LAST EDITED ON Mar-13-01 AT 02:23 PM (GMT)That depends on how good the memory and motherboard are. Obviously, the default settings are conservative (like me, when it comes to computers). Good PC133 memory should be able to operate at 8 ns. I’ll leave discussion and recommendations on other settings to other readers of this forum. Be advised that changing CAS and other settings can lead to system instability and file corruption, especially in hot weather. Larry
