Compatible Lenovo IdeaCentre Desktops

This 16GB DDR4 module is built for the Lenovo IdeaCentre 510A and 720 towers listed in the compatibility data. It targets owners of those specific systems who want a straightforward memory upgrade.

Suitable for JEDEC DDR4 2666 Non-ECC Slots

The stick suits builders upgrading the named Lenovo desktops with a standard unbuffered DDR4 slot. It does not suit buyers who need ECC error correction or registered modules for workstation or server boards.

16GB Density Decides Fit

Each module provides 16GB in a single 2Rx8 rank at 1.2V. If the target Lenovo model accepts this density per slot the upgrade works; otherwise a different capacity must be chosen.

Questions about this item

Will the 288-pin DDR4 UDIMM fit the memory slots in my Lenovo IdeaCentre 510A-15ARR?

Yes, this 288-pin DDR4 UDIMM matches the desktop DIMM slots used by the IdeaCentre 510A-15ARR and the other listed 510A and 720 models.

What is the correct way to seat the module, and what step do people often miss?

Align the notch with the slot key, press straight down until both side clips click, and verify the module sits flush — the step most missed is not pressing firmly enough for the clips to engage.

Does this 16GB CL19 1.2V module need any firmware updates or heat spreaders added later?

No firmware is required; the JEDEC-standard DDR4 2666 module runs at 1.2V without a heat spreader and is backed by a limited lifetime warranty.
