X58 In 2010: Four LGA 1366 Boards With USB 3.0 And SATA 6Gb/s


Here’s a quick comparison chart of the available BIOS settings each motherboard provides to assist overclocking and related performance optimizations.

Though some boards have broader adjustments than others, we normally reach the limits of our hardware at BIOS settings far below the maximum. Part of that is due to a very early C0 stepping CPU core that we’ve used consistently to provide comparable overclocking data for all of our X58 motherboard roundups.

The motherboards with 16-phase and 24-phase CPU power regulators push our old CPU beyond 4.1 GHz, while those with eight-phase units settle under that mark.

Asus takes the lead in maximum base clock by a mere 1 MHz. Both $200 motherboards reach the same speed, but ASRock takes the lead alphabetically.

Asus also takes the lead in memory speed. Greater numbers might have been achieved using Gulftown’s improved memory controller.

    First Intel punishes me by not releasing a proper 32nm 920 replacement for the 1366, and then Tom's publishes this article only days after I purchase components for yet another 1366 build.

    I must be a BYOPC masochist.

    Nice to see that mobo makers aren't charging too much of a premium for USB 3.0 and SATA-6. On the other hand, what an embarrassing for ASRock just as I thought they were getting out the shadow of ASUS.

    I would have liked to see those new ports put to use on these boards...

    I very recently decided to take the plunge in an i7-based build, and I chose the UD3R for it. I couldn't be happier - this little monster pushes my i7 to 4ghz stable on stock vcore.

    One thing I haven't seen anywhere though, but would like to, is the overclocking variance added through differing ram capacities. Even though I reached 4ghz on stock vcore, I had to push my QPI to 1.35 to keep the system stable with 6 modules installed. With 4 modules, this was reduced to 1.28, and with 3 it was around 1.24 and with only 2 I could run the QPI volts at 1.2.

    Perhaps an idea for an in-depth article at some point in the future Toms?

    Thank you TS. I think you may have built and benched my new computer. I see you still chose the 920 over the 930. Even before reading this article, I had my eyes on the UD3R because of the price and the decent features, save the sound card. However because of this article, I am going to reserve this mb and start building a newbie!

    The next step would be to see how these boards stack up using 6 cores and letting people know what power with 6 cores means using a 1 & a half year old motherboard. Although knowing that 6 cores, USB3.0 and SATA 6.0gb are a long way from being standard, it is by no means premature to have this board as one knows that they will be paying and buying for the long haul! The smartest ones do, and seeing as you guys chose the best parts for the price in terms of quality/performance, the UD3 is a perfect fit for a 5850 or maybe 2!

    You should send this article to someone at Intel and maybe they will want to soon follow the way of USB3.0 for their vanilla board! I guess these builds are the new standard for high end or borderline excellent.

    An error/typo in the table page 2?
    The table claims Asus P6X58D-E have Chipset S-ata 6 x SATA 6.0 Gb/s
    Should probably be 6 x SATA 3.0 Gb/s...

    At first quick look at the picture I almost fell from my chair... a quad processor MB, but then I realized Tom had problems squeezing the MBs in the pic.

    zipzoomflyhighAnother X58 reviews. Just what we all wanted. NOT.Yeh, X58 is obviously exceeds your needs but there hasn't been much news on the Via Apollo Pro front.

    i'd been planning on a p55 chipset + i5 750... now i'm thinking of i7 930 + gigabyte ud3r
