Hi all,

Does anyone know of an article explaining how the old crossfire worked? I wasn't old enough to be an "enthusiast" at the time and this seems to have escaped me. I understand you needed a master card and a crossfire card but could the be used individually? What were the technical limitations at the time?

Thanks.

found this, and a little bit of extra looking lands me that older cards which are crossfire capable require some kind of extra external hardware (no internal connectors) to achieve crossfire.

Yeah, I saw that through a quick google but was hoping for a serious, in depth technical explanation as to why you had to run two specific types of cards.

i cant tell you, ive never done crossfire, or any significant multi-gpu setup. I tried though.

Legacy Crossfire? Is that Crossfire where you used some card like a 4890 + a 4870 or a 5870 + a 5850?

No, I believe that's called CrossFireX. I'm talking about needing something like a x800 card and then you needed a special x800 crossfire edition.
