    Question about clock fluctuating on Rtx 2080 Ti.


    I have a question.
    I am using Rtx 2080 Ti Waterforce and 9900K and Corsair 850RmX.
    ALL stock,no oc. Drivers up to date,Windows 10 1903v.
    Few days ago ,when i run Fire Strike GPU test 1 on loop, i saw a clock dip from 1980mhz to 1570mhz for 1ms.
    GPU LOAD not changed,it was 96%. Only gpu clock dip for a 1ms. I checked in logs,and during that gpu power drop to 58%.




    I cant reproduce this. Second. Yesterday i run TimeSpy looped gpu test 1. Clock during 40 minutes was 1920-1970mhz with random power usage. But one time it dropped to 1800mhz. Is this normal?

    Screens: 1920mhz:



    And that 1800mhz for 1ms:



    Of course its POWER LIMIT only in this test. So i guess its not faulty hardware somewhere? In games i dont had any once such drops in clock. It happened in 3dmark once only and i cant reproduce.

    I know but that power drops from 95% to 45% for 1ms its not hardware related?

    I mena when test is running is always 95-90% power usage, but sometimes it drops for ms1 to 45% or 58% which result in stutter etc. Is this hardware related or software?

    Both, the hardware runs dynamically, not static, and software rounds things off, You are looking for a issue that isn't there

    How much time do you have to have the Allan Deviation, physics involving this area explained, design of electronic components and how they evolved from tubes, etc..
