I can run 2 sticks in XMP or whatever settings I throw at it (inc Ryzen calc SAFE timings).
It doesn't like having all 4 sticks in all at once no matter what I do, unfortunately. That includes dropping speeds to 2133/auto, increasing voltage, increasing timings.
Are the QVL with mobo manufacturers directly communicated with memory makers? I mean if possible, anyone from corsair able to put a word in with Gigabyte X570 boards?
BTW, my friend with X570 Aorus Xtreme motherboard has the exact same problem with the exact same memory kit.
