Subject: Got my first EDAC error today
Got my first error report from the shiny-new EDAC driver
today. A kWriteD window popped up and displayed:
EDAC MC0: UE page 0x2c, offset 0x0, grain 4096, row 0, labels
"": i82860 UE
Great. Now where do I find how to interpret these error reports?
Some questions:
Does your system have ECC ram? If you don't have ECC and/or your chipset
is not supported EDAC will pretty much only check PCI parity. Given
that it is reporting i82860 I would guess that your chipset is supported,
and that it believes that you have ECC>
UE means uncorrectable error which means that more than 1 bit was
messed up in your memory, generally you won't get these without getting
lots of single big (CE) errors.
You can check /proc/mc/0 that may give you better information, where the
"" is is supposed to be a label to the dimm location on the motherboard,
no one has yet mapped the locations that will be listed to actual locations
on most motherboards.
Steve,
fyi: I posted a week ago:

no responses here, so I checked on fedora-forum: see some info there:

I still don't know if this is a true indication of bad ram, or is it
just that the module is loaded incorrectly when I don't have ecc ram ?
Note that on my machine, the /proc/mc folder/stats does not exist.
Do you have such an interface ? what does it say ?
