AMD/ATI support confirms that Crossfire should work on Nforce4 SLI chipsets

This is great news for those of us with SLI boards. I don't know if I'm willing to shell out for an X1900 Mastercard at this point in time but at least it opens up possibillities for the future.

CSR: In order to run crossfire on your system. You will need a crossfire edition card. The cross fire edition card will be your master card and the crossfire ready will be in your slave slot on the motherboard. For the radeon x1950 crossfire edition card, you will be able to install a crossfire ready 1900 card as the setup. However, runing in this setup will downgrade the x1950 crossfire to a radeon x1900 series.

Me: Thank you for your reply. Could you confirm for me that I will be able to run Crossfire with an X1900 Mastercard, my current X1900XT, and my DFI SLI-DR Expert Nforce4 SLI motherboard?

CSR: You should be fine as long as you have a x1900 crossfire edition as your master card and another x1900 in the system. Your motherboard should also be crossfire ready or have 2 pcie slots.

Me: Will a motherboard with an Nforce 4 SLI chipset satisfy the above requirements?

CSR: Yes, as long as the motherboard has 2 pcie slots, you should be fine. You should also make sure that your powersupply is at least a 550w with 6 pin connectors for the video cards. Remember that these cards require a direct connection to the power supply.
 
Quite possibly. I tried to be as explicit as possible. It's a bit too late in the product curve for X1900 Crossfire to make much sense now anyway.
 
I added the question to the case. Any other details anyone wants me to add? Maybe if I bug them enough they will escalate my case 😛
 
So this means that SLi works on crossfire motherboards?

Wait what are the crossfire requirements? just a motherboard with 2 PCI-e x16 slots? (master/slave also)

Well, if the CSR is accurate it's Crossfire that would work on SLI boards. Nvidia's drivers definately do lockout SLI based on chipset.
