Prilann Posted November 19, 2020 Share Posted November 19, 2020 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? Quote Link to comment
StevenD Posted November 19, 2020 Share Posted November 19, 2020 are both sockets populated? If using only a single socket, are you using the right one? Also, if you are using both, you must have RAM spread across both. Quote Link to comment

StevenD Posted November 19, 2020 Share Posted November 19, 2020 (edited) That motherboard should support a single CPU in CPU1 and and a single DIMM in P1-DIMMA1. Is it possible the CPU is newer than the BIOS supports? I typically only buy RAM that is on the SM approved and tested list.

StevenD Posted November 19, 2020 Share Posted November 19, 2020 Also, have you reset BIOS to make sure nothing like memory speed was set directly? Quote Link to comment

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. Quote Link to comment
