I've flashed three of my HD5770's and all of them are working on 2.5 GT/s. There seems to be many people running these card as 5 GT/s.

I've seen this thread but it's seems to be scary: https://forums.macrumors.com/threads/1547340/

I was only able to get 5 GT/s by Crossfiring original Apple card with flashed one ;)
 
As I recall, there's a resistor on the PCB that needs to be removed. I think a search at Netkas may help you here.

Just looked at your posted link. And, yep, it's the resistor mod.
