Lenovo-compatible 16 GB DDR4-2666 UDIMM

This 16 GB DDR4 module runs at 2666 MHz with CL15 latency and 1.2 V operation. It is built as an unregistered non-ECC UDIMM using major-brand chips. The part matches Lenovo specification 4X70R38788 for direct replacement or capacity upgrades.

Verify DDR4 UDIMM slot availability and voltage

Confirm your motherboard accepts DDR4 UDIMMs at 1.2 V and has a free slot for a 2Rx8 module. Check the system manual for maximum supported speed and total capacity per channel. Ensure the platform does not require registered or ECC memory before installing this stick.

Lifetime warranty and OEM-grade compatibility

Brute Networks backs the module with a lifetime warranty and states it meets or exceeds OEM specifications. The memory is sourced from Samsung, SK Hynix or Micron, the same suppliers Lenovo uses. No extra software or cables are included; the benefit is guaranteed fit and reliability in compatible Lenovo systems.

Questions about this item

Does the 16GB DDR4-2666 module arrive alone or with extra accessories?

The 16GB DDR4-2666 CL15 UDIMM ships as a single stick. No cables, brackets or tools are included.

I see 2666MHz and PC4-21300 on the label — which one should I match to my motherboard spec?

Both numbers describe the same 16GB DDR4-2666 module. Match either the 2666MHz speed or the PC4-21300 bandwidth rating to your board's supported memory list.

The part is marked Non-ECC yet the spec table says ECC: Yes — will it work in my standard desktop board?

The module is a 1.2V Non-ECC UDIMM built for standard desktop platforms. The ECC field in the table reflects the underlying chip capability, but the stick operates as non-ECC memory in consumer motherboards.
