Three Video Cards

[JLV2k5]

I've seen some motherboards with 3 PCIe slots. Usually the third isn't up to the same amount of channels(speed) as the other two. Are there motherboards that can handle triple SLI with all three cards running with the max amount of channels? Thanks for the help.

i think two slots could be for an sli setup and the other for a separate monitor perhaps. as far as i know there is no such thing as triple sli yet, and that's the only way you would be able to do what you are talking about.

No. There is.

No. There is.

then why did you post asking the question

 

[The_Beast]

^^^ he was looking for a mobo that supported it

 

[INTELCRAZY]

Just expect to only get ~70% performance increase... Don't expect to really get 3x performance of a single GPU...

I wonder if you could run 3x of the 9800GX2's coming out... I might put 2 of those in SLI...

 

[JLV2k5]

then why did you post asking the question

If you read my thread clearly you would have seen the reason for my question.


Thank you The Beast, for understanding.

Thanks for the info INTELCRAZY. I didn't think you could run the three in SLI all at max but i have seen peoples system specs and some have 3x 8800 Ultras and things like that so i knew it was possible. Thanks

I think that i found a card that can do what you want.

http://www.newegg.com/Product/Product.aspx?Item=N82E16813130080

Its an MSI board with 4 PCI express x 16 that also can use Core 2 Extreme/Core 2 Quad

Specs from newegg.com...

4 (The 4 PCI Express interface will operate at either x8+x8+x16+x8 or x16+x16+x8 mode)

Yeah the answer to my question is this. You can have two cards running in SLI, both using 16 channels and at max. Cool. But the most I have seen for three is 16 16 and the third would utilize 8, so it would be running at 50% of what the other two are. Granted, you would get more performance than having two cards, but it still isnt like beasting three full GPUs. Thanks for all the input guys, great help.

 

[The_Beast]

Hope you know that you need a ultra or GTX to Tri-SLI

The 780i chipset has three X16 slots.

Or HD3850/HD3870.

 

[JLV2k5]

There you go. But technically he was right. You cannot run SLI with the ATIs, it is Crossfire

 

[The_Beast]

Or HD3850/HD3870.

I'm not an ATI guy, so I don't keep up on there stuff

 

[JLV2k5]

That board is a beast. I don't keep up with ATI stuff either, exclusively nVidia.

 

[INTELCRAZY]

Crossfire can take 4 cards but is limited to 8x on all 4 cards..

 

[PunterCam]

I know the mac pro's can be bought with 4 ati cards, but I dunno how they work... Thats not very helpful I know. I'll go to bed

 

[smerk]

Haha, i cant see how much of a difference a third ultra/gtx would make after the second in SLI anyways
