You have a PM as well. I don't think your issue is RAM, that Corsair memory is just fine. I'm not sure what your issue relates to; however I will tell you that I had a much more stable machine once I disabled the onboard SATA-3 controller. Works fine as long as I only had 1 or 2 drives in their, but once I had drives on both SATA controllers nothing but random lockups. I have all my SATA 3 drives on my ATTO card and it's much more stable now.
