For details on the supported memory configurations on the HP Z640 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.
With single-processor configurations, 4 DIMM slots are available. 4 additional DIMM slots are available
with the 2nd CPU & Memory Module.
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.
ONLY registered and load reduced DDR4 DIMMs are supported.
