Option Description
mapped out. When set to En
abled it can impact the system performance
under certain workloads. This feature is applicable for x4 DIMMs only. This
option is set to Enabled by default.
Memory training When option is set to Fast and memory configuration is not changed,
the system uses previously saved memory training parameters to train
the memory subsystems and system boot time is also reduced. If memory
configuration is changed, the system automatically enables Retrain at
Next boot to force one-time full memory training steps, and then go back
to Fast afterward.
When option is set to Retrain at Next boot, the system performs the
force one-time full memory training steps at next power on and boot time
is slowed on next boot.
When option is set to Enable, the system performs the force full
memory training steps on every power on and boot time is slowed on
every boot.
DIMM Self Healing (Post Package Repair) on
Uncorrectable Memory Error
Enables or disables Post Packing Repair (PPR) on uncorrectable memory
error. This option is set to Enabled by default.
Correctable Error Logging Enables or disables correctable error logging. This option is set to
Disabled by default.
Memory Map Out This option controls DIMMs slots on the system. This option is set to
Enabled by default. It allows to disable system installed DIMMs.
Processor Settings
To view the Processor Settings screen, power on the system, press F2, and click System Setup Main Menu > System
BIOS > Processor Settings.
Table 44. Processor Settings details
Option Description
Logical Processor Each processor core supports up to two logical processors. If
t
h
is 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.
CPU Interconnect Speed 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
l
ink frequencies.
The options available are M
a
ximum data rate, 16 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.
