I have had continued difficulties with OCZ Platinum DDR3-1800 and system stability. I have tried all of the various recommended settings including clock skew. I just got off the phone with OCZ tech support. I can say that I am very impressed with their customer service. I am going to exchange 2 sticks of the platinum for 2 sticks of the Reapers. It sounds like these are much more compatible with this board. I'll let you know how it turns out.
