I will be putting together an Opteron 144 gaming system pretty soon. One of the problems I will be running into is that, although the Opteron supports dual channel memory, it requires registered memory. I will be overclocking the system so I definitely want high quality memory such as Corsair XMS. But I'm having a hard time locating registered versions. I heard not to long ago that Kingston would be releasing the HyperX series in registered versions, but I cannot find that either. Suggestions?
