Storing the results -allows to boot faster on normal boot and allows to support S3 resume, -as the RAM training results can't be stored in RAM (you need to configure -the memory controller first to access RAM). - -The MRC cache needs to be invalidated in case the memory configuration has -been changed. To detect a changed memory configuration the CRC16 of each DIMM -is stored to MRC cache. -> **Note:** This feature is available since coreboot 4.4 - -### Error handling -As of writing the only supported error handling is to disable the failing -channel and restart the memory training sequence. It's very likely to succeed, -as memory channels operate independent of each other. -In case no DIMM could be initilized coreboot will halt. The screen will stay -black until you power of your device. On some platforms there's additional -feedback to indicate such an event. - -If you find `dmidecode -t 17` to report only half of the memory installed, -it's likely that a fatal memory init failure had happened. -It is assumed, that a working board with less physical memory, is much better, -than a board that doesn't boot at all. - -> **Note:** This feature is available since coreboot 4.5 - -Try to swap memory modules and or try to use a different vendor. If nothing -helps you could have a look at capter [Debuggin] or report a ticket -at [ticket.coreboot.org].
