I have a 4670k i5 CPU paired with a Coolermaster Hyper 212 EVO, using an MSI Z97-G45 Gaming motherboard. I began overclocking two days ago and achieved 4.4Ghz at 1.224V. I'm running Intel Burn Test on "very high" mode for ten attempts. The system runs stably with temperatures around mid-80°C, as shown by AIDA64 (55-60°C). All performance remains consistent under full load. After two days, nothing happened—no crashes, everything worked fine.

However, when I tried 4.5Ghz, I needed 1.280V for stability, and during the hottest core test (Intel Burn Test), I reached 96°C. AIDA64 reports a maximum of 80°C. Is this within normal limits?

This is my first overclocking attempt, so I'm checking the BIOS settings to see if adjusting ring clock or voltage could help. I'm unsure about other options and will need to look into guides if this is the issue.

Thanks in advance.

What you are explaining is typical. Most chips reach a limit where a large jump in voltage is needed to boost the clock speed by another 100mhz. Usually, this marks the close upper bound of OC achieved because of power or heat constraints.

In that situation, your CPU wasn't working well. I suggest lowering it to 4.4GHz for better stability.

Baralis explains that what you're seeing is typical. Most chips reach a limit where a big jump in voltage is needed to boost the clock speed by another 100mhz. Usually, this marks the close upper limit of OC achieved because of power or heat issues.
