Output
| Field | Byte length | Byte offset | Register | Description |
|---|---|---|---|---|
| Status | 4 | 0 | See _DSM Method Output. | |
| Module Health | 2 | 4 | Byte 0: MODULE_HEALTH_STATUS0 (0, 0xA1); Byte 1: MODULE_HEALTH_STATUS1 (0, 0xA2) | Detailed information regarding the NVDIMM-N module's health. |
| Module Current Temperature | 2 | 6 | The module temperature in degrees Celsius. The minimum value is 0. This information is retrieved from the temperature sensor on the NVDIMM-N’s Serial Presence Detect EEPROM. | |
| Error Threshold Status | 1 | 8 | Byte 0: ERROR_THRESHOLD_STATUS (0, 0xA5) | Status regarding the error thresholds on the NVDIMM-N module. |
| Warning Threshold Status | 1 | 9 | Byte 0: WARNING_THRESHOLD_STATUS (0, 0xA7) | Status regarding the warning thresholds on the NVDIMM-N module. |
| NVM Lifetime | 1 | 10 | Byte 0: NVM_LIFETIME (0, 0xC0) | The last known non-volatile memory lifetime percentage value. |
| Count of DRAM Uncorrectable ECC Errors | 1 | 11 | Byte 0: DRAM_ECC_ERROR_COUNT (2, 0x80) | The number of uncorrectable ECC errors detected by the platform from the NVDIMM-N module. |
| Count of DRAM Correctable ECC Error Above Threshold Events | 1 | 12 | Byte 0: DRAM_THRESHOLD_ECC_COUNT (2, 0x81) | The number of correctable ECC threshold-exceeded events detected by the platform from the NVDIMM-N module. |
