Memory options

Configuring memory remapping

Use the Memory Remap option to remap system memory that might be disabled due to a failure event,
such as an uncorrectable memory error.
Procedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration
(RBSU) > Memory Options > Memory Remap.
2. Select a setting.
• Remap All Memory—Makes all memory in the system available again on the next boot.
• No Action—Leaves any affected memory unavailable to the system.
3. Save your setting.

Configuring Advanced Memory Protection

Use the Advanced Memory Protection option to configure additional memory protection with Error
Checking and Correcting (ECC). Advanced ECC Support provides the largest memory capacity to the
operating system, and is the required setting when NVDIMMs are installed on your server. Other options
are not supported when NVDIMMs are installed. Selecting one of the unsupported options when
NVDIMMs are installed generates messages that are displayed in the IML, and the NVDIMMs are
disabled until the configuration is set to Advanced ECC Support. When Advanced Memory Protection is
set to Advanced ECC Support, the Advanced Memory Protection option is hidden (greyed out) in the
menu.
Procedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration
(RBSU) > Memory Options > Advanced Memory Protection.
2. Select a setting.
• HPE Fast Fault Tolerant (ADDDC)—Enables the system to correct memory errors and continue to
operate in cases of multiple DRAM device failures on a DIMM. Provides protection against
uncorrectable memory errors beyond what is available with Advanced ECC.
• Advanced ECC Support—Provides the largest memory capacity to the operating system while
protecting the system against all single-bit failures and some multi-bit failures.
• Online Spare with Advanced ECC Support—Enables the system to automatically map out a
group of memory that is receiving excessive correctable memory errors. This memory is replaced
by a spare group of memory.
• Mirrored Memory with Advanced ECC Support—Provides the maximum protection against
uncorrected memory errors that might otherwise result in a system failure. You must install
additional memory to provide mirrored memory to the operating system.
3. Save your settings.
