that's a bug from CB :D I have seen such things, on ryzen 7 2700x@4.2Ghz I got a score about 18k but rendered image had some wrong rendering in colors, delete it.
For CPU frequency, yeah but my main problem is for memory, I tried higher frequencies like 3533 and 3600 with loose timings like 19-19-19 but sadly even with 1.9v for mems it didn't boot, really idk what to do for getting better scores on ryzen.
