Error Name
The MCH determined that a
normally “correctable” error
could be an aliased (x8
only) full device failure plus
an additional single bit
error.
In mirrored mode, the MCH
determined that a normally
“correctable” error could be
an aliased (x8 only) full
device failure plus an
additional single bit error.
During a Sparing copy read
from the failing DIMM the
MCH determined that a
normally “correctable” error
could be an aliased (x8
only) full device failure plus
an additional single bit
error.
During a Patrol Scrub, the
MCH determined that a
normally “correctable” error
could be an aliased (x8
only) full device failure plus
an additional single bit
error.
The MCH detected
uncorrectable data with
good CRC.

Log Register
Re-read once.
If ECC is uncorrectable with
good CRC after re-read, then
poison the data in memory
and to the requestor.
If correctable after re-read,
then correct the data in
memory and to the
requestor.
First redundant read to
branch X fails.
MCH performs a fast reset on
both branches X and Y.
If both branches pass, then
replay on branch Y.
If branch X fails the disable
branch X and replay on
branch Y.
If both branches fail or
branch Y fails disable branch
X and poison data. Under
these conditions we get an
M1 error.
Second redundant read to
branch X fails with an
uncorrectable error.
Perform fast reset and
disable branch X and replay
on branch Y.
Re-read once.
If ECC is uncorrectable with
good CRC after re-read, then
poison the data in the spare
DIMM or the off-line branch.
If correctable after re-read,
then correct the data in the
spare DIMM or the off-line
branch.
The patrol read is dropped.
Re-read once.
If ECC is uncorrectable with
good CRC after re-read, then
poison the data in memory
and to the requestor.
If correctable after re-read,
then correct the data in
memory and to the
requestor.
Does not include poisoned
northbound data.
