i am not sure if we should expect too much from EVGA.
Yeah. Their answer was "Unfortunately, we can not guarantee overclock on these or any motherboards beyond the advertised clocks. We test the motherboard to ensure it is properly functioning and beyond this there are various reasons including the CPU itself."
However, in cinebench 20\23 frequency is not dropping down, it holding at 5900. Even 6000 holds on P cores in cinebenches.
But in Linpack and chess Stockfish AVX2 engine its drops to 5800.
Took Apex Z790 from friend for a day to test. Apex holds 5900 on P cores rock solid.
Well, i think i can live with it. Just wanted to clarify things. Seems like it's a EVGA BIOS issue.
