You recently purchased a 14900KF and checked out a guide on undervolting without hurting performance. The guide mentioned a different BIOS setup—specifically CPU CORE-CACHE VOLTAGE—while your system uses VRM CORE VOLTAGE and GLOBAL CORE SVID VOLTAGE. Decide which one to use based on your adapter’s recommendations, as the -0.050 adjustment is likely tailored for that configuration. Thanks!
Hey there, what board are you using? It helps us understand the available options better. When I adjusted the voltage on my 13600k with an MSI board, it was straightforward—just set core voltages, tweak P and E multipliers, choose 'CPU Core Voltage Mode' to manual, and adjust until stability returned. I also experimented with a setting called Lite Load Control, though I’m not sure what it did. You might want to explore the LLC (Load Line) settings too. People have different preferences for voltage modes—adaptive, offset, or manual work best depending on your needs. I prefer manual because it lets me lock in values and see how external factors affect performance. At this stage, don’t change VRM or cache voltages; just stick with what you set.
I own an Asus Z790 Apex and I’m not very familiar with overclocking. However, I’m sure the 14900k receives more voltage than necessary for stability, but it should handle an adaptive offset of 0.05 without any issues. The differences in the menus make it hard to tell which one is which.
From what I can observe in the attached images, I recommend keeping Global Core SVID Voltage on Auto, adjusting the CPU Core and Cache Voltage manually, and proceeding accordingly. Are your power and energy cores locked? What are your goals?
Traditionally, an all-core OC aimed for the highest turbo frequency on one core, but that’s hard to achieve now. Based on what I know about the 14900k, I’d recommend assigning your P-cores to x55 and E-cores to x45. My 13600k sits at x54 and x44, so the 14900k might handle a bit more. Adjust the Vcore in manual mode to 1.3v (possibly still a bit high) and check if the system boots fine, runs Cinebench R23 several times, and doesn’t overheat. In BIOS, consider removing any AVX offset or setting it to zero—some chips default with a negative value.
It seems the default configurations for the 13th and 14th generation Intel processors are quite high. I was surprised when my first boot showed such elevated temperatures, even with custom loop water cooling. Be sure to run a few Cinebench R23 tests after each adjustment to check temperatures and stability. Start with small -0.1v changes and gradually increase to +0.05 once you notice any instability.
You're unsure about which option to select since there are many choices available.
