Hmm, since both technologies (ULI M1695 & Crossfire) are finally out, has anyone attempted to put an X800 AGP card with an X800 PCI-E Crossfire card? If so, what are the results. I've read that's its theoretically possible but i'm wondering if there would be any drawbacks. If anyone could shed insight that would be nice.

P.S. i mean without flashing the BIOS, that's why i didn't ask about SLI...

Does AGP crossfire support any standard AGP card on its own?

I don't believe their is actually a card that is the crossfire master card on AGP. What i meant to say was has anyone tried using their AGP x800 card with their PCI-E master card on an ASRock 939Dual-SATA2 board.

dude you're an idiot. THE CROSSFIRE BOARDS AREN'T EVEN OUT YET!

crossfire does not support agp anyway (i'm 90% sure)

I don't think AGP Crossfire is possible. I beleive that SLI and Crossfire require the two way communication that PCIe provides. If it was that easy, we would have probably seen dual AGP motherboards a while ago.

Dual AGP is impossible, the standard is limited to one slot...but since the data is being sent over the external dongle and not the bus like SLI (correct me if I'm wrong here) this just might be possible.

yea... thanks for that... (a$$..) besides, who the hell said anything about the crossfire boards in the first place? Read more before you flame, I was talking about the 939Dual-SATA2 (hence the ULI M1695 in OP), not the crossfire.

And to everyone else, thanks for your input. I didn't realize that Crossfire used the PCI-E connection to speak from card to card. My understanding of crossfire didn't include anything using the bi-directional...ness... of the PCI-E slot.

(edit: actually my idea was much like

Newegg has had X850 crossfire masters for about a week now.

now show me a crossfire mobo for A64...


can anyone confirm that running AGP AND PCI-E graphics card works on the Assrock Sata2? I doubt its possible...

If you read the Intel spec pages on AGP 3.0, it says you can accomadate two devices on the AGP bus. PCIE has more bandwidth and scalability. Seeing how Intel drives both AGP and PCIE, you'll never see a SLI AGP option. As SLI PCIE is a much better long term solution.

Well, i believe the whole point of the "Triple Graphics Interface" was to be able to use AGP, PCI-E, and PCI at the same time. Under these circumstances my understanding is you can have multiple video outputs by using this. What I'm wondering is whether you can use the TGI to use Crossfire in a similar fashion because of its external dongle thingy.

beautiful, this is what i was looking for, so it IS possible. I'm not sure if they did anything special to reach it due to... linguistic difficulties... but just the fact that it is possible makes me happier (just got the ASRock and was hoping that later in my computer's life I can upgrade to Crossfire). I'm sure eventually Anandtech or someone will have some kind of review about this explaining it thoroughly. Thanks so much.

I guess you did not read the new forum policy? Here, let me link it for you.

So... people are just imaging that they are capturing video with their AGP ATI AIW cards?

Ahhh, some driver trickery was all it took, kinda like how Nvidia keeps SLI to "approved" platforms only.

Good point...

Though when you take a look at the score differential, I would be hard pressed to get an AGP card(or not sell it for another PCIE version), when the dual PCIE setup is putting up much better numbers.

AGP 3.0 Look at section 3.5, there are numerous remarks about more than one device. Though you can see they are more or less against it, as the bus is optimized for a single device. The catch all, the System Designer, must accomedate the signally issues that may arise from using more than one device. Again, reiterating the fact that PCIE is the superior solution for multiple devices on the bus, that require synchronization of data.

It's all fine for dual pci-e when you really want the high numbers and you have the $$$ to do it. What i'm concerned about is for those that have the high end AGP cards from the past being put into the Crossfire technology of today.
