Gigabyte GV-N580SO-15I Super Overclock

Four Overclocked GeForce GTX 580 Cards, Rounded Up
By

We've reviewed a handful of cards from Gigabyte's Super Overclock series, and we've yet to be disappointed by one (though we did recently encounter a hiccup with a Windforce-equipped GeForce GTX 560 Ti that kept overheating in Tom's Graphics Card Guide: 32 Mid-Range Cards Benchmarked). Even still, we have high expectations of the GV-N580SO-15I. It comes from the company sporting 855/1710 MHz core and shader clocks, along with 1536 MB of 1025 MHz GDDR5 memory, making it the highest-clocked product in our roundup.

The Windforce 3x cooler is similar to what we've seen from Gigabyte's high-end line, with three 80 mm axial fans. Two 8 mm heat pipes work in conjunction with a vapor chamber, resulting in excellent noise and temperature characteristics, as we’ll see in the benchmarks. We also like that everything fits comfortably within a dual-slot form-factor. At 11.4” x 5.7” x 1.8”, the card is slightly longer than Nvidia's reference GeForce GTX 580, but not by much.

The sample we were sent didn't come with the retail package's accessories. But according to Newegg, it should have included an HDMI mini-to-HDMI cable, Molex-to-six-pin PCIe and Molex-to-eight-pin PCIe power cables, a DVI-to-VGA converter, a driver CD, and a manual. It would have been nice to see some value-added software accompanying this high-end product; however, Gigabyte sticks to the basics.

Gigabyte guarantees its card for three years, which is better than the industry average one- or two-year term.

The card is equipped with two dual-link DVI outputs and a single HDMI mini output, identical to the reference GeForce GTX 580 we tested at launch. Under the hood, however, Gigabyte claims it uses its GPU Gauntlet binning process to pick the GF110 GPUs most receptive to overclocking.

We found the GV-N580SO-15I selling on Newegg for $535. That's about $55 more than most reference GeForce GTX 580 models, and quite a bit cheaper than the $750 GeForce GTX 590 (assuming you can even find one for sale).

Overclocking

Gigabyte includes its OC Guru software with this card, which is able to increase operating frequencies and alter GPU/memory voltages. It’s rare enough to find a manufacturer willing to expose GPU voltage modifications, but control over memory voltage is almost unheard of.

Initially, we tried to push an even higher overclock by increasing the card's fan speed to maximum and pushing the clocks as high as they'd stably go in FurMark. We increased the GPU and memory voltages from their stock settings of 1.06/1.59 V to the highest 1.161/1.695 V the utility would allow. It's worth nothing, though, that the GeForce GTX 580 incorporates circuitry to circumvent the unrealistic workloads applied by "power bugs" like FurMark. So, while we were able to hit a 970 MHz core clock and a 1090 MHz memory setting, it wasn't surprising that the GV-N580SO-15I wouldn't run at those speeds in actual games.

Unfortunately, it would crash during multi-run Crysis 2 benchmarking sessions, compelling us to bring the board down to a more grounded 930 MHz GPU clock and 1050 MHz memory frequency. Even at those elevated settings, though, the card continued to run quietly.

    Conclusion: A high-end overclocked gpu is a waste of money.

    Great article. Some ASUS boards would be nice on a next round up. And also that MARS card, with two GTX 580 in one board.

    +1 to include a ASUS DCII card.
    reason for MSI's faster performance : faster memory?

    The Zotac AMP card looks like it was designed with 1939 Germany in mind.

    What I don't understand is why you did not use the MSI lighting Extreme with an 832 core clock it would be a better contender in your shoot out here than the twin razor since your using the Zotac 3GB version. Does not really make since when you think of overclocked GTX 580 to leave that card out.

    Two GTX570s cost only $580. It is a way better option than an overclocked GTX580 imo.

    more memory is very handy for gpu based renderer like Mentalray's iray of Chaos group vray RT and it may be better chose over many nvidia quadro card.

    +2 for the ASUS DC cards, they should have had one of those models in the line-up.
    though there is a triple slot 580 from ASUS that should also be included.
    with all the talk on how the 590 is the 'flagship' card or the 'meat and potatoes',
    it's the 580 that really brings home the bacon..

    they return them. Anyone else want to see a sparkle 590 vs 6870 in triple screen performance

    well would need 6970 x2 card but even then would be cheaper

    Nice article. Maybe you'll get to play with PNY's new GTX 580 soon. Apparently they copied the corsair H50 idea and applied it to a GTX 580. Yep, a closed loop water-cooling setup on a 580. They boast some impressive overclocks. I wouldn't know where to mount the damned thing as I already have a H50. They also have another model that includes a block for the CPU as well. I'd hate to cool a cpu and a gpu with a single 120mm radiator, but that's what they offer. :S

    zotac looks wicked as always. i'll buy that for the looks alone, the performance/price balance makes it a hell lot sweeter :D

    I wish Asus ROG 580 wasn't 3 slots =/

    With a 3 slot video card, does that pretty much rule out 3-way sli?

    man that's gonna be hard...
    I do not think that it can be done, not even on this board..
    http://www.newegg.com/Product/Product.aspx?Item=N82E16813188092
    so I say it does rule 3-way out, FOR NOW..:D

    Poor Sparkle. They have the loudest cooler with the lowest power draw.

    But clearly, the MSI N580GTX was the strongest card in this round up. Gigabyte's Ultra Durable VGA GTX 580 did well in all the tests.
