Single bit warning errors by them selves mean very little other then the
memory found an error and corrected for it.  However, IF you see many of
these errors, then there is a more serious issue.  That would indicate
that you have a bad dimm or a bad dimm card.  To test, just swap out
dimm2-b with another dimm and see if the error follows the dimm or stays
with the slot.  If it stays with the slot, you need a new dimm card/MB,
if it follows the dimm, you need a new dimm.


Again, a few of these warnings mean nothing other then the ECC for your
memory is working as designed.  Many of these warnings means you have
bad memory or bad memory riser/MB.
