Configuring Advanced Memory Protection

You can configure additional memory protection with ECC (error checking and correcting).

Advanced ECC provides the largest memory capacity to the operating system.

To configure advanced memory protection:

1. From the System Utilities screen, select System Configuration→BIOS/Platform Configuration

(RBSU)→System Options→Advanced Memory Protection and press Enter.

2. Select one of the following options:

• Advanced ECC Support (default) — Configures the largest memory capacity to the operation

system while protecting the system against all single-bit failures and some multi-bit failures.

This option provides up to 4–bit error correction and enhanced performance over Lockstep

mode.

• Online Spare with Advanced ECC Support — Configures a 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 — Configures maximum protection against

uncorrectable memory errors that can otherwise result in a system failure.

• Lockstep Mode with Advanced DDDC Support — Configures maximum data protection

by correcting multiple-bit memory errors (using Double Data Device Correction (DDDC)

support) that Advanced ECC mode cannot detect. Lockstep mode improves system

reliability and availability.
