Frequently Asked Questions
Which HP servers is this memory kit compatible with?
It is designed for HP ProLiant Gen8 servers that support PC3-12800E unbuffered ECC DIMMs, such as the ML310e, DL320e, and MicroServer Gen8 lines. Check your server's QuickSpecs for confirmed compatibility.
What is the difference between ECC unbuffered and ECC registered memory?
ECC unbuffered (UDIMM) memory is used in entry-level servers and workstations, while ECC registered (RDIMM) memory includes a register chip for stability in higher-capacity configurations. This kit is unbuffered and will not work in RDIMM-only slots.
Can I mix this 4GB module with other memory sizes in my server?
Mixing is possible in some configurations, but for optimal performance HP recommends using identical modules in matched pairs or sets. Consult your server's memory population guidelines.
What does HP SmartMemory mean?
HP SmartMemory is HP's authentication technology that verifies the DIMM is genuine HP-qualified memory. SmartMemory modules are tested to meet HP's standards and may unlock features like extended memory performance profiles on supported ProLiant servers.
