AMD Socket AM5 Pinout / PINMAP

A detailed diagram of the AM5 socket pinout used in modern AMD Ryzen processors. It shows the location and purpose of the pins (PINMAP), including power, ground, signal lines, and control contacts. The material will be useful for engineers, service centers, overclocking enthusiasts, and motherboard repair specialists.

 

The AMD AM5 pinout diagram helps to correctly diagnose faults, solder and repair damaged tracks, and study the socket architecture. The section contains technical information that ensures the accuracy and convenience of working with electronics.

Main characteristics of the AM5 socket

  • Socket type: LGA 1718 (1718 contacts on the board)
  • Compatibility: Supports AMD Ryzen 7000 and 8000 processors (future series may use the same socket)
  • Memory: Only DDR5 (no DDR4 support)
  • Power consumption: Supports processors with a TDP of up to 170 W
  • Interfaces: Supports PCIe 5.0 for graphics cards and storage devices

AM5 pinout

Unlike PGA sockets (such as AM4), the LGA socket has pins on the motherboard itself. Here are the main groups of contacts that can be found in the AM5 pinout:

  • Power contacts - responsible for supplying voltage to the processor (VCC, VSS)
  • Control contacts - include power management signals, reset and processor enable
  • Memory contacts - connect the processor to DDR5 modules
  • PCIe lines - provide connection to video cards and NVMe drives
  • SMBus and I²C - used to monitor temperature and power consumption
  • USB and other interfaces - responsible for the operation of peripherals, such as USB 4.0 and SATA

Important points during repair and diagnostics

If the motherboard with the AM5 socket does not work, the first thing to pay attention to is the following aspects:

  • Contact condition. Due to the design of LGA 1718, the contacts are very fragile and bend easily. Even one bent contact can cause problems with booting the system.
  • BIOS compatibility. New processors may require a firmware update to work.
  • Power issues. Check all connections, especially the 8+4 pin EPS for CPU power.
  • Overheating. Ryzen 7000 operate at high temperatures, so it is important to install the cooling system correctly.
