Brute Networks 16GB DDR4-2666 ECC Registered RDIMM 1Rx4 CL15 1.2V 01DE972

Lenovo-Compatible 16 GB DDR4-2666 RDIMM

This Brute Networks module adds 16 GB of registered ECC memory to compatible Lenovo servers. It is built for administrators who need to expand capacity in existing rack-mount or tower systems without replacing the platform. The stick uses major-brand DRAM and meets OEM specifications. Buyers who need unbuffered UDIMMs or higher-frequency kits should look elsewhere.

288-pin DDR4 2666 CL15 registered spec

The single decisive figure is the DDR4-2666 (PC4-21300) registered ECC interface with CL15 latency and 1Rx4 organisation. Only systems that accept 288-pin RDIMMs at this exact speed and rank configuration will recognise the module. Mixing with unbuffered memory or different speeds will prevent boot or force a down-clock.

1.2 V standard-voltage thermals

Operating at 1.20 V, the module runs within standard DDR4 power limits and does not require additional cooling beyond normal server airflow. Registered buffering reduces electrical load on the memory controller, helping stability in fully populated channels. Noise remains unchanged because the DIMM has no moving parts.
