NUC 13: Random Freeze (alien.top)

Hi there,

I set up a new NUC13L3Kv7 a few days ago and installed VMware ESXi on it (to serve as a vSAN Witness).

Unfortunately the NUC keeps randomly freezing from time to time. This mainly happens after being completely idle for hours.

Not even the vPro/AMT webpanel is reachable if this happens (maybe it’s just the NIC that stops working after some time?).

I’ve tried multiple different BIOS settings, updated the BIOS to the latest version, etc. but nothing helps.

Any ideas?

Number one cause of random hard crashes/hangs is RAM. Re-seat it, replace it, down-clock it, run a single stick, do everything you can to either rule it out as a problem, or to isolate the problem to a particular module or channel.

Memtest86 didn't find any problems, but I'll try out some different RAM configurations. Got some spare DIMMs flying around..
