I was running single core benchmark in cinebench R23 . I set affinity in task manager to cpu6, cpu7 (core 3) and i saw that there is something wrong with it – this is supposed to be my fastest core however the effective clock is very low, and the benchmark score is the worst of all cores.
What can i do about it? I tried manually clearing bios cmos and it didn't help. Setting cinebench priority to "realtime" also doesnt change anything.
My motherboard is ASROCK B650M HDV M2, max temp on cpu during multi core workload is 74 celsius. Im running latest AGESA version, windows 11, updated chipset drivers.
On second screenshot there is a core 2. It works properly in contrast to core 3.
