Board Features

MSI was one of the first boards with PCIe reinforcement, stating that it assists system integrators in reducing RMA rates from users mishandling their equipment. Since then every manufacturer now has a solution for this, and marks how the industry is moving forward. MSI is even doing it on the DRAM slots on the X99A Gaming Pro Carbon.

The internal USB Type-C port is an interesting addition – typically we see these for USB dongles to licence software, but I believe MSI’s thinking here is for front-panel USB Type-C ports than can be used via a connecting cable.

Visual Inspection

As with most X99 motherboards, the Gaming Pro Carbon is large (and in charge?). One of the first things a user will notice is the color scheme, black/dark gray with silver accents, but that the silver accents are mostly due to the PCIe and DRAM slot reinforcement. This reinforcement does make the board somewhat heavier than most, and although certainly capable I do not suggest holding the board in only one corner due to the self-applied torque the board will generate.

With the carbon styling, the whole PCB gets a matt black finish, making the traces between components less obvious. As a result, the socket area looks clean for any users wanting to prepare the motherboard for sub-zero cooling to prevent moisture. Above the socket are eight premium chokes with a heatsink over the power phases, but based on the boards pricing this is not connected to other heatsinks. The socket area has immediate access to four 4-pin fan headers: a CPU header to the top left above the DRAM slots, a liquid cooling pump fan header in the top right above the DRAM, a SYS fan header next to this, and the fourth is between the 24-pin ATX connector and the right-hand side DRAM slots. There is one other header on the bottom row of the board.

As mentioned before, the DRAM slots are reinforced to guard against bending or additional stress that might occur during abnormal use. We reviewed a motherboard recently that also had this effect, but the spacing between the DRAM slots was uneven (due to resistors in-between), and it looked odd. The X99A Gaming Pro Carbon doesn’t have this issue through. Interestingly, the primary DRAM slots on each side are the outermost slots and then two inside that, in a 1/2/3/4/8/7/6/5 configuration left to right, and 1/3/5/7 are the primary ones. Typically we see a 1/2/3/4/5/6/7/8, which may lead to an abnormal balance when only four slots are populated. Each of the slots uses single sided latches, making it easier to remove memory when a large GPU is in place but users should make sure that the DRAM is firmly pushed into each slot.

On the top right of the motherboard, next to the two fan headers, is a two-digit debug display which can be helpful for debugging any POST issues. After POST it doubles as a CPU temperature reading, and can be useful if a processor is going up in temperature due to dust in the chassis. Beneath this are the 24-pin ATX power connector, a 4-pin fan header, and a USB 3.0 header from the chipset. Next to the USB 3.0 header is an internal USB 3.0 Type-C port, useful for internal USB Type-C devices or, as I think MSI intends, for users to place a Type-C pass through on the front panel of a chassis. We get a second USB 3.0 chipset header next to the Type-C, at 90 degrees similar to the SATA ports.

The storage area of the motherboard is a little varied. Remember with X99 that the chipset supports 10 SATA ports, with the first six from the primary AHCI controller and supporting RAID, while the secondary AHCI controller can supply four ports but these are not for RAID. On the board itself we start with six SATA ports, and the first two pairs are from the primary AHCI controller but the third pair is from the secondary controller and not for RAID. Then we get a U.2 port, which I want all motherboard manufacturers to have as there is at least one consumer drive that supports it, but then we get another two SATA ports. This pair is from that secondary controller, and then over the power/reset buttons is a third pair from that primary AHCI controller for RAID. This final pair can also support a SATA Express connection, despite the death of that standard for storage late last year.

There is also an M.2 slot between the PCIe slots, and it supports PCIe 3.0 x4 or SATA drives. It is worth noting that there is a conflict between this and the U.2 port: in PCIe mode, only one can be used at once. For users who want more than one PCIe device, a PCIe slot will have to be used.

Moving to the bottom of the board, aside from the SATA ports, we get power/reset buttons on the right side along with a big red knob. This is a rotating switch with 8 points that manages the system level overclock. In previous generations from MSI we had the single button OC Genie, well it is now upgraded to eight different options, all of which are in the BIOS and we’ll go through them then. Beside all these buttons is a BIOS select switch, a SLOW jumper for LN2 users wanting to boot into a slow mode, and a header for the LEDs in the chipset heatsink (see below).

Moving to the bottom left of the board and we get two USB 2.0 headers, an LED power header for an LED strip, and then eventually the front panel header. I’m surprised the front panel header is this far along, meaning that system builds will require long front panel leads and sufficient space to make sure they are hidden if you want an aesthetic build from this motherboard. Aside from these, there is a LED control header that controls color, that final 4-pin fan header, and the audio header. There is also a LED connection here for the LEDs in the audio cover.

For the PCIe slots, MSI has gone with a layout conducive to three large PCIe devices, allowing for three dual-slot GPUs. That being said, all four of the shielded slots are powered by the CPU, giving up to four-way GPU when different sized coolers (or liquid cooling) are used. As a result users can go from x16/x16/x0/x8 to x8/x16/x8/x8 as required. In between all these are two PCIe 3.0 x1 slots for additional cards such as Wi-Fi, although PCI_E6 shares bandwidth with the U.2/M.2 arrangement, making it invalid when either of those two slots are in use.

The audio package is an enhanced Realtek ALC1150 audio solution, which is commonplace on motherboards of this price. This means, along with other upgrades, we get PCB separation of analog and digital signals, filter caps, an EM shield over the codec, extra plating on the audio jacks, and in this case, an extended shield over the audio section to assist with the aesthetic. This section also lights up as well. The audio solution makes use of the Nahimic software package, which we will go into in the software section.

On the rear panel, from left to right, we have a combination PS/2 port, two USB 2.0 ports, a BIOS reset button, four USB 3.0 ports in red (from a VIA VL805 USB 3.0 hub), the Intel I218-V network port, two more USB 2.0 ports, a USB 3.1-A port, a USB 3.1-C port (both from an ASMedia ASM1142 controller), and audio jacks with SPDIF output.

This board has 3-4 LED zones to control, from the audio, rear panel, main chipset, and power delivery. As we’ll explain later, there are a number of different ways to set the colors to take advantage of the RGB nature of the LED configuration.

    Great more rainbows, cuz nothing spells "pro" like rainbows do. IMO people already know that RGB LEDs implies they can change color, so rainbows aren't really necessary, unless trying to appeal to a specific and fairly narrow market niche. Reply

    Are you guys looking to update your review GPU?

    A GTX980 is seriously falling behind the times and will bottleneck a CPU in many titles even at 1080p.

    If a GTX 980 is a bottleneck for 1080p gaming, then I'm officially done with the PC Gaming Industry ... forever. Have fun playing games that look pretty and run crappy. Reply

    Oh no! a 2014 GPU is a bottleneck in the newest games in 2017?!? WHO WOUDDA THUNK?!?

    The 980 is a good gaming chip, but for benchmarks like this, it's been long known that there are better parts for the job. 980ti/1070 should be the minimum.

    Since the gaming PC is the only area where PC sales aren't slumping that niche might not be so small. You'd be amazed how many people dream of having a gaming system with the typical gaudy computer case, mandatory transparent side-panel, as many LEDs splashed around in every little component, the RGB-er the merrier, hopefully any kind of custom watercooling loop to show fluorescent tubing on top of everything else.

    It even says "Gaming Pro", not "Pro".

    Ian, are you sure about the $0.002 per HDMI connector thingy?

    It's probably not far off. When you get to quantities in the tens of thousands and up, stuff like that gets CHEAP. It's not $0.002 in final cost; production time and resources aren't free. Having an HDMI connector vs. not probably ends up being a difference of $0.10 (+/- $0.05). Folks that know electronics manufacturing better than I, please correct. Reply

    ddriver wasn't complaining about the RGB LEDs, but rather that to advertise them they put them in a rainbow configuration, he thinks that it should be obvious and so they shouldn't do it, unless they were trying to attract people who like rainbows.
    I don't agree with him, rainbow advertising material makes it clear that the LEDs are INDEPENDENTLY controlled.

    I don't think I agree with you. I'd say the best feature of customizable RGB lighting is that you can turn it off or just pick a suitable colour scheme. That way it doesn't matter what you want, the board will still appeal. I'm not big for the gaudy crap (I once bought an Alienware m14x R2 because of the massive discount and ran it with only the keyboard lights on an set to white the whole time), but it doesn't really bother me if the LEDs are there as long as I can turn it off. The reason you're seeing these everywhere is that they don't add very much cost to the bill of materials. Reply
  • ddriver - Monday, February 6, 2017 - link

    I don't think you got my point. I don't have a problem with customizable RGB LEDs, I was just pointing out that the rainbow showcasing really ruins the "pro" looks of the product. Reply
