7800GT 20 pipes. Unlocking last 4 pipes?

[tbz_ck]

Hi

The GT and GTX share the same common base except for default clocks and number of pixel pipelines (20 GT, 24 GTX)

I've noticed in Rivatuner an applet that allows unlocking of those extra pipelines, but I really don't understand what the applet is telling me nor how to unlock the extra 4 etc.

So firstly is it possible.

2ndly, Has anyone succesfully done it and if so, can you give me a run down of how within rivatuner please?
