Issues upgrading R720 CPU from E5-2690 v1 to E5-2987W v2

Hello,

I have two R720 hosts, and when I took the first host offline and installed the CPUs, it didn't go well. When I try to boot with both new CPUs it triggers two types of errors. The first is each CPU triggers "VCORE PG VOLTAGE OUT OF RANGE" or something like that (I can get specifics if required), and the second is "MOTHERBOARD FAIL-SAFE VOLTAGE OUT OF RANGE". I confirmed by BIOS is up to date at version 2.9.0.

I should also note, my method of upgrading was just taking out the old CPUs and putting in the new, I am not sure if more needs to be done to complete the migration between verisons.

I have two, 750 W power supplies, but have not checked my motherboard revision as I am not sure how to. Please let me know what other information I can provide.

Thanks,

Sean
