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.

Questions about this item

What does the 2666 MT/s rating mean once the module is installed in a server?

The module runs at DDR4-2666 speed when the platform supports it; the memory controller sets the final operating frequency.

What does the PC4-21300 designation tell me about the interface and its practical limit?

PC4-21300 is the DDR4-2666 JEDEC standard; peak bandwidth per module is defined by that specification.

What physical slot and keying does this 288-pin RDIMM need to fit and mount?

It requires a standard 288-pin DDR4 DIMM slot with the registered key notch; the module is 1Rx4 ECC registered.
