When i use CPU-Z stress test, my i7 6700k goes to 100% Utilisation, and ill get a score of 8500+ but it will then continues to drop from 100 to 90 then to 80 until it reaches 40 and stays at 40% utilisation. I also ran a Passmark performence test and getting low Prime numbers scores of 20 and physics score of 450. I also ran a geekbench 4 cpu test and got 13900, where others get 16-17000 on stock speed, but on aida64 im geting perfect benchmarks scores, also with cinebench with a score of 860. Can any one help me? Any help is greatly appreciated.

Temps are always below 60c.

Edit
If i stop and restart the benchmark it will stay at 40% utilisation until i close and restart CPU-Z then it will go back to 100% and then start to drop all over again.

Thanks for the reply!

But, my temps are always below 60c, and it happens within 1 minute.

Take a look thru BIOS and see if there are any settings that would cause that. I can't think of any other reason that would happen. Short of defective components, I mean.

Looked through the bios, not features that will effect it. I can run prime95 at 100% utilisation constantly without any drops, i can also run aida64 at 100% no drops. Just CPU-Z stress test will lower its utilisation util i reaches 40%.

Weird thing is, if i stop and start the benchmark again, the utilisation will only go to %40-50 and wont go up to %100 giving me a very low multicore score, but if i cloae and restart CPU-Z and start a stress test, it will go to 100% utilisation and dip again. Dunno what would cause that
