OCCT i7 3770K Temperature and Frequency

post #1 of 2
Thread Starter 
Hi people, I'm currently in the process of overclocking my 3770K and there are two issues I'd like someone with experience to address. The first thing that concerned me was the fact that one of my cpu cores runs warmer than the rest. CPU Core #1 is sometimes 9 to 10 degrees warmer than my coolest core. Here is a screenshot where you can see a graph of core temperatures on the right side in the middle.



Before I ran this test the blue screen of death occurred, signifying the processor core #1 had an error. I was running 4.2Ghz @ 1.104v at the time and as you can see in this image I bumped the voltage up to 1.150v. The test completed successfully without any errors or blue screen, but once the cpu went back to idle I noticed something that was odd. During idle the frequency was changing rapidly. Here is my screenshot to show you on the top right graph.



In my BIOS I have turned on C1E and other C functions but disabled EIST and monitor function. I was expecting the frequency to increase once in a while, but not as rapidly. Is this normal?

It's normal for the temperature of cores to be radically different. Mainly because most applications will use only 1-2 cores hence making those 2 cores rather hot as the other cores aren't really being used. You should look at the CPU Package temperatures meaning the overall temp of the CPU with all 4 cores, usually it's the average of the 4.

It is also normal for the frequencies to be changing rapidly as the processors scale up or down depending on the situation. So if you are idle, then the frequency minimizes, but as soon as some background job needs more power, it will scale up at once, then scale down again after the task is done. When gaming or running some demanding applications, the processor will remain at the desired maximum frequency.

If you're not already subscribed to it, I suggest you take a look at this thread. Follow the guide on how to overclock and you can post your questions there.

Hope this helps. Cheers.
