ASRock Z390 Phantom Gaming-ITX/ac Review: ITX Excellence

Editor's Choice

How We Test

The second Mini ITX board we’ve tested using the Core i9-9900K, ASRock’s Z390 Phantom Gaming-ITX/ac goes up directly against Supermicro’s C9Z390-CG-IW. Full ATX models we included in our comparison give the tiny boards some big competition while helping to fill out the charts.

SoundIntegrated HD audio
NetworkIntegrated gigabit networking
Graphics DriverGeForce 399.24

The same platform that cooled the 10 cores of our Core i9-7900X worked equally well with the eight cores of the Core i9-9900K, as we’ll show in the overclocking evaluation on the next page.

    It'd be nice to see some followup with asrock regarding the dram over voltage...

    "Everyone" does it, this time it was more egregious than the typical 15-25mV. I'm currently writing up a board that's only 7mV over. Seven. That's incredibly closer to spec than most competing products. Heck, I might just give the new board kudos for ONLY being 7mV over-spec.

    Why tom's hardware modifies pictures of reviews with extreme contrast. I can't see under the heatsink fins. Its totally useless, people are coming here to decide, not look at flashy eyecandy.

    The images match the profile of my monitor. Maybe I should be using a different monitor?

    Thunderbolt port is not working at full speed? 40Gb/s ? Why is running at half (20Gb/s) ?

    Because it's using a cheaper PCIe x2 controller.
