  • High VRM temps when overclocking x299 Designare EX - any advice?

    Silicon Lottery
    My cooler is a Corsair H150i RGB Pro XT 360mm AIO.

    My overclock is per Silicon Lottery's binned spec:

    4.5GHz Clock
    1.125V Vcore
    -3 AVX Offset
    -5 AVX512 offset

    I'm using Enhanced Multi-Core and Energy Efficient Turbo so my system only revs up to 4.5 under load. Most of the time it's running slow, silent and cool.

    Even at load, the CPU runs cool with temps in the 70s and 80s. Maybe sometimes peaking at 90, but never staying there.

    But certain loads, like FFmpeg transcodes will send my VRM temps thru the roof, peak the fan and set off the alarm.

    I thought this motherboard had VRM temp problems under control. In fact, I posted a thread on Gigabyte's x299 forum a while back

    Any suggestions on how to get my VRM temps under control? If I remove the OC and go back to my default CPU BIOS settings, I can run FFmpeg without the temperature alarm. But this OC is not aggressive. It's stable, and the CPU is running cool and unthrottled. I'm concerned about the VRM alarm and don't want fry my board. What should I do?

    Any advice much appreciated, thanks!
