-28 all core seems impossible, Ryzon Master says -25 is ok but as soon as it’s loaded it crashed. I ended up trying 25,20,15,10, 8 and 5. -10 was very close but now I just don’t bother with it as I use ECO, I can do a -8 which bumps performance up a bit but not enough to be worth it. My chip must suck, CCX 0 sp = 121-123, CCX 1 sp = 112-116, Average sp = 116. Do the 3D chips have 2 high sp CCX’s?Yes.
