DDR PPR Type
Post Package Repair (PPR) is a new feature available for the DDR4/DDR5 technology.
PPR provides additional spare capacity within a DDR4/DDR5 DRAM module that is
used to replace faulty cell areas detected during system boot. PPR offers two types of
memory repairs. Soft Post Package Repair (sPPR) provides a quick, temporary fix on a
raw element in a bank group of a DDR4/DDR5 DRAM device, while hard Post Package
Repair (hPPR) will take a longer time to provide a permanent repair on a raw element.
The options are PPR Disabled, Hard PPR, and Soft PPR.
Enhanced PPR
Use this feature to set advanced memory test for PPR enhancement. Select Persistent to
always execute PPR for every boot. The options are Disabled, Enabled, and Persistent.
Memory PFA Support (Available when the DCMS key is activated)
Select Enabled to enable memory Predictive Failure Analysis (PFA) support. PFA can be
used to avoid uncorrectable faults in the same memory page. The options are Disabled
and Enabled.
PMem Configuration (Available when any Pmem device is detected by
the BIOS)
Note: This submenu depends on the support of Intel Optane Pmem 300 Series.
PMem QoS
Use this feature to set the PMem Quality of Service (QoS) mode. The options are Dis-
abled and Profile 1.
PMem Performance Setting
This feature configures the baseline (default) performance setting for the onboard PMem
memory, which largely depends on workload requirements. Select BW (Bandwidth) Op-
timized to optimize PMem performance. The options are BW Optimized and Balanced
Profile.
Seamless: Opt-in DIMMs
This feature allows you to update PMem firmware if the DIMM firmware is available. The
options are Keep, Disabled, and Enabled.
