Use this free Samsung B-Die finder to identify the memory IC behind your DDR4 or DDR5 RAM kit. Search by model number to find Samsung B-Die, Hynix A-Die, Hynix M-Die, Micron and more.

For example, search f5-6400j3239g16gx2-tz5rk → Hynix A-Die.

Kits without a specific die (like "A-Die") are missing due to lack of data. Spotted a mistake or have a kit to add? Tag us on X (@FPSHEAVEN) with your kit ID and its die.
