When building or upgrading a PC, choosing the right processor is crucial, and understanding the compatibility with your motherboard is key.
The LGA 1151 socket supports Intel processors like Skylake (6th gen) and Kaby Lake (7th gen), including models like the Core i7-7700K. It is compatible with a variety of Intel desktop CPUs.
In this article, we’ll explore the different Intel processors that use the LGA 1151 socket, their features, and how to choose the best one for your setup.
Understanding LGA 1151 Socket
1. What is LGA 1151?
LGA 1151 stands for Land Grid Array 1151, which means it has 1,151 contact pins on the motherboard to connect with the CPU.
Intel created this socket to support multiple generations of processors. It replaced the older LGA 1150 socket and was later replaced by the LGA 1200.
Some LGA 1151 motherboards support only 6th and 7th Gen CPUs, while others support 8th and 9th Gen CPUs. Make sure to check your motherboard chipset before choosing a processor.
2. Key Differences Between LGA 1151 Versions
- Two Versions Exist – LGA 1151 has two different versions that do not work with each other.
