Right now i'm taking a more careful approach to overclocking (I don't intend to push it too hard soon), so I activated the XMP profile but adjusted the offset voltage to -0.140 to slightly undervolt the CPU at 4.6 GHz. My LLC is set to level 4. When running a prime95 test and checking voltages with CPU-Z, the CPU voltage comes out around 1.34 volts. Does this suggest the XMP profile is ignoring my previous setting and not using the -0.140 offset?

What temperature are you at? At this stage, I believe raising the CPU voltage won't help much. Restore the voltage offset back to standard levels. XMP settings apply to your memory, not the CPU. The component handling memory speed is the IMC built into the CPU.

What cooler are you using? At this stage I believe adjusting the CPU voltage won’t help much. Restore the voltage offset back to standard levels. XMP settings apply to memory, not the CPU. The component that controls memory frequency is the IMC built into the CPU.

I’m running an Enermax Liqmax II 120s. How can I fine-tune the voltage for stable temperatures? I’ve experimented with adaptive voltages, but it seems they don’t let me change the Turbo Mode offset beyond a minimum of 0.250. I want to set it to 0.150 using the offset, but when I type 0.1 and press enter it automatically switches to "auto". I’m considering a manual voltage of around 1.28, but I don’t want the CPU constantly at that level.

I've understood that the offset voltage functions properly. Without it, the vcore would hit 1.44 volts during Prime95 tests—which is quite high in my view. With an offset of -0.140, it only reaches 1.3 to 1.35 volts under Prime95, and it appears stable even when idle (I haven't seen any crashes or BSODs with this setup).
