    What is Independent Channel Mode?


      In the Intel Server Board S1200BT Service Guide on page 14, there is a paragraph, in the Memory section that reads:


      The Independent Channel Mode is the default Maximum Performance Mode preferred for Intel Xeon Processor E3-1200 Series based platforms.  All two channels may be populated in any order and have no matching requirements.  All channels must run at the same interface frequency, but individual channels may run at different DIMM timings (RAS latency, CAS latency, and so on).


      I'm trying to determine why I'm getting unstable memory performance when I have 2 DIMMs installed, but not when I have 1 single one.  Each one can run independently in slot DIMM_A1 but if I try to use two of them in DIMM_A1 and DIMM_B2, I get kernel panics after about four days of operation.  Memtest86+ shows no errors after days of operating also.

      But from what I read in the manual apparently it doesn't matter what memory slots I use at all.  I'm using a Xeon E3-1265L V2 cpu.


      So is Independent Channel Mode *not* Dual Channel Symmetric?  Does this paragraph mean I ignore table 4 completely, which shows which order to populate the DIMMs?
