I thought the only way to get BIOS is through techpowerup? Could someone link me to where I can get a BIOS update for my Sapphire Dual-x 7950? It is the 2l version. Not the 3l.

Also no I don't have multiple monitors.

Did you install a modded bios or an official bios?
Also, I'm pretty sure Sapphire should have the official bios?

I ended up saving the BIOS from BIOS 2 because I didnt name my .rom files correctly and couldnt find the original. So I'm hoping that I didn't flash the 2nd BIOS on the Sapphire with something else by accident. Also, I'm not sure what a modded BIOS is I thought that Techpowerup just had all official BIOS's. I'm pretty sure my Sapphire has the correct BIOS on it though because my clocks are showing 925/1250 which is the clock speeds of my particular card. Something is seriosuly wrong here. If I did a clean install of windows and I still have the problem then it has to lie within one of the cards, right? It was working the other day. The clocks were jumping but the 2nd GPU definetly had a load on it. Now the 2nd GPU has a 0% load on it when in benchmarks which is not right. The problem lies within the crossfire set-up itself. My Bus speed on the bottom card is now stuck at 1.1 instead of 3.0. Should I update my BIOS? I havent updated it at all. Could my new PSU possibly be at fault?

I haven't uninstalled the drivers yet since I did a fresh install of windows. I will try that, but if I installed the drivers after a fresh install of windows and still had the same problem, then wouldnt the problem lie within the cards themselves? or the motherboard? Since my bus speed on the secondary card is stuck at 1.1 instead of 3.0?

I also did disable UPLS and that didn't help. I followed the guide on the "AMD How to thread"

From what i can understand your second card just stay at idle.

Try to reflash the stock bios. Different bios can mess up because the stock voltage is different for each card.

Also can you tell us your psu?

Try to change pci-e lanes.

Install the latest bios. Change your cf bridge. You have 2 cards so use the second one

My PSU is a Seasonic x 850

What do you mean by "change the pci-e lanes"? I only have 2 pci-e 3.0 lanes and I have already tried switching the cards around and it still didn't work. I re-install the drivers after trying that.

How can I find the latest BIOS? I'm having trouble finding it and telling which ones are for my card. I have an SAPPHIRE 100352-2L Dual-x 7950

What do you mean by "change your cf bridge you have 2 cards so use the second one"? I only have 2 cf bridges. One came with each card. I have both of them attached. That is how I'm supposed to do it, right?

It would be this one, right? my stock clocks are 925/1250 and this matches up, but nothing actually says my model number or "dual-x"

http://www.techpowerup.com/vgabios/127996/Sapphire.HD7950.3072.120816_1.html

I'm pretty sure this is the BIOS that I already have flashed on my card.
