Re: Haswell temperature problems with pstate

I removed thermald as it wasn't doing anything.
In my opinion things are bad for reasons I fail to get: it randomly get to high temperatures (like 80°C) with no apparent reason.

Re: Haswell temperature problems with pstate

try:

cat /sys/devices/system/cpu/intel_pstate/min_perf_pct > /sys/devices/system/cpu/intel_pstate/max_perf_pct

that locks down the cpu to minimum power usage. it really shouldnt bump to 80C that way. if it does, something odd is going on (potentially a pstate bug)

(to reset: echo 100 > /sys/devices/system/cpu/intel_pstate/max_perf_pct)

this is kinda like the cpufreq powersave governor, except it uses pstate.

Re: Haswell temperature problems with pstate

I'll try that when I'll get temperatures spikes; in this way I'll see if it's a pstate bug, based on if temperatures whether or not decrease.
