| Usually system firmware turns off system memory clock |
| signals to unused SO-DIMM slots to reduce EMI and power |

| On some boards it may be necessary to hard reset early |

| a memory channel is not guaranteed to be in self-refresh. |
| On other boards the check always creates a false positive, |
| effectively making it impossible to resume. |
