Î DRAM SCRUB REDIRECT [Disabled]
Use the DRAM SCRUB REDIRECT option to enable the system to immediately correct
DRAM ECC errors when they occur, even when background scrubbing is on.
Î
Disabled D EFAULT
System cannot immediately correct DRAM ECC errors
Î
Enabled System cannot immediately correct DRAM ECC errors
Î DRAM BG Scrub [Disabled]
