7.3.1

Information on using memory modules

Usable memory modules
You can operate the device with the following memory modules:
• DIMM DDR5 memory modules
• Memory transaction rate 4800 MT/sec "unbuffered"
• "without ECC"
Slots for memory modules
Information on the slots of the memory modules can be found under "Layout of the
motherboard (Page 151)".
Combination options for memory modules
You can equip the device with one or two memory modules, each with the same memory
capacity. Mixing of memory capacities is not permitted.
You can use the modules to expand the memory capacity of your device to a maximum of
64 GB.
Depending on the number of memory modules used, these are plugged into defined slots on
the motherboard.
The slots are labeled on the motherboard.
Combination option
Combination 1
Combination 2
Conditions of use of memory modules
• When two identical memory modules are installed, memory is operated in dual-channel
mode.
• If expansion cards with their own storage, e.g. graphics cards, with 256 MB and more are
used, the memory available for an operating system or applications may be less than
64 GB.
• In case of operating errors, it may be sufficient to remove one or two memory modules or
to use a memory module with lower capacity so that the physical memory expansion on
the motherboard and the reserved memory of the expansion card do not overlap.
