V core Drops under load

Just playing with my overclocks a little and found that with my vcore set at 1.35 when under full load (prime 95) the vcore drops from approx 1.38v idle to 1.32v under load.

My first question is how acceptable are these voltages for an everyday overclock?
And my second one is is the drop in vcore preventing me from going further with my overclock?
And lastly what is causing this drop should I be changing something or is it safer this way?

System spec in signature, your help would be much appreciated.

  1. 1. Voltage is fine

    2. vdroop will cause instability

    3. Google vdroop
  2. Hello,

    If you have Load-Line Calibration in your bios, I'd activate it. It often helps with Vdrop.
    Also, what Vcore have you set in the BIOS ?
    What are your temps under full load ?
    Are the CPU power saving options activated in the BIOS ? C-state and etc ?

    What's your PSU ? If it's a cheap one, then it might explain your Vdrop : it can't provide a stable voltage.

    EDIT : *I can't do more without having your exact system specs.*
    Your signature does not appear with your post, I had to go and check into your profile.
    Your PSU model is not in your signature. If you could provide it, it would be helpful.

    Good luck,
  3. al360ex, it is vdroop, not vdrop. Some is normal. In fact, it is a normal design feature of the motherboard power regulator. It is not caused by the PSU.

    Marc, .06 volts droop is a little high, but not excessive. If your overclock is stable, don't worry about it.

    Oh...I guess I learned something today. Thanks !

    But if the OP has a cheap PSU, sometimes under high load the 12V rail can become unstable and thus cause voltage instability.
  5. Agreed, but vdroop is not a sign of voltage instability.
