Sapphire 7950 Boost BIOS

[Lean L]

I have this card: http://www.newegg.com/Product/Produc...82E16814202006

I have tried flashing many different bios to this in an attempt to remove the boost feature as well as the severe overvoltage applied when gaming. Does anyone have a pre-boost version of this card? Can I trouble you to send me a dump of their bios?

Thanks

You could look here http://www.techpowerup.com/vgabios/

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

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.

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.

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

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.

I have the Sapphire 3L boost 850/925.

It doesn't have that setting for me from what I recall. Doing some preliminary reading it seems like I may have to unlock the voltage somehow.

I would still like to try the non-boost bios for comparison but I'll report back with best results when I get back to my PC and can test the two different methods.

@Lean L:

I have a 2L -- have you tried Trixx 4.4.0 beta mod? Allows for gpu / memory voltage manipulation.

I really hate where they are going with these locked voltages lately.

Probably not selling enough 7970s

Thanks, I'll be sure to try that first thing when I get access to my 7950 PC again.

Can you upload the BIOs when you get the chance? Much appreciated.

The 2L is voltage unlocked. Hopefully you didn't break that somehow with a bios flash

They aren't.

Don't risk without being sure

Dual BIOS. I've flashed many bad BIOs before. They restore pretty easily as long as you know to never flash the second BIOS.
