Socket 940 Roundup: Motherboards for the Athlon64 FX

Media Encoding and Gaming Performance
The most recent BIOS upgrades from Asus have really improved gaming performance. The SK8V is now dominant across all gaming benchmarks except GunMetal 2, which produces unusual results on the Socket 940 platforms. If we discard the suspect GunMetal 2 results, the Performance advantage of the SK8V is very clear. With the on-chip Memory Controller of the A64 series, this kind of variation in motherboards was not expected at all. Asus has done an outstanding job with the SK8V as you can see in the gaming benchmarks.
nVidia assured us that the recent 11/03 update to their nForce platform drivers would bring better performance in nF3-150 PRO benchmarks. For that reason, we retested the Gigabyte nF3-150 PRO and re-ran benchmarks with the SK8N to provide the fairest comparison. The 11/03 nVidia drivers made almost no difference in gaming benchmarks, but we did see some improvements in other areas. Our standard Video card for benchmarking is the ATI Radeon 9800 PRO 128Mb. Perhaps we would have seen an improvement in game scores had we tested with a top nVidia card. However, in our standard A64 FX test setup, the nForce3-150 PRO lags behind the K8T800 in gaming and encoding performance.

Since this review is for the Athlon64 FX motherboards, shouldn't the links for the "Anandtech Deals" (just below the title) be for Athlon64 FX (socket 940) instead of the non-FX 3200+ (socket 754)?O_o

#7 -The scores with the 11/03 nVidia platform drivers combined with Catalyst 3.9 and the latest BIOS' we tested have dropped the GunMetal 2 benchmarks to those reported in this review. We have discussed the very unusual GunMetal scores we got in the past with Yeti Studios who is looking into the scores.
At this point, we are concerned that the GunMetal 2 bechmarks are really telling us very little about the performance of the boards and systems we are testing. Unless Yeti can update or explain what we have been seeing in Socket 940 scores, we will likely drop GunMetal 2 from our benchmarks.
We apologize for the confusion regarding GunMetal 2 bechmarks, but we have shared with you over several reviews our growing skepticism over their validity in benchmarking FX and Opteron.

#7, if you look at those benchmarks in question, the results are HIGHLY questionable in the original benchmarks. They even mentioned it at the bottom of the page:"The astounding scores in GunMetal 2 by the Dual-Channel Opteron and Athlon64 FX51 are difficult to explain, since they are not duplicated by our single-channel Athlon64 benchmark. We were convinced that these scores on the original Opteron must be a fluke until they showed up again in our tests and retest of the K8NNXP-940 Dual-Channel."
My bet is that the earlier versions of the GunMetal benchmark were in some way flawed. Perhaps it was a driver issue, and the game was really only rendering about 2/3 of the screens that it was reporting. Given that all the other systems appear to be close to maxed out on frame rate by the graphics card, the FX and Opteron scores were initially incorrect and have now been fixed.

Wesley Fink, I have had issues with previous Anandtech articles and I thought (or at least was hopefull) that they would happen less often with some of the new staff. I now regret being so hopefull as I am still seeing the same problem.What I would like to know is what would cause the gun metal benchmarks on the Gigabyte K8NNXP-940 to drop 25% or more since the review of that same board on 9 Oct (there was even a link to this article on page one).
I realize that the motherboard and video drivers have changed along with some hardware, and BOIS updates mentioned on page 1 (stating that they "offering improved performance and added features"). The thing is that none of these changes should lead to this kind of preformance hit. What is the story here, was there a mistake in benchmarking, if so what article is correct, if not how do you explain this since most of the other benchmarks on this board varied (an estimated)5% or less.

Doubtful #5 as there is no BIOS option to enable or disable it for the VIA boards.bex0rs - Friday, December 19, 2003 - link
The integrated LAN on the SK8N is 10/100 only, not gigabit as mentioned several times.http://www.asus.com/prog/spec.asp?m=SK8N&langs...

Also, would there be any way to run the HT bus on the VIA boards at 600 to make a determination if that is the limiting factor on nV's implementation?

#1 - You are correct, and page 4 has been corrected. The SATA ports for the SK8N were correctly stated as 2 in the Feature listing for the 4 motherboards.Icewind - Thursday, December 18, 2003 - link
Unless im mistaken #1, is that one right next to the CPU cooler itself in the picture below? Hard to judge from the contrastIcewind - Thursday, December 18, 2003 - link
Best to wait for the 939 pin socket without the unregistered memory modules. I know I will. Paired with a possible PCI Express, SATA 2.0, ATi's 420, 2004 is gonna be a freaking expensive upgrade but better get the best before I finally move outa my folks house.adipose - Thursday, December 18, 2003 - link
http://anandtech.com/mb/showdoc.html?i=1936&p=...On this page you state:
The IDE connectors, IDE RAID, and 4 SATA connectors are all in good locations. They should present no problems in most case designs.
But I believe the SK8N only has 2 SATA connectors, and I can only see two on the image.
