HP also recommends testing new DIMMs. To test DIMMs and configure memory:
1. Power on the server.
2. Press the F9 key to enter RBSU.
3. Select Advanced Options.
4. Change POST Speed Up to disable.
5. Press any key to return to the RBSU main menu.
6. Select System Options.
7. Select Advanced Memory Protection.
8. Select the desired memory mode.
9. Press the ESC key twice to go back to the main RBSU menu.
Memory
10. Press the F10 key to exit RBSU. The server reboots and tests all memory in the
system.
11. Once the memory has been tested, re-enable POST Speed Up for faster system
boot, if desired.
IMPORTANT: To reconfigure the memory mode after initial setup, you must reboot the
system and enter RBSU.
