These sticks were pulled from a working system, but they've been fully tested and come with a 12-month warranty, so you're covered.

If your Z420 is feeling sluggish with multiple tasks, this upgrade will give it new life.
Easy plug-and-play install.

Just make sure your motherboard supports registered ECC memory (it does if it's a Z420).

Reliable, tested, and warrantied.
