My system: Core i5-720, not overclocked.
I'm having an unusual issue for which I hope someone may have some input.
Until yesterday, when my cpu was in an idle state, the clock speed and the core voltage would throttle down as expected since I have EIST and c1e active. The multiplier, at idle, was 9X and the cpu clock speed was about 1198 mhz. And, as expected, when the cpu was under a load (running a game, etc) the cpu and the voltage would "throttle up" as needed.
But since yesterday, according to both cpu-z and Everest, at idle, my cpu is running at just under 2800 mhz and the multiplier is 21x (oc'd 4 percent). But my cpu voltage seems to be OK (.984v) which is normal, or slightly high, at idle. It appears that, for whatever reason, EIST and/or c1e are not throttling down the cpu clock speed as it did previously. I checked BIOS and confirmed that EIST is active.
Task manager shows that at idle, the cpu usage is 0-1 percent. My core temps are in the 30s and low 40s (celsius), which is normal for my system. It's just that the cpu clock is running "full-bore" and it shouldn't be when idle.
Is there something else I can check? Thanks for any information.
