HPE 809085-091 4GB DDR4 LRDIMM module

This HPE 809085-091 module provides 4GB of DDR4 memory in an LRDIMM form factor. It is designed for servers and workstations that require registered load-reduced memory. The multicolor circuit board identifies the part in dense chassis environments. Buyers replacing or expanding compatible HPE system memory will use this part.

DDR4 LRDIMM capacity and platform limits

DDR4 LRDIMM technology allows higher per-slot densities than standard RDIMMs, but total system memory remains capped by the processor memory controller and the motherboard slot count. Maximum supported speed depends on the specific CPU generation and the number of populated channels. Mixing LRDIMMs with other DIMM types on the same channel is not supported.

Verify slot type and CPU support before ordering

Confirm that your server motherboard has DDR4 LRDIMM slots and that the installed processors support load-reduced modules. Check the system service manual for the correct population order and maximum module count per channel. Ensure the firmware revision meets the minimum requirement for this part number.

Perguntas sobre este artigo

Should I pick the 4GB DDR4 LRDIMM or another capacity for my server?

Choose the 4GB DDR4 LRDIMM when your system requires registered load-reduced modules at this density; match the exact part number 809085-091 to your server's qualified vendor list.

What does the 4GB DDR4 rating deliver once the module is installed?

The module provides 4GB of DDR4 SDRAM capacity in a load-reduced DIMM form factor, allowing higher memory densities per channel on compatible HPE servers.

Does the DDR4 LRDIMM interface limit speed or rank count in practice?

DDR4 LRDIMM buffers the data lines, reducing electrical load so the memory controller can support more ranks per channel without downclocking.
