High-density server memory upgrade

This 64GB DDR4 LRDIMM delivers registered ECC operation at 2400MHz with a 4Rx4 organisation. It is built for administrators who need to maximise installed capacity in compatible Lenovo platforms without replacing the server chassis.

Sustained load behaviour

The module runs at 1.20V and CL15 latency while maintaining error correction across all ranks during continuous workloads. Registered buffering reduces electrical load on the memory controller, helping stability when every slot is populated with high-capacity sticks.

DDR4 platform limits

DDR4 architecture caps per-module density and signal integrity at this speed grade, so total system memory remains bound by the motherboard slot count and chipset capabilities. Buyers who need larger individual modules or higher transfer rates must move to a newer memory generation.

Questions about this item

How much heat does a 1.2V 64GB LRDIMM add when the server runs all day?

At 1.2V the module draws minimal power for its 64GB capacity, so thermal load stays low even under continuous 2400MHz operation.

What must the motherboard already support for this 4Rx4 registered ECC module to work?

The board needs DDR4 slots that accept 4Rx4 LRDIMMs, registered ECC signalling, and PC4-19200 speed at CL15.

Will this CL15 2400MHz stick run stably beside older DDR4 modules rated at lower speeds?

Yes — the module will down-clock to match the slowest installed kit while keeping ECC and registered operation intact.
