This 64GB RAM is 100% compatible with the Dell Precision 7820 Tower.

Information on memory configuration: The following technical specifications should be considered in advance: The device can support RDIMM and RDIMM 3DS (Registered DIMM) or LRDIMM and LRDIMM 3DS (Load Reduced DIMM) RAM. LRDIMM memory is recommended for achieving large memory capacities. RDIMM and RDIMM 3DS memory modules cannot be mixed with LRDIMM and LRDIMM 3DS memory. If a memory expansion 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: Xeon CPUs of the 2nd generation 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 1.331 TB
Silver 4200 2.400 1 TB
Gold 5200 2.666 1 TB, 2 TB, 4.5 TB
Gold 6200 2.666 1 TB, 2 TB, 4.5 TB
Platinum 8200 2.933 1 TB, 2 TB, 4.5 TB
Platinum 9200 2.933 1.5 TB.
