Server memory kit for HP ProLiant Gen10

This kit supplies 1TB of DDR4 ECC Load Reduced memory across eight 128GB modules. It is built for HP ProLiant DL560 Gen10, DL580 Gen10, DX360 Gen10, DX380 Gen10 and DX560 Gen10 servers that require registered LRDIMM technology. Standard desktop systems cannot use these modules.

Eight matched modules simplify large-capacity

The kit delivers eight identical 288-pin LRDIMMs rated at 2933 MT/s with CL21 latency at 1.2V. Installing the full set populates multiple channels at once, letting the memory controller run at its rated speed without mixing ranks or speeds. Each module carries ECC load-reduced buffering for signal integrity in dense configurations.

Verify your server model and memory population rules

This memory fits only the listed HP ProLiant Gen10 platforms and replaces specific HP part numbers including P19047 and P11040 series. It will not work with unbuffered or standard registered ECC DIMMs, so all slots in a channel must use the same LRDIMM type. Check your server’s service guide for supported DIMM-per-channel limits and required firmware revisions before ordering.

Questions sur cet article

Will the 1.2V DDR4 LRDIMMs need active cooling or replacement after extended server use?

These modules have no heat spreader and run at the standard 1.2V JEDEC voltage; in a properly cooled ProLiant chassis they operate within spec for the system lifetime.

At sustained load does the CL21 latency or the 2933 MT/s data rate become the bottleneck first?

The rated speed is 2933 MT/s (PC4-23400) with CL21 timing; the memory controller in the supported Gen10 platforms sets the ceiling, so neither parameter exceeds the other in normal operation.

How much power and heat do the eight 128 GB 4Rx4 LRDIMMs add when the server runs all day?

Each module draws 1.2V at the JEDEC DDR4 LRDIMM current level; total kit power scales with all eight ranks active, and the ProLiant airflow design handles the resulting heat.
