64GB DDR4-2666 LRDIMM for HP servers

This 288-pin DDR4 module delivers 64GB at 2666 MT/s with CL15 latency and 1.20V operation. It uses load-reduced ECC technology and a 4Rx4 organisation built from major-brand DRAM. The part matches HP part number 868844-001 and is guaranteed compatible with systems requiring this specification.

Suited for administrators expanding HP ProLiant

Buyers who need a different capacity, a standard registered DIMM instead of load-reduced, or a voltage other than 1.20V should look elsewhere. Systems that do not support 4Rx4 LRDIMMs or DDR4-2666 speeds cannot use this module.

The deciding spec is the 4Rx4 load-reduced ECC

This rank and buffering combination determines whether the memory controller can address the full 64GB. Verify the server’s qualified vendor list for 4Rx4 LRDIMM support before purchase.

Questions about this item

Should I pick the 64GB 4Rx4 LRDIMM or a lower-capacity RDIMM?

Choose the 64GB 4Rx4 LRDIMM when your server has a limited number of slots and you need maximum capacity per module; the load-reduced design lowers electrical load on the memory bus so more ranks can be populated.

What does the 2666 MT/s rating actually deliver in a live server?

The module runs at 2666 MT/s with CL15 timing at 1.20V, providing 21300 MB/s peak bandwidth per module; real-world throughput depends on the CPU memory controller and how many channels are populated.

How does the 288-pin DDR4 LRDIMM interface limit speed and capacity?

The 288-pin DDR4 interface caps this module at 2666 MT/s and 1.20V; the LRDIMM buffer allows 4Rx4 organisation so a single stick delivers 64GB without exceeding the electrical load limits of standard RDIMM slots.
