Description

Management option is disabled. This option is set to Auto by

default.

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.

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.

Specifies the maximum core frequency of the processor.

Specifies the bus speed of the processor.

NOTE:

The processor bus speed option displays only

when both processors are installed.

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.

NOTE:

Depending on the number of processors, there

might be up to n processors listed.

The following settings are displayed for each processor:

Description

Specifies the family, model, and stepping of the processor as

defined by Intel.

Specifies the brand name.

Specifies the total L2 cache.

Specifies the total L3 cache.

Specifies the number of cores per processor.

Specifies the maximum memory capacity per processor.

Specifies the processor microcode version.
