ECC Mode

Select the level of ECC protection. Note: The “Super” ECC mode dynamically sets the DRAM scrub rate so all of memory is scrubbed in 8 hours.

Basic / Super / Disabled / Good / Max / User

DRAM ECC Enable

DRAM ECC allows hardware to report and correct memory errors automatically maintaining system integrity.

Enabled / Disabled

DRAM SCRUB REDIRECT

DRAM SCRUB REDIRECT allows the system to correct DRAM ECC errors immediately when they occur, even if background scrubbing is on.

Enabled / Disabled

DRAM BG Scrub

DRAM scrubbing corrects memory errors so later reads are correct. Doing this while memory is not being used improves performance.

Note: When AMD’s node interleave feature is enabled, BIOS will force DRAM scrub off.

Disabled / 40ns / 80ns / 160ns / 320ns / 640ns / 1.28us / 2.56us / 5.12us / 10.2us / 20.5us / 41.0us / 81.9us / 163.8us / 327.7us / 655.4us / 1.31ms / 2.62ms / 5.24ms / 10.49ms / 20.97ms / 42.00ms / 84.00ms

Data Cache BG Scrub

Allow the L1 Data Cache RAM to be corrected while idle.
