What can be wrong? ? ? ? ? ?

Cinebench first run is always 2050 points, then next 1940 and third 1850. Then i wait some minute run again and is 2050 points agian. Its not temps issue,,because temps are always on cinebench 60C. Any ideas?

My uefi all is stock,MCE DISABLED,Intel Turbo Enabled





9900K and Asus Prime Z390-A
 
yeah i checked no other processes working . Its 2050 points, then finish,immidiatelly clicking on next test 1940points,then immidiatelly again and 1840 points. Then i wait 5 seconds and again 2050 points. No other processes. Any ideas? Maybe i am clicking too fast after finished test?
 
What motherboard are you using? Your CPU temps may be good, but perhaps your vrms are getting heat soaked.

i enabled MCE and scores are 2150 consistent

MCE automatically adjusts several bios settings for you but they are totally undocumented changes. We believe they automatically set power limits past stock, which is why it is stable.
It's usually recommended to disable MCE and set all power limits manually and then set your loadline calibration and current limit (amps) and current protection limits manually as well.
 
Yeah but kepping MCE ON when my scores are higher and not fluctuating its not bad etc?
 
MCE is effectively an automatic OC - it usually picks voltages which are higher than necessary.
 
Doesnt MCE also set that to 5ghz all cores? Mgty could be seeing the fluctuation based on the core turboing and other processes running. But with MCE everything is overclocked to 5ghz so its stable
 
MultiCore Enhancement basically puts all cores at max turbo bin automatically. on my z370 and 8700k it basically puts them all to 4.7 in stock operation that cpu should only go to 4.3 all cores. all the motherboard makers have some form of it now in my gigabyte board its like a CPU upgrade or some dumb thing
