Crazy voltage fluctuation

[Jinto]

I am OCing my E6600 and am at 350x9 with 1.45vcore. I ran Orthos, coretemp, and cpu-z. The computer was running fine however I noticed that in cpu-z the voltage fluctuates between 1.432-1.448 which sometimes dip to 1.213. Im wondering what can be causing this? I have an Asus P5W mobo and Hiper 4K580. Both are pretty decent components.I checked speedfan and the voltage goes from 1.42-1.45

amost anything from the commercial AC voltage changing, your fridge cuttin on, power supply a little weak.

and the voltage goes from 1.42-1.45

That is nothing, forget about it.

dip to 1.213.

a bit more interesting but as above difficult to say.

without some fairly sophisticated test equimpment and monitoring you will probally never find it and if you did you probally could not do much about it other than buy an expensive Power Conditioner, or a way overspeced power supply.

I do believe it is the speedstep technology built into most Intel Processors. It varies the voltage and core speed of the processor in an attempt to save power / cool down.

I think this can be disabled (?)

I disabled all throttling and thermal control before I started OCing so that shouldnt be the case. Im hoping it is just some glitch with cpu-z since speedfan seem to report a fairly steady voltage. Anyway was hoping to do like 3.4-3.6ghz on the chip but If I go above like 3.2 I will need massive voltage hikes which I dont feel safe doing. Oh well 800mhz OC isnt bad at all

na, i would belive CPU-Z i have found it to be the best..

also hyper isnt really a great name psu. this sounds like an underpowered or when i loads it isnt as efficient.

i would get a forton, antec, OCZ, mushin or Power and Cooling and stay away from anything called turbo, hyper, superfast, ultra, stuff like that

cpu-z sucks for voltage reporting imo. dmm is the only way to go when it really matters
