nForce4 SLI Roundup: Painful and Rewarding

The Roundup
The four motherboards in this roundup represent all of the motherboards currently on the market that support SLI. This includes the three motherboards from the largest tier one manufacturers: Asus, Gigabyte, and MSI. The surprise in this group is the very early DFI nForce4 SLI and Ultra boards from a tier 2 manufacturer. Why is this a surprise? Tier 1 manufacturers generally get favored treatment from chipset manufacturers because of the sheer volume of board sales that they represent. This means that they get chips first, reference designs first, and lots of manufacturer design help. Particularly in this launch, nVidia made it clear that none of the tier 2 manufacturers would get SLI chips or design assistance until after the Tier 1 launch of SLI motherboards.DFI basically went their own way in the design of their SLI and Ultra motherboards so that they could get to market when tier 1 SLI boards would arrive. This is why the DFI is unique in design and unique in the ability to mod an Ultra to SLI as we discussed in Morphing nForce4 Ultra into nForce4 SLI. You can also find a launch review of the DFI Ultra and SLI chipsets at DFI nForce4: SLI and Ultra for Mad Overclockers.
Other motherboards in this roundup received extensive pre-production coverage. Anand covered the MSI K8N Neo4 SLI in prototype in Taiwan. The Asus pre-production board was used as the Reference board for the nVidia SLI launch, and the Gigabyte SLI received a First Look in late November.
Since those early reviews and announcements, we have been looking for a Forum to compare actual production models of all these motherboards using consistent test procedures and benchmarks. The buzz surrounding these SLI boards, the huge sales that they are generating, and the fact that single video performs the same in nForce4 SLI and nForce4 Ultra made the SLI roundup the perfect vehicle for launching our new motherboard test suite.
All testing for the SLI roundup was performed from scratch for each of the SLI boards. We felt production models deserved a fresh new look to help you decide better which SLI board, if any, to choose for your next system.

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.
