GIGABYTE put eight fan headers on this motherboard. The two in red seem capable of 2A of power while the rest might be 1A. One of the right fan headers is occupied by the hidden VRM cooling fan. All fan headers are hybrid headers that support PWM and DC operation modes. The two headers circled in green are for two external temperature probes that are included in the package. Overall the motherboard has a white and silver color theme, and the back of the motherboard has a metal back plate that will stabilize the PCB and cool the back of the VRM.

GIGABYTE X299 Aorus Master (Intel X299) Motherboard Review 08 | TweakTown.com

The IO shield offers a clear CMOS button, a power button, WIFI antenna, six USB 3.0 ports (white is for QFlash Plus), 2.5G LAN, 1G LAN, USB 3.1 typeA, USB 3.1 type-C, and gold plated audio with S/PDIF out.

With a 44-lane CPU the PCI-E will be x16/x0/x16/x8 or x16/x8/x8/x8, and with a 28-lane CPU they operate at x16/x0/x8/x0. The M.2 slots all have heat sinks, and the top one is connected to the CPU and always is at x4 PCI-E 3.0, SATA M.2 drives are not supported and VROC key is required for RAID. The other two M.2 slots support both x4 PCI-E 3.0 and SATA M.2 drives, with the middle one disabling SATA3_0 if a SATA M.2 drive is used and the bottom one disabling four SATA ports if any drive is installed (SATA3 ports 4-7).

GIGABYTE X299 Aorus Master (Intel X299) Motherboard Review 11 | TweakTown.comGIGABYTE X299 Aorus Master (Intel X299) Motherboard Review 12 | TweakTown.com

There are eight SATA6Gb/s ports on this motherboard, all from the PCH, some of which share lanes with the bottom two M.2 drives. There is also a PCI-E power connector for extra PCI-E power. There is a USB 3.1 type-C header and a USB 3.0 header right under the 24-pin power connector.

GIGABYTE X299 Aorus Master (Intel X299) Motherboard Review 13 | TweakTown.comGIGABYTE X299 Aorus Master (Intel X299) Motherboard Review 14 | TweakTown.com

At the top right corner of the motherboard we have two CPU power connectors, an addressable RGB LED header with jumper for voltage selection, and an RGB LED header. There is a Thunderbolt 3 GPIO header and a VROC header just above the front panel headers.

GIGABYTE X299 Aorus Master (Intel X299) Motherboard Review 15 | TweakTown.comGIGABYTE X299 Aorus Master (Intel X299) Motherboard Review 16 | TweakTown.com

In the bottom middle of the motherboard we find another addressable RGB LED header with voltage selection jumper, an RGB LED header, a BIOS selector switch, a dual BIOS disable switch, a reset switch, and a POST code display. The USB 3.0 internal header at the bottom of the motherboard supports USB TurboCharge, which supports QuickCharge. There are two USB 2.0 internal headers at the bottom of the motherboard.

The VRM here is using the high quality Intersil Smart Power Stage ISL99227 60A integrated power stages with exposed top for better cooling. GIGABYTE also increased copper to 2oz on this motherboard to help with cooling. The power stages are in a 12 phase configuration and controlled by the new Intersil digital PWM, the ISL69138.

GIGABYTE X299 Aorus Master (Intel X299) Motherboard Review 22 | TweakTown.comGIGABYTE X299 Aorus Master (Intel X299) Motherboard Review 23 | TweakTown.com

Six ISL6617 phase doublers are used to increase phase count to 12. Both the VCCSA and VCCIO get their power from small PowerPAKs from On Semiconductor, and they should be able to get the job done, and the VCCIO is controlled by the ISL69133.

GIGABYTE X299 Aorus Master (Intel X299) Motherboard Review 24 | TweakTown.comGIGABYTE X299 Aorus Master (Intel X299) Motherboard Review 25 | TweakTown.com

Each memory VRM uses the same On Semiconductor NTMFS4C06N for the two low-side MOSFETs and single high-side MOSFET, and they are each controlled by a Ricktek RT8120 PWM controller.

GIGABYTE's X299 UEFI on their X299 Aorus Master is much like that of GIGABYTE's other X299 motherboards. It has all the settings you need to configure your system for overclocking, and we spotted a new one for GIGABYTE. GIGABYTE had added in a PCI-E bifurication setting for all four slots, so you can have a x16 slot with x16 of PCI-E split into x4/x4/x4/x4 for four M.2 drives and RAID them with VROC. Fan control is also present in the form of a GUI.

GIGABYTE X299 Aorus Master (Intel X299) Motherboard Review 87 | TweakTown.com

Note on Thermal Images: In the temperature section, we use our Seek thermal imaging camera to capture the surface temperatures of major components on the board. I look at the VRM and then all other things that light up the screen. If there is something to worry about, then I will state it. Otherwise, I will just show the hotter running parts of the board for fun. Unless some component is over 80-90C, then there isn't anything to worry about.

All systems will act differently, so I will look for commonalities, such as how far from the VRM the heat spreads through the PCB and the difference in temperature between the front side and backside of the PCB. Keep in mind, the majority of the heat from the VRM goes into the PCB as it is a giant soldered on copper heat sink. A larger difference in temperature between the back and front of the PCB points towards a more effective heat sink.

Thermal Testing at Stock Speeds:

The image on the left is always at idle, and the image on the right is at load. During ALL TESTS, fans above the VRM that cool the CPU cooler's (Corsair H110i) radiator are turned on to high (12v).

Up-close of the back of the VRM.

Overall VRM thermal performance is excellent, but remember these are results at stock settings, not a 4.7GHz 9980XE. We see solid thermal distribution, and the active fan and heat sinks do seem to help cool the VRM and PCB. We see a 2C increase on the front and a 4C increase on the rear of the PCB. Overall excellent, but do keep air flow over the VRM area in your mind if heavily overclocking the 9980XE.

What's Hot, What's Not & Final Thoughts

What's Hot

Intersil Smart Power Stages: Interstil's new Smart Power Stages are rated up to 60A each and offer an exposed top, so cooling is much more efficient. We are seeing motherboard vendors do two types of things on their latest X299 and X399 motherboards; their they have moved down the socket and RAM DIMMs and as a result move the PCI-E layout down or they have upgraded parts. In some cases they have done both. In this case we get a combonation that works quite well because it's not only 12x60A power stages, it's also got a very good cooling solution for this price point.

Upgraded Audio and LAN: We find our typically 1Gbit Intel NIC, but we also find a 2.5Gbit Realtek controller, which is a nice add-on. While this price point isn't the most expensive for the X299 chipset, GIGABYTE did add in an additional DAC, the ES9218PQ, which also has an integrated headphone amplifier.

Value: As the second most expensive GIGABYTE X299 motherboard, the Master aims to offer a balance between price and performance, and we like the price ofthis motherboard. It has the same VRM as the Designare EX from GIGABYTE, and that motherboard is $150 more expensive. It has all the latest features like USB 3.1 (1Gbps) and USB BIOS recovery as well as RGB LED strip support.

What's Not

Depends on what you are looking at: Do you want a bunch of integrated RGB LEDs in your motherboard? Well, this one is a bit more basic in that regard, with just a few in discrete places. Do you want the latest Wireless AC and BT 5.0 technology? Well this one does offer the previous generation controller rated up to 867Mbps and BT 4.2. Do you need more than 7 fan headers? Well, you might need to get a fan controller to support more.

Final Thoughts

GIGABYTE's X299 Aorus Master has replaced the Gaming 7 series of motherboards for the X299 chipset from GIGABYTE, and comes in with a better VRM and roughly the same feature set but a few less RGB LEDs for around the same price.

GIGABYTE X299 Aorus Master (Intel X299) Motherboard Review 94 | TweakTown.com

It's aimed to provide enough OC headroom to handle an 18 core CPU, while not breaking the bank leaving room for more RAM and storage.
