I don't know if you have done this:

1. Save the BIOS from position #1 & #2.

2. Use RBE if either one of the BIOS will allow you to edit the voltage register as in my previous post. If it doesn't, it's either the Sapphire doesn't have Software Voltage Control or not supported by the latest or any earlier version of RBE.

I'd suggest stick with Trixx in conjunction with PowerSettings +20% to achieve the highest stable OC. The PS +20% should allow you to draw more power to sustain higher clocks.

Other than the above, flashing with 6970 is not recommended as it might have different VRAM timings not compatible with your Sapphire. It also will not give the voltage control if the hardware doesn't support it. If so, the only option left is voltage hard mod. I haven't seen anyone did it but could be wrong here.

On stock air cooler, the stock voltage +20% should give you a very nice clock.

Yea agree with the above and Afterburner will not support non reference other than MSI. I don't know if you have tried Asus Smart Doctor, if so Trixx is Sapphire own product must have the voltage option if the card voltage is adjustable.

Seriously ? what are you doing ? dude, simply put you have reached the LIMITS of your card / GPU chip ... it's really that simple, in your quest to push it and overvolt it to reach that extra few MHz you run the risk of completely frying the PCB board and having a $250 paperwieght on your hands, I'd suggest you stop and be happy. You actually have some great OC numbers, especially for a DIRT3 card, heck even the TOXIC's and true HD6970's barely reach 1000 MHz and they're designed to attempt this, your DIRT3 card isn't. Don't get greedy about 1000 MHz and risk ruining your card dude redface.gif
