I recently bought a GIGABYTE Z390 AORUS PRO WIFI LGA 1151 motherboard and a Intel Core i9-9900K Coffee Lake 8-Core, 16-Thread, 3.6 GHz (5.0 GHz Turbo) cpu. Everything is working fine, but I noticed that compared to the i5 -6600K I had before the i9-9900K never hits the listed turbo speed of 5.0GHz.
The i5 -6600K would hit the turbo speed of 3.90 GHz if I ran the AIDA64 System Stability Test or Prime 95, but the i9-9900K never goes higher than 4.7Ghz. Even on a CINEBENCH single core CPU benchmark it never gets higher than 4.8GHz. I'm wondering if this this due to a setting on the BIOS of the motherboard or if the Turbo Boost of the i9-9900K is working as intended. I read online that max turbo with all cores active is 4700GHz, its just odd that even the single core test in CINEBENCH wont boost higher than 4.8GHz.
