Server ECC RDIMM kit

This OWC kit supplies 256 GB of DDR4 ECC registered memory in four 64 GB modules. It is built for HP ProLiant Gen10 servers such as the BL460c, DL325, DL360, DL380 and DL385. The modules will not work in standard desktop computers and cannot be mixed with unbuffered or load-reduced DIMMs.

Registered ECC requirement

Each module is a 288-pin DDR4 RDIMM with 2Rx4 organisation, CL21 latency and 1.2 V operation. The registered ECC design is the single specification that decides compatibility; only systems that accept registered ECC DDR4 at 2933 MT/s can use this kit.

256 GB capacity ceiling

Four 64 GB DIMMs fill four slots and give 256 GB total, suitable for virtualization hosts, large databases and memory-intensive workloads. The kit runs at 2933 MT/s and is backward compatible with 2133, 2400 and 2666 MT/s buses. Buyers who need more than 256 GB or who require unbuffered or load-reduced memory must choose a different product.

Questions about this item

Will the 2933 MHz rated speed run at that frequency in my HP ProLiant DL380 Gen10?

The modules are rated for DDR4 2933 (PC4-23400). The server's memory controller and installed CPU determine the actual operating speed; populated DIMM slots and BIOS settings can lower the effective frequency.

What does PC4-23400 mean for this ECC Registered kit?

PC4-23400 is the JEDEC standard designation for DDR4 2933. It identifies the data-rate tier and ensures the modules meet the timing (CL21) and voltage (1.2 V) requirements for registered server memory.

Do these 288-pin RDIMMs fit the memory slots in an HP ProLiant BL460c Gen10 blade?

Yes. The kit uses the standard 288-pin DDR4 RDIMM form factor required by the listed HP ProLiant Gen10 servers, including the BL460c, DL325, DL360, DL380 and DL385 models.
