Technical white paper | HP Z440 Workstation
Memory configurations and
optimization
The purpose of this section is to provide an overview of the memory
configurations for the HP Z440 Workstation and to provide recommendations
to optimize performance.
Supported memory modules
Types of memory supported on an HP Z440 are:
• 4 GB, 8 GB and 16 GB PC4-2133R 2133 MHz DDR4 Registered DIMMs
• Single and dual rank 4 GB and 8 GB based DIMMs are supported
Types of memory NOT supported on an HP Z440 are:
• Unbuffered DIMMs
• Non-ECC DIMMs
• DDR, DDR2, or DDR3 DIMMs
• Load Reduced (LR) DIMMs
See Memory Technology White Paper for more memory module technical information.
Platform capabilities
Maximum capacity: 128 GB
HP Z440 has a total of 8 memory sockets
• 4 channels with 2 sockets per channel
Speed
• 2133 MHz, 1866 MHz and 1600 MHz memory speeds are supported in this platform.
• Memory will operate at the speed of the slowest rated installed processor or DIMM.
Dynamic power saving is enabled
Memory features
ECC is supported on all of our supported DIMMs
• Single-bit errors are automatically corrected.
• Multi-bit errors are detected and will cause the system to immediately reboot and halt with an F1 prompt error
message.
• Non-ECC memory does not detect or correct single-bit or multi-bit errors which can cause instability, or corruption of
data, in the platform. See Memory Technology White Paper for more information.
Command and Address parity is supported
