Gigabyte X299 Aorus Gaming 7 Motherboard Review

How We Test

More cores create higher thermal and power loads that can push other hardware to its limits, yet the parts we’re hoping to push to the limit are all on the motherboards. Intel’s 10-core, 20-thread Core i9-7900X CPU is a great product for stressing the voltage regulators of various X299 motherboards, particularly under our full-AVX-load overclocking stability test.

Test Hardware

NetworkIntegrated Gigabit Networking
Graphics DriverGeForce 382.53

The tremendous heat produced by the Core i9-7900X required us to use nothing less than our award-winning Fractal Design S24 liquid cooler system sample. Getting its fans to blow sufficiently over each motherboard’s voltage regulator required additional design consideration: Of our leftover case review samples, Cooler Master’s HAF-XB had the best layout.

    I'm still hoping that future boards don't limit features on their boards. I don't want to see "if you used m.2 drive you loose 2 Sata connections " anymore... then this boards with 2 or 3 m.2 if you used them, then you lose 4/6 Sata connections out of 8?

    Just not make sense to me.

    I understand why you would say this. I also think that every feature on a motherboard should be 100% usable.

    What's happening though is that there are more features on the board than there is bandwidth for it. If you enable one feature, it eats the resources needed for another. Have you ever worked at a job that was understaffed? It's like that.
  • What i like about x299 platform is that PCIe frequency just like with 1366 socket is not affected when you change BLCK. I wish it is the same case for X99, would make possible to overclock Xeons easily.
  • This price is too much. Waiting for < $200 X399 AMD or X299 Intel and they will come in about year.

    until intel quits screwing around and comes up with a decent plan instead of playing it fast and loose there is really no reason to test any of its products. there are far too many variables because of the rush job they did. youre just going to have to retest when they come to their senses and thats a lot of wasted time and resources on everyones part.

    So you mean just like Ryzen boards? If everyone followed your advice, there wouldn't be any motherboard reviews for either brands.

    Does anybody know if it is "OK" to put your graphics card in any of the 5 PCIe slots on the motherboard. I would probably place my graphics card in the PCIe slot farthest from the CPU so as not to cover up the LED graphics and provide adequate ventilation. Something in the back of my mind tells me that not all PCIe slots are equal and you might be penalized for doing so.

    I know back in the day, the PCI slots nearest the CPU had the least latency. I don't know if that's still relevant.

    Short answer no. The furthest PCIe slot is x8. There are two x16 slots: the one closest to the CPU and the third from the CPU.

    This is still true. Typically the one closest to the CPU is x16 where as others are typically x8 or x4.

    that one slot seems separated so my guess is yes it's different somehow

    It's worse than that. The problem is that Kaby Lake-X has only 16 lanes and everyone is trying to make their boards Kaby Lake-X compatible. If not for Kaby Lake-X, all boards would be optimized to use AT LEAST 28 CPU lanes.

    The second slot is fed by the same lanes as the fastest M.2 slot, so I'd skip using it if you don't need it.
    The fourth slot is fed by the chipset, which only has an x4 uplink, so I'd skip using it if you don't need it.
    The bottom slot takes eight lanes from the top, except if you have a Kaby Lake-X processor, in which case it's disabled. Rather than say "I'd skip using it" concerning the slot, I'll say that about Kaby Lake-X.
  • Are any of these clueless manufactures will make motherboard without gay looking RGB but to actually have two 8pin CPU connectors and put copper based sink on VRM with active fan on top of it?

    is intel new skylake-x also meant as a replacement for 1151 skylake or it only replaces it's broad well counterpart.

    It's a replacement for Broadwell-E on 2011-v3. It's a different market than 1151.

    Really, for long term stability, the 7900X should only be OC to 4GHz max. My 6800K can boost and use to browse the webs all day at 4.2 GHz with a voltage of 1.242 V without any problem. But, it requires 1.272 V to play Wildlands without any crash to BSOD. When you benchmark or stress test, you test to CPU in isolation, but when you play game, everything is running at full speed, and the CPU has to take care of that, providing the bandwidth to the graphics card and so on...

    I really think that the Z270 motherboards were the last product lines that all these Taiwan manufacturers made with a correct balance of price versus performance. But with the X370 and now the X299, all the manufacturers are resorting to gimmicks and kitsch, adding lots of futuristic-looking plastic parts that trap heat inside VRMs, PCHs, and M.2 cards, instead of dissipating heat, and piling on the RGB effects. This reminds me of the Z77 mobos from 2012 when Gigabyte released a 32-phase CPU VRM, and not to be outdone, Asus countered with a 40-phase CPU VRM, and it was achieved with lots of phase doublers.

    If you watch the latest YouTube teaser video that Asus release for their upcoming ROG Rampage VI Extreme https://www.youtube.com/watch?v=4dY8LGeu0UE , there are also lots of pretty RGB effects. But if you look at der8auer's previous video showing a prototype of Asus' redesigned VRM heatsink https://www.youtube.com/watch?v=hejMP5hrhjc&t=78s unfortunately Asus still favored style over substance, and the VRM heatsink in this new Asus video shows very shallow fins on the VRM heatsink for far less surface area for heat dissipation :-( In the der8auer video, the prototype heatsink has deeply cut fins. The very shallow fins shown in the new Rampage VI video are very shallow, as if Asus thought that deeply-cut heatsink fins are ugly or something. If you watch Tiny Tom Logan's preview of the MSI XPower Gaming AC https://www.youtube.com/watch?v=KQk_xQ6HTFs&t=283s the heatsink has more exposed fins both on the VRM and on the big heat-piped heatsink next to the I/O panel. Asus knows how to make properly-design heatsinks on their mobos. For example, the Asus X99-E-WS workstation mobo has excellent heatsink designs. The X299 essentially needs to have a robust workstation build to it if it is to properly support 12-core and 18-core CPUs. But these manufacturers are so fixated on adding the word "gaming" to all their X299 mobos that they are making their mobos look like toys.

    So ever since the Z270 mobos, all the mobo makers are trying to out-style their competitors by making their mobos look the best visually, at the expense of performance.

    Z270 is a current product. X299 is a replacement for X99.

    Yes, I am fully aware that X299 replaces X99. My point of my original post is that the Z270, X99, Z170, and earlier mobos did not sacrifice substance for style, whereas with their X370 and X299 mobo designs, all the manufacturers are now focusing more on style at the expense of substance, with the increased "style" being to add on lots of futuristic plastic parts and RGB effects and the decreased "substance" being the additional VRM performance and proper heat dissipation from the VRM and M.2 areas on the new mobos that are needed to properly manage mega-core CPUs and hot NVMe M.2's.
