6.2 Expanding memory
Memory expansion options
The motherboard has 2 slots for memory modules. DIMM DDR3 1600 memory modules,
type PC3-12800, unbuffered, with or without ECC can be used. This allows you to expand
IPC memory capacity to up to 16 GB, of which you can use approx. 3.2 GB for the operating
system and applications with 32-bit operating systems. You can install one or two modules.
Combination Slot x19 (outside) Slot x20 (inside) Maximum expansion
1 2 GB/4 GB/8 GB 8 GB
2 2 GB/4 GB/8 GB 2 GB/4 GB/8 GB 16 GB
Note
Dual-channel operation and available memory
• The modules can be inserted into any slot. Memory is operated in dual-channel mode if
two modules are installed.
•
Memory modules with ECC and without ECC may not be used in mixed operation.
• If expansion modules with their own memory, for example graphics cards, with 256 MB or
more are used, the memory available for the 32-bit operating system or applications may
also be less than 3.2 GB.
In order to avoid operating faults you may have to remove a module so that the real
memory expansion on the motherboard and the reserved memory of the expansion
module do not overlap.
Preparation
Disconnect the device from mains and unplug all cables.
NOTICE
Electrostatic discharge
The electronic components on the PCBs are highly sensitive to electrostatic discharge.
Always take appropriate precautionary measures when handling these components. Refer
to the ESD directives on handling electrostatic sensitive components.
Note
We strongly recommend using only memory modules approved by Siemens. Siemens
disclaims any liability for impairment of functions caused by the use of third-party memory
modules.
