Could setting the parameters wrong in BIOS settings cause SOME errors though? I'm not saying that many errors but if there were just a couple of errors. Just curious.
Again, by Default the RAM should work that is assuming you're using the correct DIMM slots.
Sure if you put some oddball aka wrong values DRAM parameters then the RAM will produce tons of errors or simply not post.
Try to Clear CMOS, unplug the PSU for 5 minutes, then follow the steps in this video -> http://www.youtube.com/watch?v=rdHH9KrceR0
