This looks like a hardware memory error and the only fix is to replace the failing memory stick. How many memory modules are installed and what size and speed are they rated for? For instance, on my main system I have 16 GB total RAM memory, made up of (4) 4 GB memory modules and rated for DDR3 1600. In my PC setup if I saw your error message, I would assume the memory socket for the second memory module was bad, but I would have to pull both modules out (0 & 1) as it works in dual channel mode, leaving in just modules 2 & 3, counting from zero, which uses two memory modules at a time. I would then see if I got the same problem, assuming it happens often enough to find out for sure I have fixed the issue.
