| Performance Test Configuration | |
| Processor(s): | AMD Athlon 64 4000+ (2.4GHz) Socket 939 |
| RAM: | 2 x 512MB OCZ PC3200 Platinum Rev. 2 |
| Power Supply: | OCZ 520 watt PowerStream |
| Hard Drive(s): | Seagate 120GB 7200 RPM SATA (8MB Buffer) |
| Video AGP & IDE Bus Master Drivers: | nVidia nForce 6.39 |
| Video Cards: | nVidia 6800 Ultra (PCIe) 2 x nVidia 6800 Ultra (PCIe) SLI |
| Video Drivers: | nVidia nForce 71.80 |
| Operating System(s): | Windows XP Professional SP1 Direct X 9.0c |
| Motherboards: | Asus A8N-SLI Deluxe DFI LANParty nF4 SLI-DR Gigabyte K8NXP-SLI MSI K8N Neo4/SLI Platinum |
Tests used OCZ PC3200 Platinum Rev. 2, which uses Samsung TCCD chips. These same chips are available in memory modules from G. Skill, Corsair, Geil, Mushkin, PQI and others. Please refer to Athlon 64 Memory: Rewriting the Rules for more information on Athlon 64 memory performance.
At the present time, SLI is only supported by nVidia chipsets and video cards. All single and dual GPU benchmarks were run with a matched pair of nVidia 6800 Ultra reference cards, identified as Rev. A04. Other companies have demonstrated "SLI-like" dual video solutions or they have announced their intention to manufacture SLI-like solutions in the future.
All game benchmarks, both single video and SLI, were run in 1600x1200 video mode with 4X Anti-Aliasing and 8X Anisotropic filtering enabled. The exceptions are Aquamark 3, 3DMark 03, and 3DMark 05, which use a standardized 1024x768 setup to generate comparable benchmark results. These three benchmarks used standard mode, which generates a standardized score for comparison.

quote:I still do not understand why this argument is so popular. Why is the general assumption that purchasers of SLI capable boards will immediately want to jump into a dual-card config? The idea is flexibility. Sure, 2 6800's are expensive now, but they will inevitably get cheaper.Well, if history serves as a measure... by the time that 2nd board becomes cheap enough to justify its cost, there will be a new board out (say, the nVidia 7800) that will be as fast, or faster than, the SLI combo.
I used to buy motherboards with two sockets for this very reason (flexibility to upgrade to two CPUs later) until about twice doing this I learned that by the time I was ready for that 2nd CPU, there was one out that was faster than both put together.
Computers change too fast. If you perpetually buy on the bleeding edge, you cannot plan any upgrades past ~6 months and definitely not past 12 months. By that time, you'll throw away what you have and get the NextBestThing(tm). Buying SLI is bleeding edge. Saying that you'll buy the upgrade card in a year is just a rationalization to buy the bleeding edge now.

Yeah, that's right. Some apps run slower with SLI because nVidia hasn't SLI optimized the driver for that app (so it can then only utilize one card) and the SLI setup uses some overhead, resulting in slower results. Any new game/benchmark will use SLI just fine. The results in Half-Life and Doom 3 as well as if you add the config for stuff like NFS:U2 and whatever are well above one card though.Sunbird - Tuesday, March 1, 2005 - link
Is my brain screwed up or are the 3Dmark03 single scores higher than the SLI scores???chup - Tuesday, March 1, 2005 - link
too bad, i thought the MSI was the one to get after nforce2.sphinx - Tuesday, March 1, 2005 - link
From this review, I have come to the conclusion that ASUS is slipping. I have always been a supporter of ASUS but, I think this review shows how much ASUS is all about the money and not making quality products. Right now I am waiting for manufacturers to get the VIA chipset working properly. I haven't seen many news or reviews on VIA's new chipset. One other thing. Who in their right mind would spend close to $250 on nVidia's NF4 if there is really no significant performance jump from the NF3.bigbusa - Tuesday, March 1, 2005 - link
You mentioned the asus manual says use a 500+W PS. if you read the Asus users guid the sli 6800 ultra system also has all pci slots used, all memory dims full, 2 optical drives, and anassortment of other stuff. and they recommend a 500+W, but a 350W PS for a dual 6600GT. See below.500+W ps for 55FX, 2x6800 ultra, 4ddr dims, 4 HD's, 2 optical, 1 pcie 1x card, 3 pci card, 1 1394, 6 usp devices. (shit thats alot of gear)
350W for a 3400(64bit 939), dual 6600GT, 2 DDRdims, 2 hd's, 1 optical drive, no pcie 1x, 1 pci card, no 1394, and 3 usb devices.
SO the article is misleading a bit.
The review also did not cover any quad displays and problems one may encounter when setting this up.

#70 - None of these boards support ECC. The reason for that is that such support would be implemented by the memory controller, not the motherboard manufacturer. In this particuliar case the memory controller is integrated into the CPU. AMD has a line of CPU's that have ECC support, they are called the Opteron and are designed for workstations and servers.In the home user market ECC does not significantly impact stability but it does harm performance by a small amount which is why the feature is not generally available on consumer solutions.

All in all I think that this is the best review of Socket 939 SLI boards that I have seen. I particularly liked the attention paid to storage and I/O capabilities. My one criticism is that although comments were made regarding stability, and a link was made between overclocking and stability, there was no discussion of ECC support. If system reliability is discussed, ECC should not be ignored. As far as I can tell, the only board supporting ECC is the ASUS board. Over the years I have found it difficult to get accurate information on ECC support, having been given misleading information on occasion by both MSI and ASUS.Aquila76 - Tuesday, March 1, 2005 - link
D'oh, *SoundSTORM Savior*That's it, I'm off to bed. It's quarter of 1:00AM and I have work tomorrow. Uh, today.

To everyone hoping the MSI upsamples analog 5.1 to Dolby Digital - I don't think so. Like any Creative card, it can either downmix DD-EX/DTS-ES 7.1 streams to 4/5.1 speakers (which is what page 5-11 of the manual is actually talking about doing), decode DD/DTS on-card to 5/6/7.1 speakers (via analog or 'Digital Out', Creative's proprietary digital link for their speaker sets), or can just pass the Dolby Digital/DTS 5/6/7.1 signal (now via the SPDIF coax/optical cable) to any outboard decoder.I say this because I have the same exact chip on a stand-alone card, and it does not upsample analog sound to Dolby Digital, like SoundStorm did. 'Digital Out' simply let's you use a proprietary Creative Digital DIN connector to connect one cable from the soundcard to the Creative speaker amp (like on a DTT3500 that I use).
I also find it highly unlikely that Creative would license a DD Live capable chip to only one manufacturer when they have yet to produce one of their own cards with this feature.
