ffff880068bc3d30 versus ffff88006abc3d30. A single bit change like this is very very often due to a hardware problem.
This is new machine based on haswell processor and Z series chipset. I can replace any part of system by guarantee if you can help me prove to seller that this part has defect. Any idea how I can do it?
You could try running memtest86 for a very long time (days). I can't think of any other way which would convince the seller, sorry :(
A single bit flip is most likely to be bad memory if its hardware. It could be other things but you would expect to see a machine check event from a CPU cache fault or thermal problem, and other diagnostics from things like SATA cable problems. I would definitely give it a 24hr run with memtest86 if possible, and depnding on the DIMM configuration look at testing it with half the memory fitted only and then the other half. Might show nothing useful but memtest86 at least is any easy thing to do and if it turns up errors you've nailed the problem
