MSI Afterburner + Dual 5970s

Ok, this might not be quite the right place to ask, but worth a shot.
Does anyone have any experience using MSI Afterburner with two 5970s?

The reason I ask is due to this

That is the information area for Afterburner, notice how the master GPU is missing the driver version
and memory count? Normally I wouldn't care. But the problem is that Afterburner can change the
voltages on all 4 GPUs... except that one. I can use the XFX Overvolt tool, and it does indeed change
all 4 GPUs, but that tool has no command line parameters so you cannot get it to change the voltage upon boot.

I could probably mod a BIOS to up the voltage, but I would like to avoid it unless neccesary.

mmm i had no problems i uesed this version

are you uesing gpuz to see if voltage has changes if so make sure you stress the gpus as not stressed they lower voltage

Using 2.2.0 beta 2, so newer than that one. And yes, I use GPU-Z to check, all but one of the 4 GPUs jumps to the correct voltage when stressed. I eventually just got the stock BIOS for them, and flashed them with a higher voltage and that's worked.

very nice

look at this click link 3rd bios down very good results with it

I overclock on my own, no sense flashing something like that if it's too much for my cards.
