    Troubleshooting Dealing with HPMC (Uncorrectable Error) HPMC Caused by a Data Cache Parity Error For example, an HPMC interruption is forced when a data cache parity error is detected during a load instruction to the memory address space or during a data cache flush opera- tion.

  • Page 99: Hpmc Caused By A Multi-Bit Memory Parity Error

    Troubleshooting Dealing with HPMC (Uncorrectable Error) HPMC Caused by a Multi-Bit Memory Parity Error An HPMC interruption is forced when a multi-bit memory parity error is detected during a “DMA read” operation or fetching an I/D cache line (32 bytes). Table 4-6 shows an example of the HPMC error information retrieved from Stable Storage by the PIM command during the Boot Administration environment.

    Troubleshooting Dealing with HPMC (Uncorrectable Error) Determining the Faulty Memory Card Memory is configured in a contiguous fashion starting at a base hexadecimal address of 0x00000000 to a maximum of 0x3FFFFFFF (1024MB). Memory is installed on the Model 744 in a single stack of up to four memory cards of 16MB, 32MB, 64MB, 128MB or 256MB capacity.

  • Page 101: Physical Memory Slots

    Troubleshooting Dealing with HPMC (Uncorrectable Error) NOTE: When mixing memory cards of different capacities, 128MB and 256MB cards must always be in the lowest numbered physical slots. Physical Slot 3 Physical Slot 2 Physical Slot 1 Physical Slot 0 Figure 4-2 Physical Memory Slots 4-31...

  • Page 102: Logical Memory Slots

    Troubleshooting Dealing with HPMC (Uncorrectable Error) During the boot process, when the system sizes the memory to create a memory map, the memory slots are divided into eight logical slots. For better understanding, they will be referred to from herein as logical slots 0 through 7. The system maps two logical slots to each physical slot as shown in Table 4-7.

  • Page 103: Memory Configuration Example

    Troubleshooting Dealing with HPMC (Uncorrectable Error) After the 256MB cards are sized, the 128 and 64MB cards are sized in a similar manner. Then the sizing progresses to the 16MB segment of memory in the lowest numbered logi- cal slot, then the 16MB segment in the next highest numbered logical slot, and so on, until all of the memory has been mapped.
  • Page 104 Troubleshooting Dealing with HPMC (Uncorrectable Error) A worksheet is needed to determine the address ranges associated with each of the logical slots. In the example in Figure 4-3 below, the memory configuration example shown in Table 4-8 has been used. In this example, we first determine the memory cards that are installed in each physical slot.
