GA-P67A-UD4-B3 - DRAM Voltage/QPI/Vtt Voltage/System Agent Voltage

[NiklasA]

As I understand it, if you set DRAM Voltage to 1.64V you should also raise the QPI/Vtt Voltage to 1.14V to keep the max 0.50V difference between the two?

What about System Agent Voltage, should that be raised as well (I can't find a definitive answer anywhere)?

theres different opinions as to whether the .5v rule applies to sandy/ivybridge for p55/x58 then yes it applies,system agent doesnt need to be touched imo

for sandybridge the max intel safe limit for dram is 1.5750v but ive seen folks use higher without issue,qpi/vtt max safe is 1.2v though you shouldnt need any higher than 1.1v
