The DFI boards all support the full range of nVidia nForce4 features including nVRAID, Active Armor, SATAII 3Gb/s drives, NCQ, any-drive IDE/SATA Raid, PCIe Gigabit LAN by a PHY Ethernet chip (plus an additional PCI Gigabit LAN), and the nTune utility.
Packaging for the full LANParty nF4 SLI-DR is typical LANParty.
DFI has continued with the Karajan Audio Module first introduced on their LANParty 925x. As you will see later in our audio tests, the Karajan module was a much better performer than what we expected when we first saw the onboard Realtek 850 codec. We still wish that DFI had been able to use the High Definition ALC880 or a similar chip instead of the more common ALC850. However, the Karajan Module on the DFI SLI does provide the lowest CPU overhead that we have seen on any board using the 850.
The ALC850 Codec provides four pairs of stereo outputs, with 5-Bit volume controls and multiple stereo and mono inputs, along with flexible mixing, and gain and mute functions. Two 50mW/20ohm headset audio amplifiers are integrated at Front-Out and Surround-Out, and both amplifiers are selectable for Front-Out, Line-In and Mic-In as a Universal Audio Jack.
You can find more information on the ALC850 at Realtek.
DFI provides a full selection of rear I/O ports. These include 6 programmable audio mini jacks plus coaxial SPDIF in and out connectors to support the Realtek ALC850. The back panel also includes PS2 mouse and keyboard, 1 standard Firewire (IEEE1394a), 6 USB, and two RJ45 Gigabit Ethernet. There are no rear ports for a Parallel Printer or serial devices, but there is an onboard header for an external serial device an IR header.
The four DIMM slots support up to 4GB of up to DDR400 memory in a Dual-Channel memory configuration. Dual-Channel 1 is DIMMs 1 and 3, and Dual-Channel 2 is DIMMs 2 and 4. DFI specifies support for both ECC and non-ECC unbuffered memory. Contacts at DFI advise that best overclocking is achieved with the dual-channel DIMMs in Sockets 2 and 4.
Board Layout
The DFI LANParty nF4 SLI-DR is very well arranged, with almost everything located where it works best. As you will see if you study the layouts of the other SLI boards, the DFI differs substantially in layout.The DFI nF4 place the CPU in the top center of the board and DIMMs at the top. This arrangement worked well in our testing and should work better (for those who change memory frequently) than in the crowded right-hand alternate location used on many boards.
There is plenty of room around the Socket 939, so most Heat sink/Fans should work fine. A Zalman 7000 overhung DIMM slot 4, but it still cleared our stock OCZ memory and memory could work in all slots.
The IDE connectors are at our preferred upper right edge of the motherboard, and the floppy connector is a board edge connector located on the right edge around the middle of the board. Both locations worked well in our testing.

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.
*Keeps waiting for a SoundStrom Saviour*
