The NGO Patcher adds several INFs to your Windows configuration -- the result should enable SLI in your NVIDIA toolbar
Dying to give SLI a try but don't have quite the right motherboard? A new patch might give you a sneak peak

A few days ago we reported on the leaked ULi driver patch that enables SLI on any Detonator driver if the patch finds a ULi Northbridge.  ULi (ironically now NVIDIA) created the patch to work with existing and future NVIDIA drivers -- other similar hacks required the use of ancient drivers to work correctly. 

A few people were able to take our advice and create a patcher from the ULi INF files.  The result?  SLI on any platform, no matter what the chipset (just so long as you have two PEG adaptors). 

Several motherboards have multiple PEG slots, but without the SLI license from NVIDIA, those motherboards have never been sanctioned to run SLI mode.  Motherboards that currently have multiple PEG adaptors but are not authorized to run in SLI mode include:
  • Intel 975X
  • Intel Q965
  • Intel P965
  • Intel 945P
  • VIA K8T900
  • ATI RD580
  • ATI RD480
  • ULi M1697
  • NVIDIA nForce4 Ultra
  • NVIDIA nForce4 4X
Feel free to give these chipsets a try and report your success.

This 'exploit' has been out there for a long time. I think nvidia purposely leaked it. Since it was 'leaked' they don't have any responsibility to insure that it works correctly, or devote any support resources to it. If it does work, it sells more of thier cards.

bingo! we have a winner!

I don't think thats really the case, those looking for SLI will buy the cards anyways. What this does is sell less nvidia nforce4 SLI chipsets.

Well, seeing as how nVidia now owns ULi, they put it out themselves...therefore, I doubt that they're going to bring lawsuits against themselves.

It's the reverse engineering that had to happen that's a violation of the DMCA. The patch was leaked out, not released.

Yeah. NGO could be in a sh!tstorm of trouble for that little coding feat. Is that even DMCA law-breaking? I would think even the general copyright laws from days of old would cover something this.

Pretty soon there'll be an NVIDIA press release: It's on like Donkey Kong, beyotch!

So when they say multiple PEG adapters, does this mean like 1 16x and 1 4x. Because I have an nForce 4 Ultra and it would be sick to run two 7800GTX's. I think ATI should do something similar to this for Nvidia mobos.

PEG = PCI-Express Graphics

It has to be a full-length slot (e.g. x16 physical connection)

aw poo....Oh well...I always thought SLI and crossfire were too expensive for me anyways.

Die Proprietary solutions

I think this kind of solutions, where you are forced to use parts of the same manufactures, are against the principle of the PC computer.

Good were the days when even diferent brands of CPUs uses the same socket.

We should stand against this kind of thing, or soon we´ll have a lot of parts that are not compatible with other brand´s parts, and we´ll have a lot of Apple´s like computers.

Can you imagine ATI cards with their own slots, and Nvidia with another slot, PCI-E-A and PCI-E-N!!! Lol!

not impossible

also, does this work for dual gpu cards? cuz then you wouldnt need 2 pegs, but could still use the SLI dual gpu cards. or maybe you could always do this?

We already have this in the notebook stage... Axion versus MXM.

Wonder how log it will be before Nvidia puts a stop to this? I always thought that SLI/Crossfire should work on any motherboard with dual PEG slots.

How fast can you say "cease and desist, DMCA violation?"

About time

It is well known that Nvidia put in the artificial limit. The whole point of PCI-e and PEG certifications is to ensure that different card will work with different controllers. It is complete BS that Nvidia claims they put in the lock to ensure the platform will work properly. If it is PCI-e compliant, it should work.

Graphics manufacturers created multi-card designs to sell cards, not motherboard chipsets. They would be doing themselves and everyone else a favor to lower the cost of implementing this. I can definitely bet that Nvidia would much rather sell more GPUs than northbridges.

Why do one or the other? They're selling more cards AND more chipsets, they're creating brand lock-in.

But is it worth it?

This opens the door for one last benchmark which could really show off some core logic tweaking - let's fire up a pair of 7800s on an RD580 and stack it against a good ol' SLI-32 mobo, and again with an RD480 against a standard SLI.

I think everyone already knows that the I/O functions (particularly the USB) are better on the nVidia offerings, but this would be a good chance to test a lot of other features head-to-head.

sweet! now just make a patch to run another X1900XT on my A8N32!!!

Those are not motherboards, those are chip sets.

SLI on an A8R32-MVP. Sweet.

Bridge adapter?

Will still likely need the SLI bridge for full speed operation, unfortunatly.
