HP ProLiant ML570 Generation 2 Server Memory Installation Guide

Memory
This process occurs without intervention or server interruption, and enables you to
replace the degraded DIMM at your convenience during a regularly scheduled
shutdown. Uncorrectable errors are detected at the bank level rather than the DIMM
level, so if an uncorrectable error occurs, all DIMMs in the bank must be replaced.
As long as no errors have occurred on the memory board, the system periodically
switches which set of banks it reads from to be sure that both sets are monitored for
memory errors.
DIMM Installation Requirements
In addition to the DIMM configuration requirements for advanced ECC memory,
observe the following DIMM configuration requirements when installing DIMMs for
single-board mirrored memory:
•
•
•
Install only one board. The board must be installed in memory board slot 1.
Bank C mirrors bank A, and bank D mirrors bank B. Banks A and C must always
be populated.
DIMMs in the mirrored banks must be configured identically to the banks they
are mirroring. Corresponding banks (for instance, bank A and bank C) must be
populated with DIMMs of the same capacity.
IMPORTANT: If any of the previous requirements are not met, the system automatically
switches to advanced ECC memory and displays an error message during POST.
