Sapphire 7950 Boost BIOS

That card should have dual BIOS already. Check near the crossfire connector for a switch. The back of the card will have a 1 and 2 stamped on it. One BIOS is boost another is no boost.

Unless they altered the design at some point. The images I found all show the switch.

Not sure if you can flash back or not. Possibly no longer compatable anymore.

I tried a slew of those. They all lead me to bluescreens or did not even post.

I know about that. They both contain the same bios for me.
 
Just use Afterburner to set the voltage and clocks you want...better than messing with BIOS flashes. I have a HIS boost version and use Afterburner for that exact purpose.

I have that done right now. I would still like to be able to find suitable voltages that's lower than 1.25 for an overclock since that produces high temperatures and is wasteful in my opinion. Hopefully someone has a bios from before the boost came out. Thanks everyone so far though.

You can download Trixx from Sapphire it will lower your voltage. I lowered mine and settled on 1.01 on my Sapphire stock no problems so far at that setting. I even ran it at .99 and no problem but decided to go with 1.01 as .99 seemed kind of low from my research so decided on 1.01.

I have the original Sapphire 7950 OC, no clue if its BIOS would work on your card though.

Well we have dual bios so I would love to try. Do you mind posting it? GPUz should easily capture the bios. Many thanks.

Are you sure you have the boost version? All I can see in trixx is that power control setting.
 
The 2L is voltage unlocked. Hopefully you didn't break that somehow with a bios flash 😀
