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.

    #33 - Wesley, that's awesome news. Can you post that somewhere more important so buyers know to be on the lookout for it? =)

    Good article!

    I'm seriously considering dumping my DFI S754/NC 3200+ setup for that Epox board and a cheap S939 A64 :)

    #29 and #31 - UPDATE: I have talked with contacts in the Memory Industry and Samsung TCCD is now available again from Samsung. TCCD disappeared for a few months but production didn't really stop. TCC5 is DDR466 and TCCD is DDR500, but both chips come off the same line and are binned for speed grade. Samsung stopped binning for DDR500 grade until recently - and left this job to the memory makers.

    Recently Samsung has told memory makers they are binning once again for DDR500/TCCD and the TCCD chips are available again. It will take a few weeks for the pipelines to fill but TCCD is not dead. Some companies are staying with TCC5 at a lower cost and binning for the top performance unless the yields start to go down.

    #24 - The base nForce4 is sometimes called the nForce4 X4 and runs at 800 HTT, while the Ultra and SLI run at 1000HT. When 1000HT was first introduced we found no real difference in performance at 800HT and 1000HT. What the 1000HT did provide was quite a bit more overclocking headroom. A reader may have an example of where 1000HT outperforms 800HT but the real world difference is negligible.

    #28 - There are now more than 60 BIOS releases for the DFI nF4, many customized for particular memory types. Only 3 have been posted to their website. For the latest DFI nF4 BIOS a good place to check is www.xtremesystems.org or the BIOS Files Forum at www.bleedinedge.com. There is now a 7/04 BIOS that is reported to be more stable in upper memory ratios (433,466,500) with Rev. E chips.

    #29 - You are overstating the TCCD situation. Corsair still sells TCCD, as do several other memory vendors. There is no doubt TCCD is drying up everywhere but Corsair, and that will continue. New TCC5 dimms that are said to perform like TCCD are in process in at least one memory company. We have requested these new TCC5-based dimms and will share our findings as soon as we receive the memory. There are also some new BH5 dimms that we thought were gone forever. We have even seen the new BH5 binned and advertised as DDR500 2-2-2 at higher voltages around 3.3V.

    Well, while this review -has- convinced me to go with the DFI board over the Chaintech, that is purely due to the audio CPU usage issues of the onboard vs daughterboard. I'm shocked at how much difference that makes.

    That said, most of the memory testing (and thus most of the review) was meaningless to me (and everyone else who doesn't have access to TCCD memory anymore). =/

    #17 - Thanks for pointing out the errors. They have been corrected. Do you want a job proof reading :-)

  • yacoub - Wednesday, July 6, 2005 - link

    Regarding the tRAS recommendation:

    Can we petition Anandtech to stop using memory that the consumer can't get anymore? (Namely TCCD-based Plat Rev2.) Go pick up some TCC5 and do your tests with what the consumer is actually going to be receiving so your tests actually mean something.

    What BIOS version did you use with the DFI? It reads: "Award 7/01/2005 Release" in your list of features for the DFI, but I could not find that BIOS release on their website.

    Sorry I meant: GA-K8NF9

    I'd liked to see the Gigabyte GA-K8NP9 reviewed, because it has passive southbridge cooling (silence :) ) and is cheap.
