Hello, Update for the post. We swapped the CPU and there was thermal paste on the wrong side of the CPU2... After the swap something just broked, and we got these errors:  MEM0001Multi-bit memory errors detected on a memory device at location(s) DIMM_A{x}.PST0091A problem was detected in Memory Reference Code (MRC).UEFI0058An uncorrectable Memory Error has occurred because a Dual Inline Memory Module (DIMM) is not functioning. One of the channels (0,1,2,3) randomly did not work after restarting the server. We tried: swapping memory modules, only using one CPU, BIOS reset.  So it's a replacement.  F
Hello!System hardware:Xeon E5-2673 v3 (x2), 128GB RAMI have a Dell Poweredge 730xD (2cpu). In the past 2 months, we had 3 "crashes" after ~2.5 years error-free operation. From iDrac we got these errors. Before the crash, the logs show the same order. The whole "pre-crash" event occurs in  60sec I found a lot of forum posts about this CPU family on both Intel and Dell forums. It seems to me it's a general problem with these CPUs.  iDrac does not show any hardware-related problem, every component has a green symbol. Edit: Windows only created one BSDO file it shows a ntsokrnl.exe crashed. (So it can be anything, ntskrnl handles every hardware and near hardware things)Things I did until this post: Now I will shut down the server and re-paste the CPU and swapping them.What more can we do? Is there any bug report/know issue about this CPU I did not find? Thanks for helping,F
