Thermal Grease on Processor
Recently, I was dispatched to a data center for a system board and CPU replacement. Upon arrival, I found that the server would not turn on. After unracking the server, I inspected the CPU pins and noticed that the socket pins were bent, with traces of thermal grease present on both CPU slots.
I promptly informed the end client about my findings and documented the situation. I was instructed to proceed with replacing the motherboard due to the damage to both CPU sockets.
Memory diagnostics show the following results.
* All DIMMs associated with CPU0 were detected successfully.
* On CPU1 only four out of eight dims were detected.
* All DIMMs associated with CPU1 consistently failed validation.
Further troubleshooting was performed by swapping known-good DIMMs from CPU0 with the non-detected DIMMs on CPU1. Results were consistent across multiple tests.
* DIMMs previously reported as failed on CPU one functioned normally when install installed on CPU0.
* Known-good DIMMs from CPU0 reported as failed when installed in the affected CPU1 DIMMs slots.
This behavior confirm that the DIMMs themselves are functional and the system is isolated to the CPU1 memory channel or associated DIMM slots on the SYSTEM board.
When is this going to stop? Pizza Pete? Don’t take the jobs you are not qualified for.
