WOW, Flip a switch and it Boosts its speed up by ...???? 0.84%... Less than 1%? (Lets see 1,777 normal boost, 1792 after flipping a switch.. thats 15mhz, 15/1777=0.0084). I looked at several other site.. they all quote the same 1792mhz with the switched overclock. I am wondering if it is Underclocked with the switch in normal to save power/heat load. So the 1,777 might not be accurate.. Random guesses. I do like the Card. It would be great in a mini ITX build.
