ASRock X99 Extreme11 Motherboard Review – Quad X16 SLI/ Crossfire Gfx and 6.1GB/s Speeds

If you could load a motherboard with absolute killer features, what would you include?  Intel’s new X99 chipset opens the door a bit where, with the right X99 CPU, our PCIe lanes increase to 40 allowing us the leverage to stack our systems much more than we ever could have before.  Can you imagine a triple SLI/Crossfire graphics card layout where each is running at PCI-Express X16? How about adding another card and creating a quad graphics card config where each card is using 16 lanes?  Not many motherboard manufacturers reach for the stars with 16/16/16/16 but that doesn’t stop ASRock; two PLX PEX PCIe Gen 3 8747 bridges make this all possible.

What if we could look at storage?  We reviewed the ASRock Z87 Extreme11a/c motherboard and that board had 16 SAS/SATA Ports, along with a LSI SAS 3008 PCI Express 3.0, 8-port, 12Gb/s SAS and SATA I/O controller and LSI 3x24R expander; allowing us a 12Gbps SAS RAID or 16 SATA RAID configuration.  As much as we loved that set-up, we let ASRock know their inclusion of 2 x mSATA slots would have been easily topped with M.2, to which their Z97 release included an Ultra M.2 PCIe 3.0 X4 and M.2 PCIe 2.0 X4 slot.  Now look closely at the newest X99 Extreme 11.  This board is the board storage geeks dream of. Not only have we pushed our ports to 18 SATA ports of which four are once again capable of SAS 12Gbps RAID, but also, ASRock has implemented two Ultra M.2 PCIe 3.0 X3 and each is one day capable of seeing a high of 32GB/s transfer speed.  Better yet, why not RAID two Samsung 512GB XP941 M.2 X4 SSDs?

The X99 Extreme11 motherboard is ASRock’s new flagship motherboard and supports Intel i7 and Zeon 18-Core processors, based on the LGA 2011-3 socket.  Just as a bit of a reminder, the former 2011 based Intel processors will not fit into this socket.  It is capable of accommodating up to 8 x DDR4 3200+(OC) RAM chips for a total of 128GB and supports DDR4 ECC UDIMM/RDIMM memory.  It contains 5 x PCIe 3.0 x16 slots, along with two PLX 8747 bridges that make 4-way X16 SLI and CrossfireX possible.

With respect to motherboard input, the ASRock X99 Extreme11 contains power and reset switches with LED, along with two PCIe power connectors on the board itself.  Its IO panel contains 4 x SATA 2.0 USB, a PS/2 keyboard/mouse input, 4 x USB 3.0, 2 x Intel Gigabit Ethernet, as well as the typical audio ports.  Something we learned with this board, as installation of Windows 8.1 was not possible with an Ethernet connection (drivers required), was that Win 8.1 doesn’t force a MS e-mail account on installation, speeding things up considerably. Who knew?

Motherboard build is something else that ASRock has paid close attention to and this is obvious in the ASRock Super Alloy package that includes very prominent XXL Aluminum Alloy Heatsinks, a Premium 60A Power Choke, a Premium Memory Alloy Choke, Ultra Dual-N MOSFET, along with Nichocon 12K Platinum Caps on a sapphire black PCB. All three heatsinks are connected by metal piping and you might notice the largest has active fan cooling.  This particular heatsink encompasses the X99 chipset, LSI SAS 3008 controller, along with the two PLX PEX 8747 chips and still gets quite warm.  Although not in any way a deal breaker, this fan is not as silent as we might like, sounds like a jet engine on system boot and is audible slightly above other fans in our system.

Something we didn’t expect was a very attractive black ‘ASRock Extreme’ embossed bag that contained all connectors and cabling, along with a manual, Quick Start Guide and IO Panel face.  We found the exterior packaging very detailed and well laid out.

Last but not least, pricing had not been set for the X99 Extreme11 at the time of this report, but consider that it most likely will be commensurate with the components contained…a bit pricey.

    This board is heavy on the “drool” factor!!

    It doesn’t have 4×16 SLI. That is a marketing ploy/lie (at least in that context). Those PLX chips are useless in that scenario. They are only useful when your PCI-E cards aren’t all going to be in use at the same time. They are much more useful for storage than graphics.

      You might want to take a look at the ASRock video that tests it. Perhaps we should have posted it.

      It’s worth mentioning that with graphics 4×16 PCI-E 3.0 doesn’t really make much of a difference anyway, as graphics cards won’t use all of the bandwidth, especially when you consider how poorly 4-way SLI/CrossFireX scales in comparison to 2, or even 3-way.

      The 4×16 is absolutely much more of a factor in terms of storage than graphics, but that has little do to with whether or not the board can actually utilize the function across four graphics cards simultaneously .

    compared to striker 2 extreme this is nothing

    MB Manual:

    It will be great next year when M.2 Interfaces are more common and even better capable.

    ASUS’s M.2 Interface seems to only support ONE short Card but the X99 Extreme11 accepts 2 Cards from 3 to 11 cm long. I see a new RACE to support longer Cards in greater quantities.

    It would be neat to see each of the X99 Extreme11’s M.2 Ports double stacked, so we could get 4 Cards on the MB. Hang a couple next to each rack of DIMMs for a total of 6 Ports.

    ASUS claims they have a RAMDisk that is 20x times faster than SSD, (like on their Maximus VII Formula MB), now we need to work on getting 10G Ethernet on these MBs (it goes without saying we want 10G Ethernet in our homes, at a low cost – Hint: Local Cable Provider). Then the last battle remaining is efficient 4-Way scaling.

    More than some people need, here we come !

    I’d really like to see Les, do a test on the Asus Maximus Hero VI with the Intel DC P3700

    Asus or anyone please send Les the new Asus x99 Rampage V Extreme Motherboard so he can perform a review on it

    does this motherboard support install windows on a M.2 RAID 0 configuration?

    Thank you for the review.
    I need a sustained sequential write of 3.2GB/s on a raid 0 with 8 Samsung SSD 850 Pro 1TB.
    Do you think this board can help me?
    thanks !
