Lenovo 8GB DDR4-2133 UDIMM

This 8GB DDR4-2133 UDIMM module is designed for Lenovo servers that accept unbuffered, non-ECC memory. It installs as a direct replacement for part number 4X70K09921 and is built with major-brand DRAM components. The stick operates at 1.20V and runs at PC4-17000 speed with CL15 latency. Buyers receive a new, tested module backed by a lifetime guarantee from the supplier.

Servers needing 8GB non-ECC UDIMMs

This module suits administrators upgrading or repairing compatible Lenovo platforms that specifically require unregistered, non-ECC DDR4-2133 memory. It will not work in systems that demand registered or ECC DIMMs, nor in boards limited to lower-density chips or different voltage requirements. Buyers needing higher capacities, registered modules or error-correcting memory should select a different part.

DDR4-2133 CL15 1.20V specification

The decisive specification is the DDR4-2133 CL15 1.20V unbuffered non-ECC UDIMM profile. Only systems qualified for this exact speed, latency, voltage and module type will accept the part without configuration issues. Verify the server documentation matches these parameters before ordering.
