CPU error on startup
Hi, we upgraded R720 server with 192GB RAM each stick is 16GB and dual E5-2680
previously it had no errors and now on reboot/startup it shows these errors
CPU0704 CPU 1 machine check error detected. Power cycle system
Non-Recoverable. CPU Machine Chk: Processor sensor, transition to non-recoverable was asserted
we updated the Bios and all firmware on the server
we tested the RAM, did a stability test, it those not show any even tried another E5-2680 and still sometimes it gives these errors

Hi,
as I mentioned above we removed a processor and even tried replacing with an another one
I reviewed the logs and there are no warning or critical alerts
