NEMIX RAM
A 32 GB DDR4 2666 ECC LRDIMM module with CL19 latency and 1.2 V operation for HPE ProLiant DL325 G10 servers
This 32GB DDR4 2666 ECC LRDIMM module is built for the HPE ProLiant DL325 G10 server. It uses a load-reduced design with 2Rx4 organisation to support high-density memory configurations. The 288-pin form factor operates at 1.2V with a CAS latency of CL19. IT teams select this part when expanding capacity in compatible HPE platforms.
The load-reduced architecture lowers electrical loading on the memory bus, helping signal integrity when all slots are populated. ECC circuitry detects and corrects single-bit errors during continuous operation. Modules are stress tested under load before shipping to verify stability in multi-threaded server workloads. The 1.2V operating voltage keeps power draw consistent across extended duty cycles.
Confirm the DL325 G10 has an available 288-pin DDR4 LRDIMM slot and that the planned configuration follows HPE population guidelines for load-reduced modules. Mixing LRDIMM with standard RDIMM or UDIMM types is not supported. Check the server documentation for maximum total capacity and supported rank combinations per channel. BIOS version may affect recognition of 32GB density modules.

The module operates at 1.2V, which is standard DDR4 voltage; actual power draw depends on the HPE ProLiant DL325 G10 platform and workload, not the DIMM alone.
The server must support DDR4 2666 LRDIMM memory, have an available 288-pin DIMM slot, and run a BIOS that recognises 2Rx4 ECC LRDIMM modules.
The module is rated DDR4 2666 CL19; the system will clock all installed DIMMs to the lowest common speed and latency supported by the platform.
