64GB DDR4-2400 LRDIMM for Lenovo servers

This 64GB DDR4-2400 PC4-19200 module uses a 288-pin LRDIMM form factor with 4Rx4 organisation. It operates at 1.20V with a CAS latency of CL15 and includes ECC error correction. The load-reduced design places less electrical load on the memory bus than standard registered DIMMs. It is built with major-brand DRAM chips and matches Lenovo part number 4X70G88321.

Replaces lower-capacity DDR4 LRDIMMs

Upgrading makes sense when your Lenovo server runs near its memory ceiling and swapping or paging slows virtual machines or databases. Adding these 64GB modules lets you maximise the installed capacity supported by the platform without replacing the host. The jump is worth it when application responsiveness is limited by physical RAM rather than by CPU or storage throughput.

Sustained load behaviour

The load-reduced buffer reduces electrical loading on the memory controller during continuous read and write streams. This helps maintain signal integrity at the rated 2400 MT/s speed when all channels are populated. ECC corrects single-bit errors in real time, preventing data corruption during long-running workloads. The 1.20V operation keeps power draw steady under sustained utilisation.

Questions about this item

Will the 288-pin DDR4 LRDIMM fit my server's memory slots?

The module uses the standard 288-pin DDR4 form factor and 1.20V voltage required by compatible server platforms.

What is the correct installation sequence for 4Rx4 load-reduced modules?

Populate slots per the server manufacturer's population guide; the common error is mixing 4Rx4 LRDIMMs with standard RDIMMs in the same channel.

When should I consider replacing these 64GB LRDIMMs?

Replace if ECC correctable error counts rise steadily or if the server logs uncorrectable memory errors during POST or operation.
