Test Setup
| Performance Test Configuration | |
| Processor(s): | AMD Athlon 64 4000+ (2.4GHz) Socket 939 |
| RAM: | 2 x 512MB OCZ PC3200 Platinum Rev. 2 |
| Hard Drive(s): | Seagate 120GB 7200 RPM IDE (8MB Buffer) |
| Video AGP & IDE Bus Master Drivers: | nVidia nForce 6.31 (nForce4 SLI) SiS 1.17e VIA 4in1 Hyperion 4.51 (12-02-2003) nVidia nForce Platform Driver 4.24 (nForce3 Ultra) |
| Video Card(s): | nVidia 6800 Ultra (AGP 8X) nVidia 6800 Ultra (PCI Express) |
| Video Drivers: | nVidia nForce 61.77 (SiS, VIA, nF3U, Intel 925X) nVidia nForce 71.40 Beta (nForce4) |
| Operating System(s): | Windows XP Professional SP1 |
| Motherboards: | DFI LANParty nF4 SLI-DR DFI LANParty UT nF4 Ultra-D Winfast 755FXK8AA (SiS 755FX) Soltek K8TPro-939 (VIA K8T800 PRO) Epox 9NDA3+ (nForce3 Ultra) nVidia nForce4 Ultra Reference Board Abit AV8 PRO (VIA K8T800 PRO) ECS KV2 Extreme (VIA K8T800 PRO) Gigabyte K8NSNXP-939 (nVidia nForce3 Ultra) MSI K8N Neo2 (nVidia nForce3 Ultra) MSI K8T Neo2 (VIA K8T800 PRO) |
Tests used OCZ PC3200 Platinum Rev. 2, which uses Samsung TCCD chips. All memory ran at 2-2-2-7 timing in benchmarks on the DFI nForce4 boards.
The nVidia 6800 Ultra AGP was used for testing in all 939 chipsets other than nForce4. The PCI Express 6800 Ultra was used for all testing with the nForce4 and the Reference Intel 925X. Resolution in all benchmarks is 1024x768x32 unless noted otherwise.
Results for the DFI nForce4 boards are color-coded red in all graphs. VIA K8T800 Pro based motherboards are in green in our results, and nVidia nForce4/nForce3 are in orange. Results for the SiS 755FX based Winfast are yellow in all graphs. Intel results are included for Reference only and are blue in the graphs. The color coding should allow easy comparison of the tested DFI nF4 to other nF4/nF3 results and to other chipsets and processors.

If you don't like the exclusive, wait for the NF4 roundup. It's that simple. Just because you feel enough data wasn't included in an ARTICLE, doesn't mean that Anandtech does not have such data in their LABS waiting to be released. Again, wait for the roundup.overclockingoodness - Saturday, February 5, 2005 - link
Justimann: Like others pointed out, Wesley is one of the most respected journalists in this industry. And AnandTech is one of the best sites as well, so I doubt they will be putting their integrity on line just to get a damn exclusive. AnandTech is just like any business but I am proud to say that I have hardly seen any bias on this site (the only bias may be disagreement between my interpretion of the reviwer's words).AnandTech would never recommend anything unless they are confident about it and even if the data is not on the graph, we trust AnandTech's editors.

I dont remeber if people have asked this yet(having a feeling they have, but I dont want to read 5 pages of replys;)) but do you guys at Anandtech still have some Winchestor CPUs lieing around? Would be nice to see how far you could get one :)bersl2 - Saturday, February 5, 2005 - link
#79, #80: It's got nothing to do with any of that. SLI nForce4 chips have a price premium on them. Every Ultra sold instead of an SLI means less money for nVidia.joe4324 - Saturday, February 5, 2005 - link
Its more likely that nvidia doesnt want to deal with supporting hardware running out of spec AND beyond its intentions, There not stupid, they know how people are. Even if this board preformed perfectly in all ways, UNTILL you modded it. then it caught fire. They would be slamed for being unreliable and unsafe, and thus not worth buying. even though it was the best mobo out at the time, when NOT modded.rjm55 - Saturday, February 5, 2005 - link
I don't get it. Why did nVidia do this? If anybody did a mod to SLI they had to buy two nVidia video cards to use SLI. So nVidia got more profit. Looks like they couldn't lose with SLI only working with nV cards.Guess nVidia has now totally forgotten their gaming and enthusiast roots and they're just another big company throwing around their weight. Maybe ATI will do better.

The following Update has just been added to the front page of the review:"UPDATE 2/05/2005: nVidia has acted to prevent, or at least make it more difficult, to mod the Ultra board to SLI. First, DFI has advised us, and posted on their website, that they will NOT sell the SLI bridge to buyers of the Ultra board. Second, nVidia has advised us that future shipments of the Ultra chipset have been modified so that the mod to SLI will no longer be possible. An additional side effect of this second action is that the "Dual Video" mode, which performs at about 90% of SLI performance levels, will only work with early nVidia drivers 66.75 or earlier. If you do a quick check of web driver postings you will see it is now very difficult to find 66.75 drivers. With a chipset modded to SLI the "Dual Video" mode worked through 70.xx versions of the nVidia driver. nVidia also made it clear they will continue to make driver changes to prevent operation of any "non-standard" (8X/8X) operation of their SLI driver. This also throws into question whether the VIA "dual graphics" mode on the 894 Pro chipset will ever work with nVidia graphics cards. If you are interested in the current UT Ultra-D we suggest you buy one now if you can find it. Future versions of the UT Ultra-D will not have the same capabilities as a result of these actions."

I guess beauty is hard to quantify. Like Wesley said he has saved the Editor's Choice Award for the SLI board review that will provide more hard data to support his opinion on the DFI board.justinmann - Friday, February 4, 2005 - link
Dear Gerbil, I am not wasting my time. I read the article, and like any good scientist I looked at the data. The data do not support the conclusions, therefore I felt it necessary to ask why he did not perform an experiment that backed up his proclamation. It's really a pretty simple concept.Justin

Hey Wesley,You did use a IDE HDD for benchmarking so the question about SATA and overclocking pop right to my mind: Is Overclocking as stable with SATA drives?!?
I know that the NF3 250GB was, but sometime engineer can make silly mistake. ;)
An can you or DFI confirm that the low end (Utra-D) will have as much success with OC? Thanks...
