Lenovo-compatible 64 GB DDR4 ECC RDIMM

This registered DDR4 module delivers 64 GB of error-correcting memory for Lenovo servers and workstations. It operates at 2666 MHz with a CL19 latency and runs on 1.2 V. The 288-pin RDIMM form factor fits compatible Lenovo platforms that require registered ECC memory.

Sustained load behaviour with 4Rx4 organisation

The 4Rx4 rank configuration spreads memory accesses across four ranks of x4 chips, helping to maintain throughput during prolonged workloads. Registered buffering reduces electrical load on the memory controller, supporting stable operation in multi-module server configurations. ECC circuitry detects and corrects single-bit errors throughout continuous operation.

Single specification that decides fit: 4Rx4

This module uses a 4Rx4 organisation and registered ECC signalling that must match the platform's memory controller requirements. Systems expecting a different rank structure, unbuffered DIMMs or non-ECC memory will not support this part. Verify the server or workstation documentation for 4Rx4 RDIMM compatibility before purchase.

Spurningar um þessa vöru

How much power does the 1.2V DDR4 2666 module draw when the server runs continuously?

The module operates at 1.20V, the standard DDR4 voltage, so power draw stays within normal registered DIMM limits for 2666 MT/s operation.

What motherboard slot and chipset support are required to install this 288-pin RDIMM?

A server or workstation motherboard with DDR4 RDIMM slots, registered memory support, and ECC capability is needed; the module is validated for Lenovo systems using part number 4X77A78614.

Will this 4Rx4 ECC RDIMM work alongside existing 2Rx4 or 1Rx4 sticks in the same Lenovo server?

Mixing ranks is platform-dependent; the memory controller must support 4Rx4 population rules, so consult the system manual before adding this module to channels with different rank configurations.
