PHS-memory 16GB RAM Memory for HP Z820 DDR3 RDIMM 1333MHz

This 16GB RAM is 100% compatible with the HP Z820.

Information on memory configuration: The following technical specifications should be considered in advance: RDIMM (Registered DIMM) or LRDIMM (Load Reduced DIMM) RAM can be installed in the device. LRDIMM memory is recommended when large memory capacities are needed. RDIMM memory modules cannot be mixed with LRDIMM memory. If a memory upgrade is to be made with the existing RAM, it must be checked which memory technology (RDIMM / LRDIMM) is currently in use. Memory slots without a processor present must not be populated. A higher memory clock speed of the memory module will automatically adjust to the memory clock speed set by the system. This can especially be the case with larger capacities. Low Voltage memory with 1.35V will be clocked at 1.5V when mixed with 1.5V memory due to the fallback option available in the memory. There are 4 memory channels per CPU, each with 3 memory slots.
