Lenovo 64 GB TruDDR4 Server Memory

This 64 GB registered ECC DIMM is built for Lenovo ThinkSystem servers. It targets administrators who need maximum capacity per slot in supported 2U and 4U platforms. The module operates at 1.20 V and conforms to the DDR4-3200 standard.

DDR4-3200 dual-rank registered ECC

The single specification that decides fitment is the DDR4-3200 dual-rank registered ECC configuration with 288 pins. Only systems qualified for this exact rank and signal-processing type will initialise the module correctly.

Thermals and power in normal use

At 1.20 V the module runs within standard DDR4 thermal limits during typical server workloads. Registered buffering reduces electrical load on the memory controller, keeping power draw steady without active cooling requirements.
