I'm not sure if I want to go any higher. Its stable at that speed with stock voltages. The Temps only reach to a highest of 54C (that was when the room was at 27C) and when the room is at about 21-24C its highest temp is 51C.
Personally I think theres 200Mhz of speed that the ram is not using, so I what to make that a little less.
Wow, I'm stupid, I forgot that Overclocking the FSB increases the Ram speed too.
That still doesn't change the fact that I have no idea what ram timing I can change in my benefit without frying the Sticks.
