GIGABYTE has another motherboard coming out supporting AMD’s Threadripper CPUs, the X399 Designare EX. The Designare EX is slated to be their flagship motherboard for the X399 chipset and includes additional features over the AORUS Gaming 7, bringing dual Intel NICs (over a Killer NIC), Intel WiFi, Thunderbolt 3 add-in card support, and an integrated backplate for increased structural rigidity and aesthetics. This board fills out GIGABYTE's short X399, with the AORUS Gaming 7 a bit further down the line. In the past, we have seen Gaming 3, and Gaming 5 versions so there is still room for something a bit less expensive in the GIGABYTE lineup in the future.

Read our AMD Threadripper X399 Motherboard Overview: All the X399 Motherboards here.

One of the first things one may notice on this board is lack of RGB LEDs compared with the AORUS Gaming 7. On the Gaming 7, where RGB LEDs are just about everywhere, the Designare EX on the other hand only has a few under the PCH heatsink. Aside from that, design aesthetics are remarkably similar, with only the color scheme changed from black colored heatsinks and shrouds (with the AORUS name) to all silver, and the GIGABYTE name on the shrouds instead. The PCH heatsink is the same shape with a different accent plate for the Designare, marking a not to GIGABYTE's aimed market for this product: design professionals. Also included is an integrated I/O shield giving it a more high-end feel.

Outside of what has been listed above, the specifications for the Designare are very similar to the Gaming 7, as it uses the same base PCB. Keeping on the platform trend, the Designare EX supports quad channel memory at two DIMMs per channel, for eight total supporting up to 128GB. What looks like an 8-phase VRM uses the same style main heatsink connected to a secondary heatsink via a heatpipe located behind the rear I/O. Being the same PCB, the power delivery is also listed as ‘server class’ like the Gaming 7, using fourth generation International Rectifier (IR) PWM controllers and third generation PowIRstage chokes. EPS power is found in its normal location in the top left corner of the board, with one 8-pin and one 4-pin.

In the top right corner of the board are five 4-pin fan headers along with an RGBW header for LEDs. Two other RGB headers are found across the bottom of the board, including another RGBW header. USB connectivity uses an onboard USB 3.1 (10Gbps) header from the chipset close to the eight SATA ports. There is a USB 3.0 header on the bottom of the board, two USB 2.0 headers near the power buttons, and a TPM header at the bottom of the board.

Like the AORUS Gaming 7, the Designare EX supports three M.2 drives. The two locations between the PCIe slots support up to 110mm long drives, while the third below the PCH heatsink can fit up to 80mm drives. All locations come with additional heatsinks to keep the drives underneath cool. The Designare EX uses the three M.2 slots instead of a separate U.2 connector.  For other storage, GIGABYTE has equipped the board with eight SATA ports. The 5-pin Thunderbolt 3 header, required for add-in Thunderbolt 3 cards and unique for X399 to this specific GIGABYTE X399 board, is located just above the SATA ports. We are asking GIGABYTE if they plan to bundle a Thunderbolt 3 add-in card with this model, and are awaiting a response.

The rear of the motherboard, like some other designs on the market, uses a rear backplate to assist with motherboard rigidity. The thinking here is that these motherboards are often used in systems with multiple heavy graphics cards or PCIe coprocessors, such that if a motherboard screw is incorrectly tightened, the motherboard might be required to take the load and eventually warp. With the back-plate in place, this is designed to distribute that potential extra torque throughout the PCB, minimising any negative effects.

The PCIe slots are the same as the Gaming 7 also, with four of the five sourcing its lanes directly from the CPU. The slots used for GPUs are double-spaced and support an x16/x8/x16/x8 arrangement. The middle slot supports PCIe 3.0 x4 connection fed from the chipset. The middle slot can be used for additional add-in cards, such as a Thunderbolt 3 card.

Next to the PCIe slots is GIGABYTE’s audio solution, using a Realtek ALC1220 codec and using an EMI shield, PCB separation for the digital and analog audio signals, filter caps (both WIMA and Nichicon), and has headphone hack detection. GIGABYTE also uses DAC-UP, which delivers a more consistent USB power supply for USB connected audio devices. 

Rear IO connectivity on the Designare EX is also like the AORUS Gaming 7. The only difference will be the additional Ethernet port as this model uses dual Intel NICs. Because of the USB 3.0 support from the CPU, the rear IO has eight USB ports, in yellow, blue, and white. There are also two USB 3.1 (10 Gbps) ports from the chipset, one USB Type-C. Network connectivity differs here with the Designare EX using two Intel NICs (we imagine some mixture of I219V or I211AT) and does away with the Rivet Networks Killer E2500 found on its little brother. Last, are a set of audio jacks including SPDIF. 

Pricing was not listed, however, if it is slated to be the flagship of the X399 lineup, pricing is expected to be a higher than the already released X399 AORUS Gaming 7 at $389.99 on Amazon. GIGABYTE says the Designare EX will be available come Mid-October.

After speaking with GIGABYTE, it seems that Thunderbolt 3 support will perhaps still be in limbo:

Thunderbolt 3 certification requires a few things from the CPU side like graphical output which we haven't been able to do. We expect this will be developed upon through Raven Ridge and possibly get more groundwork down to activate TB3 on the X399 Designare EX.

The header will remain, though TB3 use / full TB3 enablement will be at a later date. It seems like GIGABYTE has taken note that users are interested in TB3 on AMD.

    I don't believe this motherboard has full TB3 - if you look at update on 20th (today), only if you have Raven Ridge processor - which I would think would be quite limited for AMD platform.

    What is the color coding for USB 3.0? I thought it was supposed to be blue, but now also white and yellow?
  • DanNeely - Wednesday, September 20, 2017 - link

    Just like with 2.0 ports that're normally black but are occasionally colorcoded differently when they have something extra/special hooked up to them. From the markings on this board, the white port can probably be used to flash the BIOS. The two yellow ports have better power filtering which is supposed to benefit USB audio devices by reducing noise. I don't know much about it, but Tech Report's reaction when they started doing it was that it was a feature for the gold plated monster hdmi cables crowd.

    Out of sheer curiosity, is it possible for motherboard manufacturers to design a prototype x399 motherboard, in which the following are directly connected to the CPU PCie lanes:

    Usb3.1g2 X2 4lanes
    Usb3.1g1 X4 4lanes
    10gbit Ethernet x1 4lanes
    WiFi x1 4lanes
    Tb3port x1 4lanes
    SATA x4 4lanes
    M.2 pciex4 x1 4lanes
    Usb3.1g2 front X2 4lanes
    Pciex16 X2 32lanes

    That would mean no bottlenecking while concurrently using multiple of these ports... The chipset would then be almost redundant...
  • DanNeely - Wednesday, September 20, 2017 - link

    That particular config would leave the chipset completely unconnected and thus totally useless. 4 of the nominal 64 PCIe lanes are used for the chipset; meaning only 60 are available for general use.
  • prateekprakash - Wednesday, September 20, 2017 - link

    Ok, then just remove one of the x4 connection from the above list (eg: front port headers )
    Then wouldn't it be an innovation in the motherboard space?
  • DanNeely - Wednesday, September 20, 2017 - link

    That'd be technically feasible, but the >90% of the market that look at price and the number of feature boxes checked and are going to see you either have 2 x16 slots instead of 4, or have your lanes allocated 8/8/8/8 instead of 16/8/16/8 in 4 way mode and decide to drop your board as being gimped.

    If this was going to be done anywhere it'd probably be on an mATX board where 2 16x slots is a reasonable config. OTOH so far none of them have been announced yet.

    It has long occurred to me that fully digital DP could act as a HB digital bridge between multiple teamed discrete gpuS, to bypass the restrictive pcie bus.
