Can you increase the speed of your 4460 despite it being locked?
The title clarifies that non-k model processors lack overclocking capabilities, yet certain skilled users manage to do so.
You have options, but they differ from what you imagine. Increasing a CPU's performance can be achieved in two ways: by boosting the multiplier or (and) raising the BCLK speed. Non-K chips typically have a fixed multiplier, so the only viable method is adjusting the BCLK, which starts at 100Hz by default. For instance, if your processor operates at 3.2GHz, the multiplier is set to 32 (32x100MHz equals 3.2GHz). You can only increase the BCLK up to around 105, which would push the speed to about 3.36GHz. Such a high BCLK also impacts memory and PCIe bus performance. I've managed to reach 103MHz on my board through experimentation, and it functioned properly. The higher cost of K-series chips is understandable, as they require more advanced Z-series components.

I’ve managed to reach 103MHz on my board through trial, and it worked. The higher cost of K-series chips reflects this, as does the need for a pricier Z-series motherboard rather than an affordable H-series alternative.
you can boost performance by raising the BCLK, but it's different from earlier systems where the PCie clock was independent. If you go up to 1Mhz, the CPU may overclock briefly, but the PCie clock will also increase, and pushing it too high could harm your motherboard or GPU. I believe 102-103MHz is a safe range, though I wouldn't risk it for a full 100MHz overclock on the CPU.
