yeah, 8 gigs of G-skill DDR2 800. and i have water cooling. um...... where do i change this
Use Realtemp or Coretemp to monitor your temperatures. Below 50C is optimal, below 60C is safe and above 60C is dangerous. The absolute threshold for you is 71 degrees.
Change these settings through the bios. Upping the CPU's voltage will increase stability allowing for better speeds, but also increases the temperature of the CPU. Voltage thats too high can damage your CPU regardless of the temperatures.
For a Q6600, the CPU voltage thresholds are:
Below 1.4v is completely safe
Between 1.4-1.45v is moderate but safe
1.5v is the boundary to which your CPU may experience a deceased lifespan
Don't push your North Bridge voltage above 1.4, you can leave it on automatic which will be fine if you like.
Remember, total CPU speed = Multiplier x FSB. As you have DDR2 800, your RAM has a speed of 400 (for reasons that are convoluted, just trust me). So try to set it so that your FSB is as close to 400 as possible. For example, for a 3.2ghz overlock: 8x400 is better than 9x355, though the speeds are identical. Setting your CPU's FSB higher than your RAM will mean you have to overclock your RAM, which you don't need to do. RAM can be faster than your CPU, your CPU cannot be faster than your RAM. Don't do 7x450 unless you are willing to overclock your RAM.
Expect anywhere from 3ghz to 3.6ghz depending on the quality of your chip (which is random). Tinker with speeds and voltages until your CPU is completely stable at the lowest possible voltage.
To test stability, download OCCT and run a 1 hour test. If you pass and your temperatures don't exceed 60 by too much, your CPU is stable and healthy. OCCT will push your CPU harder than anything else you would otherwise run will, if you can pass it without crashing you are fine. If your computer crashes (and if you are doing it right, it will, alot!) don't worry. Crashing because you set it too high won't hurt your CPU, only pumping insane voltages into it or letting it overheat will.
