Any known issues with Intel XTU stress test of AVX2?

I can't seem to run a AVX2 stress test in Intel Extreme Tuning Utility with my i9 9900k on a ASRock Z390 overclocked to 5.0GHz all core, no AVX offest. System doesn't BSOD but hangs, have to reset PC. I passed every other stress test on my i9 system...My i7 8700k system on a Gigabyte Z390 can run the AVX2 stress test overclocked 4.9GHz all core, no AVX offset. 8th and 9th gen Intel CPUs can run Intel AVX2 according to their own spec sheet. Has anyone else had this issue?

Hello Steveo1481

 

Thank you for posting in the Intel Community.

 

The feature Intel® AVX2 comes with the Intel® Core™ i9-9900K Processor (https://ark.intel.com/content/www/us/en/ark/products/186605/intel-core-i9-9900k-processor-16m-cache-...), it would be important confirming that the BIOS settings of the ASRock Z390 have the enable the feature as well if you need assistance please contact ASRock* support (https://www.asrock.com/support/).

Thanks for responding Leo​C but my ASRock Z390 Extreme 4 does not have an option to enable/disable AVX/AVX2/AVX512...And when I try to run a AVX2 stress test in Intel's own software (XTU) with no AVX offset it freezes my PC...??

All software, drivers, Windows 10 and BIOS are up to date. The thing is I can run the Intel XTU AVX2 stress test on another PC I have with a i7 8700k in it and it passes no problem. How is an overclocked 6c/12t chip a year older, passing but not a overclocked 8c/16t​ CPU??

Hello Steveo1481

 

Thank you for the clarification, is it possible for you to test the system without overclocking and run the following tools:

 

 Intel® Processor Identification Utility (please share pictures of the outcome):

Once you complete the test please provide me with the outcome
