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.
