Usable memory modules

Combination options for memory modules
You can equip each device with 1, 2 or 4 memory modules of the same capacity. Combining
three memory modules or mixing memory capacities is not permitted.
This allows you to expand IPC memory capacity to up to 64 GB, of which you can use
approx. 3.2 GB for operating systems and applications with 32-bit operating systems.
Depending on the number of memory modules used, these are inserted in defined slots on
the motherboard.
The slots are inscribed on the motherboard.

Usable memory modules
● DIMM DDR4 memory modules
● Memory transaction rate 2666 MT/sec "unbuffered"
● "without ECC"
Conditions of use of memory modules
● Memory is operated in dual-channel mode if two modules are installed.
● Only modules of the same module organization 2Rx8 or 1Rx8 may be used per channel.
● If expansion cards with their own memory, such as graphics cards, with 256 MB or more
are used, the memory that can be used for the operating system or applications may be
less than 64 GB.
● In faults occur, it may be enough to remove one or two memory modules or use a
memory module with less capacity so that the physical memory set up on the
motherboard and the reserved memory on the expansion card do not overlap.
