8GB DDR4 2933 ECC RDIMM

This 8GB DDR4 2933 ECC RDIMM is built for servers and workstations that require registered memory with error correction. It replaces specific HP part numbers including P19040-K21, P03049-091, P00918-B21, P12400-B21, P03049-191, P13208-001, P03048-091, P19040-B21, P19040-H21, and 5YZ56AT. The module uses major brand chips and operates at standard 1.20V DDR4 voltage.

Capacity and headroom

The single 8GB 1Rx8 module handles typical virtualization hosts, database nodes, and compute workloads that fit within this capacity per slot. Registered buffering and ECC protect data integrity under sustained load, but the 8GB limit per DIMM restricts total memory density in systems with fewer slots. Workloads needing larger per-module capacity will require higher-density registered DIMMs.

CL21 at 2933 MHz

CAS latency 21 at DDR4 2933 (PC4-23400) defines the timing profile the memory controller must support. Systems qualified for this speed and latency will run at the rated specification; platforms limited to lower speeds will downclock the module accordingly. Verify the platform memory QVL for 2933 MHz CL21 registered DIMM support before purchase.

Questions about this item

Will this DDR4 2933 registered ECC module run alongside my existing DDR4 RDIMMs?

The module runs at DDR4 2933 CL21 1.20 V as a 1Rx8 registered ECC DIMM. Most servers will clock all installed memory to the slowest module’s speed and timings.

How can I confirm the 8 GB DDR4 2933 stick is detected correctly after installation?

Check the BIOS or UEFI memory information screen; it should show the new module as 8 GB, DDR4 2933, ECC registered, 1Rx8 organisation.

Does the box contain only the 288-pin DIMM or are extra parts included?

The package includes the single 8 GB DDR4 2933 ECC RDIMM. No brackets, cables or additional components are supplied.
