DRAM ECC Enable

This setting enables/disables ECC (Error Correction Code) checking, a method of checking the integrity of data in DRAM. ECC provides more elaborate error detection than parity; ECC can detect multiple-bit errors and can locate and correct single-bit errors.

4-Bit ECC Mode

This setting enables/disables the 4-bit ECC mode.

DRAM Scrub Redirect

This setting enables/disables ECC Scrubber to correct errors detected in DRAM during normal CPU requests (foreground scrubbing).

DRAM BG Scrub
