Lenovo 16GB DDR4 3200 Kit

This Lenovo-certified desktop memory kit supplies 16GB total capacity across four matching 4GB modules. Each stick is a Samsung-manufactured 288-pin UDIMM running at 3200MHz with standard 1.2V JEDEC timings. The quad-channel arrangement maximises bandwidth for everyday workloads without requiring any BIOS adjustments.

Ideal for standard DDR4 desktop upgrades

The kit suits owners of Lenovo ThinkCentre, IdeaCentre or Legion towers plus any mainstream DDR4 motherboard with four free slots. It will not fit laptops that require SO-DIMM modules, nor servers that demand ECC registered memory. Buyers needing higher per-module density or faster XMP profiles should look elsewhere.

Check motherboard DDR4 slot count and voltage

Verify that your board accepts 288-pin unbuffered non-ECC UDIMMs and can run all four slots at 3200MHz. Confirm the BIOS is set to 1.2V default operation. Ensure the operating system and CPU memory controller support the total 16GB capacity before ordering.

Questions about this item

What motherboard slot does this 288-pin DDR4 kit require?

The modules use the standard 288-pin UDIMM form factor for desktop DDR4, so a desktop motherboard with DDR4 slots is needed.

If I add this 3200 MHz kit to a system that already has slower DDR4 modules, what speed will the memory run at?

All installed DDR4 modules will operate at the speed of the slowest module present, so the faster 3200 MHz sticks will downclock to match the existing memory.

How can I confirm the kit is running at its rated 3200 MHz after installation?

Check the memory speed in the BIOS or with a system-information tool such as CPU-Z; it should report 3200 MHz (PC4-25600) at the standard 1.2 V.
