How many crossfire bridges do i need

Yeah, when the s, s, and s were out I was using two interconnect cables. Benchmarks, especially 3dmark06 scored much higher with one, and since then I only use one. The X2s only have one interconnect rail on the card, so that supported my thinking. I've noticed that the s have two rails, as do the s.

There hasn't been any controversy over it so i'm sure that the s use one interconnect, that is unless more than two cards are used, in which case the 6 rail multi-connector is used.

I haven't seen a 3rail single configuration cable, but then again there is prob. I've always wondered why some people use 2 bridges. I've never had any issue using only 1. I always assumed the cards had 2 connectors so that the 'middle' card in tri-fire could connect to the card above, and the card below. Hence the X2 cards only have 1, because they only support max 2 cards 4 GPU's Is there an actual performance difference that is measurable?

I think the reason is that a lot of reviews when dual cores were the thing were done using two interconnectors. It was also a time of great non-compatability for crossfire. Triple crossfire at that time was called TRiple-Play, and the third card was called a Physics processor. It never took, and there hasn't been true triple crossfire until now with the x58, and other newer chipsets that are out there with the release of the new I7 board line-up.

Speaking of When are you going to join team Quad-Fire?!?! What do you mean by random errors? I have noticed Micro-stuttering, tearing, and performance loss on 3dmark Good to know, as the same question crossed my mind after seeing the pics in the review on TPU which shows 2 bridges on 2 cards I had flickering artifacts with an old CF system using 2 bridges, removing a bridge solved the problem with identical performance.

However I get no artifacts with my CF system with 2 bridges but I still only use Hmmm guess it depends on what cards are used IIRC my 's will not engage crossfire with only 1 cable. I always wondered about this. That's not to say I haven't had some weird :banana::banana::banana::banana: happen before, but I wouldn't exactly pinpoint the dual-bridges as my first suspect. Might be worth some benching with one bridge vs two.

Well I use two bridge connects on my 's and haven't had any problems. I use two because the directions that came with my cards said to use two. Not only did it say to use two it showed photos of the installation and it used two. I know the issue was in XP I started talking mad crap to my mobo becasue i thought i lost another PCI X slot after a ln2 session I would say only needing one derives from OS Might be an XP 32bit thing I actually had 3 of them.

But with 3 cards you need to run a bridge from one to the other to the other. Saaya, Does that mean that you can runn X2 Crossfire with no external interconnects?

Would that be a faster interface? Just home from work The X2 has no external connections. You only need it if you are running two of them. It is all traces in the PCB. THis whole thread is about crossfiring ati cards Hence, by internal connection i'm talking about crossfiring without a EXternal crossfire bridge. He's just saying with a stand-alone X2 all the Crossfiring is done on the PCB with no wires leading away from the card.

Hmmmmm, currently running with both ribbon thingys After work I will have to do a little testing You guys read the HardOCP review? I was actually testing one bridge versus 2 bridge thing on my s and with a single bridge my rig locked up on the first 3d06 test Performance was the same though.

May have been just some random issue but I ran 3d06 like 10 times with 2 bridges with no issues. Saaya I will check, i'm tending to think bios or board used can make a diff as well.
