Reference Boards are normally quite different from the production boards that will later appear with the Reference Board chipset. While certain component arrangements may be retained from a Reference Board, the board is designed for testing and qualification, and generally not for production. They are also normally designed to be tested on the bench, out of any case.

The introduction of the nForce3-250 chipset family moved nVidia to a leading position for Athlon 64 chipsets. nForce4 builds upon the nForce3-250 update with the addition of PCI Express. The rearrangement includes an x16 PCI Express graphics slot, 2 x1 PCIe, two SATA controllers capable of 3Gb/s speeds, and 10 USB ports.
nVidia has not had SoundStorm on any nForce3 chipset, so for the past year+ SoundStorm has been "missing" on any nVidia chipset for Athlon 64. We raised this issue for nForce3-150, then for nForce3-250 in nForce3-250 - Part 2. This has not changed with nF4. The nForce4 Reference board uses the AC'97 2.3 compliant 8-channel Realtek ALC850 codec. More information on the ALC850 can be found at Realtek ALC850 Product information.

Fully decked out, nForce4 provides features currently available nowhere else, like on-chip 1GB Ethernet, on-chip firewall, 4-drive SATA RAID, and both SATA and IDE RAID that can be combined. The nForce4 SLI adds the option to combine two nVidia video cards in two x8 PCIe slots for a huge increase in video performance.

I'm going to back people up on the annoyance of not having soundstorm or atleast something about the audio system. Any nforce2 owner knows how good sounstorm is, i've got an audigy2, and any non EAX source goes through soundstorm for me.I can't believe for enthusiast motherboards, they are touting features like firewalls, 90% of us use routers, its just not that exciting anymore.
Disapointed.

I think I read somewhere (probably The Inquirer) that nVidia isn't including Soundstorm cos they don't want to pay for a Dolby Digital licence or something.If people don't like the onboard solution, they can just slap an old Sound Blaster Live in the system for peanuts. I do that and it keeps me happy.

there is this online petitionhttp://www.petitiononline.com/NVAPU/petition.html

dude, where is my soundstorm?This is a rip off to the general consumer, and would have hoped that Anandtech would have picked up on it and made a mention of the problem --
What doesn't nvidia get? there is a huge demand for soundstorm.
Nforce4 is a step back from all the other chipsets in terms of audio.
Intel is pushing hi-def audio, via has got its ENVY series, why would nvidia leave out soundstorm
boooo nforce4
booo Anandtech for not pickup on this

One more thing,Would all the monitor hookups on the cards be active. That would be great cause you could put to gether quite a nice 4 monitor workstation for pretty cheap. you could get those 2 6600GT's and 4 Viewsonic VP171's for about ~$2200. No more expensive then a high end 20"-23" display, and a lot better picture and performance and space (564 square inches vs only 373 for an apple 23" HD Cinema).
Just wondering.

holy crap i want one so bad.BTW, if any one wants a nice big tax write off, my college TV station is looking to replace our PII and PIII video editing and station machines. So if anyone has some extra hardware laying about.....
(No joke, we really, really need new gear).

wait a min,I've seen benchmarks on the web for NVIDIA SLI cards. I don't remember which exact cards were used, but I do remember that one ran in a 16x slot and the other ran in an 4x slot with a 16x connector.
The point, the 4x slot has more than enough bandwidth because it worked perfectly. With no perfomance loss.
Wish I had the link somewhere.
So any chipset that supports pci-e should handle sli just fine, as long as the mobo maker puts two physical 16x slot connectors, regardless of their actual bandwidth.

Will mobo manufacturers increase the possible Bus speeds? Please say yes, I would love one but I want to get to 290... Page 7 says max is 250, that is not ok..plewis00 - Tuesday, October 19, 2004 - link
Can you run, say a 6600GT and 6800 Ultra in SLI? Seeing as they are both Nvidia and the SLI connector should be in the same place?
