Yeah but 1.9v for a split second every 5 seconds or so isnt going to raise temps that much. Plus I have a NH-D14 in a HAF 912 case with all fans on max.

1.5v is going to degrade the hell out of that chip. I'd highly suggest you just stick around 4.8GHz and be happy with it if you can't reach 5GHz without so much voltage.

Even a few seconds at that voltage and temps will noticeably increase. People running LN2 on these are running at 1.6V for reference. 1.9V is MASSIVE.

Yeah still though I feel that the cpu is more at risk from overvoltage than heat. I even get the asus warning software popping up saying "warning cpu over-voltage 1.956v" The spikes go from 1.67v to 1.95v on average.

But then the AMD is 45nm and the Intel is 32nm so I dont know. I read that nothing over 1.4v is supposed to help with sandy bridge but raising the volts to 1.525v clearly made my 5Ghz prime stable.
there is a huge difference between 32nm chips and 45nm... especially when interchanging from amd to intel. Most people say staying below 1.5v is a must. You will experience degradation really quickly... that's for sure.

i would dial it down man... your cpu will not be stable at 5ghz for long

EDIT: if there is a temperature spike at the same time as the voltage spike it tells us that there is an actual increase in voltage... so is there a temp spike at the same time as the voltage spike?

You're not getting it - I'm trying to figure out if there is an increase in heat because this would show that it is not in fact an error in the reading/faulty sensor. Overvoltage and increased heat go hand in hand.

I think you honestly need to be more worried about the 1.52 24/7 than the spikes.

Bring it doen to 4.8 at 1.3 and be glad that you can still have a chip in a year.

Unless you are benchamrking the 200mhz will show almost no difference.

Ok Ok thanks for the help everyone. I think for the time being il just run at a slower speed and voltage. I might try turning all the power features and hyperthreading off just to see if it overclocks higher on less but more stable volts. Was kinda hoping to to keep all the power saving stuff on though and just scale with turbo boost. Let me have a little play and il report back here ina bit.

Have you tried reading the Vcore voltage directly off the motherboard to test? If it ever gives 1.9v your chip will not last past 6 months. Also even for 3 seconds that would raise the temperature by a good 10C. So check it manually and let us know what you get.
