OWC 64GB DDR4 2933 ECC RDIMM

This OWC module is a single 64GB DDR4 2933 PC4-23400 CL21 2Rx4 288-pin 1.2V ECC Registered DIMM. It is designed for workstation and server environments that require registered ECC memory. The part number is 2R9D42R464GB. It replaces multiple HP part numbers including P19045-K21 and P00930-B21.

Verify HP Cloudline Gen10 compatibility

Confirm your system is an HP Cloudline CL2600 Gen10, CL3100 Gen10, CL4100 Gen10 or CL5800 Gen10 before ordering. This registered ECC RDIMM will not work in standard desktop computers. It also cannot be mixed with unbuffered or load-reduced ECC memory modules already installed.

Suits HP Cloudline Gen10 server upgrades.

This upgrade suits administrators extending the life of compatible HP Cloudline Gen10 servers or building new configurations with validated memory. Buyers needing memory for standard desktop PCs, laptops or consumer motherboards should look elsewhere because registered ECC RDIMMs are physically and electrically incompatible with those platforms.

Questions about this item

Does the OWC 64GB DDR4 2933 module ship as a single DIMM or a kit, and is any extra hardware required?

The upgrade consists of one 64GB 288-pin ECC Registered DIMM; no additional hardware is needed for installation.

Should I choose the 2933MHz CL21 2Rx4 version or a different speed and rank for my HP Cloudline Gen10 server?

This 2933MHz CL21 2Rx4 module matches the HP part numbers listed for the CL2600, CL3100, CL4100 and CL5800 Gen10 and is the correct specification for those systems.

What does the 2933MHz PC4-23400 rating mean when the module runs in a CL2600 Gen10 server?

The module will operate at up to 2933MHz with CL21 latency at 1.2V, and it is backward compatible with 2133MHz, 2400MHz and 2666MHz bus speeds if the platform requires a lower frequency.
