How to Read DDR4 RAM Model Numbers of Different Memory Brands

When comparing RAM (Random Access Memory) modules or verifying your motherboard's Memory QVL (Qualified Vendors List), you may have come across hard-to-figure-out product codes, such as "HX430C15SB2/8" or "TED416G2133C1501" or "AVD4U24001608G-4M" or "BLS8G4D240FSA".


If you are wondering what these letters/numbers mean and how to read/interpret it, I have made a quick guide below to help you familiarize and understand the meaning behind the nomenclature of such RAM product codes.

Note: As of this date, I have only posted DDR4 Desktop RAMs from Avexir, Corsair, GeIL, G.Skill, Hyper X, Patriot, and Team. More to follow when time permits me to compile other RAM models.
