BADRAMA[1:0] - Bad DRAM Marker A
This register implements “failed-device” markers for the enhanced demand scrub
algorithm. Hardware “marks” bad devices. The “mark” is a number between 1 and 18
inclusive. A value of “0 0000h” indicates an “un-marked” rank: all RAM’s are presumed
“good”. Only ranks containing x8 DRAM are “marked”.

BADRAMB[1:0] - Bad DRAM Marker B
This register implements “failed-device” markers for the enhanced demand scrub
algorithm. Hardware “marks” bad devices. The “mark” is a number between 1 and 18
inclusive. A value of “0_0000” indicates an “un-marked” rank: all DRAM’s are presumed
“good”. Only ranks containing x8 DRAM are “marked”.
