Hi List, I've been getting the following EDAC memory errors EDAC MC0: CE page 0xeb0dd, offset 0x0, grain 4096, syndrome 0x45, row 3, channel 0, label "": i82875p CE and from this seeing that these errors have been corrected. Checking cat /sys/devices/system/edac/mc/mc0/csrow3/ch0_ce_count gives me a count of 4 thus I now know that csrow3 - ch0 is the problem My question is, how does this map to the on board labels DIMM 1A DIMM 1B DIMM 2A DIMM 2B Am I correct in assuming csrow 3 is DIMM 2B? Also I have just discovered that both the OS drives sda and sdb have huge number of errors shown on the SMART records - can this relate to the memory errors?? - I am just really surprised to have two drives show almost identical number of errors at the same time, yet no apparent data errors - Drives are ATA ST380013AS 74.53 GB TIA for your insightful comments
