Faster memory will clock down to run at optimal speed depending on processor model installed.
This system supports Registered RDIMM and Load Reduced LRDIMM memory modules. Modules of different memory types CANNOT be mixed within the same system.
If only one processor is installed, only 8 DIMM sockets can be populated. With two processors, all 16 DIMM sockets can be populated.
System storage could be configured many different ways. Please verify your system's configuration and contact Kingston Support.
