OrangePI 5 self-reboots running GeekBench 5

[XFer012]

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?

 

Thanks!

Went nicely through for me with 1.8/2.4GHz: https://browser.geekbench.com/v5/cpu/21177042

Only difference is a slightly adjusted kernel with debugfs removed and WiFi support removed entirely. Should not have an impact though.

[XFer012]

Many people run GB without issues @2.4, was wondering where to look for, since mine cannot run over 2.0 which is quite a difference.

[XFer012]

Switched to 150balbes' "Lunar" image (kernel 6.2.0 rc1) and now I can successfully complete Geekbench 5.5.1 @ 1.8 A55 / 2.2 A76

Scores are better as well: https://browser.geekbench.com/v5/cpu/21182173 , expecially considering 2.2 GHz (true speed = 2.246 GHz according to "mhz")

Ok, setting 1.8/2.4 is still OK and completes the test, but real clockspeed is 2276 MHz. That's OK since my A76 pvtm-volt-sel is 5 not 7 (max silicon quality).

Geekbench scores are satisfying https://browser.geekbench.com/v5/cpu/21182824

Issue closed I'd say.
