    • Fan can be set to maximum, if temperatures are high.

Memory expansion

Memory expansions must follow the predefined fill-order and memory-type requirements. There is a table documenting the memory fill order inside the server cabinet. Refer to that table when adding memory modules. Memory configurations with more than four memory DIMMs installed, require the HP Z440 Memory Cooling Solution (AMO kit P/N J2R52AA). This fan can be obtained from Vizrt, or directly from HP.
