Greetings all,

I am playing with OC on my i9-9900K ROG Z390E.  I'm using ASUS ROG's AI tools to OC. However, I have been experiencing BSDs that can't explain.  I finally caught one of the messages while running a stress test using Intel's Extreme Tuning Utility running the AVX test for 30 minutes.  This was the BSD's error code, which I captured using the QR code:

IRQL_not_less_or_equal

Here's MS's report on fixing it:

How to fix Error 0xA: IRQL_not_less_or_equal (microsoft.com)

It was interesting that the anti-virus was pinged as a possible cause.  Does AV software affect overclocking? 

After the crash, ASUS AI throttled the OC from 41% (5000 GHz) down to 38% (4900 GHz).  I'm running the AVX stress test again.  CPU Core V is holding at 1.305.  CPU Package Temp is running mid to upper 70's with a peak of 82C (3 different sources: Intel ETU, CPUID HWMonitor, and Core Temp v1.16)  However, ASUS's ROG software is reporting a steady CPU temperature of 65. 

Is a CPU package temperature in the upper 70s with peak of 82C acceptable?

Thanks for your help!
