Edit: Also, this is a problem I have countered when trying to use lower latency on the sticks, then having one of my dimms fade out. (If you use AUTO this might be the problem, try set em at 9-9-9-24 and vdimm at at 1.65). My dimm fading out on low CAS were fixed by a heatsink reinstall. (One that had more proper pressure on the CPU).

Thanks for you replay, I found the problem and it s one of the Dominator is damaged so I have to RMA it back.

Thanks again
