Sabertooth 990FX and CPU/NB voltage problem

I set voltages to Offset mode, and lowered CPU by -0.1V (1,380V).
All went O.K., but when I try to decrease CPU/NB (clocked at 2800 MHz) by one step only (-0,00650V), voltage drops to 1.150V, a pretty good value but too low to have a stable system (PC crashes or freezes or hardware error detected in Prime95). If I leave CPU/NB Offset to Auto, voltage is absolutely too high (1,450V).
How can I set it to reach 1.250 or 1.300 V?

If you take a look at my signature, you'll see that BIOS is already at r1503..

This is and old video http://www.youtube.com/watch?v=5a7AxZJ7tWc but could help you. Looks like you are really pushing your cpu/nb to the max for a 3.4 why not lower it and raise your multiplier? With 16G ram if your are using 4 sticks try 2 not as much load.
Good Luck and God Bless Johnny333 65+++
