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 take it no one here has used soundstorm with doom3: crackling and cutting out, having to reset the sound all the time. pain in the butt, how is it great??jm0ris0n - Tuesday, October 19, 2004 - link
I still think that Anyone who would want SLI-PCIe WOULD NOT use onboard sound.Viper96720 - Tuesday, October 19, 2004 - link
Ah i see I thought that was agp it is the 16x pci-e.LotoBak - Tuesday, October 19, 2004 - link
55 -I take it your refering to this pic

That long slot is NOT agp. It is PCIe 16x. The two above it are PCIe 4x I believe (could be wrong on the 4x)

nVidia's decision to dump SoundStorm makes no sense. If it was a business decision because the OEMs and media (??) as an earlier posted pointed out.. how can they justify the extra expense of SLI? What OEM is going to use that high-end tech? (Hint: Not Alienware.. they've got their own stuff)The same people who want SLI want SoundStorm.. these enthusiasts are nVidia's core business (not by sales volume, by prestige, reputation, etc. in the marketplace) and not listening to your customers is a bad idea in my book..

I could care less about the soundstorm :-p*Drool@SLI goodness :-D*

#45 the board has AGP in case you didn't notice the long brown slot next to the PCI. The 2 small ones right above the audio is the PCI-E.RebolMan - Tuesday, October 19, 2004 - link
The reason soundstorm is nice is because it outpreforms "real" cards - thus leading to better enjoyment of said games by soaking up less CPU time!http://www.tweaktown.com/document.php?dType=review...
It produces a _better_ gaming experience in terms of sound, and still gets better frame-rates than a PC equipped with a SB Audigy Platinum Pro!

Why don't vendors pay as much attention to "APU" performance as they do to GPU performance?

BAH! Where's my SoundStorm!!!?!?!?Aquila76 - Tuesday, October 19, 2004 - link
#44 - That dual SLI board (page 3) looks like an MSI (VIA chipset? has an Envy controller at top) board, not the nForce4 SLI reference board. The nVidia reference board design may be different.
