Clear CMOS (J1800/1801)
If the board no longer boots up or the BIOS setup can no longer be called, then you can reset the settings
stored in the CMOS with the "Clear CMOS" jumpers. To do this you must switch the computer off and first
remove jumper 1 and then jumper 2 from their normal positions (contacts 1 and 2 closed) and plug them into
the position "contacts 2 and 3 closed". After a few seconds, place the jumpers back in their normal positions
again. Subsequently, the board boots up with the default settings as delivered ex factory.

NOTE
Jumper settings
Prevent the system from entering an undefined state and make sure that the short-circuiting of the
Clear
CMOS 1 jumper (J1800)
takes place
BEFORE
and
only together
with the setting of the
Clear CMOS 2
jumper (J1801)
.
Please also remember that resetting the CMOS will delete all settings made in the BIOS setup and thus
also the time and date saved there, therefore the clock has to be set again afterwards.

Memory SO-DIMM260 (U600/700 and U601/701)
On the CB1067 board there are four SO-DIMM260 memory slots for DDR4-2666 RAM. For technical and
mechanical reasons, it is possible that certain memory modules cannot be used. Information regarding the
recommended memory modules can be obtained from your distributor.
With four slots, a memory extension up to 128 GB is possible with currently available modules.
All timing parameters for the different makes and versions are automatically set by the BIOS.
