Question regarding CPU voltages

Last response: in Overclocking
Share

Just to make sure I am right before I blow my q6600/p5q se2 straight to hell...

If I set my cpu voltage in my bios to 1.575v...
I get roughly 1.47v in windows using CPU-Z, HW Monitor and Asus Probe
The bios hardware monitor reads it at around 1.46/1.47v

That means "in theory" I am not going to blow my poor little baby up? (its a q6600 with go stepping good for 1.5v)


*C1E/speed step are not enabled*



Basically should I go by what I set it in the bios or what it is in windows/bios monitor?
Im 99% certain the windows load out is correct but cut me slack...setting your bios to 1.575 is flipping scary haha



EDIT: Sorry should also mention it does this at every voltage...
I set it to 1.5 it shows up 1.42ish
I set it to 1.3 I get 1.22ish

No you are correct the voltage setting in BIOS wont be identical to the actual voltage in windows. And the windows reading is what I would go by. Some motherboards are better at maintaining constant voltages than others and some BIOS settings help to with that as well. A multimeter can be used on some motherboards to accurately measure voltage from the motherboard but thats more technical than your question needs (and more than Im experienced with atm).

Yeah the thing is this board doesn't (or at least I am unaware) of an easy access point for using my multimeter. I've seen boards with nice lay outs with labeled spots for using one but yeah other than emailing Asus I really have no idea where I would take the measurement. I am not that tech savy (CJ major haha)

im with you. lol, but i dont think i really need to anyway. ive overclocked my 920 to pretty high levels with pretty radical differences in voltage between BIOS and windows and done alright. I think its useful for overclocking fanatics anyway, but not for me.

Ya some boards make it real simple to use a multimeter but it wasnt worth the extra $ from my perspective.

A lot of crappier boards (ie my p5q se2) dont regulate voltage well. In order for me to get 1.5 (which is the max voltage for q6600) I need to set it to 1.575v. The only reason I created this thread was to make sure I was right that its the actual voltage that counts because as you can prob tell 1.575 is a lot to throw at a cpu. Id much rather be safe and ask a dumb question then go out and drop a couple 100 on a new board/cpu/ram cause when this set up dies Im going i7

Yeah this is absolutely the worst motherboard ever...

1.58 set in bios
1.48 in windows/bios hardware manager
1.4 on load

:)  Yup my board can swing upwards of .2v :) 
See why oc if it wont be a challenge hahha

I have a question to though on this. My vcore on my PhII is set to 1.55v right now and at idle I will run about 1.54v under load it will get as low as 1.42v. It runs stable and all, but it there a way (like CnQ or something) to get it to lower the idle voltage, since it seems pointless for the volts to be so high at idle.

Yeah make sure speedstep and or C1E is enabled in your bios and it will help to lower your cpu speed and voltage during idle times

not all boards have it if im correct. but have you tried to lower the voltage to see if you could get it stable at a lower voltage then 1.55 just drop it alittle and test for stability and keep lowering it til it is not stable anymore might even get the voltage down to 1.4 or so
hoped this helped
