Lenovo ThinkSystem compatible ECC UDIMM

This 8 GB DDR4 2666 module is built for Lenovo ThinkSystem servers and workstations that require ECC unbuffered memory. It fits 288-pin DDR4 slots and operates at 1.2 V with CL19 latency. The single-rank 1Rx8 organisation suits platforms qualified for the 4ZC7A08696 part number.

Single module ready for installation

The package contains one 8 GB stick with no heat spreader, keeping the profile low for dense server chassis. No extra cables, brackets or software are included because the module installs directly into a standard UDIMM socket. The bare PCB design is typical for OEM-qualified server memory.

ECC unbuffered with 1Rx8 rank

Error-correcting code protects data integrity in mission-critical workloads while the unbuffered design keeps latency low for compatible ThinkSystem platforms. The 1Rx8 rank configuration must match the system's qualified memory list; boards that require registered or dual-rank modules will not accept this part.

Questions sur cet article

Will the single-rank 1Rx8 ECC modules need any firmware updates or scheduled replacement after installation?

No firmware updates or scheduled replacements are required; the ECC UDIMM runs at 1.20 V with CL19 timing and is validated for continuous server workloads.

What thermal limit appears first when the memory runs at 2666 MT/s under sustained load?

The module has no heat spreader, so the DRAM junction temperature reaches its rated maximum before any other component becomes a bottleneck.

How much power does the 8 GB stick draw and how loud is it during all-day operation?

At 1.2 V the stick consumes only a few watts, produces no audible noise, and stays within standard DDR4 thermal limits without active cooling.
