3.5. Processor Support
The 3.5"-SBC-WLU is designed to support 8th Generation Intel® Core™ / Celeron® U-Series Processors. The BGA CPU
is remounted from factory. Kontron has defined the board versions as listed in the following table, so far all based on
Embedded CPUs. Other versions are expected at a later date.

Sufficient cooling must be applied to the CPU in order to remove the effect as listed as TDP (Thermal Design Power) in
above table. The sufficient cooling is also depending on the worst case maximum ambient operating temperature and
the actual worst case load of processor.
3.6. System Memory Support
The 3.5"-SBC-WLU has two DDR4 SO-DIMM sockets. The sockets support the following memory features:
 2x DDR4 SO-DIMM 260-pin
 Dual-channel with 1x SO-DIMM per channel
 Up to 64 GB
 SPD timing supported
 ECC not 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.
3.6.1. 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.
