i5-3570k clocked at 4.2 GHz and operates at 1.045 V
My specifications are:
CPU: i5-3570k
Motherboard: ASRock Z77 Extreme 4
Heatsink: Hyper 212 Evo
Paste: Arctic Silver 5
I am just starting out with overclocking. I installed my CPU cooler properly. I distributed the thermal paste uniformly across the CPU's surface, but because I used a credit card without prior experience, some areas lacked paste. I'm curious if this is why there are small gaps. Could this be the reason for the +-5C difference?
I can easily adjust to 4.0 without altering the default Vcore. I haven't tried lowering the Vcore yet for 4.0 GHz to achieve lower temperatures.
I've been gradually reducing the Vcore to 1.045 in my motherboard (Fixed mode) with a CPU Ratio of 42 or 4.2 GHz, which has provided stable booting and no crashes so far. It's running at 40°C during idle as well. I'm using Prime95 to assess how well my chip performs.
However, I have one question: is my chip actually operating at 1.045 Vcore, or is it higher? I've noticed others overclocking at 4.2GHz with a Vcore around 1.12-1.2.

It depends on the ambient temperature.
Yes, an i5 3570k can have a Vcore of 1.2 (around 1.26V in my case) at 4.2 Ghz, but I’m using offset mode so the CPU can downclock during low loads or idle.
Prime95 is mainly for thermal testing.
For better stability, check AIDA64 with a 24-hour test.
Also, monitor Window Event Viewer for any WHEA errors to determine stability.
