NOTES:
For details on the supported memory configurations on the HP Z8 G4 Workstation, please refer to the System
Technical Specifications - System Board section of this document.
Sleep (S3 state) support:
- Sleep (S3 state) may not be supported with non-HP validated and qualified 64 GB LR DIMMs.
- Sleep (S3 state) not supported with 128 GB LR DIMMs
DIMMs should be equally distributed across all six memory channels for optimal performance.
Each processor supports up to 6 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 a 2400MT/s capable CPU is used in the
system, the maximum speed the memory will run at is 2400MT/s, regardless of the specified speed of the
memory.
MT/s = Million Transfers per second
You cannot intermix LR DIMMs with Registered DIMMs. The system will not work.
The Z8 G4 is designed to work ONLY with DDR4 memory. The system will not work with DDR3 memory.
