16GB DDR4 2666MHz ECC RDIMM Server Module

This 16GB DDR4 2666MHz ECC RDIMM module targets server and workstation administrators who need registered memory with error correction. The single 1Rx4 rank DIMM operates at 1.2V standard voltage with CL19 latency. It serves as a direct replacement for listed HP part numbers including P26030-001 and 881067-B21.

Registered ECC Design for Multi-DIMM Configurations

The registered buffer and ECC functionality allow stable operation when multiple modules populate a server motherboard. Error correction detects and corrects single-bit errors to maintain data integrity under sustained workloads. Major brand chipsets undergo quality assurance testing before shipment. No additional software or accessories are included with the memory module itself.

DDR4 288-Pin Interface Limits Speed and Density

The DDR4 288-pin interface caps transfer rates at 2666MHz PC4-21300 for this module. Registered DIMMs require motherboard slots wired for registered signalling; they will not function in unbuffered consumer boards. Single-rank 1Rx4 organisation limits maximum capacity per channel compared to dual-rank alternatives. Buyers needing higher frequencies or unbuffered operation must select a different memory type.

Questions about this item

Will the registered ECC RDIMM need any firmware updates or reconfiguration when I add it to a compatible HP server?

The module is a direct replacement for HP part numbers such as 815098-B21 and P26030-001, so it is recognised by the system BIOS without extra firmware steps.

What limits sustained throughput on this DDR4 2666 CL19 1Rx4 module?

The CL19 latency at 2666 MT/s sets the timing ceiling, while the single-rank x4 organisation caps maximum bandwidth per channel.

How much heat and power does the 1.2 V DDR4 RDIMM produce during continuous operation?

At the standard 1.20 V DDR4 voltage the module draws minimal power and generates low heat, aided by the registered buffer that reduces electrical load on the memory bus.
