Am4 Pinout Diagram _verified_ Jun 2026
Limitations and caution
Because AM4 uses a PGA design, it is incredibly easy to accidentally bend pins during thermal paste changes or if the CPU is dropped. If you pull your cooler off and find a cluster of warped pins, follow this precise repair method. Required Tools:
Sometimes, specific pins related to power delivery can show signs of scorching if there’s a major voltage issue or socket failure.
Complete the electrical circuits and provide grounding for shielding.
When using an Accelerated Processing Unit (APU) with integrated Radeon graphics, specific pins change their functional roles to output video signals.
An AM4 pinout diagram reveals that the pins are categorized into several critical functional groups. If you are inspecting a processor for bent pins, knowing which zone is affected can help you predict if the chip will still function or which specific feature (like a RAM slot) might fail.
These connect your CPU directly to your GPU and NVMe drives.
