ThinkCentre M80q M90a M90q upgrade

This 32GB DDR5 SODIMM is built for Lenovo ThinkCentre M80q Gen 3, M90a Pro Gen 3 and M90q Gen 3 desktops. It replaces Lenovo part 4X71K20070 and installs as a single module in the available SO-DIMM slot. Buyers who need ECC error correction or registered buffering must choose a different module.

DDR5 4800 CL40 1.1V limits

The module runs at JEDEC-standard DDR5 4800 with CL40 latency and 1.1V voltage. Systems that only support lower DDR5 speeds will down-clock the part, while platforms requiring higher data rates or different voltages cannot use it.

2Rx8 262-pin non-ECC SODIMM

The dual-rank 2Rx8 organisation on a 262-pin unbuffered non-ECC stick is the single specification that decides fit. Only ThinkCentre models listed above accept this exact rank, pin count and ECC configuration.

Questions about this item

Should I pick the 32 GB module or add two smaller sticks for my ThinkCentre M90q Gen 3?

This is a single 32 GB DDR5 4800 CL40 SODIMM; if your system has only one slot or you want maximum capacity per slot, this module fills it in one step.

What does the 4800 MT/s rating deliver once installed in a Lenovo ThinkCentre M80q Gen 3?

The module runs at JEDEC-standard DDR5 4800 with CL40 latency at 1.1 V, giving the rated bandwidth and timing the platform expects without overclocking.

Is the 262-pin DDR5 SODIMM interface compatible with the memory slot in my M90a Pro Gen 3?

Yes — the 262-pin DDR5 SODIMM form factor matches the slot used in the listed ThinkCentre models, and the module is unbuffered non-ECC as required.
