Error Name
In mirrored mode, the MCH
detected uncorrectable or
poisoned data with good
CRC.
The MCH detected
uncorrectable data with
good CRC from the failing
DIMM rank during a sparing
copy.
During a patrol scrub, the
MCH detected uncorrectable
data with good CRC.
The MCH detected an
“Alert” or corrupted write
acknowledgement on the
first attempt at an FB-DIMM
memory access packet or
on the replay of a
redundant FB-DIMM
memory access packet.
The MCH detected an
“Alert” or corrupted write
acknowledgement on the
first attempt at an FB-DIMM
configuration write
command or on the replay
of a redundant FB-DIMM
configuration write
command
The MCH detected a
northbound CRC error on
the first attempt at a
configuration or memory
read or on the replay of a
redundant configuration or
memory read.

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.
Does not include poisoned
northbound data.
The patrol read is dropped.
Non-redundant or 1st
attempt: Fast reset and
Initiate replay.
Redundant replay or fast
reset time-out: auto-
degrade.
1st attempt: Fast reset and
Initiate replay.
Redundant replay: auto-
degrade.
1st redundant memory read:
re-read once from other
image.
Replay redundant memory
read: auto-degrade
All others: fast reset and
initiate replay from the same
image, branch, or channel.
