Description
This option enables one of the Mid-Level Cache (MLC) AMP
hardware Prefetcher. This option is set to Disabled by default.
This option allows L1 Data Cache Unit (DCU) to prefetech, when
the Fill Buffers (FB) is full. Auto maps to hardware default
setting. This option is set to Auto by default.
This setting controls whether the Running Average Power Limit
(RAPL) balancer is enabled or not. If enabled, it activates the
uncore power budgeting. This option is set to Enabled by
default.
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
Enabled by default.
This field controls Intel CPU Crash Log feature for collection
of previous crash data from shared SRAM of Out-of -Band
Management Service Module at post reset. 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 processor microcode version.
