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.

    "So ECS, Foxconn, Biostar - we can only suggest that you need to add features and performance that will make an AMD user want to buy your boards. "

    Why u think's ECS is bad ???

    From your benchmark, ECS is not too bad, their ranking in the middle until top1.

    Sorry, if myenglish is so bad.

    Page 1: "There are no performance differences in the SLI and Ultra chipsets, or even the base nForce4 for that matter. These chipsets differ only in which features are available to the buyer - but they beat with the same heart."

    I thought the base nForce4 had a 800MHz HT where as the Ultra and SLI have 1GHz. Is that not correct?

    For PSU requirements read the mfg websites. Especially the DFI comes with explicit requirements.

    480W 24pin ATX 2.0+ PSU and from experiance Id have to say that U want a 1st tier PSU on top of that. Anecdotal advices that its possible to run a DFI SLI set up overclocked from a 350W PSU exists but fact remains that a good solid 500W+ ATX 2.0+ PSU will help U with stability.

    What I want to ask: does the processor works with four DS DIMMS at 1T command rate at lower frequency? By what you say (that 2T command rate is much slower than 1T command rate), then 1T command rate at 333MHz would be faster than 2T command rate at 400MHz.

    I love the look of that Epox board. Pity noone imports Epox products into New Zealand any more.

    Ermm.. It's "Marvell". With two l's.

    I think that you must have a bad example of the ABIT. A no. of other sites (HardOCP, Hexus etc.) have all been over 300 ref. clock with it.
    Not to mention that there is also now the non-Fatality AN8 Ultra which is cheaper & yet has better sound & 3.55Vdimm instead of 2.8V on the Fatality ...

    I think the Neo4 should've been included even though it was in the SLI test. Same with the Asus board. Those are really important boards. I'm sure if you add up the Asus and MSI users they would outnumber Biostar + Foxconn + Chaintech + ECS. Iono. just my 2 cents. I dont want to go look at the SLI review and then compare it to this review to see other boards and do a mental benchmark merge to get hte relative performance.

    You know what we should make? We should make the uber super chart system. Kinda like THG's CPU charts. Just make the interactive system comparation machine. Choose a CPU, a mobo, a gfx card etc. If you bench every component (not every combo), but just CPUs vs CPUs, mobos vs mobos, you can get the relative score and construct a relative table for combinations..... hmm just a thought.

    A few mistakes made it into the final article...

    -------------------------------------------------
    Page 7

    1. The following bit does not belong in this review. Cut and paste?

    "There are absolutely no PCIe slots at all on the Neo4/SLI except for the pair of x16 slots for SLI video. MSI tells us that the 2nd PCIe can function as a PCIe x1 slot if you're not using it for video, but that is it for PCIe. Does this really matter? Right now, it really isn't important, since we had a very hard time even finding a PCIe x1 LAN card for the new PCI Express. It may matter in the future, but by that time, you will likely have moved on to a newer version of whatever chipset is the latest wonder. This is particularly clear when you look at the feature set of the MSI, since it is definitely a cut above the other boards in this roundup."

    2. "SPDIG" should be SPDIF, or S/PDIF if you want to be really accurate.

    Page 11

    1. The title row of the table is incorrect. The motherboard name should read:
    "DFI LANParty UT nF4 Ultra"

    2. Link to next page is also incorrect, same as above.

    Page 12

    1. Title of the page is incorrect, same as above.

    2. Title row of the table is incorrect, same as above.

    Page 13

    1. "SPDIG" round two.
    --------------------------------------------------

    Also, do guys have any idea why placing the codec on a daughter card reduces CPU overhead? Obviously there is something more going on than just the physical relocation of the chips. Any theories or explanations?

    Just a word about the soundblaster Live on the MSI board...

    "That price tag [200$] may be a bit high for the average gamer who just spent most of his/her savings on a Pentium II / Voodoo2 setup, however if you're going to swallow the cost of an expensive sound card it might as well be the Creative Labs SB Live!"

    That was Anandtech back in '99. And you're getting this for free! (well, almost)
