Gigabyte X399 Aorus Xtreme review: A crazy motherboard for a crazy processor

By Koh Wanzi - 7 Oct 2018
Launch SRP: S$635

Temperature, power consumption & overclocking

Temperature, power consumption and overclocking



We measured the temperatures of the VRM and PCH heatsinks after running 40 loops of the 3DMark Fire Strike Stress Test. You’ll naturally want lower temperatures since it shows that the respective heatsinks are doing a more effective job of dissipating heat.


Power consumption

To test power, we ran the energy-02 viewset in SPECviewperf 13 and recorded the peak power consumption. Idle power consumption was recorded after the system had idled at desktop for a while.

The Aorus board recorded a marginally higher system power draw, but it's again not a difference I'd lose sleep over.



The table below shows the clock speeds we achieved, along with the CPU vCore, multiplier, and RAM frequencies. We've also included the respective BIOS versions of the boards for those who are keen to know such details.

  BIOS version CPU core ratio BCLK (MHz) Vcore (V) RAM frequencies (MHz) Maximum overclock (GHz)
ASUS ROG Zenith Extreme 1402 41 100 1.438 3,200 4.1
Gigabyte X399 Aorus Xtreme F4c 41 100 1.4375 3,200 4.1

The Aorus board produced slightly better numbers after overclocking, but the ASUS model offered a better BIOS interface and layout. Most of the key settings, such as voltage settings, are located on the same menu page, so you don’t have to toggle between different pages as on the Aorus motherboard.

In addition, the ROG Zenith Extreme offered a relatively hassle-free experience as the system booted up and ran Cinebench with no problems after simply changing the CPU core ratio and leaving everything else on Auto. The board seemed content to adjust the voltages accordingly without much need for manual adjustments on my end.

On the other hand, the X399 Aorus Xtreme required me to set LLC to High and adjust the CPU Vcore manually. That said, it's not a super big deal, and most people who are even looking at this section of the BIOS will probably be comfortable with making manual tweaks anyway.

The Good
Good overclocking performance
Packed with features, including 10G Ethernet
Rock solid build
The Bad
RAM slots a little too close to CPU socket
BIOS interface could be better designed
