What is it? And what causes it?
Is it only for uncorrectable DIMM Errors(Troubleshooting DIMM errors)?
When an UCE occurs, the memory controller causes an immediate reboot of the system.
During reboot, the BIOS checks the Machine Check registers and determines that the previous reboot was due to an UCE, then reports this in POST after the memtest stage:
A Hypertransport Sync Flood occurred on last boot
3 BIOS reports this event in the service processor’s system event log (SEL) as shown in the sample IPMItool output
There are what seems to be some suggested answers to include
- Bad Caps
- Bios verisons (happens in one version not the other)
- Graphics card issues
- Lack of power to the CPU
The list of possible generators seems to target everything but the computer case.
