Yes, 1.5V core VID spikes can occur on the i9-10900F and are not necessarily a problem.

The spikes appear only when the CPU reaches 5.2ghz, which happens just during program launches. Under heavy load like Cinebench it stays steady at 4.6ghz and occasionally jumps to 4.7ghz. Can I achieve a 5.2ghz boost in games? Your HWInfo screenshot shows peak power usage and temps from Cinebench results. The max core voltage is around 1.25V during load, with stable 1.25V core VID while launching programs. BIOS settings: ASUS Multicore Enhancement – all limits off; SVID behavior – typical scenario; CPU Core Ratio set to Auto. VRM calibration level 5; internal power limits at 255.75; LP1 & LP2 timed at 4095.
Core turbo runs at 4.6GHz and doesn't allow overclocking to 5.2GHz in games. You might achieve a slight boost by adjusting BCLK, though the gain would likely be only 2-3%. VID reflects the CPU's desired voltage, not the actual supply. The highest stable reading here is Vcore at 1.314V, which is reasonably safe even if it isn't the most precise measurement.
I would apply load line 4, configure the voltage in offset mode with a negative value, not positive. This processor doesn’t require additional voltage and functions well with lower levels. It will cut power use and heat generation. For instance, a -75 mV undervolt keeps temperatures manageable. Begin at -50 mV and verify stability. You can’t overclock a locked CPU, so it won’t need much voltage. A comparable 10-core chip runs at 4600 MHz and only needs about 1.163V during Cinebench R20, which helps maintain a package temperature of around 59°C.
