512GB DDR4 2933 ECC LRDIMM kit

This kit provides 512GB of DDR4 2933 ECC load-reduced memory across four 128GB modules. It is built for the HP ProLiant XL270d Gen10 server platform. The modules operate at 1.2V with CL21 latency and an 8Rx4 rank configuration. Buyers using standard desktop boards or consumer workstations cannot install this memory.

ECC load-reduced operation

The load-reduced design lowers electrical load on the server memory bus, allowing the high 512GB capacity to run at DDR4 2933. ECC corrects single-bit errors to protect data integrity in critical workloads. The kit replaces HP part numbers including P12404-B21 and P00928-B21. It cannot be mixed with unbuffered or standard registered DIMMs in the same system.

Capacity headroom and speed limits

Four 128GB modules fill four slots to reach the 512GB total, leaving no empty slots for further expansion on a four-channel controller. The modules also run at 2133, 2400 and 2666MHz when the platform requires lower speeds. Workloads needing more than 512GB or faster than 2933MT/s will exceed what this kit can deliver.

Questions sur cet article

Will the 128GB LRDIMM modules need any firmware updates or heat-spreader maintenance over time?

The modules have no heat spreader and run at standard 1.2V; no firmware updates are required for the memory itself.

What limit appears first when the 8Rx4 LRDIMMs run at 2933 MHz continuously in the XL270d Gen10?

The memory controller's maximum supported speed of 2933 MHz is the first ceiling; the kit is rated for that speed at CL21.

How much power and heat do the four 128GB LRDIMMs generate when the server runs all day?

Each module operates at 1.2V DDR4 voltage; total power draw scales with the four-module kit under sustained load.
