BIOS Parameters by Server Model

Advanced BIOS Parameters for C460 Servers

Name	Description
C1E	Whether the CPU transitions to its minimum frequency when
	entering the C1 state. This can be one of the following:
	• Disabled—The CPU continues to run at its maximum
		frequency in C1 state.
	• Enabled—The CPU transitions to its minimum frequency.
		This option saves the maximum amount of power in C1
		state.
	Note	This option is used only if is
		enabled.
Memory Configuration Parameters
Name	Description
Select Memory RAS	How the memory reliability, availability, and serviceability
	(RAS) is configured for the server. This can be one of the
	following:
	• —System performance is optimized.
	• Mirroring—System reliability is optimized by using half
		the system memory as backup.
	• Sparing—The system reserves some memory for use in
		the event a DIMM fails. If that happens, the server takes
		the DIMM offline and replaces it with the reserved
		memory. This option provides less redundancy than
		mirroring, but it leaves more of the memory available for
		programs running on the server.
NUMA Optimized	Whether the BIOS supports NUMA. This can be one of the
	following:

• Disabled—The BIOS does not support NUMA.

• Enabled—The BIOS includes the ACPI tables that are required for NUMA-aware operating systems. If you enable this option, the system must disable Inter-Socket Memory interleaving on some platforms.
