Hi, I followed this tutorial (its french . so use google translat ^^) : http://www.overclocking-pc.fr/forum...ATI-sous-windows-%28HD-3xxx-4xxx-5xxx-6xxx%29 and this one : http://www.overclocking-pc.fr/forum...bloquer-les-fr%E9quences-sur-HD57xx-et-HD58XX so I flashed my CG small problem. the flash is active in the BIOS of the CG but not in practice (under windows / 3D Games / stress tests) here are some pictures: BRE : GPU-Z CG idel : GPU-Z load (stress with furmark) : you can see in this imag that GPU/Mem frequencies and vcore are still the base ones = flash is not active ! [:huh:] did I miss something in my flash? and if i flash it with asus BIOS will i get vcore control ? if yes ! can i have a link to a working bios thank you !
