Sub-Section Description/Notes
For details on the supported memory configurations on the HP Z820 Workstation, please
refer to the System Technical Specifications - System Board section of this document.
DIMMs should be distributed across all four memory channels for optimal performance.
Each processor supports up to 4 channels of DDR3 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 a 1066MHz capable CPU
is used in the system, the maximum speed the memory will run at is 1066MHz regardless of
the specified speed of the memory.
NOTE:
You cannot intermix registered and unbuffered DIMMs. The system will not work.
NOTE:
You cannot intermix LR DIMMs with either registered or unbuffered DIMMs. The
system will not work.
