4GB DDR4 UDIMM for Lenovo IdeaCentre

This 4 GB DDR4 module is built for Lenovo IdeaCentre 700-25ISH, 710-25ISH and Y900-34ISZ desktops. It plugs into a standard 288-pin UDIMM slot and runs at 2133 MHz with CL15 latency. The unbuffered, non-ECC design matches the original system specification.

Steady operation at rated speed

The module operates at 1.2 V and complies with JEDEC PC4-17000 timings, so it maintains its 2133 MHz data rate during extended workloads. No heat spreader is fitted, relying on case airflow to keep temperatures stable under continuous use.

Single-rank 1Rx8 organisation

This stick uses a 1Rx8 rank configuration, which the listed IdeaCentre platforms accept for single-channel or dual-channel population. Systems that require dual-rank or ECC registered modules cannot use this part.

Questions about this item

How much power does the 1.2V DDR4 module draw when the Lenovo IdeaCentre runs all day?

The module operates at the standard DDR4 voltage of 1.2V, keeping power draw and heat low during continuous use.

What must the Lenovo IdeaCentre 700-25ISH already have for this 288-pin UDIMM to work?

The desktop needs a free DDR4 UDIMM slot that supports 2133MHz non-ECC memory.

Will this CL15 stick run alongside the factory memory in a Y900-34ISZ without manual timing changes?

Yes, it follows JEDEC DDR4-2133 CL15 specs so the system will match timings automatically.
