i5-4670k does not have overclock enabled at the configured speed.
Hi everyone, I've finally managed my first overclocking tryout and am facing some issues.
I adjusted the clock to 4.5GHz at 1.15V and everything looks stable, but the CPU isn't actually reaching 4.5GHz. Prime95 and AIDA64 only run it at 4.0GHz, and during startup it tops out around 4.2GHz. This is true for all four cores. Raising the multiplier above 4.2GHz doesn't increase performance—it caps at 4.2GHz or 4.0 on both Prime and AIDA.
Throughout the process I only changed the clock speed, switched voltage to manual and turned off Intel turbo boost. Did I overlook something?
Any suggestions would be greatly appreciated.

I thought similarly, though increasing it to 1.35V didn't alter its behavior. I'll attempt a turbo boost and review the guide. Appreciate the guidance.
return to the bios and raise your CPU multiplier gradually in small increments while keeping the voltage constant. continue this process until the system begins to crash, then reduce the increment by one step. this represents your maximum multiplier at stock voltage. after reaching that point, increase the multiplier again until the system crashes once more. next, adjust the voltage slightly at a time until stability is achieved. finally, proceed with the stress test, increasing adjustments incrementally.
I'm not entirely confident in my explanation, so I'll attempt again.
The system appears stable, but it doesn't reach the speed I requested. Regardless of the speed and voltage set in the UEFI, the processor will only operate at 4.2GHz, which is within its stable range. The temperatures are also fine, around 65-70 degrees when using Prime95.
