For those who want to get past max on CCC,
u need to do a force flash to Asus Top bios to get more than 850mhz core OC on CCC
Of course to get that level u need to add voltage & to have a better cooling too
U can asus Smart Doctoc software to get up to 1.3vgpu (default 1.0vgpu)

here is wat u need :

1. Asus HD47700 Top bios : http://dl.getdropbox.com/u/55589/ASUS4770.zip

2. ATI Flash : http://www.techpowerup.com/downloads/1123d/atiflash360.zip

3. Asus SmartDoctoc : http://www.asus.com/product.aspx?P_ID=Dkru...ZINJ&templete=2
