The switch only changes the bios.
Sapphire rx 580 bios switch.
Generally speaking with dual bios cards.
Default position is stock it has slightly lower clocks and more conservative fan curves while the second bios usually allows the card to have more juice.
Image i have a sapphire nitro rx 570 i have a switch button on it its written bios switch waths for.
I recently got the rx 580 sapphire nitro se there is a bios switch in the back and online it says there is a gaming and a silent mode.
I didn t know there were any midrange cards that had it.
I find the idea of dual bios on an rx580 kind of funny.
The sapphire nitro rx 580 limited edition is based on the company s custom pcb designed specifically for this card.
Users are able to switch between two modes quiet and performance the first one has a lower clock rate and allows to optimize the fan curve settings.
Speaking of visual aspects the most obvious difference in comparison with the nitro rx 480 is the rx 580 s unique design with a gunmetal gray shroud that looks incredibly good.
I tried both but the frequency didn t change.
Sadly i switched it while handling the card and now i don t know which position is which.
