Enabling the Trusted Platform Module
1.
When prompted during the start-up sequence, access RBSU by pressing the F9 key.
2.
From the Main Menu, select Advanced Options .
3.
From the Server Security Menu, select Trusted Platform Module .
4.
From the Trusted Platform Module Menu, select TPM Functionality .
5.
Select Enable , and then press the Enter key to modify the TPM Functionality setting.
6.
Press the Esc key to exit the current menu, or press the F10 key to exit RBSU.
7.
Reboot the server.
8.
Enable the TPM in the OS. For OS-specific instructions, see the OS documentation.
CAUTION: When a TPM is installed and enabled on the server, data access is locked if you
fail to follow the proper procedures for updating the system or option firmware, replacing the
system board, replacing a hard drive, or modifying OS application TPM settings.
For more information on firmware updates and hardware procedures, see the HP Trusted Platform Module
Best Practices White Paper on the HP website ( http://www.hp.com/support ).

Memory configurations
This server supports 2 GB to 128 GB of Advanced ECC system memory using 1-GB, 2-GB, 4-GB, and 8-
GB registered DDR-2 DIMMS across 16 DIMM slots. Depending on the quantity and speed of DIMMs
populated, memory bus speeds can be 533-MHz, 667-MHz, or 800-MHz. The memory bus speed is
determined by using the following two-step process.
1.
The BIOS interrogates each DIMM installed in the system and sets the memory bus speed to the least
common denominator of the DIMM speeds detected, regardless of the RBSU menu option selected.
For example, with 667-MHz and 800-MHz DIMMs installed, this first step should complete with the
memory bus speed set to 667 MHz regardless of how many DIMMs are installed on each processor.
2.
With this step, the following RBSU menu option settings determine the actual memory bus speed that
is selected.
o
Menu Option 1 = Auto (default)
Memory bus speed is determined by the number of DIMMs installed for each processor:
—
Auto Case 1: Four or less DIMMs = 800-MHz memory bus speed provided that all DIMMs
detected in step 1 are rated for 800 MHz.
—
Auto Case 2: Six DIMMs = 667-MHz memory bus speed provided that all DIMMs detected in
step 1 are rated for 667 MHz or greater.
—
Auto Case 3: Eight DIMMs = 533-MHz memory bus speed provided that all DIMMs detected
in step 1 are rated for 533 MHz or greater.
