i picked up one of these mobos the other day and slapped on a Q6600 and i'm having memory issues too

The system boots and runs OK, but crashes sometimes and sometimes programs run choppy with short freezes between operations (ie running a game, or loading multiple instances of internet explorer)

Was there a solution to this issue? Should I try higher bus ram? (1066 maybe?) cause i'm running everything stock right now, no overclock, nothing...and yet when I memtest, my system fails every pass, i'm going crazy here >.<
