Hi im trying ot overclock my Sapphire HD5670,but every time i try to go higher than 800mhz on my gpu and 1020mhz on vram i get malfunction.
When i start a game the screen turns black and i need to restart the computer,Ive tried changing the bios of the vga but same thing happens.
Im sure its not heat because i have installed a Zalman VF1000 and it runs on 28C.Please help i don't know what else to do to overclock my graphics card.
