SATA Configuration Submenu
Use this submenu to apply alternate settings to the hard disk drive (HDD)
interfaces. Normally, you do not need to modify these settings, as the
factory default settings provide the most compatible and optimal
configuration possible.
•
SATA Controller
—This setting specifies whether or not the onboard
SATA controller is enabled or disabled. The default value is
Enabled
.
–
SATA Mode Selection
—This setting determines whether AHCI
mode is enabled or disabled for the SATA port. Some operating
systems, such as Windows 2000, do not support AHCI mode. You
can use this setting to disable AHCI mode and enable IDE mode
so that non-compatible OSes function correctly. The default value
is
AHCI
.
•
Internal Drive (SATA)
—This item displays the onboard SATA drive
detected in the system.
CPU Configuration Submenu
Use this submenu to apply alternate settings to the CPU. Normally, you do
not need to modify these settings, as the factory default settings provide the
most compatible and optimal configuration possible.
•
Hyper-Threading
—This setting enables or disables Intel
Hyper-Threading technology. The default value is
Enabled
. Enabling
Hyper-Threading increases performance for some applications by
adding virtual CPU cores. Hyper-Threading can increase application
jitter, so care should be taken when enabling this setting on a
Real Time system. When the BIOS is configured to boot LabVIEW
Real-Time, Hyper-Threading will be automatically disabled. In order
to manually enable Hyper-Threading performance when in LabVIEW
Real-Time mode, see the
LabVIEW RT Configuration Overrides
Submenu
.
•
Enabled CPU Cores
—This setting selects the number of active CPU
cores for the processor. Valid values are
All
,
3
,
2
,
1
. The default value
is
All
.
•
Turbo Boost
—This setting enables or disables Intel Turbo Boost
technology. The default value is
Enabled
. Enabling Turbo Boost
allows CPU cores to run at higher than their base frequency for short
durations, while other cores are idle. Enabling Turbo Boost can also
increase application jitter, so care should be taken when enabling this
setting on a Real Time system. To achieve maximum possible Turbo
Boost frequencies, also enable the C-States setting.
