Certain models and populations of DIMMs do not function under either coreboot or the proprietary BIOS. These failures may also be contingent on the exact PCB revision and / or CPU model installed. A full list of bad configurations encountered thus far is available below:

These configurations should have been mentioned on HCL if they work in some situations.

Known Bad Configurations

These configurations should have been mentioned on HCL if they work in some situations.
