    Well i went for two separated cable each 6+2 pins.
    Going to test a single one with 2x 6+2.
    Wish me luck :D:D

    EDIT: Still no changes at all...

    EDIT_2: Went back to 264 Watt, UV like on the post earlier leads to instant crash when i start a Benchmark test on TotalWar: Warhammer 2 settings a mix between High/Ultra.
    Default settings, started GPU-Z and Wattman and look at the Clock ->

    EDIT_3: I did a downclock from 1702Mhz to 1602Mhz, now the card reaches a max 1533Mhz.

    Is it just me or is the new driver 18.10.2 stable?

    Yup, 1820Mhz will carsh on any Vega not only yours.
    Please make sure is stays up to 1732MHz to 1750 Top !!!!
    OMG, bro it will always crash.

    And if you change BIOS to 220tW one then it will crash when you reach 1650-1700MHz ;)
    Max clock observed on my 3Dmark was 1757MHz ! and it gives me >28k points.

    Do not use 1.25v !!! Max 1.100v-1.125 Power slider to 0% or +1% or -5% depends on gameing scenario.
    Vega can be Very energy efficient and also an Power Hog ;) depends on Your settings.

    It was stock settings without any changes, apparently the card spiked so high on clock that causes the GPU to crash.
    Need to check how much clock i can go for without any spikes that leads to a crash.
    Also need to check some UV settings to see if i get the card stable.
    UV on P6 and P7 should be enough?

    When i use a Regfile it changes my Watt status from 264 to 220.

    It shouldn't do this.
    I have Tweaked PP & have 264tW ;)

    Thanks alot, you and of course the others helped me alot :D

    The GPU seems to be stable now with UV settings without any problems :)

    Great, finally -> Now go and Play some Games.

    PS.
    For the time being, check in HWinfo64 some gameplays (1h, 30min to see if everything is in check)
    Do not cross 1732MHz line (it's not needed for gaming)
    I have 2 Profiles for more demanding Games
    1. 1717Mhz/1150HBM
    2. 1732MHz/1175HBM
    But most of the time i have 1700MHz (Bf1) or 1650MHz (this for Forza)

    For UE4 games im using less HBM OC up to 1135MHz

    Yeah went down on like 1700Mhz but apparently my GPU is unstable on low frequenzy somehow.

    Its almost between 500-1200Mhz and its not holding the FPS constant. huge drops and leads to stutttering.
    For example, when it gets to a huge intense GPU usage the Clock drops and also the watt goes down from ~260Watt to almost ~110Watt.

    Even my R9 390 could hold the FPS without any problems.

    Does AMD have a option for power management per game profile?
    By nvidia it's; adaptive, optimal, prefer maximum performance.

    Prefer maximum perfromance always fixes such fluctuations and keeps it pinned, e.g. in my case 1405, otherwise it would go anywhere from 1000-1405mhz, even bellow bios 3d state p0 1278mhz > boost 1405mhz.

    Go into BIOS and disable NX Mode
    It should be OK.
    Now my only advise is to Set again Properly BIOS.

    It's Win 10 fault, 80% sure of it.
    All need to be set Fine, and if one don't know OS settings on Advanced level -> then we have a problem ;)

    It was activated and i had no settings changed on my BIOS.
    Since i do not have much knowledge about it i did not change a thing.

    Looks like im one of that kind :oops:.

    Vega needs 45A single rail from PSU -> Try to put cables properly
    (Use only 264W BIOS)
    Gain knowledge bratan' (Bro) :D
    Solving problems is not so hard.

    I did like you said, now im using a single cable from PSU to GPU.
    Doing my best here :p.
    Sometimes it tooks time to solve them and i think i found the cause of the problem.

    Seems like my R5 1600x is slowing down my GPU. Did a OC yesterday to 3.9Ghz and im not having FPS drops anymore. Guess stock CPU is bottlenecking my GPU ?

    Yes, The OC on CPU can make a difference with higher steady FPS.
    I was saying I assumed you had the CPU OCed.
