Memory Faults
A variety of features play a role in how the memory subsystem is configured and
how memory faults are handled. Understanding the underlying features helps you
identify and repair memory problems. This topic describes how the server module
deals with memory faults.
The server module uses advanced ECC technology that corrects up to 4 bits in error
on nibble boundaries, as long as the bits are all in the same DRAM. On some DIMMs,
if a DRAM fails, the DIMM continues to function.
