680 Lightning Voltage Control Issue

post #1 of 3
Thread Starter 
Hey guys, sold 7970 Lightning today and came back to Team Green with 680 Lightning.

I figured this card was manufactured after NVIDIA forced vendors to limit voltage control(ln2 bios was basically like standard, only 133% power limit and 100mv voltage), so I flashed old ln2 bios and got the unlocked control. Since then I started OCing to see how far I can push it and reached very satisfying result of +104 core/+600 memory stable on stock voltage and +200% power limit.

The problem started there. I could not increase my voltage; I checked my voltage while running MSI Kombuster but the voltage stayed at 1.212 whatever I do. Below screenshot I set my offset to +50mV but it still reads 1.212 as highest voltage in record.

Also tried GPU-Z, shows same record.

The Bios version I have now is 80.04.28.00.3a.

Do you know the AB edit you have to do?

Also voltage does not read right in AB from the 680 L.

Don't trust software when it comes to a voltage reading...use a multimeter, and you can see your "real" voltage.
