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.
Sapphire rx 580 bios switch.
Those two separate chips regulate every card s key parameters like fan curve and clock speeds.
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.
Sadly i switched it while handling the card and now i don t know which position is which.
I find the idea of dual bios on an rx580 kind of funny.
The switch only changes the bios.
The sapphire nitro rx 580 limited edition is based on the company s custom pcb designed specifically for this card.
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.
In this third part of our sapphire how to series we want to shed some light on the dual bios feature present mainly in the nitro gaming series.
I tried both but the frequency didn t change.
Image i have a sapphire nitro rx 570 i have a switch button on it its written bios switch waths for.
I didn t know there were any midrange cards that had it.
