I let it sit over night to "cool down". Upon boot-up the CPU temperatures started around 104-105 F. Letting them sit in the BIOS noticing the temperature go up over 130F. Booting into 5.2.1 with SMP kernel, I ran my perl fork mysql test scripts six times then it froze. Back into BIOS I went again after a power cycle and the temperatures were at 185 and 175. Not as hot as yesterday, but I only had it up for 10 minutes total from a cold state. Anybody have any temperature monitoring apps for amd 5.2.1? Anybody know what the lock-up temperature is AMD sets into their chips? Or does anybody know how hot their 1U dual opteron 246 servers run? :) -c
