What did you exactly istall and execute?I've just tested on a new pi500. arm_freq=3000 (no other settings).
It boots fine, but linpack produces a segfault. Remove the overlock and linpack passes.
Just "sudo apt install hpcc"?
And what command/options?
I want to try it on my 3GHz Pi5.
I only know how to use optimized by AMD rocHPL, it reports 4.7195 TFlops on my MI50 GPU:

I have a 4GB Pi5, perhaps that makes a difference?
I remember threads on 4GB Pi5 being faser than 8GB Pi5, caused by different RAM supplier.
