  • NVMe on top of the motherboard (important for cases like InWin Chopin)

  • Good audio even on front panel header

  • Wifi extremely stable and fast


  • Stock "Auto" settings for CPU and SOC massively overvolt, generating extra heat and power fluctuations

  • SOC VRM buzzes whenever iGPU is under load, gets louder when overclocked

  • Moderate SOC voltage (1.175) leads to VRM temps in the 90C range, causing power draw to increase

  • Flashing motherboard with Gigabyte @BIOS utility bricked board, requiring replacement

  • 8-pin CPU power socket in an awful location, making it difficult to unplug without pulling out the whole board

Other Thoughts: Note: This review is based on having two of this board, both exhibiting all of the same issues.

If you're planning on using this for a CPU-only build, you'll probably be fine. But I would not suggest putting an APU on this board, especially if you plan on overclocking it, until Gigabyte either revises the board or fixes the voltage control issues with a BIOS update. My 2400G APU pulls over 120W on stock motherboard settings during Cinebench and Blender testing, immediately causing the CPU to throttle even with aftermarket cooling. Core voltage was measured at over 1.4V, which is an insane amount of voltage considering stock voltage is 1.225!!! The GPU/SOC voltages suffered similar problems, with stock settings causing offsets of +.05-.1 volts (which is a lot considering recommended SOC range is 1.05-1.2). With a 150W 80+ PSU, adjusting the GPU clocks at all would cause over-voltage protection to trip on the PSU, causing an immediate shutdown. This is unacceptable and is probably the poorest stock voltage regulation I've seen across multiple AM4 mITX boards from ASrock, Asus and Gigabyte.

VRM cooling is also rather poor. Doing GPU only overclocking, I had to limit myself to 1.2V SOC voltage to keep VRM temps below 100C during extended load. Certainly part of this is due to my case being very small, but I ensured that the VRMs had plenty of intake and exhaust airflow to prevent recirculation. This heat and voltage limitation meant that instead of getting 1650MHz on my GPU (tested on a different board to be stable at 1.25V), I had to come all the way down to 1550MHz @ 1.175 for long-term stability. That's a lot of performance left on the table because of insufficient surface area for VRM cooling.

The last annoyance is more of a pet-peeve, but still worth mentioning. When the GPU is being used, the SOC VRMs create a buzzing noise that changes frequency based on framerate, and volume depending on SOC voltage. It's definitely audible outside of the case with the cover on. The noise is evident everywhere the GPU is used, from the Windows 10 start menu (audible click on every single scroll) to synthetic and gaming benchmarks (Fire Strike combined test produces a slow, loud clicking noise @ 6 FPS, Crysis benchmark produces a constant grinding noise @ 60+ FPS).

Great looking, clean silver-black itx board. Board LEDs are non-addressable. Needs 2 more fan headers rather than LED headers. 4+2 phase. No VRM issues yet. For a b450 board, this is more than enough. This is the body of the Ryzen Silver Mini-monster.

Good WIFI for the price. Plus I like Aorus.

I previously gave this board 4 stars, but it definitely does not deserve it. When all cores are at use (1.2+ volts), the VRMs make a horrible grinding noise. It gets louder and louder the more intensive the task. I guess I just didn't notice it with the loud stock cooler, but now that I have a nicer one it is unmistakable. Sometimes I can hear it on video games, but when I use OBS that sucker GRINDS. The temps of the VRMs have never exceeded 70C yet, but the noise is just awful. I'm not even overclocking! The BIOS layout is just bad. There is no clear option to overclock memory, which I was planning on doing. Gigabyte's suite of apps look like they were made in 2003. RGB Fusion is not very customizable. The only reason it doesn't get 1 star is because it hasn't caught on fire. Gigabyte has really mucked up the bed on it's AM4 boards. If you are buying an ITX board, go ASRock or MSi. I really wish I had.

Best ITX motherboard. Easy to work with BIOS.
