OK I know that this matter is widely discussed already but I am at a loss... Got a 9700K yesterday on an Asus ROG Z390 H Gaming with the latest bios version, dated yesterday. With default settings or auto or whatever, the CPU doesn't go beyond 3.9GHz in any Windows situation (gaming, AIDA64 etc). I have tried -almost- anything in BIOS disabled and enabled all the relevant options (asus multicore, 5G OC setting, TPU, C states etc), the only thing that seems to work is disabling SpeedStep and Speed Shift options which allows the CPU to work -constantly though- at 4.6GHz max. 4.9 or 5GHz are out of the question I don't know if there is any way to see these numbers. For starters I only want boost to work as intended and not get the stupid limit of 3.9GHz. Hell, my i7 4790 boosted at 4GHz... Any suggestions or ideas are welcome.
