Re: ASUS Publishes GTX 465 Unlock Tool - Transform To GTX 470
It's not all about the BIOS. It's just in the case of the GTX 465 that they are disabled via BIOS.
I have heard nvidia normally disables features through software storage separate from the bios that is hard locked. Though some have said only 480 cores are visible on the GTX 480 so maybe they were laser cut? Either way nvidia saw it fit to cut those 32 cores to maximize performance. I believe it was said that removing those cores allowed them to set the voltage in a way that they were able to squeeze out some extra performance.
