OWC 512GB DDR4 ECC LRDIMM Kit

This kit provides 512GB of DDR4 memory across four 128GB load-reduced DIMMs rated at 3200 MT/s with CL22 latency. It is built specifically for the HP Apollo 4200 Gen10 Plus server platform. The modules operate at 1.2V and carry ECC load-reduced buffering for data integrity in multi-socket systems. They will not work in standard desktop computers.

Compatibility and installation notes

The 288-pin LRDIMMs replace HP part numbers such as P06037-B21 and P43171-B21 and are backward compatible with 2133, 2400, 2666 and 2933 MT/s bus speeds. Mixing these modules with unbuffered or registered ECC DIMMs is not supported. No heat spreaders are fitted, so airflow in the chassis must handle thermal management. The kit is validated for server, workstation and NAS environments.

Who should buy this and who should not

IT teams upgrading or repairing an HP Apollo 4200 Gen10 Plus will match the factory configuration exactly. Buyers needing memory for consumer motherboards, laptops or non-HP servers should look elsewhere because the load-reduced ECC design and pin-out are incompatible. Systems requiring registered ECC instead of load-reduced ECC also cannot use this kit.

Questions about this item

Will the 4Rx4 ECC LRDIMM modules need replacement after a certain number of write cycles?

DDR4 ECC LRDIMM memory does not have a write-cycle wear limit; the 512 GB kit is built to last the usable life of the HP Apollo 4200 Gen10 Plus.

What limit appears first when the 512 GB kit runs at 3200 MHz CL22 continuously?

The memory controller’s maximum supported speed and rank population rules for the Apollo 4200 Gen10 Plus define the practical ceiling, not the modules themselves.

How much heat and power do the four 128 GB 1.2 V LRDIMMs generate under all-day load?

Each module operates at 1.2 V without a heat spreader; total power draw and thermal output follow the DDR4 3200 JEDEC specification for 4Rx4 LRDIMMs.
