Server-grade 128 GB DDR4 module

This Kingston DDR4 LRDIMM provides 128 GB of ECC memory for servers and workstations that require large-capacity registered modules. The quad-rank design and 288-pin interface suit platforms built for high-density memory configurations. It operates at 3200 MHz with a CAS latency of CL22. The module runs at 1.20 V.

ECC and LRDIMM architecture

On-die ECC detects and corrects single-bit errors to protect data integrity in mission-critical workloads. The load-reduced DIMM topology reduces electrical loading on the memory bus, allowing the system to populate more slots at rated speed. Quad-rank organisation increases density per slot without changing the physical form factor. These traits support stable operation in multi-socket servers.

3200 MHz DDR4 speed rating

The PC4-25600 rating confirms a 3200 MHz data rate, which is the single specification that determines whether this module matches the platform's memory controller. Systems qualified for DDR4-3200 will run at full frequency; slower platforms will down-clock automatically. Buyers who need a different data rate or a non-ECC UDIMM format should select another part.

Questions about this item

Will the 288-pin LRDIMM slot require any special cleaning or contact maintenance over time?

Standard DDR4 LRDIMM contacts only need occasional dust removal with compressed air; no special cleaning or replacement schedule is required for the 288-pin edge connector.

What thermal limit appears first when this 128 GB module runs at 3200 MHz continuously?

The 1.20 V operating voltage keeps power draw low, so the module typically hits its JEDEC thermal envelope before any voltage-related throttling occurs.

How much fan noise or extra heat should I expect from a 128 GB CL22 kit running all day?

At 1.20 V the module adds minimal heat; a normal server airflow path handles it without increasing fan speed or audible noise.
