P55-GD65 (ms-7583) bios 1.A0 voltage bug

[songokussm]

Motherboard: Msi p55-GD65
Bios versions 1.90 and 1.A0

Upgraded from bios 1.90 to 1.A0 and  I am experiencing a voltage bug. with 1.90 there was no bug.
after flashing, my system became very unstable. Stock settings. Zero over/under clocking.

I launched cpuz. to find out that while running the Intel high v-droop governor (?) when my cpu is under load it will DROP voltage.
idle voltage is 1.232 (stock), when under load it drops to 1.117!!
in bios it is set to 1.232.
idle temps: 30            Load: unknown, crashes

switching the voltage governor to low v-droop method i get:
idle : 1.264            Load: 1.278!!!!
in bios 1.232 
idle temps:  40        Load:70

after some diagnostic work i found the following to be the only solution to work:
Governor: Low v-droop
Bios Voltage: 1.107
Actual Idle Voltage: 1.224
Actual Load Voltage: initial 1.323  then 1.248 then 1.256
Idle Temps: 34
load temps: 55

As i said before, 1.90 worked fine with stock settings. Loaded straight optimized defaults in bios. 1.A0 does not.

Specs:
ocz 875 watt psu
intel i5 750
ocz 2gb 1066 ddr3 x2
intel x25-m g2
msi gts 450 x2

Nothing anybody here can do about it.  Please report the Problem to technical Support:  http://support.msi.com/

Go back to 1.90 in the meantime.  Use the Forum Flasher.
>>Use the MSI HQ Forum USB flasher<<

Songokussm the same issues I reported to support, they responded to me, that my MB is faulty and I should RMA ( did it twice, 4 month without MB ) I prove them otherwise, I had 3MB P55-GD65 with the same issues. Short speaking every MB with ERP=040 is faulty on engineering level Overvoltage like you described, problems with fans on sysfan1 and sysfan2, restore AC on power loss not working correctly and sometimes USB2 stops responding.
My conversation with MSI support ended when they statement that they can`t check if I`m correct because they don`t have MB with ERP=040, so the problem is .... gone  I bet that with bios 1.9 in your case issue still occur but is`t less "visible".
