990fx extreme4 reset NB voltage after suspend mode

[purple1]

Hi all


Regardless of any settings from bios (auto or manual), when I exit from sleep mode the CPUNB voltage is Reset to default values.
The others voltage are fine, only the CPUNB is affected.
The only way to avoid this is to disable suspend to ram from bios but this is not the sweet spot.


My specs:
asrock 990fx extreme4 (Bios rev P.2.70)
AMD FX 8370
RAM gskill tridentx 2400 16gb
Win10 pro x64 Creators update with all updates


Thanks in advance for reply.
