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 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.
● Memory modules with ECC and without ECC may not be used in mixed operation.
● Memory modules with ECC can only be used in combination with the Xeon processor.
● 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.
