64GB DDR4 2666 LRDIMM for servers

This 64GB DDR4 2666MHz CL19 LRDIMM module is built for Supermicro platforms that require ECC Load Reduced memory. It targets administrators expanding capacity in qualified systems. The 288-pin form factor fits standard DDR4 server slots. Buyers needing non-ECC or unbuffered DIMMs should look elsewhere.

64GB capacity with quad-rank headroom

The single module delivers 64GB using a 4Rx4 organisation, allowing high density per slot. It operates at 2666MHz with CL19 latency and 1.20V voltage. Systems that cannot address quad-rank LRDIMMs or that max out below 64GB per slot will not support this module.

DDR4 2666 interface practical limits

The PC4-21300 rating sets the peak transfer rate for this DDR4 generation. Load Reduced buffering reduces electrical load on the memory controller, enabling larger populations. Platforms limited to lower DDR4 speeds or to registered DIMMs without load reduction cannot use this memory.

Questions about this item

Will this 2666MHz LRDIMM work alongside slower DDR4 modules I already have installed?

The module runs at 2666MHz CL19 1.20V; if your existing DDR4 DIMMs are slower the system will clock all sticks down to the lowest common speed and tightest timings.

How can I verify the ECC Load Reduced function is active after installation?

Check the BIOS memory information screen — it should report 64GB, 4Rx4 organisation, ECC enabled and a Load Reduced DIMM type at 2666MHz.

Does the package include a single 64GB stick or a kit, and are any extra parts required?

One 288-pin LRDIMM module is supplied; no additional components are needed, just an available DDR4 LRDIMM slot on a compatible Supermicro platform.
