This 16GB RAM is 100% compatible with the Supermicro X11DPFF-SN.

Information on memory configuration: The following technical specifications should be considered in advance: The device can install RDIMM and RDIMM 3DS (Registered DIMM) or LRDIMM and LRDIMM 3DS (Load Reduced DIMM) RAM. LRDIMM memory is recommended when large memory capacities are required. RDIMM and RDIMM 3DS memory modules cannot be mixed with LRDIMM and LRDIMM 3DS memory. If a memory upgrade is to be performed with the existing RAM, it must be checked which base memory technology (RDIMM / LRDIMM) is present. When using a multiprocessor system, the memory slots should always be populated identically for each CPU. Memory slots without a processor must not be populated. If memory modules with higher clock rates than specified by the system are offered, the memory clock will automatically adjust to the system specifications. The CPU supports 6 DIMMs per memory channel. Maximum memory speed of possible CPUs: 1st generation Xeon CPUs are offered as Bronze, Silver, Gold, or Platinum. The different processor series support different maximum clock frequencies: Xeon CPU series max. Speed MHz Bronze 3100 2133 Silver 4100 2400 Gold 5100 2666 Gold 6100 2666 Platinum 8100 2666.
