    3970x is not hitting max boost speed of 4.5ghz

    I recently put together a machine with the following specs

    Asus rog Strix trx40
    amd 3970x
    G.skill F4-3600C17Q-64GTZR
    nvidia 1070ti
    dark rock pro tr4 cpu cooler with thermal grizzly
    evga 1000 watt gold

    For some reason I can't reach maximum single core boost speeds of 4.5ghz. I have updated the chipset, updated windows, updated the bios. I have set my ram xmp in the bios. I have put all the fans to 100% which include 5 case fans and 2 cpu fans. The best I can get is around 4.35.
    I wrote amd and they said my ram is NON-QVL RAM and maybe causing the issue. Would this particular ram cause any issues with my stated board? G.skill F4-3600C17Q-64GTZR 16g x4

    Temperature is a huge influence on max boost

    That said you could try increasing max boost by 200MHz on PBO...this might free up the headroom a bit

    These CPUs need good watercooling to free their potential....however good an air cooler might be it's going to struggle to provide maximum headroom to TR
