Table 5. Processor Settings details (continued)
Option Description
Management option is disabled. This option is set to Auto by
default.
CPU Physical Address Limit Enables or disables the CPU Physical Address Limit option.
When set to Enabled,it disables Multiple Keys Memory
Encryption and sets the physical memory address to 46 bits
to support older Hyper-v (MKTME). When set to Disabled,
the physical memory address is set to 52 bits to enable 5-
level paging, the system will crash at the driver verifier DMA
violation blue screen when booting with non-5-level paging-
supporting operating systems (Windows 2019 and, 2016 etc.)
This option is set to Enabled by default.
Number of Cores per Processor Controls the number of enabled cores in each processor. This
option is set to All by default.
NOTE: This setting restores to default when user changes
System Profile or CPU Power Management setting of
Profile Settings.
Processor Core Speed Specifies the maximum core frequency of the processor.
Processor Bus Speed Specifies the bus speed of the processor.
NOTE: The processor bus speed option displays only
when both processors are installed.
Local Machine Check Exception Enables or disables the local machine check exception. This
is an extension of the MCA Recovery mechanism providing
the capability to deliver Uncorrected Recoverable (UCR)
Software Recoverable Action Required (SRAR) errors to
one or more specific logical processors threads receiving
previously poisoned or corrupted data. When enabled, the
UCR SRAR Machine Check Exception is delivered only to the
affected thread rather than broadcast to all threads in the
system. The feature supports operating system recovery for
cases of multiple recoverable faults that are detected close,
which would otherwise result in a fatal machine check event.
The feature is available only on Advanced RAS processors.
This option is set to Disabled by default.
