Configuring The Memory - HP ProLiant DL580 Maintenance And Service Manual

70 HP ProLiant DL580 Generation 3 Server Maintenance and Service Guide
•
All general memory requirements apply ("General memory configuration
requirements" on page 62).
•
Hot-plug RAID memory is only supported with four memory boards.
•
All four memory boards must have the same amount of total memory.
However, each board can have different DIMM configurations as long as
they have equal total size. Any deviation from this rule results in the server
defaulting to Advanced ECC ("Advanced ECC memory" on page 64).
•
Hot-replace operations are supported.
•
If you remove a board while the server is running and do not replace it, the
server defaults to Advanced ECC on the next reboot.

Configuring the memory

Configuring the memory system of the server requires configuring both hardware
and software.
To configure the memory:
1. Install the correct amount of memory for the desired AMP mode. For a list of
AMP options, refer to "Memory Options." For more information, refer to
"General Memory Configuration Requirements (on page 62)."
2. Test the DIMMs for all AMP modes, except Advanced ECC, before
configuring the AMP mode in RBSU. The two testing methods are:
– POST memory test (on page 70)
– ROM-Based Diagnostics test ("ROM-based diagnostics" on page 71)
3. Select the AMP mode ("Selecting the AMP mode" on page 71).
POST memory test
1. Power on the server.
2. Press the F9 key, when prompted, to enter RBSU.
3. Select Advanced Options.
NOTE: If the total amount of memory has changed, the POST
Memory Test will run automatically. Additional memory testing is not
necessary.
