| 57 | Usually system firmware turns off system memory clock |
| 58 | signals to unused SO-DIMM slots to reduce EMI and power |
| 59 | consumption. |

| 61 | be disabled. |

| 67 | If non-zero, this designates the maximum DDR frequency |
| 68 | the board supports, despite what the chipset should be |
| 69 | capable of. |

| 73 | help |
| 74 | On some boards it may be neccessary to hard reset early |
| 75 | during resume from S3 if the SLFRCS register indicates that |
| 76 | a memory channel is not guaranteed to be in self-refresh. |
| 77 | On other boards the check always creates a false positive, |
| 78 | effectively making it impossible to resume. |
