    Settings for full DDR4 SPD (ASUS)


      Hi folks,


      I´ll found some usefull settings (THX to flusher1 from reddit)  for people, who uses a MB´s from Asus. I´ll test this settings with my friends on my rig and the rig of my friends. A, B350-A, B350 - Plus, X370 and the ROG Crosshair VI Hero, with diffrent DDR4 Boundel (32GB - 64GB / Dual Channel). Dosen´t matter wich RAM we tested, they run with those settings on full SPD.


      RAM we tested:


      - Corsair Vegeance LPX 3000 (4x8GB / On B350-A)

      - Corsair Vegeance LPX 3200 (4x8GB / On B350 Plus)

      - G. Skill  Trident Z RGB 3000 (4x8GB / On X370 Pro)

      - ADATA XPG Dazzle LED Series (4x16GB / On ROG Crossair VI Hero).


      Don´t use D.O.C.P and follow those settings. And be sure to use the latest Bios Version.


      ! Cave !


      Your rig and CPU got 15° +/- more Tempreture on full load, with this settings. Dosen´t matter on air or liquid cooling.
