CPU Voltage is all over the place

post #1 of 5
Thread Starter 
My CPU is rated for 1.325V but i seen it goes to 1.4V in games and i don't know why, i cleared the CMOS and it still hits 1.4V even when i manually set 1.325V in the BIOS is this supposed to happen? if not is there a solution? Or am i being too paranoid?

Its really more a matter of the supplied voltage sability from the board and what the cpu needs to pull for power.
Generally there is going to be some fluxuation, its more of a droop in value though usually.
I think what your seeing is an effect of your voltage regulators when they heat up with current to the chip, when the conductor gets hotter it usually allows for more current.
High end boards have better components and better voltage regulation to keep this under control.
I wouldn't worry about it at all as long as your cpu temsp are fine .

yeah temps are well within the limit idle is around 21C and load is 32C.
will adding mosfet cooler help with this?

I wouldn't bother, Why not bring the cpu clock up some though? Its already supplying good amount of voltage and your temps are well within limits, just keep it under 55-50 c load and you'll be fine.

lol i took your advice

I unlocked the 4th core and OC to 3.25GHZ with the same voltages seems fine 99% of the time if it isn't stable it will freeze but it seems fine been running prime for about an hour and haven't had any issues
