Sufficient cooling must be applied to the APU in order to remove the effect defined as TDP (Thermal Design Power).
The sufficient cooling is also depending on the worst case maximum ambient operating temperature and the actual
worst case load of processor.
3.5. System Memory Support
The mITX-VR1000 has two DDR4 SO-DIMM sockets. The sockets support the following memory features:
2x DDR4 SO-DIMM, 1.2 V
Up to 32 GB (2x 16 GB)
Dual channel, 260-pin, 3200 MT/s (V1807B and V1756B) or 2400 MT/s (V1605B and V1202B)
SPD timing supported
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.

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.
