Ultimate X79? Five $320+ LGA 2011 Motherboards, Reviewed

Our flagship motherboard comparison announcement was answered with an interesting selection of models, along with a bunch of “not ready yet” responses. Today we examine a few samples from companies bold enough to step up to the plate during launch week.

Which High-End X79 Motherboard Is Best?

Our highest-priced X79 motherboard comparison was intended to highlight the feature sets of over-the-top products, with price being used only as a tiebreaker should any two products emerge as best-of-the-best. So, where are the flagship products?

It appears that everyone was caught off-guard by minor changes between the C0-stepping processors they received during the summer and C1-stepping products that Intel used for the launch. Of the participants, it appears Asus had the quickest firmware turnaround. Everyone knew that we'd use C1 silicon to test, and it makes complete sense that they might not want firmware teething issues to affect their highest-priced parts.

Though we had a reasonably broad selection of candidates, firmware issues left us considering only the two products that came closest to our expectations. Asus’ P9X79 WS had the best performance, best overclocking, lowest power consumption, and greatest number of expansion slots. Meanwhile its P9X79 Deluxe followed closely behind the WS version, but added a bunch of lifestyle-oriented features like Bluetooth, Wi-Fi, and a greater number of USB 3.0 rear-panel ports (even though several ports share bandwidth). The added features are surely worth a little more than the miniscule differences in performance. And yet both boards are priced the same.

Torn between the best board and the board with the most to offer, we decided to give both products our “Approved” award and let each buyer independently determine which of these is more deserving of the ultimate honor: a purchase.

    Something is wrong with your ASRock Extreme 9 testing. You article states that you used BIOS 1.40 however first release for this Motherboard was 1.60 and they also recently released 1.70. Bios 1.40 is for ASRock Extreme 4 which i own as well. Again in mean time they updated BIOS for ASRock Extreme 4 to version 1.50 which greatly improves overclocking. I have C1 and i am hitting 4.4Ghz easily. (1.50 BIOS ASRock Extreme 4).

    You might want re check the facts.

    Thanks.

    lradunovic77Something is wrong ...You might want re check the facts.Please do verify the facts beginning with the first X79 Extreme9 UEFI screenshot on page 3, showing version P 1.40 . The latest public firmware was downloaded for every motherboard on November 18, which is before ASRock says its P1.60 was even published. And, if you check Newegg, you'll find that Newegg was actually selling the X79 Extreme9 before firmware P1.60 was published.

    How could that happen? ASRock has repeatedly removed previous BIOS versions from its website and labeled the replacement as the initial release.

    This review was published after many hours of collaboration with ASRock, and some of the problems with this specific CPU are further detailed in the overclocking section. ASRock acknowledged the problem exists with a portion of the C1 CPU supply and has begun issuing patched BIOS to fix the multiplier issue, according to ASRock engineer William Yu.

    Not to mention that they didnt say they couldnt hit 4.4ghz, they just stated they didnt get that high without going beyond 1.35v

    Kinda wish we got to see a MAX overclock for air before temps got out of control =P
    But then you get various coolers involved... yada yada... but PLEASE anyway

    This was a fun article to read. I wanted to quote a few bits here and there just to point out I enjoyed the humor in it, but that would have been a lot of quotes. It's subtle, tasteful way to add personality to the piece.

    I had to comment on something. I can't really comment on the hardware as its so enthusiast and SB-E is well beyond my needs. I can't comment too much on the bios because I still barely understand mine, but I am seeing the trend that it might be best to stick with what you know, or risk having to translate the various names/definitions of settings across different products. I'm not that smart nor that patient. I liked the comment on the 6.00...lol... %! I never would have thought. I think that just deciphered half of my bios options, thanks. /wink

  • In the comparison table on the ASUS : "6 (x16/x0/x4/x16/x4/x0 or x8/x8/x4/x8/x84/x8)" -- x84 seems somewhat unlikely ;-)

    Not surprised both Asus boards came out on top performance wise, on most of these mobo roundups they usually do.

    Without trying to sound critical, wouldn't it be prudent to test SLI scaling on these enthusiast boards? 1, 2, and 3 way SLI, extra PCI-E bandwidth is one of the main reason why people even bother splashing out the extra cash on these chipsets. (Aside from the extra epeen++)

    Just sayin'

    AsRock has the better looking MB by far...

    Question does tht little fan on the motherboard get loud? If it does that would be a deal breaker for me

    the problem with testing mobos is that they all have the same core (in this case the x79) which is what determines the raw speed of the system and busses, so they are all pretty well bunched together with no possibility of seeing any real world difference between boards. The things that differentiate the boards is in their feature sets, and as they are all rather different there is no proper way to test them against one another. Add to that the fact that these are all brand new boards which will see improvements with new UEFI releases, and there is really no way to pick a clear winner.

    On a side note I would love to see how these boards look assembled :)
