Windows 7: SLI/CrossfireX motherboards

Hey guys,



I noticed that the most SLI-ready motherboards are only intel CPU compatible.
Are there any AMD SLI motherboards out there or can I just set up SLI on a AMD CrossfireX-ready motherboard?

I really haven't seen any motherboards with both "AMD" and "SLI" in the same sentence.

most INTEL boards offer SLI and some AMD boards offer SLI

Honestly I havn't seen to many Intel boards offering Crossfire im sure they are out there just havn't seen to many ....

Contrary to myth you can mix ati amd hardware with nvidia intel hardware but mostly the video card and mobo nothing else .....

I would do a search on this actually if, I were you google some imformantion

Couple of other members here might have better information on it

in this case i would go with more of what you are shooting for either way both will do the job

After doing some research a couple weeks ago, and being an AMD guy myself, I've come to this conclusion. You can use SLI (nVidia) or Crossfire (Radeon) on any motherboard that has the compatible PCI-E slots. The main difference is boards that have built in Radeon GPU's are Crossfire ready, and just by adding a separate PCI-E video card, you can be utilizing Crossfire without having to have two video cards. However, if you have one of these Crossfire mainboards, you could disable the integrated GPU and use your two SLI nVidia Graphics Cards. I bought a Crossfire mainboard that doesn't have a built in GPU. So I can use either. Only thing is....I gotta buy two of each card to do so.

Hope this helps.

nForce AMx socket mobos are SLI. The 750a and 980a for example are AM3 socket and SLI compatible.

Actually I might be wrong about this but I'm not finding any information that's new on it. I'm going to try and run my setup with SLI and I'll let you know what happens.

nVidia requires a license to sell a motherboard that supports SLI. Some of the early boards based on the X58 chipset (Socket 1366) were sold without SLI licenses. I'm not sure that any vendor are now selling X58 boards without SLI. There are also Socket 1156 and 155 boards that support SLI. I believe they all support CrossfireX as well. (AMD/ATI requires no license.)

nVidia made boards for AMD CPUs that supported SLI. I suppose that they would do CrossfireX as well, unless nVidia blocked it in their motherboard drivers. I don't know whether nVidia has sold any SLI licenses for boards with AMD-made chipsets, or whether there are any actual hardware incompatibilities.

It's a funny market. Intel has blocked nVidia from making chipsets for Sockets 1366, 1156, and 1155. (nVidia was big in Socket 775.) nVidia may have been the largest maker of chipsets for AMD CPUs, before AMD bought ATI. AMD doesn't prevent using nVidia graphics cards with their motherboards, but I don't know about SLI.

If you want some additional entertaiment, web search on the Lucid Hydra chip. (Permits pairing graphics of different manufacture.)

I mentioned which of the latest AMD boards support SLI.

I was writing literally; I meant boards with chipsets made by AMD, like the 890FX.

I'm pretty much out of touch with the AMD side. My most recent AMD CPU ran in an Asus A8N-SLI board (nVidia nForce 4 SLI chipset, Socket 939). It's still running as a hand-me-down.

Sorry, read your post wrong. It is just nForce chipsets that can have SLI and an AMD CPU, but as Nvidia stopped making chipsets the newest motherboard that has it is the 980a, which is just a rebranded 780a.

Hi, can you run SLI even if the PCI-e x16 slots are:
2 x PCI Express 2.0 x16 slots (green @ x16 mode, orange @ x4 mode)
Newegg.com - ASRock A770DE+ AM3/AM2+/AM2 AMD 770 ATX AMD Motherboard

What does this mean and should both slots be x16 to run SLI?
The board is AM2+/AM3 socket compatible but then there is this little issue about the PCI-e x16 slots.

Any ideas?
