Maybe its just to increase the core/memory to go higher,anyway remember 6800GT bios volt mod from 1.3v to 1.4/1.5v to make it behave like 6800Ultra's could be the same thing. We won't know unless someone tries so will have to wait and c who the braves one wanna try it on their 7900GT's

The 6800LE doesnt involve any hardmodding at all
It's purely softmodding, so depending on your luck you might get an extra 4-8 pipes, or you might not

This guide, i assume involves hardmodding physically

So what do you gain actually with the extra voltage?
Some extra overclockability i assume?

Did u use nibitor for bios modding or did u do a hard volt mod?
