[SOLVED] what is this switch on my gpu?

[saySIKErn]

So I took my PC out to clean it a bit and as I was putting the components back in one by one, and I noticed this switch on the gpu while cleaning the backplate.
I have to mention that it is in its initial state now, I haven't moved it but it makes me curious.

I tried to google about it a bit and some people say that is a 2nd bios for mining and other say is a "BIOS clearer" just like the CMOS jumper on the motherboard (but I doubt that).
the gpu is an XFX RX 580 XXX GTS 8GB (quite a couple of X's I know).
What is the best position to have it on? Left or right (I'm asking performance wise)?

It's a dual-BOIS switch. Set towards the power connectors should be the higher clocked/power BIOS and to the left, a "quiet" or sometimes even referred to as a 'miner' BIOS.

[SOLVED] - XFX RX 580 stock switch position

Hi , I have a XFX RX 580 but I bought it in second hand so I wish to know from someone who bought in new what is the stock position of the swtich of the bios ?

So I'd get the most out of it with the switch on the right side and not on the left side you say?

Correct, at least based on what I can find.
You could always try both positions and measure performance/clocks etc, no harm.... but looks like to the 'right', towards the power connector is "stock" or "gaming'
