The server would randomly lock up. Between just a few minutes from boot to 12 hours before lock up. I can still access the IPMI and remote console in. It displays the last screen before it stalls. There are no BSOD or Purple screen crash errors.
Things I've tried:
- removing all drives except for the ESXi boot drive (SanDisk Cruzer Fit 16GB USB)
- ran memtest86+ for 8 hours with no errors.
- swap RAM sticks
- disable Intel C States
- disable Intel SpeedStep
- disabled both C States and SpeedStep
- Flashed BIOS and BMC
- Load default UEFI settings
I get a lot of these errors in the logs:
"System Reconfigured,OEM System Boot Event,Undetermined System Hardware Failure,Entry Added to Auxiliary Log,PEF Action - Asserted"
The time on the motherboard loses the correct time.
#1 - Please, when seeking help, enter the make and model of ALL parts that your system is comprised of in your Signature, or at least the model #'s in your System Specs, then "Save' it.
____If you are overclocking, underclocking, or undervolting any parts, informing us of this and their values would prove beneficial in helping you.

#3 - Please use the eXtreme Outer Vision Power Supply Calculator found HERE to determine if it might be your PSU at issue.
____Consider your PSU to be the foundation from which all else is built upon. Anything built upon a weak foundation is poorly built.
New build. I believe the lock up causes the time to become incorrect. Even with NTP enabled, it is wrong after I reboot after lockup. It does not reync to NTP correctly.
