A-Tech 64GB DDR4 2666MHz ECC LRDIMM 4Rx4 HP L09287-850 Server RAM

64GB DDR4 2666MHz ECC LRDIMM for HP L09287-850

This 64GB module is a compatible replacement for HP L09287-850. It uses DDR4 2666MHz PC4-21300 ECC Load Reduced DIMM technology with a 4Rx4 rank configuration. The module operates at 1.2V standard voltage and features CL19 CAS latency. It is designed for server and workstation systems requiring high-capacity registered memory.

Verify DDR4 LRDIMM slot compatibility

Before ordering, confirm your system supports DDR4 ECC Load Reduced DIMMs and accepts 4Rx4 rank modules. The module uses a 288-pin DIMM form factor, not the 262-pin SO-DIMM variant. Check your motherboard or server documentation for maximum supported capacity per slot and qualified vendor lists. Ensure the BIOS recognises LRDIMM technology at 2666MHz speed.

Fills a single DDR4 DIMM slot in server chassis

This single 64GB module occupies one 288-pin DDR4 DIMM slot, freeing remaining slots for additional capacity. The Load Reduced design reduces electrical load on the memory controller, allowing higher total system memory. It requires a platform that supports ECC LRDIMM operation at 1.2V. No additional cooling or power connectors are needed beyond the standard DIMM socket.
