2.3.4. System Memory
The COMe-bV26 supports up to 64 GByte of SODIMM memory with dual DDR4-3200.
System Memory Description
Socket 2x DDR4 SODIMM
Type DDR4-3200 ECC
Size (Max.) 64 GByte (2x32 GByte)
Technology Dual channel
Memory Speed 3200 MTs (max.)
ECC
[1]
In-band ECC
[1]
In band ECC improves safety and reliability by providing ECC protection to specific regions of the physical memory.
Out of band ECC is not supported.
The two SODIMM memory sockets are located on the top side of the module where socket one is 4 mm height and
socket two is 8 mm high. Each socket may be populated with a DDR4 DIMM module mounted horizontally.
In general, memory modules have a much lower longevity than embedded motherboards, and therefore the EOL of
the memory modules may occur several times during the lifetime of the motherboard. Kontron guarantees to
maintain memory modules by replacing EOL memory modules with another qualified similar module.
As a minimum, it is recommended to use Kontron memory modules for prototype system(s) in order to prove the
stability of the system and as a reference.
For volume production, if required, test and qualify other types of RAM. In order to qualify RAM it is recommend to
configure three systems running a RAM Stress Test program in a heat chamber at 60°C, for a minimum of 24 hours.
For a list of Kontron memory modules, see Table 3: Accessories
2.3.5. Graphics
The COMe-bV26 supports up to four simultaneous displays on the Digital Display Interface (DDIO) using the
processor’s graphics controller with VEGA 6 and VEGA7 graphics core architecture supporting up to seven GPU core
counts, depending on the processor. LVDS is supported as an option using an eDP to LVDS bridge chip and VGA is
supported as an option using a Display Port (DP) to VGA bridge chip.
The following table list the display features.
