Created attachment 1981395 [details] r7a.medium_dmidecode_debug.bin Description of problem: During test R7a instances in 2227069, dmidecode shows Processor Upgrade: <OUT OF SPEC>. Below is details: From the dumped bin file, it seems that aws provides value in this field, so I guess it is because '4a' is new defined in smbios spec 3.7(Socket SP5). Please double check. I guess the tool needs update accordingly. 00000100 45 43 32 00 00 04 2a 04 00 01 03 6b 02 11 0f a1 |EC2...*....k....| 00000110 00 ff fb 8b 17 03 89 64 00 74 0e 28 0a 41 4a 05 |.......d.t.(.AJ.| $ dmidecode --from-dump r7a.medium_dmidecode_debug.bin -t 4 # dmidecode 3.4 Reading SMBIOS/DMI data from file r7a.medium_dmidecode_debug.bin.
