What does the hardware switch labeled "1" and "2" on the PCB of my GPU do?

I have a GPU here, which has a hardware switch on the PCB. I can set it to 1 or 2. That is you can switch between 1 and 2.

I've tried searching a bit, but didn't find any answer. I'm probably not searching good enough though, I could probably need a course in "how to search for things". But hey, I might as well ask here

If only we know what GPU you were even talking about at all. :)
Having absolutely no idea what GPU you're talking about I'll just randomly say that "1" position puts the card in "regular magic" mode and that the "2" position is "more magic." ;)

Well it's an AMD Radeon HD 7990 (Sapphire version)

Actually, the "2" position turns all matter in the universe instantly into anti-matter, and all life ends.

So, make sure you back up your important data before switching to "2".

And don't forget: when in anti-life setting, "1" and "2" are respectively "2" and "1". Or possibly "1" and "0", depending on where anti-we have decided to start counting.

True. If it's a British anti-life setting, then 0 is really 1, and 1 is really 2. Better hope it's a good American anti-life/anti-matter setting.

Cool. I want one. I want to switch it.

I think this page may answer your question: https://www.tweaktown.com/reviews/5408/amd-radeon-hd-7990-6gb-dual-gpu-video-card-review/index.html

> "You can also see a little switch that we've seen present on higher end AMD offerings, and it switches between two BIOSs. We'll no doubt learn more about how companies intend to make use of it when we see retail versions of the card in the market. If past experiences are anything to go by, we'll more than likely see companies offer two different speeds - one stock and one overclocked, with the flick of the switch."

So it may have to do with switching it into a mode where you can overclock it.

If that isn't right, you can use this search term on duckduckgo or startpage to see more search results:

Some old Radeon graphic cards had Dual BIOS and you could switch between a high performance one and a "regular" one.

Aha! Performance like in clocking speed as mentioned in the link above here?

Yes. It usually increased clock speed to have a better performance.
