Overclocking locked CPUs is old hat for Skatterbencher, who fits another 8% CPU clock on AMD’s latest CPU.
AMD’s Ryzen “X3D” processors are created by very literally attaching a second piece of silicon that is almost entirely L3 cache memory to the top of a regular Ryzen processor die, just like the picture above implies. It is the central slab atop the wider CCD. This second chip, known as the “3D V-Cache”, is very sensitive to high heat and extra voltage, and that’s why AMD disables overclocking on its “X3D” processors.Normally the CGPLL provides all three PLLs to the right.You have more control over the second-generation X3D chips based on Ryzen 7000, but they’re still multiplier locked. So how do you overclock a CPU that is locked from overclocking? You use the base clock. This introduces all kinds of issues on platforms that aren’t intended for it, but thankfully, AMD designed Raphael with this idea in mind.
