32GB DDR5 ECC RDIMM for ProLiant Gen11

This 32GB DDR5 4800 CL40 2Rx8 registered ECC module is built for HP ProLiant DL325 Gen11, DL345 Gen11, DL360 Gen11, DL365 Gen11 and DL380 Gen11 servers. It replaces HP part numbers P43328-B21, P46968-H21, P50311-B21, P58356-H21 and P62603-B21. It will not work in standard desktop computers and cannot be mixed with unbuffered or load-reduced ECC memory.

Thermals noise and power at 1.1V

Operating at 1.1 volts, the module draws minimal power and generates little heat without a heat spreader. Registered buffering reduces electrical load on the memory controller, keeping system fan speeds low during typical server workloads.

Sustained load behaviour with ECC registered design

Error-correcting code detects and corrects single-bit errors in real time, preventing data corruption during continuous operation. The registered architecture maintains signal integrity across all 288 pins when every slot is populated, so throughput remains stable over extended compute runs.

Questions about this item

How do I install the 288-pin DDR5 4800 RDIMM in an HP ProLiant DL360 Gen11, and what step is often missed?

Power down the server, open the chassis, align the module key with the slot notch, press firmly until both ejector clips lock, then verify in BIOS that the 32GB 2Rx8 module is detected at 4800 MT/s with ECC active.

What maintenance or replacement will the 32GB DDR5 ECC registered module need over its service life?

No scheduled maintenance is required; the module has no heat spreader or moving parts, so replacement only occurs if a memory error is logged or a capacity upgrade is planned.

What limit appears first when the 1.1V DDR5 4800 RDIMM runs sustained workloads in a DL380 Gen11?

The registered buffer and CL40 latency set the throughput ceiling; thermals stay within JEDEC limits at 1.1V, so bandwidth saturation arrives before temperature throttling.
