Hello, recently I bought Ryzen 9 5950x for my workstation that has 4 sticks of ram - 48gb (2x8+2x16) HyperX 3200mhz with xmp1 enabled, on MSI Tomahawk Max B450. Sometimes under load I had sudden black screen and CPU debug led. I knew that 5950x is too much for b450 and I thought that was the problem. I bought Aorus Pro x570s ax and now my pc won't post when xmp profile 1 (3200mhz) is enabled, I got black screen and DRAM debug led. Sometimes it boots normally and but very rarely. When I disable the xmp profile and the memory is working on 2400mhz I don't have that kind of problem. I tried updating bios and all drivers, tried to turn on the pc with only one or two stick of ram but that does not change anything. Any ideas what could it be, or how to solve this problem ?
Otherwise the pc is very stable under heavy loads.
Thanks in advance.

Could it be that your motherboard dose not like the timings of your ram or could it be that XMP profile trying to clock the ram higher then should and . Could you try manually putting the 3200mhz without using XMP or try 3000mhz that still good speed!
