Note that the IPDT then reported the test result as "Pass", and only issued a frequency warning (to see which you have to inspect the test log). After running the Intel Processor Diagnostic Tool I discovered that the CPU can go up to 5.1+ GHz. I was confident that the CPU was not overclocked, since I had left all BIOS settings at the default (Auto). Well, I managed to fix the problem by disabling some overclocking settings. How can I determine what causes this problem?ĮDIT: After updating my BIOS from F6 to F8 (latest), the issue has not been resolved. Needless to say, unless I use Power Options to restrict maximum usage to 90%, I end up having the computer crash occasionally, corrupting data and leading to loss of work (besides being very annoying). Compare to the 90% case: Temperature takes 2 seconds to reach 85C, and then about a minute to reach 95C. The crash is very fast: If I start from an idle temp of 35C, there is not enough time for CoreTemp to update the tray icon. The computer does a hard reset without any error message, automatically starts again, and Windows warns me about an unexpected shutdown.ĭoing the last experiment almost always results in a crash (at least 95% of the time). ![]() If I set the maximum power state to 100% and run Prime95, I immediately get a crash. ![]() The system appears to be stable indefinitely like this. This pushes all 8 threads to 100% usage (actually 90% because I've throttled it), and my CPU temperature goes to 95C with 123.5 W of power (CoreTemp 1.0 RC6). I am controlling the CPU load using Windows Advance Power Plan settings, by changing Maximum processor state under Processor power management.Īfter setting the maximum power state to 90%, I run Prime95 with the maximum heat torture test. My computer is crashing when the CPU is put under 100% load, but not when it put under 90% load.
