Board Features

Having gone through and generated the following table for the M8E, I find it mildly amusing, especially as I’ve just put a $120 motherboard on the test bed here. By comparison, instead of most of the sections saying none/blank, when dealing with a $500 motherboard everything is filled up. More SATA ports, more features and more room to add things means that a halo motherboard has to be the Rambo of a PC build.

The big active features for ASUS come in at the 3T3R tri-stream WiFi, an ESS DAC, Thunderbolt 3 support via Intel’s Alpine Ridge controller, a total of four USB 3.1 ports split between the Alpine Ridge and ASMedia’s ASM1142 controller and then the sheer amount of switches and buttons onboard for power users to configure their experience. The OC Panel header for both power users and extreme overclockers comes in handy with the bundled OC Panel.

Using the chipset diagram, it shows a slightly more complex picture. Everything on the left side is what we would expect, including the complex way that x8/x4/x4 is implemented on the PCIe side, although it is worth noting that the HDMI 1.4b port is provided through the Alpine Ridge controller rather than the CPU. I would assume this is actually just a bypass to help with routing though it may suggest that the TB3 controller cannot use HDMI when the DisplayPort functionality is in use. I’ll be synchronizing with ASUS on this.

On the right hand side we see that two of the SATA ports (4/5) share bandwidth with the PCIe x4 slot at the bottom of the board. When SATA devices are connected, the PCIe slot will reduce to x2 bandwidth. Also on the right hand side is an ASM1187 controller, which looks like a 6-port PCIe switch. Taking one PCIe lane in, it gives an output to five ports which include the two ASMedia SATA ports, two of the rear USB 3.0 ports, the Wi-Fi module and the two PCIe x1 slots. However, unless one of the PCIe x1 slots is using full bandwidth, I doubt it is much of an issue, and if anything it would be a latency issue. But it might also explain why we could not get proper USB 3.0 speed results through the ASMedia controller.

In The Box

We get the following:

User Manual
Driver DVD
Rear IO Shield
OC Panel plus 5.25-inch Bay
Fan Extension Board
Wi-Fi Antenna
Thermal Probes
CPU Installation tool
Eight SATA Cables
ASUS ROG Stickers
ASUS ROG Door Handle Sign
Flexi-CrossFire Connector
Flexi-SLI Connector

At $500 and being part of the ROG brand it means the in-box goodies should be plentiful. The star of the pack is the OC Panel, used by extreme overclockers to make adjustments on the fly or system builders to monitor fan speeds/temperatures with one-button overclocks.

We’ve discussed the OC Panel at length before, and this is the third generation with the same model, featuring more fan headers, VGA Hotplug and extra switches for system control.

Also in the box are a set of thermal probes to use on the extra thermal probe headers on the motherboard, giving the ASUS software extra read points for temperature if the user wants to monitor specific zones in their build. The CPU installation tool is there to help new build users put the processor in the motherboard, although I didn’t find much use for it (I’ve never dropped a CPU in a socket yet…). It is interesting to see so many SATA cables in the box though, however these are mostly likely bought in bulk and minimal cost to a board like this.

ASUS also sells the Maximus VIII Extreme/Assembly, which comes with a custom audio output dock as well as a Tahuti Networks based 10 gigabit Ethernet card using RJ-45.

    $500 for +1% fps? Sounds like a really smart buy. Reply

    No... that's not why you buy this board... Reply

    Same as $700 phones when a $200 or even $30 handset does the job 95% as well... Reply

    But if the phone is gold plated and encrusted with diamonds it does the job A LOT better. Now I dare you to name the job ;) Reply

    Given that this ASUS board has no PLX chip, might as well get the ASRock Z170 OC Formula instead. It doesnt have the Alpine Ridge / TB3, or the 3x3 Wifi. But then few people use such things anyhow.

    It seems no review of the OC Formula here because at the time it wasnt out yet, and also because you reviewed the ASROCK Extreme 11 instead... yet the OCF is a great board.

    ... Extreme 7+ was what I meant to say at the end there. Reply
  • extide - Friday, April 8, 2016 - link

    Yeah the Asrock Z170 Extreme 7+ is my fav Z170 board out right now. Dual (good) nic's, 3 m.2, no other extra BS, reasonable price, etc etc. Reply

    There are no new astons for under 100K, not USD. You might find a stripped one for less than 100K British pound, but since you referenced USD thats a no go. Reply

    Ok... and now somebody could make a mobo for me:

    2x U.2 NVMe + 6x SATA-3 (able to run all 8 ports simultaneously, SATA-3 needs to be able to run RAID-5 or 5e)
    No wifi, no integrated sound (waste of cash for me)
    integrated Intel NIC (1Gbps+)
    2+ USB 3.1 type C ports
    6 USB type A ports (2 of those USB3.0)
    4x DDR4
    1xDisplayPort, 1xHDMI 2.0
    3-4 PWM for fans (ideally at least one powerful enough to drive water pump)
    2x PCIe 16x (can be in 8x/8x mode)
    1x PCIe 4x
    1-2x PCIe 1x (one should be sound card low latency friendly)
    LGA 1151

    That would fit exactly my requirements for currently ideal mobo.

    Best bet is the ASRock Z170 Extreme 7 -- it has 3x M.2 ports which you can get the adapters and convert them to U.2 -- there are no boards out with more than one U.2 built in right now.

    Also, can't believe there is SATAe on this board. WHEN WILL IT DIE!!
