X800pro Flashing to XT

Is it possible to flash the bios on my Sapphire X800 Pro to open up the other 4 pipelines?

if its a VIVO, possibly

if its not, no.

Ok its not a VIVO so its not going to happen.

I have successfully opened up the extra pipelines on two non-vivo X800pros. You just have to reconnect a laser cut bridge on the packaging next to the GPU die, then flash the card. It's not that hard.

How did you reconnect the bridge and which one was it?

It's the only bridge that is cut. I took a needle and lightly scratched away the coating on the two copper dots. I cleaned the area off with isoplopyl and let it dry. The I painted (used a toothpick split length wise as a brush) a line of copper paint (from a rear window defroster repair kit) around the laser cut (if you get any in the laser cut it shorts out) connecting the two copper dots.

beware that hardmod isnt particularly sucessful, ive only seen it work a few times, it must be by pure luck you got 2 to work.

and most later X800pro's had their pipes cut with lasers so they almost definately wont work.

Luck of the draw. Still, it's easily reverseable, so there is really no downside to trying.
