Lenovo Compatible 8GB DDR4-2133 ECC UDIMM

This 8GB DDR4-2133 ECC UDIMM is built for Lenovo servers and workstations that require error-correcting memory. It operates at 1.20V with a CAS latency of CL15 and uses a 2Rx8 rank configuration on a 288-pin PCB. The module is validated for full compatibility with systems specifying part number 4X70K14184.

Suited for admins expanding memory in supported

It fits administrators who need to add ECC capacity to compatible Lenovo hardware without using OEM-labelled sticks. Buyers whose systems demand registered DIMMs, higher speeds, or larger single-module capacities should look at other options. Non-ECC consumer boards and laptops that only accept SO-DIMMs cannot use this module.

Major-brand chips and lifetime guarantee change

Each stick uses Samsung, SK Hynix or Micron components and is tested to match the OEM specification, so the factory warranty remains intact. The lifetime warranty and 60-day return window replace the shorter coverage often tied to third-party memory. Orders are filled with identically matched modules to avoid mixed-rank issues.

Questions about this item

Does my Lenovo server need free 288-pin DDR4 slots to use this 8GB ECC UDIMM?

Yes, this module fits standard 288-pin DDR4 DIMM sockets and requires an available unbuffered ECC slot on a compatible Lenovo platform.

Will this DDR4-2133 CL15 1.20V stick run correctly alongside slower DDR4 modules already installed?

The system will operate all modules at the speed and timings of the slowest installed kit; mixing different speeds or latencies is functional but not optimal.

How can I verify the module is detected as 8GB ECC at 2133 MHz after installation?

Check the BIOS memory summary or run a tool such as dmidecode; it should report 8 GB, DDR4-2133, ECC enabled, and CL15 timings.
