Hi TPU!
I have an HD7850 DualX 2gb. Today when i cleaned it i noticed a switcher right next to CFx slot. I can switch it from left to right and vice versa (tried when it was disconnected from computer). What does that button?

dual bios switch.

Thank you for fast reply.
So, if graphic's bios fails, i have to switch that button? It's like an Back-up?

Yep. Please don't try to flash the bios

Edit: Is that rust?

one you can flash the other one its a backup so is read only in case you flashed the first one with a bad bios.

@DarkOCean ok, got it.
@Jetster, no, it's not. You scared me so i had to turn of my computer to see better. It's a kind of a paint or glue, but is verry thin and now i cleaned it.
