I've two of these and I've just swapped them (and re-pasted the heat sinks).
The second one ran under load for awhile and now has frozen as well. Under a moderate load `wget -O /dev/null <large.bin>` @X00Mbits they are fine. Under a 1 min speed test of load ~200Mbits routed WireGuard they freeze. They fine with both those workloads @1000_800. Perhaps it's heat? Unfortunately I don't have any numbers on that ATM.
