<BODY style="MARGIN: 4px 4px 1px; FONT: 10pt Segoe UI">Thank you peter for the input...I don't think its the motherboard as I have 5 of these boxes and they all experiencing the same problem (running the latest bios). I tried switching the RAM around and did manual timing at 667 in the BIOS, hope this fixes the problem. Kingston won't be too happy if I tell them that there memory is not working in my systems specially when we talking about 512GB of memory. Let's see what happens, I will report back as I monitor this situation.<BR><BR>>>> Peter Kjellström<cap@nsc.liu.se> 8/22/2011 9:36 AM >>><BR>On Monday, August 22, 2011 01:36:11 PM Lisandro Grullon wrote:<BR>> Dear List,<BR>> I have been getting system crash, syslog is reporting the following in<BR>> stdout...please advise.<BR><BR>Sure, please don't use "reply" when starting a new thread.<BR><BR>> Message from syslogd@saturn at Aug 21 03:38:08 ...<BR>> kernel: Northbridge Error, node 0<BR><BR>As for this, most likely one or several bad DIMMs (or possibly bad MB).<BR><BR>/Peter<BR><BR>> Message from syslogd@saturn at Aug 21 03:38:08 ...<BR>> kernel:ECC/ChipKill ECC error.<BR>> <BR>> Message from syslogd@saturn at Aug 21 15:23:47 ...<BR>> kernel: Northbridge Error, node 0<BR>> <BR>> Message from syslogd@saturn at Aug 21 15:23:47 ...<BR>> kernel:ECC/ChipKill ECC error.<BR></BODY></HTML>
