Board Features

Aside from the RGB LEDs, the key additional features on this board are the dual network interfaces bundled with the Wi-Fi, the use of three M.2 slots for storage (with heatsinks), and having all the PCIe slots as full length slots, which is something usually only seen on higher-end workstation motherboards. GIGABYTE also pulls the stops out on USB 3.1 (10 Gbps) support, using a Realtek hub to expand the ASMedia ASM3142 ports available. Of course this has knock-on effects for combined bandwidth, but it is still relatively new to see this type of port be expanded in this way.

For a board of this price, what is missing is really a U.2 port, however GIGABYTE will state that with so many M.2 ports, using an M.2 to U.2 converter will have to come into play here.

Test Bed

As per our testing policy, we take a high-end CPU suitable for the motherboard that was released during the socket’s initial launch and equip the system with a suitable amount of memory running at the processor maximum supported frequency. This is also typically run at JEDEC sub timings where possible. It is noted that some users are not keen on this policy, stating that sometimes the maximum supported frequency is quite low, or faster memory is available at a similar price, or that the JEDEC speeds can be prohibitive for performance. While these comments make sense, ultimately very few users apply memory profiles (either XMP or other) as they require interaction with the BIOS, and most users will fall back on JEDEC supported speeds - this includes home users as well as industry who might want to shave off a cent or two from the cost or stay within the margins set by the manufacturer. Where possible, we will extend our testing to include faster memory modules either at the same time as the review or a later date.

Readers of our motherboard review section will have noted the trend in modern motherboards to implement a form of MultiCore Enhancement / Acceleration / Turbo (read our report here) on their motherboards. This does several things, including better benchmark results at stock settings (not entirely needed if overclocking is an end-user goal) at the expense of heat and temperature. It also gives, in essence, an automatic overclock which may be against what the user wants. Our testing methodology is ‘out-of-the-box’, with the latest public BIOS installed and XMP enabled, and thus subject to the whims of this feature. It is ultimately up to the motherboard manufacturer to take this risk – and manufacturers taking risks in the setup is something they do on every product (think C-state settings, USB priority, DPC Latency/monitoring priority, overriding memory sub-timings at JEDEC). Processor speed change is part of that risk, and ultimately if no overclocking is planned, some motherboards will affect how fast that shiny new processor goes and can be an important factor in the system build.

**** Please note due to circumstances out of our control we were forced to use a new CPU for this motherboard and the remainder of our X299 testing. While this switch will not affect the majority of results, it will have an effect on our power testing and overclocking. The stock voltage will be different as will the voltage needed to overclock. Because of this, the power testing and overclocking results are not directly comparable. They are noted by an asterisk in the results for clarity. 

Many thanks to...

We must thank the following companies for kindly providing hardware for our multiple test beds. Some of this hardware is not in this testbed specifically but is used in other testing.

Thank you to ASUS for providing us with GTX 980 Strix GPUs. At the time of release, the STRIX brand from ASUS was aimed at silent running, or to use the marketing term: '0dB Silent Gaming'. This enables the card to disable the fans when the GPU is dealing with low loads well within temperature specifications. These cards equip the GTX 980 silicon with ASUS' Direct CU II cooler and 10-phase digital VRMs, aimed at high-efficiency conversion. Along with the card, ASUS bundles GPU Tweak software for overclocking and streaming assistance.

The GTX 980 uses NVIDIA's GM204 silicon die, built upon their Maxwell architecture. This die is 5.2 billion transistors for a die size of 298 mm2, built on TMSC's 28nm process. A GTX 980 uses the full GM204 core, with 2048 CUDA Cores and 64 ROPs with a 256-bit memory bus to GDDR5. The official power rating for the GTX 980 is 165W.

The ASUS GTX 980 Strix 4GB (or the full name of STRIX-GTX980-DC2OC-4GD5) runs a reasonable overclock over a reference GTX 980 card, with frequencies in the range of 1178-1279 MHz. The memory runs at stock, in this case, 7010 MHz. Video outputs include three DisplayPort connectors, one HDMI 2.0 connector, and a DVI-I.

Thank you to Crucial for providing us with MX300 SSDs. Crucial stepped up to the plate as our benchmark list grows larger with newer benchmarks and titles, and the 1TB MX300 units are strong performers. Based on Marvell's 88SS1074 controller and using Micron's 384Gbit 32-layer 3D TLC NAND, these are 7mm high, 2.5-inch drives rated for 92K random read IOPS and 530/510 MB/s sequential read and write speeds.

The 1TB models we are using here support TCG Opal 2.0 and IEEE-1667 (eDrive) encryption and have a 360TB rated endurance with a three-year warranty.

Thank you to Corsair for providing us with Vengeance LPX DDR4 Memory, HX750 Power Supply, and H115i CPU Cooler

Corsair kindly sent a 4x8GB DDR4 2666 set of their Vengeance LPX low profile, high-performance memory for our stock testing. The heatsink is made of pure aluminum to help remove heat from the sticks and has an eight-layer PCB. The heatsink is a low profile design to help fit in spaces where there may not be room for a tall heat spreader; think a SFF case or using a large heatsink. Timings on this specific set come in at 16-18-18-35. The Vengeance LPX line supports XMP 2.0 profiles for easily setting the speed and timings. It also comes with a limited lifetime warranty. 

Powering the test system is Corsair's HX750 Power Supply. This HX750 is a dual mode unit able to switch from a single 12V rail (62.5A/750W) to a five rail CPU (40A max ea.) and is also fully modular. It has a typical selection of connectors, including dual EPS 4+4 pin four PCIe connectors and a whopping 16 SATA power leads, as well as four 4-pin Molex connectors.

The 135mm fluid dynamic bearing fan remains off until it is 40% loaded offering complete silence in light workloads. The HX750 comes with a ten-year warranty. 

In order to cool these high-TDP HEDT CPUs, Corsair sent over its latest and largest AIO in the H115i. This closed-loop system uses a 280mm radiator with 2x140mm SP140L PWM controlled fans. The pump/block combination mounts to all modern CPU sockets. Users are also able to integrate this cooler into the Corsair link software via USB for more control and options.

    You misunderstand. It isn't about whether it inconveniences or affects them in any way. It is about needing a reason to bitch about something.

    Fucking killer NIC. That shit cannot die soon enough. Why even waste space on that, even 10GbE and an intel 1GbE would make more sense.

    I was looking at Gigabyte boards a bit ago and anything with decent features was ruined by KillerShit, so I switched to ASUS for PRO/A series without dumb shit thrown in.
  • Ian Cutress - Friday, January 26, 2018 - link

    I'll forward your concerns to Rivet. Anything specific you don't like about Killer, especially the latest hardware?
  • PeachNCream - Friday, January 26, 2018 - link

    Hey Ian, since Joe has the hardware already, is it possible for Anandtech to do some more in-depth benchmarking of the Killer ethernet and wireless cards on this motherboard? Internet gaming tests under real world conditions might help us put Killer's value proposition into perspective.
  • oRAirwolf - Friday, January 26, 2018 - link

    I agree with peachncream. Killer has made some absolutely awful networking products in the past that were further crippled by their horrendous drivers and unnecessary software. It has left a bad taste in everybody's mouth and very few if any PC enthusiasts are happy to see their products in a motherboard. From what I see online, it seems as though most people either don't install their software or uninstall it if it comes pre-packaged. Rather than forwarding complaints to deaf ears at Rivet Networks, it would make a lot more sense to do some very detailed benchmarking, including Aquantia's new chipsets, showing the pros and cons of each solution and the impact they have on things like latency, CPU usage, bandwidth, and game perfomance. I am especially interested to see some benchmarks pitting the new Aquantia chipsets against Intel's 10gbe offerings like the X540, X550, and X710 with RJ45 ports.
  • Notmyusualid - Saturday, January 27, 2018 - link

    I disagree.

    There is nothing wrong with their hardware in my opinion.

    Just install the basic driver, or the Qualcomm driver, and you will be unable to tell the difference from your typical Intel NIC, on any consumer device. You don't have to install their network suite.

    Meanwhile I've had no end of trouble with my X540 10Gb/s NICs. So much so - I returned it for replacement. And whilst I've not been home yet to try the replacement, I'm not confident of good results.

    Hello Ian from Australia! I signed up just now to reply to your question to timecop1818 and I'll give you my impression of previous killer standalone $200 network cards and their embedded chipset Ethernet products. Basically the product is of no real benefit over any other networking product and in one specific case I'll mention later on completely useless. It supposedly originally prioritized gaming packets within the machine over other traffic which might have been of some use at a lan event where you bring your own machine but then you probably wouldn't be using your machine for anything else at the time so gaming traffic was probably all that was going out over the network anyway, so no benefit there and these days most people do their gaming over the internet anyway.

    When I only had 8/1 Adsl1 and (max speed) 12/1 Adsl2 available for internet the same would apply as you couldn't do anything else because even if you downloaded other stuff at say 50% of Adsl download speed the 50 byte acknowledgement packets going out to request the next packet be sent down to you would blow out pings from 40-60 to 200 as the upload speed of 1 Mbit was just way too slow and congestion occurred (think goat track compared to 8 lane freeway) so again I'm left with just gaming traffic only because I couldn't do anything else so no benefit over any other ethernet chipset again.

    Now that I'm on fibre at 100/40 and I have a truckload of bandwidth I can be gaming and also downloading Nvidia drivers at 11 MB's and gaming pings only slightly rise from 22 to 26 so killer is not needed at all again as any other Ethernet chipset will do just fine.

    Software: According to their website https://www.killernetworking.com/driver-downloads it's windows only and nothing else. I have a 4930K and a Gigabyte X79S-UP5-WIFI board which has both Intel and Realtek ethernet connectors on it and that's my Windows 7 gaming machine. My other identical board has an I7-3820 cpu and I'm testing Solaris 11.3 as a ZFS NAS and for whatever reason the Intel Ethernet connector came up as "mis-configured" and I couldn't work out why that was so I plugged in the network cable into the other Realtek connector and off I went. If I had a killer ethernet instead of Realtek I'd either have to figure out the Intel mis-configuration or get another Gbe network card (probably Intel) and plug it in as Killer have no Solaris, BSD or Linux drivers which is pretty useless of them.

    For those people who find that Gbe isn't fast enough and are looking at 10Gbe that's not expensive the speed increase stated on their webpage https://www.killernetworking.com/products/killer-e... going from 940 Mbs to 1102 Mbs may as well be totally insignificant as all it is is just re-inventing the existing wheel. I picked up about a year ago very cheap (approx USD$ 50) Mellanox QDR infiniband cards when they deprecated the technology and these cards are 40 Gbs Infiniband/10 Gbs Ethernet capable so if this chipset actually was 100 Base T (or even 50 or 25) then and only then would I possibly be interested as probably would other people as well.

    No one wants to muck around with a "control center" for Ethernet as I just want the network to "just work" when I plug the cable in and I'm happy with some crappy no-name no-brand software TCP/IP stack that works reliably even if it only goes at say 90% of maximum speed. I hope its not anywhere near as useless as the Nvidia Firewall software I once had the misfortune to install as it completely stuffed up my network port and rendered it non-functional which still didn't work even after I uninstalled the software and I had to reformat the hard drive and re-install windows to fix that problem.

    Anyway that's everything that's CURRENTLY wrong with this product and nothing that's right with it as I have explained in detail above, If they posted drivers for all the other OS's then it might get half way to being merely usable. Feel free to pass my entire comment over to Rivet and I look forward to any reply to any part of my comments posted back here but I'm not holding my breath in anticipation of that.

    Cheers

    They are the answer to a non existant problem... or better the real problem is the Internet speeds people have and there's nothing Killer can do about it. People that have slow internet already turn off any sharing software when they play games and those that have a fast one don't care cause they have more than enough, those in-between will just turn off any bandwidth hungry apps just for a piece of mind.
    On bittorrent if you share at a very slow speeds, as would be the case if you play and torrent at the same time on a slow connection no one will connect to you or kick you if the speeds are too low, no one wants to spend time and resources on a connection that is as fast as a snail.
  • Tamz_msc - Friday, January 26, 2018 - link

    From what I have read recently Killer LAN is mostly fine as long as you don't install their software. Linux support might be spotty though.
