According to the data provided, the maximum ratio the CPU reached is 45x and clkin (bus) = 100 MHz.
So I have to admit, that this is a total mystery to me.
Could you please use the latest Beta build (v4.23-1990) and perform more test runs and watch the maximum value - what's the exact maximum clock reported and if it's the same on all cores ?
It doesn't spike like that during prime95 or OCCT but during World of Tanks gaming.
Does it always show the exactly same max clock value (5159 MHz) and on all cores ?
Does the Debug File you attached before really capture the run when the spike occurred ?
I believe the game does somehow interact with the (bus) clock measurement method in HWiNFO. I also think other tools (like CPU-Z) might be affected as well, but there's no way how to check the history of values recorded (max) there.
I don't have a solution for this right now, but I think I'll implement a new setting in HWiNFO which when used will measure the bus clock only once during runtime, so later when starting an application (which might interfer with it), this won't happen.
The next release will add a setting called "Periodic polling", which when disabled will help to mitigate/fix this problem.
Glad I can help with something and thank you Martin.
Thank you too for reporting this issue and for the tests.
Please try the new v4.24 and disable the "Periodic polling" setting.
Currently testing 4.24v. With Periodic polling ON, that strange number did came out but when it's disabled, though with just 20 minutes of test time or so, everything's normal. So far so good I think. I'll report if there's any anomaly.
Thanks for your feedback.
