    A massive thank you @1usmus for your hard work. I used the tool with my T-force 8Pack 3200CL14 Samsung B-die and it worked great with the settings provided at 3600Mhz CL14-15-15. I think i have squeezed as much performance out of this processor i can get now lol.

    I couldn't use it on my Corsair Vengeance PLX cause i don't know what Hynix memory types Corsair used on them.

    Thaiphoon Burner will tell you what type it is. I have Hynix AFR for example.

    Thank you for this great tool!

    I went from an Intel platform to an AMD Ryzen 2700X, but kept the quad memory kit.

    The memory didn't work at the advertised XMP-settings at all (16-16-16-36@2800MHz, 1.2V, no-QVL), but this tool saved my day!
    The modules now operate perfectly stable at 14-15-15-32@3066MHz with a voltage setting of 1.38V (higher speeds should be possible but timings would be a lot looser according to the tool).

    @1usmus : Did you change anything serious from v1.4 to v1.6.x? I see some values (TCKE for example) going from 1 to 8 again (got almost all your versions in my storage to compare since 1.x) in SAFE settings, Samsung B-die @ 3200MHz CL14, and some other values changing slightly.

    My current problem is I did a BIOS update and since then my system is unstable, regardless of what I choose (current @ SAFE w/ 3200MHz, 2 modules). I read my RAM's timings from XMP and TRFC is set to 560 in XMP, but SAFE profile lists it as 256 (regular, is set currently in my BIOS) or 252 (alt).
    I notice the unstable setting when playing games like Sniper Ghost Warrior 3 (quits straight to desktop without error message on desktop with APP HANG in error log) or other games, which quit suddenly and without errors, only in the log "APP HANG" is visible. Nothing is overclocked, settings SAFE like I said above and under ADVANCED I took the most stable settings for RAM (load line calibration and stuff).

    RAM is set to 1.36V currently with SAFE settings from 1.6.0.2. Do I need more juice on those or do I have to change other values? I already followed your block diagram as far as I could, but it made my system even more unstable so after hours of fiddling around I reset all the stuff and used the settings above.

    Any help is appreciated.

    I'm running 32gb of Hynix CJB (16gb x2). Using the safe preset, I get one memory error every hour or so in memtest86. Do you have any recommendations on which timing to move, and in which direction? I already bumped voltage to 1.4 with same result.

    Using the latest Tool 16.0.0.3, I got my F4-3200C14D-16GVK to 3800C16-16-16-16 as indicated in the tool, using the timings provided by the tool.
    Only 1.4v so far though, instead of the recommended 1.45v.
    Not fully loaded yet to test. Coming later. Old Memtest works.

    Sweet timings, 63.1ns latency so far. :)
    Thanks :)

    1.41V, go up in increments. ;)
