Hello,
I am running Armbian 23.05 "minimal" (with the provided kernel 5.10.110) on my OrangePI 5 4GB. Upgraded all packets to latest.
When trying to run GeekBench 5.5.1 ARM Preview, it reboots when approaching the end of multicore tests, with "performance" governor and default speed range (0.4 - 2.4 GHz for A76).
Same goes if I drop the max clock speed to 2.2 for A76.
After dropping to 2.0 GHz max, it runs fine; but this hurts performances quite a bit.
I tried various power sources, including a bench PSU which can reliably supply up to 30A (but I only see a few spikes over 2A).
The board has a large heatsink installed with thin 3M thermal pad; temperatures stay under 54 C under full load.
I suspected a bad silicon, but it does not look bad, should ad least reach 2.2 GHz:

Any suggestion?
