A-Tech 8GB DDR4 2400 ECC RDIMM 1Rx8 Server Memory for HP 805347 809080 819410 851353 853287 854592

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.
