Are you sure about this Achim? Currents are separately regulated and limited. I'm not sure how NB VIDs/Volts affect CPU VIDs/Volts you know, they are totally separate and independent of each other, because the IMC has it's own separate voltage from the cores, decided initially by the NB VID; on the 5 phase MSI RD790, CPU gets 4 phase PWM regulation with a maximum of 110A, so 27.5A in each phase and the IMC gets 1 separate phase for 20A maximum. Both have separate VRMs controlling their supply voltages, and both attain independent voltages. This is why that fella burnt up his K9A2 CF PWM area, it can't handle 110A+20A through the VRMs.
So, if I test 2.3G CPU/1.8G IMC at 1.2V/1.1VID and it fails, moving it to 1.4V/1.1VID or 1.4V/1.05VID doesn't get me any more stability at all, it still fails.
