 ECC supported
The installed DDR4 SO-DIMM should support the Serial Presence Detect (SPD) data structure. This allows the BIOS to
read and configure the memory controller for optimal performance. If non-SPD memory is used, the BIOS will attempt
to configure the memory settings, but performance and reliability may be impacted, or the board may not be able to
boot totally.

3.5.1. Memory Operating Frequencies

In all modes, the frequency of system memory is the lowest frequency of all the memory modules placed in the
system. Each memory module's frequency can be determined through the SPD registers on the memory modules.
The table below lists the resulting operating memory frequencies based on the combination of SO-DIMMs and
processor.

SO-DIMM Type Module Name
DDR4 1866 PC4-1866
DDR4 2133 PC4-2133
Memory modules have in general a much lower longevity than embedded motherboards, and therefore EOL of
modules can be expected several times during lifetime of the motherboard.
As a minimum it is recommend using Kontron memory modules for prototype system(s) in order to prove stability of
the system and as for reference.
For volume production you might request to test and qualify other types of RAM. In order to qualify RAM it is
recommend configuring 3 systems running RAM Stress Test program in heat chamber at 60° C for a minimum of 24
hours.

3.6. On-board Graphics Subsystem

The mITX-SSH-S supports Intel® HD Graphics technology for high quality graphics capabilities. All mITX-SSH-S
versions support three displays pipes.
Up to three displays can be used simultaneously and be used to implement independent or cloned display
configuration.
