Thank you for your help. Sadly the bios reset didn't helped. It's also the newest version. So it's a defect or the ram is not compatible. I think I'm gonna refund the MB & RAM.

Yea, I'm just using CPU1 slot atm and I tried it on the CPU1 RAM slots.

Hi, I'm here for some advice for my new supermicro board. At boot process I get an error got and then it's stuck. On the screen it says "PEI-CPU Initialization" and in the right corner is a "B7". I googled the code and found out that this is memory related. I've tried two different memory sets. One 64GB set from Samsung (4x16GB) and one from SK Hynix (4x8GB), both with the same error code. The motherboard is an Supermicro X11DPL-I for socket 3647. The manual says max. 8 GB for RDIMM but it doesn't work. I also tried different combinations and just a single DIMM on the mainbaord in different slots. Could the be a CPU or motherboard error. Or is it RAM related, because it's not on the supported list from supermicro?
