The problem is a common memory logic problem.
Note: If more than a pair of memory modules from the same memory card are reported missing, replace the FRU that the memory modules plug into first. Otherwise, replace the memory module at the physical location code that is reported.
Use the following table to determine the part number for the field replaceable unit (FRU).
| CCIN or FFC | Type and model | Part number | Description | Location code |
| 219 | 9117-MMA | 15R7433 | 512 MB DIMM, DDR2 | Un-P2-Cx-Cy |
| 219 | 9117-MMA | 15R7436 | 1 GB DIMM, DDR2 | Un-P2-Cx-Cy |
| 219 | 9117-MMA | 15R7439 | 2 GB DIMM, DDR2 | Un-P2-Cx-Cy |
| 219 | 9117-MMA | 15R7445 | 4 GB DIMM, DDR2 | Un-P2-Cx-Cy |
| 219 | 9117-MMA | 15R7448 | 8 GB DIMM, DDR2 | Un-P2-Cx-Cy |
