Customer reported Memory error (memory mapped out) during boot up. The Server is SYS-4029GP-TRT. Memory DIMM in questioned are: 64GB MTA36ASF8G72PZ-2G9E2 from Micro and 64GB from SamSung. But 32 GB memory from SamSung has no issue.
Customer's Server is with Xeon 6142 (Skylake CPU). Customer's 64 GB memories from Micron and SamSung are all with 16Gb chip. Skylake CPU can't support 16Gb memory chip memory DIMM. Customer's 32 GB memory is not with 16 Gb, so it works fine. Please go to product website and check the supported memory.
