#### <mark style="color:blue;">**In-Band Error Correction Code (IBECC)**</mark>

In-Band Error Correction Code (IBECC) is a specialized memory protection technology designed to enhance system reliability without requiring the additional physical memory chips traditionally associated with ECC (Error Correction Code). Unlike standard ECC, which utilizes dedicated "side-band" data lanes and extra DRAM chips to store parity bits, IBECC embeds the error-correcting data directly within the standard memory bandwidth. This allows for industrial-grade data integrity on hardware configurations. IBECC protects data against single-bit errors (Single-Bit Error Correction) and detects multi-bit errors (Double-Bit Error Detection) within the existing memory ranks. A small portion of the system’s total available RAM is reserved to store the ECC metadata. This results in a negligible reduction in total usable memory but significantly increases resilience against data corruption.

<mark style="color:blue;">**Enabling IBECC**</mark>

To enable IBECC, enable **Expert Mode** and navigate to **Advanced > Memory Configuration.**

#### <mark style="color:blue;">Secure Boot</mark>

**BIOS Secure Boot** is a security feature that prevents malicious software from loading during your PC's startup. It verifies the digital signatures of boot components against a database of trusted keys. If a signature doesn't match, the system will not boot, protecting against pre-boot malware.

To enable Secure Boot:

1. Go to the **Security** page to set a **Supervisor Password**. Then save and exit.
2. Go to **"Administer Secure Boot"** on the front page to enable secure boot.

After enabling Secure Boot, the system will only boot to signed EFI boot files or Operating Systems.
