Hello I have a HD4200 IGP (785G chipset) and i was wondering what software I could use to overclock it? I can't use BIOS because it is locked by HP. On both the catalyst 11.6b and 11.8 drivers, AMD overdrive causes a blue screen (although the original OEM-installed drivers does not), and MSI afterburner recognizes but does not let me overclock the graphics clock (when I push apply, the clocks reset). Powerstrip does not make any difference, Rivatuner doesn't recognize GPU, nor does AMD GPU Clock Tool. So I am wondering what possiblities I have left. In benchmarks, I saw that a simple 100 mhz increase in the core clock gives around 2-3 fps in games, and I'm not planning on a massive overclock (from stock 500mhz to 600mhz) and keeping stock voltages. Anyone had any luck? Thanks!
