Description
When option is set to Enabled, the system performs the force full
memory training steps on every power on and boot time is slowed on
every boot.
This option controls DIMMs slots on the system. This option is set to
Enabled by default. It allows to disable system installed DIMMs.
Enables or disables correctable error logging. This option is set to
Disabled by default.
Enables or disables Post Packing Repair (PPR) on uncorrectable memory
error. This option is set to Enabled by default.
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.
Limit CPU physical address to 46 bits to support older Hyper-
v. If enabled, automatically disables TME-MT. This option is
set to Enabled by default.
When set to Enabled, the BIOS will enable processor
Virtualization features and provide the
virtualization support to the Operating System (OS) through
Pre-operating system management applications
