Buying Guide: important factors of the best motherboard for an i7 8700k

Motherboard size

Knowing the size of the motherboard will help you avoid buying one which is too big for your PC casing. They come in Mini-ITX (M-ITX), Mini ATX (M-ATX), ATX, and Extended ATX (E-ATX) from the smallest to largest.

When it comes to buying, you should choose the largest one which is supported by your PC case as you will have extra slots and a better cooling system. If your system is built for portability, then the M-ITX is a great choice, as it packs all the features but in a smaller size.

The ATX form factor is the most popular motherboard as it offers enough space for slots and ports. However, if you are looking for a more portable M-ITX, the ASUS ROG Strix Z370-I is the perfect choice for you.

CPU compatibility

With a powerful CPU and motherboard, you can achieve higher levels of efficiency due to improved processing power and better cooling options. However, when upgrading your motherboard to suit your processor, or vice versa, you must check the motherboard socket for compatibility with the processor.

The i7 8700k is compatible with 300-series motherboards as they use an LGA1151 socket. 200 series motherboards also use an LGA1151 socket but are not compatible with the i7 8700k.

The Z-series chipset is also more powerful and supports the overclocking capabilities of the i7 8700k, especially in gaming laptops. The B, H, and Q-series chipsets are more attuned for business purposes and will be a waste of power with the i7 8700k processor.

Finally, if you want to compare the Z390 and Z370 chipsets, the Z390 has an inbuilt USB 3.1 and Wi-Fi controller, which makes it a bit more expensive. However, if the added functionalities do not interest you, the Z370 is also just as capable of supporting an i7 8700k. 

The ASUS ROG Maximus XI Hero has a great Z390 chipset, while the Gigabyte Z370 AORUS has a great Z370 chipset.

RAM

The RAM chip’s compatibility with the motherboard is also a vital aspect to consider. RAM is essential for the storage of current memory and ensuring it is easily accessible.

A Z300-series motherboard is capable of supporting both DDR3 and DDR4 sticks. DDR4 memory sticks are preferable as they are more powerful and consume less power than the DDR3.

DIMM (dual in-line memory module) refers to the fast data transfer slots where you insert RAM sticks. There are usually one to eight slots, depending on the size of the motherboard and the quality of the chipset. Four slots are standard for most motherboards, which is more than sufficient for a strong motherboard.

Finally, for gaming computers, 8GB RAM is the minimum requirement for efficient gaming. For those looking to overclock, then 16GB/32GB RAM will do the job.

Most motherboards, such as the Asus ROG Strix Z390-E, have up to 64GB of RAM available with clocking speeds of over 4266 MHz.

Check the PCIe slots

Peripheral Component Interconnect Express (PCIe) refers to the standard interface where you connect high speed components. A great motherboard contains PCle slots where you can add graphics components (GPUs), SSD drives, and Wi-Fi cards.

These slots have different physical configurations which range from x1, x4, x8, and x16 to x32. The number after the x is the number of lanes in that particular slot. An x32 slot has 32 lanes, which means it can only move data at 32 bits per cycle while the x1 can only move at one bit per cycle. The more lanes, the faster the data moves.

PCIe slots allow NVMe connections for SSDs so that data can be read directly from the slot on the motherboard which allows for faster speeds. This means that NVMe drives are faster than other drives which use SATA connections.

The ASUS ROG Maximus XI Hero has a huge variety of PCIe slots.

Built-in Wi-Fi

The advantage of having a built-in wireless chip is that you don’t need to buy one separately when setting up. One major disadvantage is that you cannot detach it if it is faulty or if it is incompatible with your home wireless network.

A 2×2 MU-MIMO 802.11ac Wi-Fi standard is great built-in Wi-Fi. It is available on many motherboards such as the ASUS ROG Maximus XI Hero.

SATA

Serial ATA (Advanced Technology Attachment), or as it is more commonly known, SATA, is an interface which is used to connect hard drives to the motherboard. SATA III is the current industry standard. It also offers fast connection speeds, although not as fast as NVMe connections.

However, the difference in speed is only noticeable when performing large file transfers or complex multimedia editing but not so much with daily activities or gaming.

Most SATA connections for gaming laptops come in M.2 drives. M.2 is not a type of connection like SATA or NVMe, it is just the physical form factor of an SSD. They are usually slim and come with both SATA and NVMe connections.

The Asus ROG Strix Z390-E has a PCIe slot which supports MVMe drives, while the Gigabyte Z370 AORUS has 3 M.2 slots.

What is overclocking?

Overclocking is the process by which you increase your processor’s clock rate to run at a higher speed than that at which it was designed to run. While overclocking increases your computer’s performance, it also produces more heat, and this means that it requires more cooling. Therefore, not all processors can handle overclocking. In fact, most are often locked to prevent you from tinkering with the system.

However, there are CPUs which are sold with overclocking in mind. A CPU with a K in its model number, such as the i7 8700k, is made to withstand all the extra pressure of overclocking.

Conclusion

Choosing the best motherboard for an i7 8700k processor depends on several factors: your level of enthusiasm and how far you are willing to push the limits, level of performance, reliability, and how much you are willing to spend.

Our choice for the best motherboard for an i7 8700k processor goes to the ASUS ROG Maximus XI Hero. It is not only budget-friendly, it is also built with a gamer’s needs in mind. It offers great overclocking and reliability which will indulge your enthusiasm.
