Compatible Lenovo ThinkCentre Models

This 32GB DDR4 SODIMM is validated for Lenovo ThinkCentre M70a G3, M70q, M90q and M90s G2 systems. It replaces Lenovo part numbers such as 5M30Z71652 and 4X71A11993. Buyers needing ECC or registered memory cannot use this module.

260-Pin SO-DIMM Form Factor

The stick fits the standard 260-pin DDR4 SO-DIMM slots found in the listed ThinkCentre units. It is unbuffered, non-ECC and dual-rank 2Rx8. Systems requiring a different pin count, voltage or rank configuration will not accept this upgrade.

JEDEC 1.2V Operation

Running at the JEDEC-standard 1.2V, the module draws minimal power and generates little heat without a spreader. CL22 latency at 3200MHz delivers stable performance for everyday workloads. Builds that demand lower latency or higher voltage profiles should look elsewhere.

Questions about this item

Does the 32GB DDR4 3200MHz CL22 module hit a thermal limit during sustained workloads?

The module has no heat spreader and runs at standard 1.2V JEDEC voltage, so it relies on the chassis airflow of the ThinkCentre M70a G3 M70q M90q M90s G2 to stay within operating temperature.

How much power and noise does the 1.2V 260-pin SODIMM add when the system runs all day?

At 1.2V the DDR4 module draws minimal power and produces no audible noise; total system thermals and acoustics remain dictated by the Lenovo platform cooling design.

Which slot and platform must already be present for this 2Rx8 32GB SODIMM to work?

A free 260-pin DDR4 SODIMM slot in a Lenovo ThinkCentre M70a G3 M70q M90q or M90s G2 is required; the module is non-ECC unbuffered and matches the OEM part numbers listed.
