ASRock Z370 Extreme 4 Motherboard Review

ASRock Z370 Extreme 4

Have you checked out our reviews of the new 8th Generation Intel Core i5-8400 and the i7-8700K? If that’s a CPU you want in your next system build, then you’ll be needing the new Z370 motherboards! Today we’ve got the latest ASRock Extreme 4 motherboard, which comes packed full of features that are sure to appeal to system builders and PC gamers alike.

Featuring a durable design that implements a 12 Power Phase Digital PWM design, robust motherboard cooling and more, the Extreme 4 promises to be a powerhouse for the new Intel CPUs. Allowing for high overclocks and improved stability on your memory, PCIe devices, and the CPU. Even better, it looks set to do so without breaking the bank.

“The improved power phase design offers smooth power delivery to the more powerful 8th Generation Intel® Core™ Processors, providing unmatched overclocking capabilities, lower temperature for advanced gamers, and reinforced system stability for taking on all sorts of arduous computing tasks.” – ASRock

If high-end overclocking isn’t all you’re after, you’ll also find room for multiple graphics card, exceptional onboard audio thanks to Realtek and DTS Connect, a huge amount of storage options including M.2 and Optane, as well as Gigabit LAN. Oh, and it has RGB lighting, but show me something that doesn’t these days; love it or hate it, it’s here to stay.

    Cool review! Looking forward to replace my old rig with new 8700k cpu for my wedding photography / videography editing.
    Now, became more difficult to choose MB. Apparently there are big difference in speed.

  2. Alex says:

    Sounds I found MB to buy. Looking forward to replace my old rig with new 8700k cpu for my wedding photography / videography editing.
    Still it is not clear why results have such a big difference if they use same CPU and Z370 chip.

  3. Zeke says:

    Did you leave MCE enabled for those benchmarks? It really screws with the scores, and is likely why the ASUS boards are ahead. They are basically auto-overclocked on the stock benchmarks, making it not truly the same scenario. To make it even, you could have just enabled or disabled MCE on every board.

  4. Gareth says:

    What I want to know is if the Creative Cinema3 sound on the Fatal1ty is any better than the sound on the Extreme4 or not. Since they use the same codec surely it’s just a software add?

    Also neither board has onboard wifi whereas the Taichi has dual band wifi.

    I decided I want an asrock board but which one.

  5. Gareth says:

    Also the Fatal1ty and Taichi have debug and reset switches where the extreme4 does not

  6. Donald says:

    Does this motherboard have good overclocking abilities? If yes, then it’s probably the best motherboard you can get in terms of value tbh.
