Buyer’s Guide

The motherboard will hold all the principal components of your computer, so it’s very important that you choose one that meets your PC’s requirements.

Here are factors to consider when buying an X299 motherboard:

1. Overclocking Capacity

One of the primary reasons you would want to change to an X299 motherboard is its overclocking capacity.

To maximize overclocking, you would want a build that has exceptional power delivery and reliable cooling capacity.

Power Supply

Most X299 boards have two CPU power supply connectors that are both eight-pin or a combination of one four-pin and one eight-pin.

Some boards offer optional use of the second connector, so you only need one power connector to run some CPUs at stock speed.

However, if you are spending money on an X299, you should have a premium power supply with two eight-pin connectors to take full advantage of voltage regulation.

Cooling Capacity

Increase the benefits of overclocking with reliable out-of-the-box cooling systems.

Check that your choice of motherboard offers flexible cooling options with its available connectors.

For a no-fuss, easy-install cooler, opt for a large tower cooler or a closed-loop, all-in-one liquid cooler.

Choice of CPU

If you want to hit a specific target with overclocking, keep in mind that your CPU choice matters more than your choice of motherboard.

Whichever X299 motherboard you choose, an i7 7820x CPU with 28 PCI-e lanes should do the trick.

2. Price

Remember: if you spend more, you should get more.

To get the most out of the cost of your motherboard, we suggest you use quad-channel RAM.

It is easier to know the cost of a motherboard than a CPU because the board you choose should reflect the features you need.

A few additional cores on a CPU, for example, can jack up its price by an additional $200.

3. Included Features

You’d also want to check out all the included features on your choice of motherboard to make sure it satisfies all of your requirements.

I/O Connectivity

For a good buy, choose a motherboard that allows high-speed Ethernet networking, preferably one that even supports Wi-Fi.

  • How many USB 3.0 ports do you need? Do you require a Type-C USB connection?
  • Does it have an extra chip for even more ports on it? Do you use Bluetooth?
  • Will the board have a problem connecting over an HDMI connection?
  • Does it have a reliable audio solution?

These are some of the most common questions you would want to be answered when purchasing a motherboard.


Decide how many SATA ports and M.2 PCI-e NVMe slots you need for your build.

You can go the extra mile on your motherboard choice by adding in some adaptor cards that make dual M.2 slots.

For a multi-tasking setup, you might want a motherboard that has more than two video card slots so that you can upgrade or adjust anytime.

Also, decide whether you want multiple options for RGB lighting or a dark, subtle setup.

X299 Motherboard FAQs

1. What is a X299 motherboard?

X299 motherboards are a line of computer main circuit boards that use the X299 chipset.

Think of the chipset as your computer’s central nervous system. It connects the processor, RAM, hard drive, graphics card, and all other components.

The chipset is the main line of communication so that the computer can perform in cohesion.

Manufacturers created the X299 motherboards as a requirement for the Intel Core X-series processors, targeted at HEDT enthusiasts of the Intel lineup.

An X299 motherboard has the LGA 2066 processor socket and 24 PCI Express 3.0 lanes, a big step from the X99’s eight PCI Express 2.0 lanes.

X299 motherboards also support the all-new Intel Optane storage technology, which combines RAM and an SSD.

Depending on the model, X299 motherboards also retain many features of the X99 chipset.

These features include USB 3.0 and 2.0 support, headers and mounting points, overclocking, SATA slots, flexible I/O, M.2 SSDs, and VT-d.

2. Does X299 support Xeon?

X299 chipsets and Xeon processors fall under completely different product lines that use different sockets.

Intel designed the X299 chipset for HEDTs and Xeon processors for workstations.

As such, X299 chipsets and motherboards cannot support Xeon processors.

Xeon processors are workstation CPUs that require the C422 chipset. These CPUs include all Xeon processors under the Skylake-W and Cascade Lake-W series.

3. What is HEDT?

The acronym HEDT stands for high-end desktop, a term coined by Intel that pertains to high-performance desktop computer setups that use the X299 chipset.

HEDT Computing is a large niche that allows excellent computer performance and CPU-intensive tasks.

HEDTs use processors under the Kaby Lake-X, Skylake-X, and Cascade Lake-X series.

Take note, though, that BIOS updates for X299 motherboards discontinued support for Kaby Lake-X processors since October 2019.

4. Which is better x299 vs z370?

Intel offers both the X299 and Z370 chipsets for computer-building enthusiasts.

The X299 chipset uses the LGA 2066 socket for Intel Core X-series processors, ranging from four to 18 cores, and is better for extreme multi-tasking.

On the other hand, the Z370 supports the 8th generation Intel Core processors limited to six cores.

The X299 boards do not have onboard graphics, unlike the Z370 boards, but we still recommend a graphics card.

The Z370 has a maximum of 16 PCI-e lanes, while X299 has more bandwidth for dual graphics with its 44 lanes.

While a Z370 only has 95 watts TDP and maxes out at 64GB RAM, the X299 has 165 watts and can be built with 128GB memory.

Both chipsets won’t go obsolete anytime soon, but the number of X299-supported processors and the number of PCI-e lanes it has makes it more upgradeable.

You can max out both boards with 14 USB ports, but the X299 has two more SATA ports than the Z370, which holds only six.

All of these differences make the X299 the apparent choice for future-proofing and more intensive multi-threaded work applications.

However, the Z370 offers the best value for pure gaming because it does not usually require the multi-core advantage of the X299.

5. How much should I spend on a motherboard?

Different sellers put out the same motherboards at varying prices, and different motherboards vary in cost based on their features.

X299 motherboards can cost as low as $140 and as high as $800, but you don’t have to spend on the high-end options to get the best X299 motherboard.

The most complete and reliable X299 boards out there fall between the $300 and $500 range.

Wrapping Up

If you want an X299 motherboard for gaming or everyday use, go for the ASUS Prime X299-Deluxe II.

It offers many upgrades compared to previous models under the same name, and it provides a direct overclocking experience.

Enjoy using wireless gaming hardware with its high-powered, short-range connectivity.

For a cheaper option, the ASRock X299 Taichi CLX offers the best value for a great price, but you can do with more ports on its rear I/O panel.

If you want to look for motherboards other than the X299, you might want to consider the X470 chipset.
