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 be careful when enabling this setting on a Real Time system. When the BIOS is
configured to boot LabVIEW Real-Time, Hyper-Threading is disabled automatically. To
manually enable Hyper-Threading performance when in LabVIEW Real-Time mode,
refer to the
LabVIEW RT Configuration Overrides Submenu
.
•
Enabled CPU Cores
—This setting selects the number of active CPU cores for the
processor. Valid values are
1, 2, 3
and
All
. 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 also
can increase application jitter, so be careful when enabling this setting on a Real Time
system. To achieve maximum possible Turbo Boost frequencies, also enable the C-States
setting. When the BIOS is configured to boot LabVIEW Real-Time, Turbo Boost is
disabled automatically. To manually enable Turbo Boost performance when in LabVIEW
Real-Time mode, refer to the
LabVIEW RT Configuration Overrides Submenu
.
•
C-States
—This setting enables or disables CPU power management. The default value is
Enabled
. Enabling C-States allows the processor to put idle CPU cores to sleep, allowing
active cores to run at higher than base frequencies when Turbo Boost is enabled. Enabling
C-States can increase application jitter, so be careful when enabling this setting on a Real
Time system. When the BIOS is configured to boot LabVIEW Real-Time, C-States are
disabled automatically. To manually enable C-States when in LabVIEW Real-Time mode,
refer to the
LabVIEW RT Configuration Overrides Submenu
.
