The world of computer hardware can be complex and overwhelming, especially when it comes to ensuring compatibility between different components. One of the most critical aspects of building or upgrading a computer is the CPU socket, which must match the processor you intend to use. Two popular socket types from Intel are LGA 1155 and LGA 1151, each designed for specific generations of CPUs. If you’re wondering whether an LGA 1155 CPU will fit into an LGA 1151 socket, this article is designed to provide you with a detailed understanding of the differences and compatibility issues between these two socket types.
Introduction to LGA Sockets
LGA stands for Land Grid Array, a type of socket used for Intel CPUs. Unlike PGA (Pin Grid Array) sockets where the pins are on the CPU itself, LGA sockets have the pins on the motherboard, and the CPU has contact points that match up with these pins. This design helps in reducing the risk of damaging the CPU pins during installation. Both LGA 1155 and LGA 1151 sockets are part of Intel’s lineup for desktop processors, but they were introduced for different generations of CPUs.
LGA 1155 Socket
The LGA 1155 socket was introduced by Intel in 2011, alongside the 2nd generation Core processors (Sandy Bridge). This socket supported a wide range of processors, including Core i3, i5, and i7 models from the 2nd and 3rd generations. The LGA 1155 socket has 1155 pins and is designed to work with processors that have a thermal design power (TDP) of up to 95 watts. It was a significant improvement over its predecessors, offering better performance and power efficiency.
LGA 1151 Socket
The LGA 1151 socket, on the other hand, was introduced in 2015 with the 6th generation Core processors (Skylake). This socket has also been used for subsequent generations, including Kaby Lake and Coffee Lake processors. Like the LGA 1155, the LGA 1151 has 1151 pins, but it is not backward compatible with older CPUs due to changes in the socket’s keying and the power delivery system. The LGA 1151 socket supports a broader range of TDPs, from 35 watts to 95 watts, making it versatile for different applications, from compact builds to high-performance gaming rigs.
Compatibility Between LGA 1155 and LGA 1151
The question of whether an LGA 1155 CPU will fit into an LGA 1151 socket is straightforward: no, it will not fit. The primary reason for this incompatibility is not just the difference in the number of pins (which is minimal), but rather the changes in the socket’s design and keying. The keying mechanism is a small notch or protrusion on the CPU and the socket that ensures the CPU is installed correctly and prevents it from being inserted in the wrong orientation. The keying for LGA 1155 and LGA 1151 sockets is different, making it physically impossible to install an LGA 1155 CPU into an LGA 1151 socket.
Reasons for Incompatibility
Several reasons contribute to the incompatibility between LGA 1155 CPUs and LGA 1151 sockets:
