In this video, I build a DIY DDR5 SPD reader/writer based on the SPD RW project using an Arduino Nano and a custom PCB that I designed from scratch. After assembling and testing the programmer, I use it to communicate with the DDR5 module and begin diagnosing the fault. What started as a simple SPD investigation quickly turned into something much more interesting. After closer inspection, I discovered that one of the BGA memory chips had partially separated from the PCB, causing the module to fail. In this video: ✔ Designing a custom DDR5 SPD programmer PCB ✔ Building the programmer with an Arduino Nano ✔ Reading DDR5 SPD data ✔ Diagnosing a faulty DDR5 RAM module ✔ Microscopic inspection of the memory chips ✔ Discovering the real hardware failure The repair isn't finished yet! In Part 2, I'll remove the memory chips, inspect the solder joints, perform a full BGA reball, and find out whether this DDR5 stick can be brought back to life.
