Server DDR4 2400 ECC RDIMM

This 8 GB registered module runs at DDR4 2400 with CL17 latency and 1.20 V operation. It is built for HP ProLiant and compatible server platforms that require ECC error correction and registered signal buffering. The single-rank 1Rx8 organisation suits configurations that populate many DIMM slots per channel. Administrators expanding memory in supported systems will find a direct drop-in part.

Sustained load behaviour

ECC circuitry detects and corrects single-bit errors during continuous operation, preventing silent data corruption in long-running workloads. Registered signalling reduces electrical load on the memory controller, keeping timing margins stable when all 288-pin slots are populated. The module maintains its rated 2400 MT/s throughput under extended duty cycles typical of virtualization hosts and database servers.

Upgrade scope and limits

This part replaces any of the listed HP part numbers such as 805347-B21, 809080-591, 819410-001, 851353-B21, 853287-091 or 854592-B21. The jump is worthwhile when the platform supports DDR4 2400 registered ECC and the current configuration has free DIMM slots or lower-capacity modules. It does not suit systems that require unbuffered UDIMMs, higher speeds or capacities beyond 8 GB per slot.

Questions about this item

How much power does this 1.20V DDR4 2400 ECC RDIMM draw when running continuously in a server?

The module operates at the standard DDR4 voltage of 1.20V, which is the baseline for DDR4 power consumption; actual draw depends on the platform's memory controller and workload.

What must the system provide to use this 288-pin registered ECC DDR4 module?

A server or workstation motherboard with DDR4 RDIMM slots, registered ECC support in the chipset or CPU, and a memory controller qualified for DDR4 2400 operation.

Can this CL17 1Rx8 registered ECC DDR4 module be mixed with other DDR4 RDIMMs of different speeds or ranks in the same server?

Mixing is possible only if the platform supports mixed-rank and mixed-speed populations; the system will run all modules at the lowest common speed and may require specific slot placement per the vendor's memory population rules.
