Hi. We know that Ryzen 3xxx series has many problems on MSI boards until today. My problem is 100% related to nothing but RAM incompatibility, which means something is probably wrong with the bios and memory controller. On ryzen 2700x the same memorie sticks are working perfectly in dual channel. On Ryzen 3600 they work in slots 1 and 2 (counting from the CPU), but inserting RAM into another slots like 2 and 4 (for dual channel operation) causes 3 long beeps - that is, a problem with RAM. Please ask me, I will provide more information. I think I am not the first to have this problem and the new Ryzen have a big memory compability problem. It works fine in single channel - but performance is terrible.


I have MSI B450 A pro with newest bios (30/08/2019)
