    thanks OnnA.
    but is it restored/disabled when I close the program or I need to do that later/somewhere?

    It's not recomended (by me) to have it always On.
    Best is for You to set PP_table (as You like) then import it by OverdriveN Tool ;)
    Then use regular Mem-Tweak version for Timings Mod.

    On (paste this into Comm.prompt)
    bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
    bcdedit -set TESTSIGNING ON

    To turn it off again, use these commands:

    bcdedit -set loadoptions ENABLE_INTEGRITY_CHECKS
    bcdedit -set TESTSIGNING OFF

    how exacly do you import these tables with overdriveNtool :confused:?
    didn't know you can do that. I never use overdriveNtool, only amd tweak memory 0.2.3.
    thanks

    Hey, be careful with the amdmemorytweak xl tool. I've tried overclocking the memory by increasing mvdd to 1390 (specified max safe for gddr6) from 1350 and it messed up my vram on 5700 XT Red Devil.

    None of my previous minor memory overclocks work anymore, it starts to flicker to black in <10s intervals, more frequently if you don't close the load, until it 'black screens'. Doesn't lose the signal, doesn't freeze. This also happens on idle, desktop, just doesn't permanently crash. Playing with soc voltage doesn't help.

    So far 1750 mhz (stock) seems to be okay, but even +10 mhz, 1760, 1770, 1780, 1790, 1800 mhz don't work anymore.

    https://i.imgur.com/YEZvp9G.png
    Here is the comparison between max core oc with stock and with max memory oc 1830 mhz (1.39v) on Timespy. You'll be getting like 1-2% tops (1 frame), that might not even stick after a restart. And you have a high chance of messing something up. Don't bother. Some scenarios might have a bigger impact on memory oc, especially when the framerate is above 120 or something, but that's still relative %.

    Too bad I can't even set my memory to 1780 mhz, which would increase the score by almost 100 pts. Auto memory oc through AMD drivers sets it to 1840/1830 that have never been stable in the first place, only with the voltage mod.

    I've tried reinstalling drivers, so its permanent. I've used it for like an hour or two of light gaming. Temps were good (80c on vram, 65c core).
    Another user on reddit claims that his 5700 XT has died a week or two later by only running a couple of benches on 1390 mv (+40mv).
    I've created this account only to post this, so hopefully someone saves his card and sees it in time. (Navi 5700/XT users avoid oc'ing vram this way!!)

    Note: My default vram graphic scores were closer to 9700. So I don't know what it did, but the default score of 9800 seems abnormal, too, maybe I'm just paranoid. Someone can test it if they'd like @ 2104 core +50% power, 1175mv or higher for testing purposes. Timespy 2560x1440. (The highest I could get. 9845. https://i.imgur.com/LZ1iZlD.png ) Maybe this tool has changed something permanently, I'm not sure. I've tried resetting everything. Anyway, leave the mvdd stock : )

    Also, I don't know if the maker of this tool is going to read it, but there is a 50% chance of blackscreen when running the tool itself. I guess it crashes the drivers. Sometimes I need to restart windows 5 times to open it up. Windows 10 x64. Adrenalin 2020 Edition 20.2.1 Optional 2/3/2020.

    @Soeris ,

    The tool simply creates a registry file based on your values.
    Remove registry entry and your problem is solved ;-)

    Cheers!

    ~7% performance uplift
    Mine is 56 Hynix
    Have you flashed yours?

    I tried you timmings and windows exploded xD

    I'm using a some undervolt settings which works better than turbo settings and consume less power

    Attached are my drivers settings, but I dont know much of working with the timmings.

    And no, I'm using stock bios no flashing here.

    Hey Onna, what are you running for your PPtable voltages and frequencies, or are you just using the same values that are listed in this photo?

    Im always Playing Games with this Mem tweak.
    It's fully stable up to 1175Mhz HBM2... Try to set what's best for Your GPU.

    yes you have to ajust whats better and depends on game also.

    I can run all day 1200mhz on hbm but on ark I can only run 1100mhz.

    So it really depends.

    Hello everyone. I have a Sapphire 580 8GB video card. I wanted to write the REF 30 parameter to the BIOS. What address is it, and how to do it? Thank you.
