Processor Support
The SDML-WLU0 Series is designed to support 8th Generation Intel® Core™ U-Series and Celeron® 4000 Series
Processors. The BGA CPU is remounted from factory. Kontron has defined the module versions as listed in the
following table. 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.

System Memory Support
The SDML-WLU0 Series 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 module 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.
