The nForce4 Family
The nVidia Reference Board was shipped with the nForce4 Ultra chipset. The features of the nForce4 chipset family should be very familiar to nForce3-250 users, since it builds upon the feature set of the nForce3-250 family that was introduced in April. All of the new nForce4 chipsets support 20-lane PCI Express, native Gigabit Ethernet (on-chip), full nVidia RAID features, 10 USB 2.0 ports, nVidia Firewall 2.0, and the new nTune Performance utility. From there, however, the 3 members in the new nForce4 family differ a bit in features depending on the target market for the chipset.
nForce4 - the basic value chipset for 939 and754. This is the chipset that you will likely find in Socket 754 and low-end Socket 939 boards selling for less than $100. The nF4 is targeted at value boards, but it still includes on-chip gigabit Ethernet capabilities, support for 10 USB, full nVidia "any drive" Raid capabilities, support for nVidia Firewall 2.0, and support for the nTune Performance Utility. Four SATA drives are supported at current 1.5GB/s speeds plus four PATA (IDE) devices. The big disadvantage of the vanilla nF4 chipset is that it only supports 800 Hyper Transport. In addition, the HT bus is locked on the basic nF4 to prevent overclocking of the Hyper Transport. This means that the basic nForce4 is not a good choice for the enthusiast, who is better served by the Ultra and SLI chipsets.
nForce4 Ultra - the mainstream nF4 designed for boards that will sell in the $100 to $150 price range. In addition to nF4 features, you will find full support for an unlocked 1000 Hyper Transport, support for 3Gb/s SATA drives, and nVidia's secure networking engine, which is called ActiveArmor.
nForce4 SLI - the high-end version of the nF4 is designed for boards that will sell at $150 or more. The nF4 SLI is the only version to support programmable PCI Express lanes, which allows the use of either a single or dual Video Card. A single GPU is supported by an x16 PCIe slot, which can be reprogrammed to two x8 PCIe slots to support two video cards in SLI mode. All features are, otherwise, the same as nForce4 Ultra.

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.

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?
