it's an asus zenith xtreme . it says it supports xfire , with a big logo of xfire . i 've tried with 2 cards instead of 3 . 3 seems to be better . like when i stream youtube the xfire seems to start . i can get xfire in older games too . but i know about the game support , but in the bios the lanes are all pci e 3 x16 . in windows it reports lower lane speeds , is it because my cpu is a 1900 and not a 1950 or higher ?!
also consider my question on the extension board
also my motherbaords' LEDs are always yellow no matter what . they only get white or green for a short
