Dual Bios is a feature of Gigabyte MB's........ not sure if any other MB manufacturer's offer such a feature.....
the pic, Spikes posted, looks like it is a Gigabyte MB, with the Dual BIOS and the UltraDurable 3 2oz copper PCB's.. these MB's are HEAVY to the feel from the added Copper in them.....
hope that helps......
on an added note: My Mom recently upgraded her PC, and she has a Gigabyte MB, the strangest thing was in the MB Installation manual it said to run the Matched Memory in "Un Ganged" Mode for better performace in stead of running it in "Dual Channel" Mode........ I thought that was backwards, have not had time to confirm it yet......
Yup Gigabyte UD3P. She's heavy alright. Love this mobo to death.
thought I read somewhere that you had to disable V-sync in crossfire..is that correct?
I think so but if you do, I haven't done it manually. Last timne I checked AH it was enabled...ie my FPS is maxed at 60.
