    Intel i5 4690K very high temps with motherboard Gigabyte Z97X-UD3H-BK - BIOS Config problem?


      Hi all. I'm writing this post because I have a temperature problem on my Intel Core i5 4690K. When I play a game, after approximately one hour the game crashes. I passed Intel(R) Extreme Tuning Utility and Prime95 stress tests, and both temps are 90ºC up. I stopped the last stress test at 97ºC.



      I read a lot of posts talking about some problems between Gigabyte motherboards and my Intel processor. For that reason I think there is something wrong with my BIOS configuration (maybe with the voltage settings). I took some screens of my BIOS setup and I'm posting it here. I will really appreciate if anybody can help to me to configure it properly and help me about my temps problems.



      [b]Important: The thermal paste, cooler position, ambient temp are NOT the problem.[/b]

      I'm using the stock Intel Cooler and i'm not overclocking my system.

      I checked the stock CPU cooler, and it's working fine.

      I cleaned the stock thermal compound and I put the new Arctic Cooling MX-4. It helped to low some ºC but not too much.

      I have the air conditioner working all the day in my house, so the temperature in the room where I have my computer is not a problem.

      I updated the BIOS to the lastest version (F7) to see if it fixs the problem, but nothing happened.

          Please see this thread about the overheating of the Intel Core i5 4690k.

          Troubleshooting Intel® Core™ i7-4790K / i5-4690K overheating

          Also check:

          1. Does your processor cooling fan increase?

          2.Do your case fans increase speed?

          3. Does your heat sink actually get hot when the processor reports that temp?

          4. Try running a stress test with the case open to check if bad airflow is the issue.

          Good luck and keep me posted.

            Yes, the CPU fan increases the speed and make a lot of noise when is doing it. But I checked and it's working fine.

            I already ran a stress test with my case open, with the same results (high tems). It's not bad airflow.


            Do you mean should I touch the head sink when the pc is running to see if it's hot? Why?


            I read that is because I have all my BIOS in Auto, and vcore maybe goes high. Im trying to find what is the core voltage stock of my processor and how to put in manual mode with correct setting.

              What is your motherboard temps?


              I ask this because I had to RMA a i7-4790k last week because when I tried those settings that herrmant posted above I bluescreen with the old processor. With motherboard temps at 23c, I could only get the cpu down to 90c - 91c. The new one came in Monday, and didn't bluescreen with those settings above, however I could not get below 90c on the cpu. It was a hot and humid day yesterday when I was lowering the voltage I thought the new cpu was another dud. Today I tested the same thing again since it is cooler out and the motherboard temps are 25c vs (35c yesterday), and so far highest temp the cpu reached is 83c which is what I expected since the i7-4790k in another computer has the same temps with the stock cooler with similar motherboard temps.


              Looking at your pics above, (I don't have a Gigabyte motherboard only have MSI and Asus), looking at your Bios config screen 3rd picture try these settings out.


              1. CPU VRIN External Override:   1.800 ---> 1.700

              2. CPU Vcore: Auto -----> Adaptive Voltage

                                                          --------------------> - (negative) 0.025


              Start with those above.


              I use Wprime-  1024 instead of 32 as a stress test, basically a longer version of Cinebench multithread test to put a load on all cores and threads for 2 minutes to see if the temps are stable. If you do not blue screen with the settings above then slowly lower you CPU Vcore voltage some more until you either bluescreen (unstable due to low voltage) or get to the desire temps that you want. Next voltage drop is Vcore set to Adaptive -(negative) 0.030.


              If yours bluescreen with the settings above try a lower Vcore drop - (negative) 0.010.



              Also for your CPU-z screen second pic. Is it running 3.9 Ghz on all 4 cores? or just a single core? Can you post some CPU-Z shots on the CPU speed under a single threaded load and a full threaded load. Some motherboards like to turbo all 4 cores to its maximum rated speed especially K series CPU. I had that happen to the MSI board trying to run 4 cores and 8 threads at 4.4Ghz with stock cooler.


              Can you post your min and max temps after a stress test you can use realtemp.

                Thanks for your answer. I really thought it was a BIOS problem, but I bought a Cooler Master Hyper 212 EVO. I installed it and now the temps are amazing. At idle is 33ºC, but when I ran the prime95 stress test, I get 62-63º at 100% of CPU usage. I can't believe it, because before this the prime95 showed 90º+ in just 10 seconds. Now it was running more than 6 minutes with 62ºC-63ºC. So the problem was just the stock cooler, maybe it was defective or I don't know. Thanks anyways for your time!

                  I am glad your problem is solved. Sorry for the delay in reply about your previous question, I said to touch the heat sink to see if it actually was getting hot and not just a sensor misread which is quite common on some older chips, and I didn't want to rule out that possibility on a Haswell chip. The stock cooler is meant to keep the chip at or slight below the Tcase MAX value which is 72*c. Note: This does not refer to core temps, and your core temps may be higher than this reading.
