<!-- from fixya rte -->E2111 SBE LOG DISABLE -DIMM 3 - OptiPlex Dell Computers & Internet

Hi
Two most likely causes for this error are
First: the memory module, DIMM3 has worked its way loose and needs to be reseated firmly in its slot with both catches firmly engaged.
Second: The memory module DIMM 3 has become faulty and needs to replaced.
If reseating the DIMM doesn't work try swapping slots with a module of the same size in a different slot and see if the fault follows the module or goes away. If the fault follows the module, eg to DIMM 1, then it is most likely that the module is faulty.
Hope this is helpful, if so would you please register that with Fixya
Cheers
