Advanced ECC memory configuration

Advanced ECC memory is the default memory protection mode for this server. Standard ECC can detect and correct single-bit memory errors and only detect multi-bit memory errors. When multi-bit errors are detected using Standard ECC, the error is signaled to the server to halt the server.

Advanced ECC protects the server against some multi-bit memory errors. Advanced ECC can detect and correct up to 4-bit memory errors if all failed bits are on the same DRAM device on the DIMM.

Advanced ECC provides additional protection over Standard ECC because it is possible to correct certain memory errors that would otherwise be uncorrected and result in a server failure. Using HP Advanced Memory Error Detection technology, the server provides notification when a DIMM is degrading and has a higher probability of uncorrectable memory error.
