2600k keeps downclocking itself

post #1 of 4
Thread Starter 
I've been plagued with this problem the past week and it's really annoying. If my PC is on a long while then my CPU downclocks itself to 1.6ghz and never goes up during cpu intensive tasks. The only way to bring it back to normal is to restart the PC. Anyone have this problem and can help? I've tried putting everything to default and it still does it.

I had this issue as well and mine problem turned out to be a BIOS issue with Intel Speedstep (EIST) and C1, C3, and C6 power states. Once my processor was operating at a reduced voltage and frequency, it would not come back out of it. I ended up flashing an up to date Bios to my motherboard. The motherboard was using a P67 chipset.


BELOW INFO IS A WORKAROUND, NOT A SOLUTION!
If you dont want to go through the hassle of troubleshooting the issue, you can turn off Intel SpeedStep and C1, C3, and C6 states and the processor will run at full power and frequency. It will not throttle down at all. Obviously, this will generate the most heat and power consumption, but the original issue will go away.

I just tried your solution before posting and it didn't work :[ I've updated my bios too and still no dice.

Figured it out. I flashed an older bios that I was using and it works now.

*nevermind it seems that battlefield 4 is the cause of the problem. I have no clue on what to do with that?


update 2 * : Was recommended to use throttle stop and that completely fixed the problem. No more downclocking problems. After disabling BD PROCHOT my CPU never downclocked again.
