    I think it's a record (gpu score).

    edit: Scratch that, there are higher gpu scores (not by much...)

    This is OC im using now for Playing games.
    Rage 2 VLK = OK
    BFV MP = OK
    HoMM VII = OK
    Vampyr = OK

    3Dmark up to 1175MHz (bench-stable only)
    3Dmark 1150Mhz = OK
    Gaming OC is ~1120MHz @ 912mV

    I am sitting at 88c on Junction. I am under water though.

    Haha good catch, I will.

    Oddly enough I have a second Radeon VII still sitting in an unopened box on the floor.

    great program.

    using this I don't need OverdriveNTool right? cos as I see it, mem tweak has the some stuff + more for mem.

    mem tweaker is not the same as using powerplay tables right, in case I decide not tu flash vega 64 bios which I'm less and less inclined to do after reading all the bad stuff that come from it?
    I didn't get the time to readup on powerplay tables yet.

    I really like the GPUTool from TechPowerUp, it shows VRAM errors as yellow points and shows "XX Seconds since last error" in the bottom left Corner. Just click "Test for Stability" and that's it.

    Oh yeah btw, seems my Vega64 is done for at 1115Mhz... 1120 barely works, but 1125Mhz shows errors every 40-80 seconds.


    After a lot of testing i got these values stable:

    BTW, changing the "Timing Level" Dropdown does not change anything.... that's a bug right?

    If you use Ntool to change the Timing level you can see it changes tRRD* values and maybe some other values that are not exposed. Memory tweak doesn't show the change when you toggle it because the value is already being set manually I think that is by design and not a bug.

    tCL at 14 is usually slower because it probably defaults to 18. Optimal value seems to be 16.

    That software doesn't work for me (rx 480), it doesnt show any clocks (all 0 or --) and it won't even let me change them

    Hi,

    I can’t modify timings on my RX 580 4gb. Some of them are blurred. Why is that?

    Is there a guide or something?

    AMD's timing levels do almost nothing on Vega. According to your tool anyway. And benchmarks done by various others(you've probably seen what I'm referring to).

    I just now decided to fiddle around with the timings on my Vega 64. Figured I'd start by checking what those "Timing Levels" were doing. Pretty much NOT A DAMN THING.

    The only timing that changed was tRRDL(Row Active to Row Active Delay Long).

    Timing Level 0: tRRDL = 6
    Timing Level 1: tRRDL = 5
    Timing Level 2: tRRDL = 4

    All other timings stayed EXACTLY THE SAME. What a JOKE!!!

    Anyway...thanks for the tool. :)

    THX Bratan :D :p:cool::)

    Make it without Testing Mode (Win)
    Some games (UBI for example) do not run with it.

    Is Fury/HBM1 still unsupported? I'm just getting a blank application (I'm on driver version 19.7.3)

    I could, but then i'd need a certificate, which isn't cheap to start with.
    Not "that" easy to aquire.. otherwise, gladly!


    I did a quick test on a Fiji nano here, ran fine.
    But there's no powerplay/strap support for fiji so you could simply use Amd Memory Tweak (non XL).
    It uses IOmap driver which is already signed and therefor also don't need test mode.


    Cheers

    Oh right, didn't realise you brought support up in a prior release, can confirm it's working :)

    Time to read up on improving memory timings then!

    Thanks for this :D

    Thanks for the update. Is the test mode so that the program can write to the registry for the powerplay tables? Wouldn't it also work by just exporting that data to a reg file like VegasoftPowerTable editor does and then the user could install it manually.

    Is there anyway to make the timings set on boot. I tried to make shortcut to set timings but could never get it to work.
