use more powerfull 'cpuburn-a53' to do pressure test. power meter shows that 'cpuburn-a53' consumes much more power than 'stress -c 4' in the same condition. 930mV is not enough when running 'cpuburn-a53' meanwhile 950mV is the minimum voltage. When running 'cpuburn-a53' at 1.8G, h6 consumes lots of power and generate such amount of heat that an active cooling is necessary otherwise h6 gets overheat and system crashes. Even with active cooling and heatsink is in low temperature the junction temperature is still quit high that it reaches about 88~90 ℃ . Maybe the high thermal resistance of plastic package causes the problem. |
