This 16GB RAM is 100% compatible with Cisco UCS C890 M5.

Information on memory configuration: The following technical specifications should be considered in advance: The device can be equipped with 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 made 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 should 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 the possible CPUs: 2nd 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, max. memory capacity per CPU
• Bronze: 3200 MHz, 1331 TB
• Silver: 4200 MHz, 4001 TB
• Gold: 5200 MHz, 2661 TB, 2 TB, 4.5 TB
• Gold 6200: 2661 TB, 2 TB, 4.5 TB
• Platinum 8200: 2933 TB, 1 TB, 2 TB, 4.5 TB
• Platinum 9200: 2933 TB, 1.5 TB.
