32GB DDR4-3200 ECC RDIMM for servers

This module delivers 32GB of DDR4 memory rated at 3200MHz with ECC and registered buffering. It is built for Lenovo servers that require 2Rx4 organisation and PC4-25600 speed. The part matches Lenovo part number 02JK237 for direct replacement.

2Rx4 registered design with major-brand chipset

The stick uses a major-brand chipset in a 2Rx4 layout, giving stable signal integrity on loaded memory channels. Registered buffering reduces electrical load on the server memory controller. ECC circuitry detects and corrects single-bit errors during operation.

DDR4-3200 speed ceiling and registered latency

The DDR4-3200 interface caps bandwidth at the PC4-25600 data rate, so faster memory controllers cannot exceed this throughput. Registered timing adds one cycle of latency compared with unbuffered modules. Systems needing higher frequency or lower latency must use a different memory standard.
