How To Choose The Best Compatible LGA 1155 CPU?

Socket Connectivity

Your CPU is connected to your motherboard by a socket. To ensure that the motherboard and CPU are compatible, you must check the compatibility. They are not only physically connected but also electrically. It should be easy for the CPU to connect to the motherboard socket, as the compatibility should be based on that.


The short form of gigahertz is GHz. Your CPU’s speed is determined by its frequency. GHz is measured in cycles per second. You should find a processor with more cycles per second, making your gaming experience more efficient.


The cache is a term used to describe the memory of your processor. For temporary storage, the cache serves as faster memory. Caches are usually small, so if you get an enormous cache, you’ll be able to recover large amounts of information faster. In the gaming world, data recovery is essential.

Thermal Scheme Power

You can interpret the amount of heat your CPU generates using the Thermal Scheme Power feature. So, if you want your processor to perform well, protect it from overheating. You can buy CPU coolers for your CPU too.


The best LGA 1155 CPU installed on your computer system will make it much more enjoyable. Additionally, you will also be able to run CPU-hogging applications and games without experiencing any lag. Furthermore, such an upgrade will increase your productivity and decrease your time spent completing tasks.

Frequently Asked Questions

What is the Difference Between Socket 1150 and 1155?

The LGA 1150 is a successor of the 1155 socket. The 1150 socket supports the new fourth and fifth-generation Intel processors, while the 1155 socket was built for the second and third-generation Intel chips. The 1150 socket is based on the Haswell microarchitecture, and the 1155 socket is based on the Ivy Bridge microarchitecture.

LGA 1155 supports DDR4?

The LGA 1155 motherboards cannot support DDR4 memory because when they were produced, DDR3 was the newest version available, and that’s what they support

Will an LGA 1155 Fit 1151?

That won’t work because each socket has a different number of pins and a different function. So, You may end up damaging the CPU if you use a different socket with a different processor.

Is LGA 1155 outdated?

Nope. It isn’t outdated. However, if you can, I recommend upgrading to the 7th generation Kaby Lake processors without changing the motherboard.

What GPU is compatible with LGA 1155?

A powerful GPU will be slowed down if your motherboard (being 1155) only supports Intel CPUs up to Gen 3. If The 1050/1050 Ti, as well as the RX 460 would be excellent choices if you are looking for a GPU that will be both powerful and affordable.
