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.

On-board Graphics Subsystem
The ECX-BYT supports Intel® HD Graphics technology for high quality graphics capabilities. All ECX-BYT versions
support two displays pipes.
Up to two displays can be used simultaneously and be used to implement independent or cloned display
configuration.

Power Supply
In order to ensure safe operation of the board, the input power supply must monitor the supply voltage and shut
down if the supply is out of range – refer to the actual power supply specification. Please note, in order to keep the
power consumption to a minimal level, boards do not implement a guaranteed minimum load. In some cases, this can
lead to compatibility problems with ATX power supplies that require a minimum load to stay in regulation. The ECX-
BYT board must be powered through the ATX+12V-4p (4-pole) connector using standard ATX power supply.
ATX12V supply: ATX+12V-4p connector must be used in according to the ATX12V PSU standard.
Hot Plugging power supply is not supported. Hot plugging might damage the board.
The requirements to the supply voltages are as follows:
