Hi, darkfen! Thanks for your information! According to your TB screenshot, Corsair didn't program DRAM Manufacturer ID for your memory modules. That's why TB displays "Undefined" under "DRAM Components / Manufacturer". Besides, Corsair never programs "DRAM Stepping", "Manufacturing Date", "Module Revision Code" and "Serial Number" what makes it difficult to identify DRAM components. Frankly, Corsair has never paid enough attention to SPD programming. That's why I consider Corsair's SPD poor.
