X7DWE User's Manual
CPU fetches both cache lines for 128 bytes as comprised if Enabled. The options
are Disabled and Enabled.
Hardware Prefetch (Available when supported by the CPU.)
Set 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.
Set Maximum Ext. CPUID=3
When set to Enabled, the Maximum Extended CPUID will be set to 3. 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).
Intel <R> Virtualization Technology (Available when supported by the CPU.)
Select Enabled to use the feature of Virtualization Technology to allow one platform
to run multiple operating systems and applications in independent partitions, creat-
ing multiple "virtual" systems in one physical computer. The options are Enabled
and Disabled. Note: If there is any change to this setting, you will need to power off
and restart the system for the change to take effect. Please refer to Intel's website
for detailed information.
Intel EIST 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 website for detailed information.
C1 State Mode (Available when supported by the CPU.)
Select Disable to disable the Standard C1 Halt State which will partially turn off
the CPU internal clocks to conserve energy and prevent system overheating when
the OS is idle. Select Enable to use the Enhanced C1 Halt State to lower the CPU
clock frequency and the supply voltage before turning off the clocks.
