ASRock X299 Extreme4 ATX Motherboard Review: Making Core-X Affordable?

Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

How We Test

Additional cores create additional thermal and power loads that can push other hardware to its limits, yet the parts we’re hoping to push to the limit are all on the motherboards. Intel’s 10-core, 20-thread Core i9-7900X CPU is a great product for stressing the voltage regulators of various X299 motherboards, particularly under our full-AVX-load overclocking stability test.

The tremendous heat produced by the Core i9-7900X required us to use nothing less than our award-winning Fractal Design S24 liquid cooler system sample. Getting its fans to blow sufficiently over each motherboard’s voltage regulator required additional design consideration: Of our leftover case review samples, Cooler Master’s HAF-XB had the best layout.

Comparison Products

Close price matches to the X299M Gaming Pro Carbon AC include ASRock's X299 Taichi, Gigabyte's X299 Aorus Gaming 3, and Asus' Prime X299-A. We've added MSI's X299 Gaming Pro Carbon AC and ASRock's X299E-ITX/ac for a more-entertaining ATX-to-MicroATX-to-Mini-ITX comparison

    I would have liked to see the performance available through the chipset M.2 slot. or maybe a comparison with both storage setups.

    I don't think many people will choose a $100 cheaper board and then add a $100 storage adapter.

    They may use a $15 m.2 to PCIe adapter.

    Umm, it says $32.99 on Newegg. The link sends me to a cooler. Fix that? Or is it just me.

    Tom, was a VROC key required when using the ASRock Ultra Quad M.2 card?

    VROC key is always required, and only required, when using "software" RAID for the CPU-integrated PCIe controller. I think of it as RAID firmware module for the CPU, rather than the chipset.
