• QVL/AVL - 3rd party source

  @Jose Luis Pedrosa I had problems finding the RAM modules listed on the ipi.wiki AVL too - they appear to mostly be industrial DIMMs. However, Ampere also has an AVL at https://connect-admin.amper...

• CPU frequency capped to 2.3 GHz instead of 2.6 GHz

  I'm working on updating the firmware and hoping I can tweak the ACPI tables to allow more performance. For example I think it should be possible to enable the "Max Performance" setting, while at th...

• Does the (micro) fan connector on the module work?

  Thanks! I'll try again with a less hacky solution (i.e. this time soldering wires).

• Does the (micro) fan connector on the module work?

  Since FAN_0 isn't wired up, I decided to try buying some micro connectors, adapters and jumper wires and connect the SoC fan to the connector on the module.   Unfortunately it didn't work: t...

• FAN_0 not working?

  According to the COM-HPC module schematics, the FAN_0 header should be controlled by the MMC - I presume according to the SoC temperature. However, I just tested it and despite getting up to over 8...
