    When load hit the cpu, you want the LLC to act fast, or the cpu wont get enough thrust to handle the load, in terms of vcore = vcore drop = instability = crash eventually

    4800mhz 24/7 offset

    Idle>

    4800mhz at 1,38v, i think its normal..

    do you have custom loop?

    yes i do..



    Check for the vcore drop under load, if it drop 2 much = instability.. compensate

    its about providing the right amount of thrust, at the right place, at the right time, and that goes for all the voltages (more or less)

    Thats the tips i can give you..

    It got complicated again i feel..

    Example >>> 4800mhz in offset

    Example> if my OC profile was made so the VCORE peak was about 1,35v at 4800mhz max load, the system wouldn't be stable, or my phase control setting was too slow = crash is just a matter of time, if the load gets very hard, or for a long period of time.. 1,35v would be enough for a short load peak, but not cut it for 24/7 usage.

    Because i know my cpu need 1,370v-1,380v to pull of a stable 4800mhz clock.. and thats the goal for my offset voltage (1,38v full load), so i check cpu-z for the VCORE when i stress the cpu, how fast it respond, and how high it goes, and the voltage duration / max cpu load, and possible voltage drops..
    the VCORE duration at max cpu load is important, to ensure stability..

    The ROG boards Phase control can be used as a great tool, to reach the wanted voltage, in more ways than one..

    The VCCIO is easy, just keep it 0,3v (delta) below the actual VCORE voltage peak (which in my case is just 1,375v-1,380v) so my VCCIO is set at 1,075v-1,083v

    many variations doing this, and many ways...

    So by running Prime95 for hour after hour is totally pointless, its about fine tuning (what your cpu specimen require), not brute force,.. multitasking, combinations, different calculations, and so on, thats what show the real stability in the end.. not just running one task.. because you got more HW than just the cpu, that can cause instability..

    if you got a stable 4800mhz already, please ignore this..

    And enjoy instead..

    Good temps..........

    Mate that is one of the better CPUs I have seen. You just enjoy it. Do not kill it by stress testing the **** out of it please.
    To help us help you - please provide as much information about your system and the problem as possible.
