What Should I Look for When Buying an LGA 1155 CPU? 

For you to settle on the best LGA 1155 CPU, you will need to take a look at the following:

Socket Connectivity

The socket connects the CPU and your motherboard. You need to check the compatibility of the CPU and motherboard. Their connection is not only physical but also electrical. The compatibility should be in such a way that the CPU is easy to connect with the motherboard socket.

Speed

Gigahertz is recorded as GHz in the short form. It’s the frequency that determines the speed of your CPU. GHz operates in the form of the frequency of cycles per second. Try to find a faster processor with more of these cycles per second that will make your gaming experience efficient.

Cache

Your processor’s memory is also known as a cache. The cache is a quicker memory used for temporary storage. The Cache is often small. If you get a bigger cache, you can be sure of the faster recovery of large data that you’re able to store. Recovery of data is essential in the gaming world.

Thermal Scheme Power 

You can use the Thermal Scheme Power feature to interpret the amount of heat your CPU produces. Always protect your processor from overheating if you want it to serve you well.

Processors have coolers but if yours comes with none, you will need to get one.

FCLGA1155 is the same thing as LGA 1155. The FCLGA 1155  can support several processors in the Intel Core i7, i5, and i3 Desktop Processor Series.

These processors also support Intel Pentium in the G8, G6, and G2 Desktop Processor Series. When it comes to Intel Celeron, it supports  G5, G4, and G16 Processor Series.

LGA 1151 vs 1155

Similarities 

Both CPUs require the use of multiple pins for compatibility with motherboards. LGA 1151 has 1151 pins to create contact with the motherboard.  LGA 1155 requires 1155 pins to achieve compatibility.

Differences 

1151 supports the memory storage of DDR4, DDR3, and DDR3L while the LGA supports the memory storage of DDR3.

The LGA 1151 is ideal if you’re looking for excellent CPU response and providing a good connection. The LGA 1155 is what you need as a gamer to enable you to experience immersive games.

LGA 1155 CPU Installation

The following is a step by step guide on how to install an LGA 1155:

  1. Find the golden triangle in your CPU and align it with the little triangle on the plastic cover. You can align it with the metal triangle found inside the CPU socket.

  2. Push the retention lever down. Pull it down to loosen itself. It will open the socket.

  3. Place the CPU into the socket and ensure it’s fitted.

  4. Lower the retention arm. If you feel some resistance, push it down a bit harder. 

  5. Return the pushpin-styled heatsink by ensuring the plastic pins fit in the four holes.

  6. Ensure you have enough slacks on the CPU fan wire to reach the CPU fan header on your motherboard.

  7. Apply force on all corners of the heatsink using both hands at the same time to ensure it’s stuck.

  8. To know if your installation was successful, listen to the distinctive click by rotating the heatsink.

  9. You can confirm successful installation by flipping over the board to ensure the black plastic sticks out as far as the white plastic. Tighten it if that’s the case.

  10. Twist the fan wires to avoid contact with your fan. Tuck them into the labeled CPU header on the motherboard.

You can check out the video below for a detailed overview of the above guide.
