I7 model without performance enhancement beyond standard settings
You're adjusting your overclock settings to match the Cinebench K score for the I7-4770K. The numbers you're using seem to be a rough estimate of what you expect based on your current and target frequencies. It's important to keep in mind that achieving the exact Cinebench K score at 822 points typically requires stable frequencies close to the target, which is why you're aiming for around 4030 MHz. Just make sure your cooling and power supply can handle the load before you start pushing it further.
You might consider increasing the base clock, but it's not advised. There could be other reasons you need an OC beyond just getting numbers right. These CPUs aren't designed for overclocking, and without proper adjustments on a non-K architecture, you shouldn't expect success. Doing so could harm your CPU or motherboard if temperatures, voltage, etc., become unstable.
Some problems exist with baseclock overclocking in Haswell processors on Z97 and Z87 chips. In short, the base clock isn't just about processor speed—it also affects memory, SATA, and PCIe connections (though not fully on PCIe). This can lead to instability and unexpected issues elsewhere in the system. For many generations before Skylake, multiplier overclocking is the best approach. Skylake changed that because its base clock was separated from the rest of the system. Unfortunately, for Haswell users, the base clock remains linked to other components.
This frequently leads to issues and disruptions in areas of the system that weren't meant to be affected. I'm going to reset the BIOS now!
If your BIOS doesn’t allow securing the clocks of other devices, you’ll likely end up boosting every other bus in the setup. As @Founders noted, this approach can lead to issues. In my previous attempt on Haswell with a 4670k and Z87 board, I couldn’t exceed the base clock by more than 4%, which was insufficient.
Consider using a K-series CPU and then applying OCR cautiously. If you need more control, aim for the best possible setup while staying within safe limits.
