Memory options
The IBM System x3650 M4 supports DDR3 memory. The server supports up to 12 DIMMs when one
processor is installed and up to 24 DIMMs when two processors are installed. Each processor has four
memory channels, and there are three DIMMs per channel. The following rules apply when selecting the
memory configuration:
Server supports UDIMMs, RDIMMs, HyperCloud DIMMs (also known as HCDIMMs), and LRDIMMs.

Mixing different types of memory (UDIMMs, RDIMMs, HyperCloud DIMMs, and LRDIMMs) is not

supported.
Mixing 1.5 V and 1.35 V DIMMs in the same server is supported; in such a case, all DIMMs operate at

1.5 V.
