More than any other manufacturer, Gigabyte loads their premium boards with every feature that you can think of, and then some. The K8NSNXP-939 certainly follows in that tradition as a member of the 6-Dual Deluxe family. Gigabyte has also developed a reputation of providing some of the widest ranges of adjustments to allow the Computer Enthusiast to squeeze the last bit of performance from their board, CPU, and memory, and the 939 continues that tradition.

The one glaring area that continues to plague recent Gigabyte designs is the extremely limited range of memory voltage adjustments. In this case, memory can be adjusted to +.2V and that's it. After seeing this complaint voiced in review after review, you would think that Gigabyte would seriously consider a wider range of vDIMM adjustments. Offsetting the limited vDIMM is a decent range of CPU voltage adjustments and the excellent addition of HyperTransport voltage options.



The most notable features of the K8NSNXP-939 include high-speed 1394B Firewire for firewire fanciers, Dual LAN, extensive RAID capabilities spanning SATA and IDE drives, and 8-channel audio with UAJ. We were also impressed with the updated design of the DPS 6-phase power module. It now sits lower on the board and our past complaints that the DPS impeded air flow are now history in the new design.

Layout of the Gigabyte 939 is nearly ideal, with the added step that even the SATA connectors are in locations that will not interfere with the largest PCI and AGP cards. The unique AGP EZ-Fix slot is also proving to be very useful, especially when using top-line 2-slot video cards. Anyone who has tried to remove a 6800 Ultra from a common rear-lever AGP slot probably cursed the designer and maybe broke the lever trying to find it under 2 slots of video card in a sea of capacitors. That's not to say EZ-Fix is that easy with a 2-slot card, but at least you have a fighting chance of removing the card. Gigabyte also kept capacitors away from the AGP slot.

    "Our FX53 topped out at about 3.59 GHz on the ECS KV2, which is slightly below the 3.6+ achieved on the top 939 boards."

    Is this ECS a P4 board? :P

    This was a great article. I agree with other readers, CnQ should definately have been tested, as well as audio and IDE subsystems.

    btw Wesley, will there be reviews of KT880 socket A mobos in the future?

    Just a few comments. It's a little (*little* mind you) unfair to compare FX-53 to P4 560, given the price advantage of the P4. Then again, comparing it to the P4EE is a little unfair in the other direction. It might have been nice to include one or two other systems in the benchmarks, though, like a 3400+. Sure, we can cross-reference other articles, but if you have all the data already it would be a lot cleaner. I'm especially interested in seeing AutoGK benchmarks with the "lesser" Athlon 64 processors (3500+ and 3400+ would be good, or maybe even 3200+ - not everyone has $400+ to spend on a CPU!)

    Of course, while it might be less fair to Intel, I would like to get AutoGK numbers using Xvid as well. That's how I use it, as I feel the quality is a little better than DivX. Oh, and while you state that you used 2-pass encoding, what was the target resolution? 640x360, or 720x408, or something else? And did you specify a target size, or was it on unlimited quality? All those are important questions, I think.

    One final request: I truly appreciate the memory stress testing benchmarks. However, I would like it taken a little further. All of the boards claim that they can support up to 4 GB of RAM. I would love to see some tests showing this configuration. After all, 64-bits is really about breaking that memory barrier. Even if the boards need to run 4x1GB at DDR266 or DDR333, it would be good to know. (Too bad there simply aren't many good 1 GB DIMMs available yet.)

    #14 & #20 - Perhaps tests with the X800 XT on nF3 compared to the 6800 Ultra will at least shed a little light on where the efficiencies lie - in the nF3/nV Video combo or in the nF3 itself.

    #16 - We will make an effort to talk a bit more about Cool'n'Quiet in individual board reviews, but in a roundup like this it is difficult to explore that level of detail, and still hold the article length to anthing you might want to read. We try to do more with features in individual reviews.

    #19 - We report the full range of vCore in our board charts for people like you who are interested in umdervolting. If you notice some boards begin vCore at default, while others make a wide undervolt range available as well as overvolt. We try to report this range as accurately as possible for this reason.

    Wesley, very interesting numbers. Halo is supposedly limited by some inefficient DX9 layers/commands, so I at first thought maybe nV had somehow optimized or bypassed some DX9 calls. The office and Content Creation benchmarks advantage is more puzzling, though. Could nV's performance edge be the result of some intelligent caching or either the HD or the CPU?

    Testing an X800 for reference is a good idea for Halo. Just be sure to retest the office and Content Creation suites, too, as the performance boost there is equally curious, IMO.

    I found one typo, on the system specs page. It's Wolfenstein: Enemy Territory, not Wolfenstein: Enemy Within. :)

    Sure there's Cool'n'Quiet, but how about adding manual undervolting capabilities to the review? A lot of mobos only allow upping the vcore, but undervolting is a great tool for creating a truely cool and quiet system without losing performance.

    Love that FX53 and the MSI K8N Neo2 together. Sure is purdy nice!! ;) But must...hold...out...until...price..drops...some..more.. ;o)
    Great article BTW!

    I miss information about Cool'n'Quiet. It's a shame that anandtech.com only is insterested in overclocking and speed.
  • esSJae - Tuesday, July 20, 2004 - link

    Nice, another article touting the non-existent MSI K8N Neo2.

    Sure, you can go to MSI's Taiwan site and download the manual and BIOS, but doesn't seem to be much point in that.

    "We never expected the nVidia nForce3-250 Ultra to be a better performer in Winstone benchmarks than the VIA K8T800 PRO. However, both the nF3-250 boards are outperforming the VIA boards by a significant percentage. Since the nVidia 6800 Ultra video card was used for all benchmarking in the roundup, we plan to verify these results with an ATI X800 XT as soon as that board is available to the Motherboard Lab for testing"

    Is this to determine if it's a result of forceware opts that is responsible for the difference observed?
