LGA 1151: Everything you need to know

LGA 1151 is a land grid array socket that was launched in 2015. It has superseded LGA 1150 and is used on Intel’s CPUs.

The main difference between the two sockets is the number of pins – LGA 1151 has more than LGA 1150. Generally, chipsets with more pins provide more support for overclocking and higher speeds.

LGA 1151 was designed to replace the aging LGA 1150 socket while also offering improvements over it. The additional pins on LGA 1151 offer increased stability and support for higher clock speeds, making it an ideal choice for gamers and power users who want to get the most out of their CPUs.

If you’re looking to upgrade your old CPU or build a new gaming rig, LGA 1151 is the way to go. In this article, we’ll cover everything you need to know about LGA 1151 including its key features, supported CPUs, and motherboards.

LGA 1151 – what is it?

LGA 1151, also known as Socket H4, is an Intel microprocessor-compatible socket that comes in two versions: a Land Grid Array (LGA) and a Pin Grid Array (PGA).

The former is used for Skylake and Kaby Lake CPUs while the latter is used for Coffee Lake CPUs. LGA 1151 has 1151 protruding pins that make contact with the pads on a CPU.

The benefits of LGA 1151

The main benefit of LGA 1151 is that it supports both DDR3 and DDR4 memory, which means that you can use either type of memory with your LGA 1151 motherboard. Additionally, LGA 1151 CPUs are compatible with a wide range of motherboards from different manufacturers.

The history of LGA 1151


LGA 1151 was first introduced in 2015 with Intel’s sixth-generation Skylake processors. It replaced the older LGA 1150 socket, which was used for fourth- and fifth-generation Intel Core processors.

In 2017, Intel released eighth-generation CPUs based on the Coffee Lake microarchitecture, which uses the new LGA 1151 v2 socket.

How to install an LGA 1151 CPU

Installing an LGA 1151 CPU is a relatively simple process.

  • First, you’ll need to remove the existing CPU from the socket.
  • Then, clean the socket by removing any dust or debris.
  • Next, line up the notches on the CPU with the corresponding notches in the socket, and carefully insert the CPU into the socket.
  • Finally, secure the CPU in place by locking the lever at the top of the socket.

Compatible GPUs for LGA 1151

Almost any modern GPU will be compatible with an LGA 1151 motherboard. However, if you’re looking for optimal performance, you’ll want to choose a GPU that’s specifically designed for use with an LGA 1151 motherboard.

For example, Nvidia’s GeForce GTX 1080 Ti is a good choice for gamers who want top-of-the-line performance.

Overclocking on LGA 1151

Overclocking is the process of pushing a CPU beyond its stock speed in order to boost performance. While overclocking can void your CPU’s warranty, it’s generally safe to do if you know what you’re doing.

If you’re interested in overclocking your LGA 1151 CPU, there are a few things you’ll need to keep in mind. First, you’ll need to choose a suitable motherboard and CPU cooler.

A CPU, or Central Processing Unit, is the brain of your computer. It handles all the instructions your computer receives and sends out.

CPUs come in many different shapes and sizes, but they all have the same basic function. Choosing the right CPU for your needs can be tricky, but we hope this article has helped demystify the process a bit.

LGA 1151 is a land grid array socket that was released in 2015. It supports 6th to 9th-generation Intel processors on the LGA 1151 platform.

Frequently Asked Questions

What RAM does LGA 1151 support?

LGA 1151 supports 6th generation Intel Core i7/ i5/ i3/ Pentium/ Celeron processors.

The power phase design helps to support Intel Turbo Boost 2.0 technology. Additionally, 4x DDR4-2133 DIMM slots are available for a maximum capacity of 64GB.

What is the strongest CPU in 2022?

The Core i5-13600K is Intel’s best all-around CPU as of 2022. It offers great performance for gaming and other purposes and is a significant upgrade over its predecessor.

The only downside is that it is slightly more expensive than some of the other options on the market.

What generation does LGA 1151 support?

LGA 1151 supports 9th and 8th Generation Intel Core Desktop Processors. LGA 1150 was succeeded by the LGA 1151 in 2016, which was designed to replace it in generation ninth of Intel’s CPUs (Coffee Lake).

The main difference between the two is that LGA 1151 has more pins – 1,151 vs. 1,150 – which allows for more data transfer lanes and thus increased bandwidth.

Additionally, LGA 1151 can support both DDR4 and DDR3L memory, while LGA 1150 is limited to DDR3 only.

What is the strongest LGA 1151 CPU?
