Lenovo doesn’t manufacture memory. They qualify modules from global tier-one OEMs like Samsung, Micron, and SK Hynix—the same trusted brands behind this module.
JEDEC-compliant and spec-matched for Lenovo systems—ensuring seamless fit, performance, and long-term reliability. All without the Lenovo label—or the premium that comes with it.
