Which voltage?

post #1 of 6
Thread Starter 
In the BIOS I will set the CPU voltage to 1.5 volts to start overclocking (I work my way down). In AMD Overdrive in the CPU status menu it says the VID is 1.425v. In the board status menu says it is 1.5v. Which voltage is the CPU getting? Am I allowing the motherboard to let the CPU use 1.5v and only letting the CPU use 1.425v?

CPU-Z is probably the closest to accurate besides a multimeter. Almost all boards have an offset of what you set in bios to what gets applied (ex. 1.4v in bios actually yields 1.38v in Windows, etc...) and then some boards will slightly lower/raise the voltage under load. So don't go by the bios, don't go buy AOD, go by CPU-Z.

CPU-Z says 1.488. Thanks. What exactly is offset voltage then?

VID (Voltage Identification) is the default vCore your CPU needs in order to run at stock. Many programs simply read what this default value is as a reference. As mentioned refer to CPU-Z to read your current vCore.

Just the difference in what you set in bios to what the actual voltage is. Very rarely will a motherboard be spot on, there is usually a slight difference between what is set in bios to what you actually get. Sometimes it's positive, sometimes it's negative it just depends.

I use Cpu-z or HWMonitor. Both work great.
