I actually have just finished testing 192Gb(4x48Gb) of DDR5 5200Mhz (Corsair CMK192GX5M4B5200C38(Ver 3.53.02 - Has to have SN Starting with above 2311 on the first 4 digits) but with a standard Ryzen 9 7950X and it worked surprisingly well. I didnt have an issue at all which i often do with 4x32Gb. This was in an Asus Proart X670E Creator Wifi motherboard and that memory is on the QVL. I have also found that the same memory will work in the X670-P Wifi so that is next to test.
