Overclocking – Auto and Manual

Auto Tuning

We went into the Auto Tuning section of the TurboV EVO in the AI Suite II software. Essentially what happens is you hit the Start button at the bottom of the screen and let TurboV EVO do its thing. It will bring up a display/progress screen that will show you the incremental overclock increases, and when the system finally becomes unstable, it will automatically reboot and finish off the previous stable sequence. This takes about 10 minutes, so it’s not a big deal, as you really show only ever need to do this once and then leave it alone if you choose to go this route.

There are two presets for Auto Tuning: Fast and Extreme. Obviously, we chose Extreme.

We let the Auto Tuning run for about 10 minutes to find fully stable clocks and ended up with the following result.

Hitting 4.85GHz on Auto Overclocking is nothing short of outstanding.

Manual Overclocking

Manual overclocking can yield slightly higher bus speeds (BCLK) but as mentioned, you won’t go much higher than the base 100 MHz. There will be some wiggle room, and playing with the voltages will extract a bit more out of the board and allow some people to hit 5.0GHz with golden chips, but with the Auto Tuning will produce extremely impressive results in a few minutes and one click of a mouse. Frankly, it may sound blasphemous to some, but ASUS may have made manual overclocking no longer necessary.

That being said, we tweaked the voltages a bit and manually overclocked the system. We fared a bit better, breaking the illustrious 5.0GHz barrier and eventually hitting 5.04GHz.

We know this particular chip really doesn’t have much more in the tank as far as multiplier goes, so the Maximus IV Extreme essentially topped out the CPU, which is very satisfying to see.
