Overall Review: I have seen some reviews going around dogging this because of ram issues. Its not the motherboards fault. I did tons of research & cross reference that certain ram will only work with certain CPUs in the QVL. So for my gf to run (CMP96GX5M2B6600C32W) 96GB of dominator ram from Corsair she had to get a Ryzen 7 9700 or 9800xrd or Ryzen 9 and above. The other am5 would not work. The other review on here cant speak to it not being compatible, but i believe that is the issue they ran into was compatibility & not the actual motherboard having the issue! So far this thing has given so many improvements from her old motherboard she had & no issues or complications! She can now handle her games and stream with this motherboard and paired with her 9700x perfectly without any issues! I would recommend!
