Sapphire 4870 1gb toxic bios?

[Cuboard]

Anyone have a Sapphire 4870 1gb toxic bios please

Hi, I have the non-Toxic 4870 1gb, but looking at the PCB it looks exact same as the Toxic version.
I was looking at a volt mod but none available for the card I have, and Rivatuner soft mod via registers in not possible on these cards.
So I'm thinking of a BIos flash to the 1GB Toxic bios, hoping that maybe the Toxic Bios has higher voltages. (though I imagine they're the same)

SO anyone have or know where I can get hold of the bios?
Also if anyone has seen a vcc volt mod, would be handy.

Many thanks!

You should be able to increase the core voltage in the BIOS using RBE.

Thanks, I have checked, but my Bios has the voltages set at the highest it can go 1.268v IIRC.

Edit here's a pic or RBE

Just hoping that maybe the Toxic bios has somthing different, but I think it's a long shot.

Looking at a review of the Toxic, it didn't overclock at all.
I have used my old 3870 heatsink a HR-03, and temps never get about 49c. Although I cannot fit any RAM sinks at the Heatpipes get in the way. But the core should fly with a few extra volts.
It does 850 easy, but any more and the card resets via VPU Recover.

Well got hold of the bios, but it's the same as mine, just higher clocks.
Attached if anyone else can use it

I have the Sapphire non-Toxic 1GB 4870. Whilst I haven't tried, I understand that you can't do anything to alter the BIOS voltages in Rivatuner or RBE. Again, as far as I know, the only way to increase voltages at present is to hard mod the cards.

Though, I cling to a glimmer of hope that some genius will come up with a way to increase voltages by other means...

EDIT: ive just seen there is a new release of RBE now, would that have any benefit for people with previous unchangable voltages?
