  1. 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.
  2. 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")
  3. 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.
  4. 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: root@orangepi5:~# dmesg | grep pvtm [ 6.624098] rockchip-pvtm fda40000.pvtm: pvtm@0 probed [ 6.624154] rockchip-pvtm fda50000.pvtm: pvtm@1 probed [ 6.624207] rockchip-pvtm fda60000.pvtm: pvtm@2 probed [ 6.624270] rockchip-pvtm fdaf0000.pvtm: pvtm@3 probed [ 6.624321] rockchip-pvtm fdb30000.pvtm: pvtm@4 probed [ 7.352652] cpu cpu0: pvtm=1487 [ 7.352872] cpu cpu0: pvtm-volt-sel=4 [ 7.362528] cpu cpu4: pvtm=1723 [ 7.366667] cpu cpu4: pvtm-volt-sel=5 [ 7.376888] cpu cpu6: pvtm=1731 [ 7.381119] cpu cpu6: pvtm-volt-sel=5 [ 7.561843] mali fb000000.gpu: pvtm=881 [ 7.563822] mali fb000000.gpu: pvtm-volt-sel=3 [ 7.612340] RKNPU fdab0000.npu: pvtm=896 [ 7.617305] RKNPU fdab0000.npu: pvtm-volt-sel=4 Any suggestion? Thanks!
