Avg here is 1300 pts multi.

Without any tweaks, stock bios setting (mb being B850-f) I'm getting around 900.

I'm getting 1200 (when I'm lucky). Temps are 75c here. I usually otherwise get around 1140 or something.

Not using Game mode, Performance mode or whatever in bios settings. Why am I getting so poor results?
