Lenovo V55t Gen 2-13ACN memory upgrade

This 8GB DDR4 module is built specifically for the Lenovo V55t Gen 2-13ACN desktop. It targets owners who want a straightforward capacity increase without compatibility guesswork. The JEDEC-standard specification ensures the system recognises the DIMM at its rated 3200MHz speed. Buyers needing ECC error correction or registered buffering should look elsewhere.

288-pin UDIMM form factor and 1.2V operation

The unbuffered 288-pin layout fits standard DDR4 desktop slots on the V55t motherboard. Operating at 1.2V, the module draws the same voltage as the factory memory, so no BIOS voltage adjustments are required. No heat spreader is fitted, keeping the profile low for tight chassis clearances. Systems that demand registered DIMMs or higher voltage kits cannot use this part.

Backward compatibility down to 2133MHz

The module automatically negotiates lower speeds — 2933MHz, 2666MHz, 2400MHz or 2133MHz — when installed alongside slower memory or in older boards. This flexibility means a single stick can serve mixed-speed configurations without manual tuning. ROHS compliance and JEDEC certification keep the upgrade warranty-safe for the host system. No software bundle or installation tool is included in the package.

Questions about this item

Does the DDR4 3200MHz interface downclock if my Lenovo V55t Gen 2-13ACN only supports 2666MHz?

Yes. The module is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz systems and will run at the highest speed the platform allows.

Will this 288-pin UDIMM fit the DIMM slots on a Lenovo V55t Gen 2-13ACN?

Yes. It is a standard 288-pin unbuffered non-ECC UDIMM designed specifically for that desktop model.

What is the correct way to seat the module so the motherboard recognises the full 8GB?

Align the notch with the slot key, press straight down until both retention clips click into place, then verify 8GB appears in BIOS or the OS.
