I' m trying to get highest posible mem overclock on my rx 470. I got timings from 1750 to 2000 in bios and uped max from 2100 mhz to 2250 but it crush above 2190mhz i want to try uping mem voltage by just 3-5% of what it is now in hope of getting stable. From my info voltage in wattman is controler voltage not actual mem voltage and maybe i' m blind but i dont see mem voltage in bios. Any info? Or is it enought to overclock controler if yes how far
