I've tried the machines with two types of power sources (different UPSes, line filtering, etc, and the chassis have redundant PSes), monitoring the temperatures (seems to be OK, the CPUs don't go over 30 °C even under load). I have the latest BIOS for the motherboard. But I will recheck everything. BTW, here's the output from mcelog, I see this occasionally on all four machines: HARDWARE ERROR HARDWARE ERROR.
