Most users have pointed out stability issues and most have been captured and pointed out in other thread.
Depending on set-up stability can also be memory heat issues. The problem is not the memory itself but the regulators sitting on the other side of the board.
Some memory module can withstand a lot more heat before slowing down,this is where lock-up,crash happens.
Too much focus has been put on CPU,chipset cooling where its the regulators that may need cooling.
Regulator cooling is not required as long as memory can operate correctly in a hotter environment.
