SNC
Sub NUMA Clustering (SNC) is a feature that breaks up the Last Level Cache (LLC) into
clusters based on address range. Each cluster is connected to a subset of the memory
controller. Enabling SNC improves average latency and reduces memory access congestion
to achieve higher performance. Select Auto for 1-cluster or 2-clusters depending on IMC
interleave. Select Enable for Full SNC (2-clusters and 1-way IMC interleave). The options
are
Disable
, Enable, and Auto.
Stale AtoS
This feature optimizes A to S directory. When all snoop responses found in directory A
are found to be RspI, then all data is moved to directory S and is returned in S-state. The
options are
Disable
, Enable, and Auto.
LLC dead line alloc
Select Enable to optimally fill dead lines in LLC. Select Disable to never fill dead lines in
LLC. The options are Disable,
Enable
, and Auto.
Memory Configuration
Enforce POR
Select POR to enforce POR restrictions for DDR4 memory frequency and voltage
programming. The options are
POR
and Disable.
Memory Frequency
Use this feature to set the maximum memory frequency for onboard memory modules. The
options are
Auto
, 1866, 2000, 2133, 2200, 2400, 2600, and 2666.
IMC Interleaving
This feature allows the user to configure Integrated Memory Controller (IMC) Interleaving
settings. The options are
Auto
, 1-way Interleave, and 2-way Interleave.
Data Scrambling for NVDIMM
Select Enable to enable data scrambling for onboard NVDIMM memory to enhance system
performance and security. The options are
Auto
, Disable, and Enable.
Data Scrambling for DDR4
Select Enable to enable data scrambling for DDR4 memory to enhance system performance
and security. The options are
Auto
, Disable, and Enable.
tCCD_L Relaxation
If this feature is set to Enable, SPD (Serial Presence Detect) will override tCCD_L ("Column
to Column Delay-Long", or “Command to Command Delay-Long” on the column side.) If
this feature is set to Disable, tCCD_L will be enforced based on the memory frequency.
The options are Disable and
Auto
