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. Select Enable to always execute for
every boot. Select Once to execute only one time. The options are Disabled, Enabled,
and Once.
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.
