I found many sites and many forums saying that only a VIVO x800PRO can be modded into a x800XT, but not anyone ever saying why! I was googling to find some more info about, I found this site, there is a guy that succesfully modded a X800PRO NON VIVO into a X800 XT, but he doesn't say much of the process he did with flashing the card! Here the link! http://www.digit-life.com/articles2/radeon/rx800-3.html I'm 100% sure it's not a VIVO, there is no Theater chip, and there is that small yellow connector missing beside the power connector for the video inputs/outputs. Tell me what do u think, is the NON-VIVO also moddable??
