Can Crossfire run on any nforce chipsets?

[panfist]

I have an Asus p5n32-e SLI Plus. I was wondering if there was any possible way to get Crossfire enabled with my x1900xt 512mb. I tried searching, which mostly turned up the answer "no," but nothing definitive after an interview from Sept. '07 in which HP was going to put Crossfire on 680i SLI. Did anything ever come of that?

If it matters, my motherboard actually has two SLI chipsets: C55+MCP55P; a.k.a. nForce 650i SLI & nForce 570 SLI.

No,CF is not possible in a Nvidia chipset because Nvidia doesn't want to
There is a Striker Extreme(680i) with a BIOS that allows CF but only HP I believe has that BIOS and they only give it to you if you buy a all new system

isn't it ATI who would have to enable it in their drivers?

Gl@re, it takes both to work. Legally ATI can't allow someone to run CF on someone else's board unless they agree to it and then both work on new BIOS and drivers that would enable it.

It is not a problem with the hardware or software but a legal one.

crossfire dosnt need ati/amd approval they dont own it, its owned by the crossfire consortium and NV puts blocks in their bioses to stop pci-e to pci-e transactions that arnt digitally signed with an sli marker

crossfire is free to implement in cards and chipsets and on the MB front it just needs to have 2 or more pci-e 4x or greater slots

If you have the proper BIOS and drivers might be possible ... :shrug: But why would anyone do that (Holy :banana::banana::banana::banana: :ROTF:) ? For tighter ram timings ... ? X38 / X48 can provide you with high ram operation frequencies, that is what counts the most today ... ;)

Thanks for all the response.

I realized crossfire really wouldn't be the best route anyway. I have an x1900XT that I wanted to juice up but really I can just sell it for ~$100 and buy a 9600GT or 8800GT that will get me better performance and ASTRONOMICALLY better performance per watt.

That's definately your best bet.

The x1900xt was a great card, but it's past it's prime.

The HP Blackbird 002 (designed by Voodoo Systems, see the HP/Voodoo buyout) runs Crossfire on an nVidia 680i chipset, but you, the end user, will probably never have that ability.
