Hello there!

I have a i5 4670k running at 4.2GHz with a voltage of 1.215v on a ASRock Z87 Killer.
The thing Is that I like the power saving features of the i5 (the cool 800Mhz at 0.7v), but when I run Intel burn Test I can see the voltage spiking to 1.301v, that's seems to be the only time that happens.

Should I be worried? Is it best just leave it at Override at a constant 1,215v?
Or is it best to have it cool most of the downtime and let it spike 1.301v?

My GPU is a GTX 570 so I don't know I should even OC the CPU at this moment, the only games that really seem to push the CPU are Battlefield 4 and Wildstar (and the last one in going the way of the recycle bin, so very poorly optimized).

Thank you for the help in advance!

You do not want to have dynamic voltage when stress testing. Motherboards raise the voltage way to high when you stress test. Set it at a static 1.225 or 1.215 and test then. You should be alright! :)

I set my Vcore to fixed voltage ("Override") during stress testing and dynamic ("Adaptive") during normal operation. I like having my CPU idle down during periods of low load, which is frequently the norm for my system.

With my voltage on Override it seems to be able to hold on at 1.215v, even with Intel burn Test.
So it's no problem if I set it to Adaptive and let it sometimes hit a spike of 1.3v?
From my Hardware Monitor readings I had, today, a voltage spike of 1.305v and 70c.
It is ok or it would be safer to have if locked at 1.215v?

Thank you for all the answers so far.

That is high. For normal use, 1.2 Volts at 4.0 GHz or less is good.

I wouldn't be concerned with spikes to 1.3 v. Core temp of 70*C. is also fine.
