Memory option
You can expand server memory by installing PC2-5300 Registered DDR2 SDRAM DIMMs. Each server
supports up to 16 GB of memory using four 4-GB DIMMs.
NOTE: The Advanced Memory Protection option in RBSU provides additional memory
protection beyond Advanced ECC. By default, the server is set to Advanced ECC Support. For
more information, refer to "HP ROM-Based Setup Utility (on page
45 )."
For DIMM slot locations and bank assignments, see "DIMM slot numbering (on page 9 )."
Advanced ECC memory
Advanced ECC memory is the default memory protection mode for this server blade. In Advanced ECC,
the server blade is protected against correctable memory errors. The server blade provides notification if
the level of correctable errors exceeds a pre-defined threshold rate. The server blade does not fail
because of correctable memory errors. Advanced ECC provides additional protection over Standard ECC
because it is possible to correct certain memory errors that would otherwise be uncorrectable and result in
a server blade failure.
Whereas standard ECC can correct single-bit memory errors, Advanced ECC can correct single-bit
memory errors and multi-bit memory errors if all failed bits are on the same DRAM device on the DIMM.
DIMM installation guidelines
CAUTION: Always wear an antistatic wrist strap when working inside the server.
Observe the following guidelines when installing additional memory:
