What Socket Type Is Soldered To The Motherboard, Along With The CPU

Share If You Find This Post Helpful!

When it comes to building or upgrading a computer, understanding the various components and their compatibility is crucial. One of the most important components is the central processing unit (CPU), which is responsible for executing instructions and performing calculations. The CPU needs to be connected to the motherboard through a socket type. In this article, we will explore the socket type that is soldered to the motherboard, along with the CPU, and delve into the reasons why it is an essential consideration for computer enthusiasts and professionals alike.

What is a Socket Type?

A socket type is a physical interface on the motherboard that allows the CPU to connect and communicate with the rest of the system. It provides both the mechanical support and electrical connections necessary for the CPU to function properly.

The Importance of Socket Types

The socket type is essential because it determines the compatibility between the CPU and the motherboard. Each CPU is designed to fit a specific socket type, and attempting to install a CPU with an incompatible socket can result in damage to the CPU or motherboard. Therefore, understanding the socket type is crucial when selecting a CPU or planning an upgrade.

Common Socket Types

LGA Socket Types

LGA (Land Grid Array) socket types are commonly used in modern desktop computers. The CPU pins are located on the socket, while the motherboard has corresponding contact points. Some popular LGA socket types include:

  • H1: LGA 1151
  • H1: LGA 1200

PGA Socket Types

PGA (Pin Grid Array) socket types are found in older CPU designs and some server-grade processors. With PGA, the pins are located on the CPU, and the socket contains holes that match the pin configuration. Examples of PGA socket types include:

  • H2: PGA 988
  • H2: PGA AM4

BGA Socket Types

BGA (Ball Grid Array) socket types are typically used in small form factor devices such as laptops and compact PCs. In BGA sockets, the CPU is directly soldered onto the motherboard, eliminating the need for pins and sockets. BGA socket types are not user-upgradable. Examples include:

  • H2: BGA 1168
  • H2: BGA 1526

The Soldering Process

When a CPU has a soldered socket type, it means that the CPU is permanently attached to the motherboard through a soldering process. Soldering involves heating the solder to a liquid state, attaching the CPU to the motherboard, and allowing the solder to solidify, creating a permanent bond.

Advantages and Disadvantages of Soldered Socket Types


  • Enhanced durability and stability due to the permanent connection.
  • Reduced electrical resistance, which can lead to improved performance.
  • Space-saving design, making it suitable for compact devices.


  • Limited upgradability as the CPU cannot be easily replaced.
  • Higher cost for motherboard replacements if the CPU fails or needs an upgrade.
  • Lack of flexibility in choosing different CPU models.

Compatibility Considerations

When selecting a CPU, it is crucial to ensure compatibility with the motherboard’s socket type. Manufacturers typically provide compatibility lists or specifications that indicate which CPUs are compatible with each socket type. Checking these lists can help avoid any compatibility issues.

Upgrading a CPU with a Soldered Socket Type

Upgrading a CPU with a soldered socket type can be challenging. In most cases, upgrading requires replacing the entire motherboard. It is important to consider the potential cost and compatibility issues before attempting an upgrade.

Future Trends and Socket Types

The technology landscape is constantly evolving, and new socket types may emerge in the future. It is expected that future socket types will continue to focus on improving performance, power efficiency, and compatibility with new CPU architectures.


The socket type that is soldered to the motherboard, along with the CPU, is a critical factor to consider when building or upgrading a computer. Understanding the different socket types and their implications can help ensure compatibility and prevent potential issues. Whether it’s an LGA, PGA, or BGA socket, each type has its advantages and disadvantages, which must be carefully evaluated based on the specific needs of the user.
