4GB DDR4 2133MHz SODIMM for ThinkCentre

This 4GB DDR4 module runs at 2133MHz with CL15 latency and 1.2V operation. It uses a 260-pin SODIMM form factor and is unbuffered non-ECC memory. The module is validated for specific Lenovo ThinkCentre systems including M700 Tiny, M700z, M800z, M900z and X1 models.

Suitable for compatible ThinkCentre upgrades

Owners of the listed ThinkCentre models can install this module to add 4GB of system memory. The JEDEC-compliant design ensures reliable operation within supported platforms. Systems requiring ECC registered memory, higher capacities per module, or different DDR generations cannot use this SODIMM.

Handles everyday multitasking loads

The 4GB capacity provides headroom for typical office applications, web browsing and light multitasking. Memory-intensive workloads such as virtualisation, large dataset processing or modern gaming will exceed the available capacity. The single-rank 1Rx8 organisation works within the memory controller limits of the validated platforms.

Questions about this item

Does my Lenovo ThinkCentre need an available 260-pin SODIMM slot to install this module?

Yes, the module uses the 260-pin DDR4 SODIMM form factor, so an empty slot of that type is required.

Will this DDR4 2133 MHz CL15 stick run at its rated speed alongside slower DDR4 modules already in the system?

The memory will operate at the speed of the slowest installed module, so mixing with slower DDR4 reduces overall performance.

How can I confirm the 4 GB capacity is recognised after fitting the 1Rx8 module?

Check the BIOS memory summary or the operating-system task manager; both should show the additional 4 GB at 2133 MHz.
