512GB DDR4 2933 ECC RDIMM kit

This 512GB kit contains eight 64GB DDR4 2933 registered ECC DIMMs built for HP ProLiant Gen10 servers. It targets administrators who need maximum registered memory capacity in BL460c, DL325, DL360, DL380 or DL385 platforms.

Replaces HP part numbers P19045 and P00930 series

The modules replace HP part numbers such as P19045-K21, P19045-B21, P00930-H21 and P00930-B21. The jump is worth it when existing slots hold smaller registered DIMMs and the workload demands the full 512GB ceiling.

Eight 64GB dual-rank modules at 1.2V

The 2Rx4 organisation and CL21 timing deliver 512GB of registered ECC headroom for virtualisation and large databases. It runs out when the platform requires load-reduced DIMMs or when unbuffered memory is the only supported type.

Questions about this item

Does the 288-pin DDR4 ECC RDIMM fit the HP ProLiant DL380 Gen10 memory slots?

Yes, the 288-pin DDR4 ECC RDIMM modules match the DIMM slots on the HP ProLiant DL380 Gen10 and the other listed Gen10 servers.

What is the correct order to install the eight 64 GB modules across the CPU channels?

Populate each memory channel evenly by filling the same slot number on every channel before moving to the next slot, following the server's population guide.

When should the registered ECC RDIMMs be replaced if ECC correctable error counts start rising?

Replace modules when the system logs show a sustained increase in correctable ECC errors or when the platform health alert indicates a memory degradation threshold.
