus cycles) to 120 (bus cycles)
(in 8-cycle increment). The default setting is
32 (bus cycles)
.
