National Instruments PXIe-8862 User Manual

■
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. This setting will be
grayed out if system profile is OS defined.
■
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.
■
Turbo Boost—This setting enables or disables Intel Turbo Boost technology.
The default 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 be careful
when enabling this setting on a LabVIEW Real-Time system. To achieve
maximum possible Turbo Boost frequencies, also enable the C-States setting.
■
Adjacent Cache Line Prefetcher—This setting enables or disables the
processor mechanism to fetch the adjacent cache line within a 128-byte sector
that contains the data needed due to a cache line miss.
■
Hardware Prefetcher—This setting enables or disables the processor
mechanism to prefetch data into the cache according to a pattern-recognition
algorithm.
■
VT-D—This setting enables or disables the Intel Virtualization technology for
directed I/O.
■
Kernel DMA Protection—This setting enables or disables the Kernel DMA
protection in Windows through an ACPI table.
■
Total Memory Encryption—This setting enables or disables the Total
Memory Encryption in the BIOS.
