vCore Fluctuation

post #1 of 9
Thread Starter 
simple question:
vcore in bios is 1.275.
cpu-z reports 1.264. (@idle)

what gives?

This is called V drop. See what Cpu-z says under load.

i thought vdroop referred to vcore fluctuation between idle and load?

It does however your bios settings are not going to be 100% effective and even under load you may not actually reach the setting you placed in the BIOS.

Also software such as CPU-Z is no where near 100% accuracte in reporting your Vcore.

i see...
so is this a misreading with the mobo or cpu-z?

Either or both unfortunately, I am sure there is extremely expensive equipment that could tell you with almost no error, but does it really matter?

it doesn't, but i am just curious as to whether my cpu is receiving 1.264 or 1.275.

but as mentioned it doesn't matter.
+rep and /thread

Yeah the problem is which do you trust to be accurate. I always side with hardware manufactures and would say your bios is more likely to be correct. If you look in your Bios it should give you an actual based on your settings.

Basically save you bios settings and then when you reload the bios go by those voltages(although they can be affected by vdrop). Might want to enable LLC and see what CPU-z says then as well.

Thats electricty for you, unreliable at best

What you are experiencing is Vdrop, or Voltage Drop, and is normal. .011v isnt too bad either. Vdroop, which is something completely different would be your Vcore voltage during load.
