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

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

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.

Value seekers are definitely appreciating the fact that Intel launched its most advanced desktop CPU technology in the mainstream space first. Meanwhile, enthusiasts with more exacting platform needs can breathe a sigh of relief now that X79 Express supports the same architecture at the high-end. If you haven't yet read about it, check out Intel Core i7-3960X Review: Sandy Bridge-E And X79 Express.

Perhaps we should replace the word “high” with “extreme,” however, since the cheapest LGA 2011-based CPU currently sells for about $600 bucks. It only stands, then, that exorbitant CPU prices would give way to expensive platforms. Fortunately, the connectivity enabled by Sandy Bridge-E and X79 Express is also more expansive than anything ever seen before from Intel.

A CPU-based quad-channel memory controller and 40 CPU-based third-gen PCIe lanes with built-in four-way SLI/CrossFireX support make X79 platforms stand above their Z68 siblings in the desktop segment, and we believe that anyone with the money for either a $600 or $1000 processor will also have the cash to spend on the best possible platform to support it. And yet, our announcement that the first X79 motherboard round-up would focus on flagship models to match Intel's introduction was met with a collective “What?!” by most manufacturers.

How could we expect the best products so soon after launch? With a little more time, a lot of vendors expected they could deliver a true masterpiece. But we were just as baffled by their responses, since most companies we talked to earlier in the year started X79-based motherboard development efforts last spring.

Most companies let us know that their flagship models were not finished, and that claim stood even after we announced a one-week grace period for late submissions. Imagine our surprise when several of those supposedly unfinished motherboards landed on Newegg before their manufacturers were willing to let them compete! What we ended up with was an interesting collection of premium (albeit non-flagship) models with high-end feature sets that help justify decidedly enthusiast-oriented prices.

    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 :)

    I am running 4.4GHz on 1.2V Revision C1 ASRock Extreme4 Bios 1.50. At 1.4V i can run 5.0Ghz but i don't have good enough cooler so i reverted back to 4.4.

    "This list of high end x79 boards seems top be missing the rampage iv extreme."

    I was wondering the same thing. I was about to purchase the rampage iv extreme then I saw this story. I was hoping to see it compaired with these boards. But, maybe it's in a league of its own.

    If the average Joe can only expect 4.4GHz with x79 I would guess many will stick with easy to reach 4.7GHz 2600K on air.

    It uses the same chipset and Asus doesn't differentiate integrated components on a per board testing basis. It will almost assuredly perform at the same level the other boards do, it just has a brand name unscaled cost and different tweak software.

    In general, the entire x79 platform seems poorly executed to me. For having over twice the transistor count of a Sandy Bridge chip, the E line does not have performance to match that much of a die size increase, coupled with the base TDP being as high as it is, I would expect many more cores or much higher clocks out of them, especially considering they don't waste die space on integrated graphics.

    That and the motherboards to go with the platform are all extremely overpriced. It is understandable that a new socket type has a lot of manufacturing overhead, and 4 channel RAM is magnitudes more complicated circuitry than dual channel, and having the PCI lanes support almost three times the bandwidth and channels is costly. But it isn't triple the price of a reasonable z68 motherboard costly.

    $320 buys a Core-i5 and a decent mobo, or a Phenom II X4, decent mobo, and RAM; either of which will fully meet the processing needs of at least 95% of computer users.
    The CPU is worse; for a total buy-in of $920+ (adds the cost of an i7-3930K) you can build a very nice system indeed, as the $1K SBM articles clearly show.
    In today's economic climate, X79 may make sense for only a very few people. I'm not one of them, and while there's certainly no harm in reading about it, I doubt many regular Tom's readers are either.

    Only Intel can sell $320 plus motherboards with no lifespan.....remember X58.......X79 is supposed to have a shorter life than X58.

    Suckers!! haha

    Uhm... with 1.35V I can hit 4.8GHz on my 2500k... which is actually quite typical. Most mid range p67 and z68 motherboards will allow for about the same OC with the 2500k / 2600k.

    Which makes me wonder. If a 2600K can normally hit 4.8GHz on modest air cooling, and an i7 3960X is going to typically max out at around 4.4GHz with the same Vcore and cooling.... that's a 10% higher clock speed on the 2600K. The 3960X should perform about 20% faster at the same speed.... meaning... the difference is going to be what? 10% in favor of the 3960X.

    So, 10% more performance for about 3 times the cost.

    For anything but professional workstations, it seems that X79 doesn't make a whole lot of sense.

    I don't get all the hype with this LGA 2011, seriously. Actually the motherboards are awesome, you get PCIE 3.0 and stuff, but the cpus are sooooo hyped. I see minimal improvements in speed, not to mention in games those few frames per seconds are ridiculous for a cpu that costs twice and more.
    Next year i'm getting a new LGA 2011 mobo and an "old" 2600K and spare some cash for a better GPU.
    Greedy bastards...
