HP Z230 Memory Configurations and Optimization

Platform capabilities
Maximum capacity: 32 GB
HP Z230 has a total of 4 memory sockets
2 channels with 2 sockets per channel
Speed
1600 MHz and 1333 MHz DIMMs
1, 2
are supported
Memory will operate at the speed of the slowest rated installed processor or DIMM.
Memory features
ECC is supported on Unbuered ECC 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.
Although HP does support non-ECC memory on this platform as a lower cost option, it should be noted that 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.
Optimizing performance
Generally, maximum memory performance is achieved by evenly distributing total desired memory capacity across all
operational channels. Proper individual DIMM capacity selection is essential to maximizing performance. Refer to the Optimal
Memory Conguration tables below for more information.
Optimal memory congurations
(Note: The following tables do not include all available factory installed congurations).
Table 2. Processor and memory support
* Maximum memory capacities assume Windows 64-bit operating systems or Linux. With Windows 32-bit operating systems, memory
above 3 GB may not all be available due to system resource requirements.
~ Although supported, these congurations are not factory congurable at this time.
