8 GB DDR4 UDIMM for Lenovo IdeaCentre

This 8 GB DDR4 2666 MHz CL19 module is built for Lenovo IdeaCentre 510A and 720-18 desktops. It runs at 1.2 V as an unbuffered non‑ECC UDIMM and meets JEDEC PC4‑21300 specifications. The single 1Rx8 rank installs in a standard 288‑pin slot without a heat spreader.

The module suits owners of the exact IdeaCentre 510A‑15ARR, 510A‑15ICB, 510A‑15ICK, 720‑18APR and 720‑18IKL models needing an 8 GB upgrade. It does not suit builders using other motherboards, laptops, servers requiring ECC or registered memory, or systems limited to lower DDR4 speeds.

2666 MHz CL19 DDR4 speed rating

The decisive spec is the DDR4 2666 MHz CL19 rating (PC4‑21300). If the target board accepts this speed and timing the module will operate at its rated frequency; otherwise it will down‑clock to 2400 MHz or 2133 MHz per the backward‑compatibility data.

Questions about this item

Does the 1.2V CL19 module run cool and quiet inside a Lenovo IdeaCentre 510A all day?

Yes. The stick operates at 1.2 V with no heat spreader, drawing minimal power and producing no fan noise of its own.

My IdeaCentre 720-18 has four DDR4 slots — do I need any special tools or paired sticks to add this 8 GB UDIMM?

No tools are required. The 288-pin unbuffered DIMM installs by hand and works as a single 1Rx8 module; matching pairs are not mandatory.

Will this 2666 MHz stick downclock properly if my 510A-15ICB currently runs 2133 MHz memory?

Yes. The module is backward compatible with 2133 MHz and 2400 MHz systems and will automatically run at the lower speed.
