Are these CPU voltage changes normal?

[plion]

It's set to auto:1.35 in the bios, when im in windows and run ntune monitor the voltage is 1.35 or 1.34 forgot the exact number. Now I was playing the fear demo and alt tabbed and ran the monitor again and the voltage is 1.55. It hasn't dropped and I quit the game and closed/open the ntune program again. Is this normal? My power setting in windows is set to home/office and I have the X2 driver installed...

Ok, it's still set at 1.55 im gonna restart and see what happens, btw I'm NOT running any of the bios overclocking programs, nor in the bios

I think you have cool and quiet enabled, which lowers your votlage when Idle. Maybe... you have all your voltage options at stock?

 

[plion]

No I checked in the bios and its disabled, but Cpu-z shows the voltage as 1.34v while ntune still shows it as 1.55v so I don't know whats going on

 

[plion]

Well in the bios the voltages are set to auto, I can manually set it, but I'm not sure what's the stock voltage for my proc?

stock for the X2 3800+ is 1.35 or 1.4. just set it to 1.35.

k thx, is it normal to see it change though? In cpu-z it moves every so often to numbers like: 1.328, 1.376, 1.344, 1.360 is this normal? Sorry for the newbie questions...


-Update: Ok I set it to 1.35 in bios and now it's listed as 1.344 in Cpu-z but it doesn't change around anymore so I guess thats good.?

It is variable voltage on purpose. Its supposed to be variable from 1.35v to 1.4v or so. Mine does the same thing and all x2 cpu's should do that. I do not remember for sure but all Venice based cores, whether single or dual core does the variable voltage thing. So, definitely do not worry about that

ok thanks, one more question, if it doesn't do that is it still ok? because I set it manually to 1.35 and its always 1.344 solid in cpu z?
