What is this slider switch on my 7950?

post #1 of 9
Thread Starter 
Had just remembered about this slider switch on my 7950. Anyone know what it is for? As far as I know, I have a very plain jane card. You can see the slider next to the Crossfire area. On the rear of the card, it says 1 -- 2. It's currently in the "2" position, as it came out of the box.

This is the one that I have: http://www.newegg.com/Product/Product.aspx?Item=N82E16814127737

7950s have two bios, that slider is to switch between them.

Are they both the same, or is one better than the other?

Yes, usually number 2 can't be flashed and number 1 is flash-able.

edit: sometimes one has more aggressive clocks and/or fan profiles than the other.

Hmmm. I wonder if there are any good BIOS to flash on this card? I have the AX7970 on it with CLU sandwiched in between. I'm sure it could handle some extra heat for extra clocks biggrin.gif

I'm unsure if the card is voltage locked, but sometimes BIOS'es for certain cards aren't available. There are ways to modify your existing bios, heck I've done it with my 7990 and it was straight forward. With certain bios-modding programs you have to watch out if the VRM chip is compatible though, and there are others that are more tech savvy and code orientated. smile.gif

Probably not, although there are manufacturers out there that advertise as a card being voltage unlocked even tough it's by extremely small amounts.
