Is PO3-620 motherboard limiting multicore performance because it can't adjust CPU voltage?

Not so much a question, just a report for anyone that is still using a PO3-620.

I upgraded my CPU to an i9-10850K with a Noctua NH-U9S with no overheating issues. The motherboard throttles the CPU with the voltage that can't be changed.

I also upgraded my system's RAM to 128 GB.


As you can see, it shows a slight improvement, but I am not getting the multicore performance I should. It's a good thing I got a deal on the processor.

And the memory. Four 32 GB modules. The recommended Crucial memory.

    The PO3-620 motherboard, designed for stock 10th-generation CPUs (like the i7-10700), likely has limited or no ability to manually adjust CPU voltage beyond the factory settings. When you upgrade to a higher-end, unlocked "K" series CPU like the i9-10850K, the motherboard's voltage control might not be able to provide the necessary power to run the CPU at its full potential, leading to throttling to prevent overheating or instability.

    While the Noctua NH-U9S is a good cooler, it might not be sufficient to cool the i9-10850K at its full potential, especially if the motherboard is throttling the CPU to a lower voltage. If you want to unlock the full potential of the i9-10850K, you'll likely need a motherboard that supports manual CPU voltage control and overclocking.

    Even if the motherboard has limited voltage control, you should check your BIOS/UEFI settings for any options related to CPU power limits or voltage settings. Some settings might be able to allow for a higher voltage, but this is not guaranteed.
