Server-grade DDR4 ECC kit

This OWC kit supplies 256 GB of DDR4-2933 registered ECC memory in four 64 GB modules. It is built for HP ProLiant DL560 Gen10, DL580 Gen10, DX360 Gen10, DX380 Gen10 and DX560 Gen10 servers that require 288-pin RDIMMs. The modules run at 1.2 V with CL21 latency and 2Rx4 organisation.

Suited for compatible ProLiant servers

The kit fits the listed Gen10 ProLiant models that accept registered ECC DDR4 RDIMMs. It will not work in standard desktop PCs or consumer motherboards that only support unbuffered memory. Systems requiring load-reduced ECC DIMMs or a different pin count cannot use these modules.

256 GB capacity with speed headroom

Four 64 GB DIMMs provide 256 GB total capacity for memory-intensive server workloads. The DDR4-2933 rating is backward compatible with 2133, 2400 and 2666 MHz bus speeds, so the kit will operate at the highest speed the platform allows. Maximum supported capacity depends on the specific server configuration.

Questions about this item

What HP ProLiant Gen10 server must I already have to install this 256GB DDR4 2933 ECC RDIMM kit?

This kit is validated for HP ProLiant DL560 Gen10, DL580 Gen10, DX360 Gen10, DX380 Gen10 and DX560 Gen10 servers. It requires a 288-pin DDR4 RDIMM slot and will not work in standard desktops.

Can I mix these 64GB 2Rx4 registered modules with the 2133MHz, 2400MHz or 2666MHz DDR4 DIMMs already in my ProLiant?

Yes. The modules are backward compatible with 2133MHz, 2400MHz and 2666MHz DDR4 speeds. The system will run all installed DIMMs at the lowest common speed.

How do I confirm the 256GB kit is running at 2933MHz CL21 with ECC active after installation?

Check the BIOS memory configuration or OS tools such as dmidecode on Linux or Task Manager on Windows. They should report 256GB total, 2933MHz speed, CL21 latency and ECC Registered status.
