Compatible Server Memory Upgrade

This 256GB kit provides four 64GB DDR4 3200 ECC Registered RDIMM modules for HP ProLiant Gen10 Plus servers. It replaces specific HP part numbers including P43170-B21 and P06035-B21 for validated compatibility.

Suited For Registered ECC Workloads

The modules suit administrators expanding memory in DL325, DL345, DL360, DL365 and DL380 Gen10 Plus systems. Builders using standard desktop motherboards, unbuffered DIMMs or load-reduced memory cannot use this kit.

Four-Module Registered Configuration

The 288-pin RDIMMs operate at 1.2V with CL22 latency and 2Rx4 organisation. Installing the matched quartet fills four slots for multi-channel operation while the registered buffer reduces electrical load on the server memory controller.

Questions about this item

Does this 256 GB DDR4 3200 kit need an HP ProLiant DL380 Gen10 Plus server to work?

Yes, this OWC kit is built for HP ProLiant DL325 Gen10 Plus v2, DL345 Gen10 Plus, DL360 Gen10 Plus, DL365 Gen10 Plus and DL380 Gen10 Plus servers. It will not fit standard desktops or other platforms.

Will these 64 GB 2Rx4 CL22 registered modules run if I keep slower ECC registered DIMMs in the same DL360 Gen10 Plus?

The modules are DDR4 3200 PC4-25600 CL22 1.2 V ECC registered 2Rx4. They will operate at the speed of the slowest installed DIMMs and must not be mixed with unbuffered or load-reduced memory.

How can I confirm the 256 GB kit is running at DDR4 3200 CL22 after I install it?

Check the BIOS or iLO memory inventory — it should show four 64 GB DIMMs at 3200 MT/s with CL22 timings and ECC registered status.
