    Hi mate.
    I´m having the exact same error.
    The problem it seams to be only in this new Amd driver 21.12.1.
    Does anyone know how to fix this?

    I have the same issue using modded 21.12.1
    Wasn't sure if it was 21.12.1 or the modded drivers, probably something under the hood in 21.12.1. I'd like to find a way to tweak memory timings with new drivers because I can already reach higher stable memory overclocks using SAM/Resize BAR on my Vega 64.
    At a glance it seems like the hardware flag isn't being picked up as being supported so it might not be a big problem to correct.

    That looks like it does on my Vega 64, good score.

    Here's my current timings, as well as a hint at how I arrived at some numbers. Works very well with SAM

    Here are my timings I use with HBCC @16 gigs enabled.

    My timings are tighter than ever, but I had to lower my memory clock to be stable @ 16 gigabytes

    Step 1: Apply undervolt in drivers
    Step 2: Apply memory timings

    I can probably bring RFC timing down a bit (220 or 240) but I want to make sure this is 100% stable before tightening that.

    Try tREF at 24k or 26k -> AFAIK is good for gaming this way.

    Hi i cant get amdmemtweak to open i tried all beta versions in the github repo. There was a note in beta2 that says if you cant get it to start try this link: http://eliovp.com/x64GUIVersion.zip but the link is dead now.
    I am using driver version 22.4.1. Does anyone know what is the latest driver that works?

    Does anyone have the version in the dead link so i can try it? If not does anyone have any suggestions on what else can try?

    Thank you OnnA for taking the time to help me but unfortunately i get the same error with this version too.
    I uploaded a screenshot of my error for reference.

    I am reluctant to use older drivers because i also game on this pc so i try to stay as up to date as i can for the sake of stability while gaming. That said if the only way to get AMD Memory Tweak to work is to use an older driver then what is the latest version that is known to work? I will give that a try.

    It seems it's not working anymore with new drivers.
    Try some old driver to acknowledge this :cool:
