Memory Operating Frequencies
Regardless of the SO-DIMM type used, the memory frequency will either be equal to or less than the processor
system bus frequency. For example, if DDR3L 1600 memory is used with a 1333 MHz system bus frequency processor,
the memory clock will operate at 167 MHz. The table below lists the resulting operating memory frequencies based on
the combination of SO-DIMMs and processor.

Kontron offers the following memory modules:
Part Number (PN) Memory Module Description Replaced Legacy PN
1060-2520 2 GByte DDR3L-1600, PC3-12800 1055-9939
1060-2522 4 GByte DDR3L-1600, PC3-12800 1055-9941
1060-2524 8 GByte DDR3L-1600, PC3-12800 1055-9942
Memory modules have, in general, a much lower longevity than embedded motherboards, and therefore EOL of
memory modules can be expected several times during the lifetime of the motherboard. Kontron guarantees that the
above Part Numbers (PNs) will be maintained by replacing EOL memory modules with other similar modules.
As a minimum, it is recommend to use Kontron memory modules for prototype system(s) in order to prove the
stability of the system and for reference.
For volume production you might want to test and qualify other types of RAM. In order to qualify RAM it is
recommend to configure 3 systems running a RAM Stress Test program in a heat chamber at 60
° C for a minimum of
24 hours.
3.5. mITX-BDW-U Graphics Subsystem
The mITX-BDW-U equipped with Intel ® i3, i5 or i7 processor, supports Intel ® Gen 8 HD Graphics core. All
mITX-BDW-U versions support three displays pipes. The DP interface supports the DisplayPort 1.2a specification. The
PCH supports high-bandwidth Digital Content Protection for high definition content playback over digital interfaces.
The PCH also integrates audio codecs for audio support over DP interfaces.
Up to three displays (DP1, DP2 & LVDS) can be used simultaneously and be used to implement independent or a
cloned display configuration. PCIe cards can be used to replace on-board graphics or in combination with on-board
graphics.
Intel® HD Graphics
Features of the Intel Gen 8 Graphics core built into the i3, i5 and i7 processors, includes:
 High quality graphics engine supporting
 3 Symmetric Pipe Support
 DirectX11.1 and OpenGL 4.x compliant and lower
 Full AVC/VC1/MPEG2 HW Decode
 Extension of H.264 format
 VP8* Decode HW Acceleration
 Advanced Scheduler 2.0, 1.0, XPDM support
 OpenGL* 4.0, OpenGL* 4.2 support
