ATI's Crossfire link kører åbenbart over en SIL1161 chip, dette har sine ulemper. Læs om det her:

Earlier today I was given information regarding ATI's upcoming Crossfire technology that, at first, I passed off as so ridiculous it couldn't possibly be true. However, after having the information verified from several very reputable sources I've decided it would be a disservice to keep this information private.

As many are aware by now, ATI's Crossfire technology uses an external link to connect the Master and Slave cards together (it's sort of like a 3-headed dongle with DVI connectors at the ends). What's not generally known is that the backbone for this setup is a Silicon Image SiL 1161 chip which is installed on the X8-series Master cards. The SiL 1161 is there to receive output passed over the external link from the Slave card in the Crossfire setup and pass it on to the Master card.

Sounds decent on paper and everything, but if you check out the specs for the 1161 on this page you will see that it is limited to single-link TMDS @ 165MHz. This means that the max 3D resolution for any X8-series Crossfire setup is 1600x1200 @ 60Hz. That means no high-res Crossfire gaming beyond 1600x1200, no 1600x1200 at a flicker free refresh rate, and no widescreen 1920x1200.

How can a technology so clearly aimed at enthusiast gamers have a limitation like this? High-resolution flicker free gaming is one of the primary benefits a multi-graphics setup like Crossfire should offer entusiasts but, somehow, ATI managed to mess that up completely.

Lyder rigtig rigtig nedern, håber det er et falsk rygte :( - selvom han siger han har fået det bekræftiget, ellers græder jeg fandeme snot!

1280x1024 ville dog oxo gå - men kun ved 32x FSAA :| & 64x AT :P
