More different voltages modified for reference 6950/70 cards.
People cross-flashing 6950 to 6970 increase memory voltage and this is why it is recommended to unlock 6950's BIOS, right? So we should be definitely able to adjust that and give cards more MVDCC (Memory Core Logic Voltage).
MVDDQ modification (Memory Voltage supplied to the output buffers of the video card memory) is probably impossible, but I could be wrong.
VDDCI (I/O bus voltage) was modifiable for 5870 using RBE (it was mistakenly called vMem). I believe we might be able to control that on rev1 6950/70.
Next, let's have a look at MSI Lightning's BIOS. 6970 Lightning's BIOS features 2.5x PowerTune Range and 2000/2000 Overdrive limits (in M position, perhaps the card has three BIOS chips?).
We gotta be able to retrieve both and benefit from it for our rev1 reference cards. And no, I don't like the software method, re-doing it after reinstalls is not fun. :\
