3 Sli on 8800GT with P5n32-E n680i - With no Bridge connector? Possible?

I will have some 8800gt and would like to dish out 3 8800GT without the connectors.... as it is possible to install it... would it be detected as 3 Sli? :D

Yes buy three cards... bridge two together and the third one can be placed in a nice parcel and sent to my home address.

If you mean 3-way SLI, no not possible, you need the bridges and only the GTX and Ultra models support 3-way SLI.

I think it sucks since it would have been a good way to increment a system's power over time with lesser components... buy a 8800GTS now, add another in 6-9 months and another one 6-9 months later.... too bad.

I still don't understand why Nvidia doesn't allow Tri-sli with 9600gt, 8800gt, 8800gts. . . Pretty ridiculous to make the minimum amount of money to use Tri-sli at around $1300 just for the graphics card, and how many people actually play at the extreme resoulutions that would actually see benefit from three GTX or Ultra cards?

It's not a software limitation, it's that no other card has the required 2nd SLI connector on top.

It does work its been tried, you can use 3way sli but without any bridge you sure as hell wont notice a difference.

Probably because without the bridge, it's only considered 3 separate cards, not 3-way SLI.

I didn't say you couldn't plug 3 card, I just said that without the bridges, it will only be considered 3 separate cards; no performance improvements.

You can put as many cards on a motherboard as there are slots.
That does mean you end up in SLI though.
There are ONLY 2 video cards that will run in 3 way SLI.
8800GTX, 8800Ultra
It's pretty pointless anyway.....

The new 9800GTX will permit 3-way SLI.

It will not be much faster than a Super Clocked 8800GTS and the MSRP will be $299-$349.

You dont need the bridges to run SLI jsut the compnents and the drivers.

 


Anyway you miss the point with the new GTX itll run much cooler take a lot less power and scale much better. Tri-Sli ers dream.

[:mousemonkey:2] Are you sure?, because my GT's will only run in Sli with the bridge in place.

I googled a bit trying to find something that would prove bridgeless SLI wasn't possible, but what I found was the opposite! The bridge seems to be used for extra communication bandwidth between the cards and nothing more. Without them, the communication has to go through the PCI-E bus.

I found a couple of articles on the subject: this one or this one (whole thread and/or the post by jpebcac).

Since going bidgeless has it's cost AND going from 2-way to 3-way gives a limited gain, I wouldn't be surprised if, in the end, 3-way bridgeless SLI would be about as fast at a bridged 2-way SLI.

As mythbusters would thay: myth plausible (from what I gathered so far).

That was my understanding although I never tried running it without the bridge.

But I don't think the GTX's are even available yet, and when they are available, what price will they be, how will they scale when adding a 3rd card, (I don't think it will be any better than the 8800gtx, which proves that a 3rd card in SLI right now just barely does anything for performance. I could be wrong though. However, since you can't buy them yet, no one knows for sure.

Cards like 8400GS in SLI because of their low power means they dont really gain from the bridge and can be used in SLI with just the pci-e slots.

 


Tri-sli 8800GT is possible it just wont get anywhere.
