R650 R6525 - VLT0304, Description: CPU 1 VRM voltage is outside of range. - The system board Pfault fail-safe voltage is outside of range.
This is resolved. Sharing Steps Taken.
Initial Issue on a PER6525 -
Server would not power on, but IDRAC still working with the following errors in Logs shown in Title.
Steps Taken:
Motherboard replaced. No Change.
Swapped CPU1 and CPU2. No change.
Booted with A1 and B1 Memory minimum configs -> Boots Fine
Server has 24 DIMM slots used. A1-A12 and B1-B12.
Removed all DIMMs on CPU 1 side which would be the A Dimms.
Inserted the rest of the DIMMs from B side to slots A1-A6 and B1-B6 -> Boots Fine
Tested the rest of the remaining DIMMs 4 at a time. If it fails, I set those DIMMS aside.
After trial and error, found Two Bad DIMMS.
Swapped the suspected Bad DIMMs into a Lab Server R650 and this server gave the same errors.
Note: DIMM errors were never logged in IDRAC.
