Seven $260-$320 X79 Express Motherboards, Reviewed

X79 Extreme6/GB UEFI

This editor’s second C1-stepping Core i7-3960X has the same supposedly-rare issue as his first, preventing Windows 7 from loading when the multiplier is increased beyond 36x on most motherboards. We spent days with ASRock trying to diagnose the issue. So far, though, only one manufacturer has a workaround.

As a result, the highest six-core overclock was achieved using 36 x 130 MHz. ASRock automatically implements the chipset’s 1.25x BCLK to PCH multiplier anywhere between 113 and 149 MHz. So, the chipset was barely beyond its specification as we shot the CPU to an impressive 4.68 GHz. Default Turbo Boost modes were disabled, since allowing the chip to jump to 39x with two cores active resulted in 5.07 GHz, and that wasn't a stable frequency.

Ratios, power limits, and frequency controls are followed by three overclocking profile set points on ASRock’s OC Tweaker main menu.

Found in a separate submenu, voltage controls include core, CSA, VTT, PLL, DRAM, and PCH. That covers just about everything that most overclockers need.

The X79 Extreme6/GB has both primary and secondary memory timing controls, without the inconvenient double-setting change found on earlier ASRock boards.

    Quick coment on looks only (I know its specs that count not looks but oh well)
    ASRock X79 Extreme6/GB - very nice all black looks better than gigabytes atempt
    Asus P9X79 Pro - new baby blue they use on all the boards... not for me
    ECS X79R-AX - looks like my old pentium 2 board with the white slots
    Foxconn Quantumian-1 - i like i like gives a feeling of the ROG ASUS boards
    Gigabyte X79-UD3 - rip of from the ASRock X79 Extreme6/GB (lol) plus the southbridge heatsink looks old fasion and ugly.
    Intel DX79SI - now this board for me looks good actualy more than good looks the best :) must be the scull lol
    MSI X79A-GD65 8D - also very nice love the blue + Black.

    If you have one of the boards and i insulted it, wasnt the intention, just my view of the board>

    Great descriptive article.

    One thing I'm not sure of is the acceptance and actual usage of eSATA. While practical at some level, is anyone actually using this MB feature or is this one of those things the MB producers can skip out on like parallel and serial ports? I'm not sure enthusiasts are all that into using their eSATA ports?

    Personally, I think this is one of those money saving opportunities MB producers should consider.

    After the X58 anal pounding, you would be a moron to buy a X79. It's life is predicted to be even shorter than X58.

    Actualy i agree with you ubercake, i have never used my E-sata, and with usb 3.0 out doubt anyone still uses E-sata if they have before.
