6.3  Memory expansion 
The motherboard is equipped with four slots for memory modules. Use the modules to 
expand the memory capacity of your device to a maximum of 32 GB. You can use 
approximately 3.2 GB of this memory in a 32-bit operating system and much more in a 64-bit 
operating system. 
A detailed description of possible memory expansion options is available in the "Technical 
manual of the motherboard" on the "Documentation and Drivers" DVD that ships with the 
product.

PCIe specification 1.0a (32-bit; 33 MHz, Rev. 2.3). The dimensions of the cards may not 
exceed the specified dimensions. If the height is exceeded, you may experience contact 
problems, malfunctions and difficulties with the assembly. 
The permitted module dimensions are specified in the section Dimensional drawings for

not permitted to exceed 25W in total. 
●  Long PCI, PCIe modules 
To insert long modules into the guide rails, they must be equipped with an extender. The 
extender should be included in the product package for long modules.
