Description
This option controls DIMMs slots on the system. This option is set to
Enabled by default. It allows to disable system installed DIMMs.
Description
Each processor core supports up to two logical processors.
If this option is set to Enabled, the BIOS displays all the
logical processors. If this option is set to Disabled, the BIOS
displays only one logical processor per core. This option is set
to Enabled by default.
Enables you to govern the frequency of the communication
links among the processors in the system.
NOTE:
The standard and basic bin processors support
lower link frequencies.
The options available are Maximum data rate, 16.0 GT/s,
14.4 GT/s, and 12.8 GT/s. This option is set to
Maximum data rate by default.
Maximum data rate indicates that the BIOS runs the
communication links at the maximum frequency
supported by the processors. You can also select specific
frequencies that the processors support, which can vary.
For best performance, you should select Maximum data
rate. Any reduction in the communication link frequency
affects the performance of non-local memory access
and cache coherency traffic. In addition, it can slow access to
non-local I/O devices from a particular processor.
However, if power saving considerations outweigh
performance, reduce the frequency of the processor
communication links. Before reducing the frequency, you must
localize the memory and I/O access to the nearest
NUMA node to minimize the impact to system performance.
Enables or disables the virtualization technology for the
processor. This option is set to Enabled by default.
This option is set to Disabled by default. It is enabled for
Secure Launch (Firmware Protection) support on Windows
2022.
This option is set to Enabled by default. ATS provides
an interface between Chipset's address translation and
protection table to translate DMA addresses to host
addresses.
Enables or disables the directory mode. This option is set to
Enabled by default.
Optimizes the system for applications that need high
utilization of sequential memory access. This option is set
to Enabled by default. You can disable this option for
Pre-operating system management applications
