Dell-compatible 64 GB DDR4-2666 ECC LRDIMM with 4Rx4 rank and 1.2 V operation
This 64GB DDR4-2666 ECC LRDIMM uses a 288-pin form factor and runs at 1.2V. It is built to match Dell part number A9816030 and carries a lifetime warranty. The module is assembled with major-brand DRAM chips and is rated PC4-21300.
IT teams that need to maximise installed memory in supported Dell platforms will benefit from the 4Rx4 load-reduced design. Buyers whose systems require standard RDIMMs or lower capacities should verify the memory specification before ordering.
The use of Samsung, SK Hynix or Micron components means the module comes from the same suppliers as Dell-branded units. This equivalence helps maintain existing service contracts while adding capacity. The load-reduced architecture reduces electrical load on the memory bus.

Yes, the module is a 288-pin DDR4 LRDIMM with ECC and 4Rx4 organisation, so the system must support load-reduced registered memory and error correction.
Mixing LRDIMMs with standard RDIMMs is not supported; all slots must use the same registered memory type for the server to operate correctly.
Check the BIOS memory configuration or use a tool such as dmidecode to confirm the speed shows 2666 MT/s and the ECC status is enabled.
