Lenovo Compatible DDR4-2666 Server Module

This Brute Networks module is an 8GB DDR4-2666 unbuffered ECC DIMM built to match Lenovo part 4X70Z50946. It uses major-brand chips from Samsung, SK Hynix or Micron and runs at 1.2V across 288 pins. The stick is 100 per cent tested for compatibility and ships with a lifetime warranty.

Ideal for single-slot ECC upgrades.

The 1Rx8 unbuffered design suits servers and workstations that accept standard UDIMM ECC memory and need a direct Lenovo-compatible replacement. Systems requiring registered or load-reduced DIMMs cannot use this module. Buyers needing higher capacities or multiple matched kits should verify slot counts and maximum supported memory per channel before ordering.

Matched modules simplify multi-slot population

Every order is filled with identically matched sticks, eliminating the risk of mixed die revisions that can cause training failures. The 60 per cent cost saving versus OEM list price lets IT teams extend existing infrastructure without budget strain. Lifetime warranty coverage mirrors factory support terms, so the original server warranty remains intact.

Questions about this item

Does my server need to support 288-pin DDR4-2666 unbuffered ECC memory to use this 8GB module?

Yes, the system must accept 288-pin DDR4 SDRAM running at 2666 MT/s with 1.20V unbuffered ECC 1Rx8 organisation.

Can I add this stick to a Lenovo server that already has factory 2666 MT/s DDR4 ECC modules installed?

The module is 100% Lenovo compatible and validated to match OEM specifications, so it will operate alongside existing factory memory at the same 2666 MT/s speed.

How can I verify the module is running at PC4-21300 after installation?

Check the BIOS or OS memory report; it should show 2666 MT/s, 1.20V, ECC enabled and a single-rank 1Rx8 configuration.
