  • P3, P5, P7 are all on one side of the CPU, so it’s likely the cooler pressure on the CPU IHS isn’t even for some reason.

    Some ideas:

    1. Use more paste and make sure the paste imprint is even.

    2. Double check to make sure you didn’t mix the LGA1200/1700 standoffs which are different lengths.

    3. Make sure the excessively large universal Arctic mounting frame isn’t catching on a VRM component.

    4. Make sure the contact frame tension is even across all four screws








  • I recommend using Process Lasso proper. It’s not hard to learn and much more powerful. CoreDirector looks like Process Lasso’s Efficiency mode/CPU set/CPU affinity rules repackaged into one on/off toggle for every listed app.

    You can do more interesting rules with Process Lasso like keeping non-interactive applications off of the highest-turbo P-cores or restricted to E-cores to improve idle power. My 60/60/60/60/57/57/57/57 13900K idles at 8-9W with MSI AB, Discord*, Steam, and other apps banished to E-cores and never allowed to turbo the P-cores.

    *Discord gets 57x P-cores 6 and 7 as a treat.











  • HWInfo is saying the same as CPU-Z. You’re looking at the XMP profile box which is what’s baked on the SPD, not what’s running.

    Your XMP boot is likely failing and ASRock bios booted it in the slowest possible configuration.

    Set these voltages manually up to the max in parenthesis

    VCCSA 1.3V (max 1.35V)
    VDD_CPU 1.35V (max 1.4V) - this should be CPU VDD2, verify in HWInfo
    VDD_IMC 1.35V (max 1.4V) - this should be VDDQ_TX, verify in HWInfo
    

    and then try booting 5200/5000/4800. You then want to test the IMC using y-cruncher stress test on the “VST” test after you successfully boot. You only need to run it for 10 minutes. If it fails, drop the clocks by 200.

    Alternatively if you can live with 96GB, 2x48GB is much more likely to work out of the box.
