Overclocking

Maximum overclock data was added to Performance graphs beginning with the nForce4 SLI roundup several months ago. The overclocking performance graphs should allow better comparison of the overclocking capabilities of tested boards. For more details on the specific overclocking abilities of a specific board, please refer to the Overclocking and Memory Stress Test section of individual board reviews. Since the nForce4 Ultra and nForce4 SLI are based on the same chipset, performance should be directly comparable. You may want to look back at the results in nForce4 SLI Roundup: Painful and Rewarding to see a broader range of overclocking performance.

Overclocking

When we benchmarked nF4-SLI boards several months ago, it was very early in the release cycle for nForce4 motherboards. We were surprised to see the large spread of overclocking results, but there was the explanation that the boards were new to market and we were testing immature technology. We are now several months down the road and the nForce4 Ultra chipset is everywhere in the market. Now, we have to wonder why there is such a huge spread in overclocking results with the nForce4 Ultra boards in this roundup. Names like Abit, which should be at the top of the OC game, barely reached 250 in our overclock tests. The enthusiast wannabes also generally performed extremely poorly.

It is almost like some board makers understand how to overclock nForce4 motherboards and others are still struggling. Two boards clearly stand out in overclocking in this roundup:the Epox 9NPA+ and the DFI LANParty UT nF4 Ultra-D. These two turned in bus overclocks more than 50% higher than the third placed motherboard, and they were also the top two in stock ratio overclocking.

    oh...final system will have 4-5 HDs, standard DVD reader/writer along with (most likely) a 6800Ultra or a X800XL...

    Anandtech did toy with a listening test a while back (I really don't remember much about it, other than the fact that they should have used Klipsch proMedia Ultra 5.1 speakers...)

    Maybe I missed this info in the article somehow, but could you provide the minimum/recommended PSU wattages for the motherboards? esp the DFI and the Epox. I have a Antec 400W Smartpower PSU right now, but read a few posts on newegg that this might not be enough? Hope I don't need to upgrade this too along with the mobo, cpu and gpu...

    I have a comment about audio -- a topic that most sites ignore.

    Shouldn't there be a blind listening test?


    i mean cpu utilization is fairly useless. If i am listening to mp3s i care more about the quality than cpu utilization.

    I stopped reading on page 4 upon discovering the round-up. No explanation needed...

    g33k -
    The DFI was more a control to demonstrate SLI and Ultra performance were the same other than SLI video. Drivers have updated and we retested everything on the DFI as a sanity check. We ran benchmarks and not a full review, but it was hard to ignore the excellent performance.

    There is also a comment in our Final Words that the MSI Ultra board should also be considered a winner, since the SLI version was a Gold Editors Choice in the SLI roundup, and the Ultra should perform the same.

    Along the same logic though, I'm curious as to why you chose to review the DFI Ultra-D when you reviewed the SLI version of this board earlier as well?.
  • g33k - Tuesday, July 5, 2005 - link

    Jeez, read Wesley's comments, he just answered why he did not review, the MSI board. It was already reviewed in the SLI roundup.

    "As you can see, none of the onboard audio solutions were quite as low in CPU utilization as the Creative SoundBlaster Live! Chip, which is used on the MSI K8N Neo4 SLI Platinum tested in the nForce4 SLI roundup."

    Since this is still nF4 we included components tested on all nForce4 boards. The Ultra version of the MSI, BTW, uses the Realtek ALC850 chipset and not the Sound Blaster Live!. The SB Live! is only used on the MSI SLI.
