I have acquired NUC 5i3RYH and Crucial dual channel matched DRAM kit (2x4GB CT51264BF160BJ). The memory is listed as supported on NUC page Intel® NUC Boards and Kits — System Memory.
My NUC refuses to boot with both modules installed (power LED blinks 3 times). I tried either of the modules separately in the bottom slot and either boots fine. I have BIOS version 0137. The memory issue troubleshooting page is not very helpful (Intel® NUC Boards and Kits — Troubleshooting Memory Issues), but based on my understanding the dual SODIMM configuration should work with my NUC.
Is there anything else that I can do to troubleshoot?
