NOTE 2: All Tesla configurations require the HP Z4 Fan and Front Card Guide Kit, which is available both
CTO (G8T99AV) and AMO (J9P80AA).
NOTE 3: Supported on 700W PSU chassis only.
For details on the supported memory configurations on the HP Z440 Workstation, please refer to the
System Technical Specifications - System Board section of this document.
Each processor supports up to 4 channels of DDR4 memory. To realize full performance at least 1
DIMM must be inserted into each channel.
The CPUs determine the speed at which the memory is clocked. If an 1866MHz capable CPU is used in
the system, the maximum speed the memory will run at is 1866MHz, regardless of the specified speed
of the memory.
NOTE 1: ONLY registered DDR4 DIMMs are supported.
DDR3 DIMMs ARE NOT SUPPORTED.
NOTE 2: Configurations of greater than 4x memory DIMMs require the HP Z440 Memory Cooling
Solution, which is available both CTO (J2R51AV) and AMO (J2R52AA).
The HP Z440 Memory Cooling Solution is available to add to any configuration for improved system
cooling, but is required for proper memory cooling on any Z440 configuration with greater than 4
memory DIMMs installed. It can only be installed on the HP Z440 Workstation.
NOTE 3: If a user installs greater than 4 memory DIMMs in a Z440 system without also installing the HP
Z440 Memory Cooling Solution, they will be presented with an F1 boot stop requiring a manual
override each time the system is rebooted.
