Yeah, Samsung is really kick-ass. I tried the Kingston Hyper-X...gay. So many errors, then ultimately system stalled. Switched to slower (7-3-3-2.5) Samsung...happy. Samsung is still THE #1 stable\overclock capabel memory. Yesterday overclocked my fsb (i got 2700 modules) from 166 to 200, just to see how it goes. It went awesome. Not a glitch of instability. Go Samsung!
