ASUS Maximus III Formula (P55 Express) Motherboard - BIOS and Overclocking

ASUS has gone once again with its tab BIOS menu which they have used for some time. The layout compared to earlier boards has changed; you are greeted straight away with the Extreme Tweaker menu when you load into the BIOS rather than having to go find it.


Under Extreme Tweaker you can adjust voltages, ratios and bus clocks all in the same area.




To find the extra tweaking options you need to go to the Advanced tab. Here you can get extra CPU options and P55 chipset options along with other features.




Under the CPU Configuration menu you can tweak a few extra options. One thing we did notice is that even if you disable Speedstep technology, CPU-Z still shows it working. No matter what we did, the system would still go into speedstep mode; kind of pointless when overclocking.


Update: Post testing and obtaining our overclocking result, we learned that in order to disable Speedstep on this board we needed to also disable Turbo mode.




It's overclocking time and the ASUS Maximus III Formula managed to out clock our P7P55D Deluxe board, but still didn't come close to our GIGABYTE P55A's overclock. As mentioned, the Speedstep function was enabled. We were actually running with a 22x multiplier in Turbo mode, but because Speedstep was enabled when taking the screen capture, it reads lower multipliers.




You can see the validation here.


As all overclocking results are dependent on the hardware you use, your results may vary. Results of our overclocking tests are included in the performance section with the stock scores.


Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time of testing the motherboard. Due to time constraints we weren't able to tweak the motherboard to the absolute maximum and find the highest possible FSB, as this could take days to find properly. We do however spend at least a few hours overclocking every motherboard to try and find the highest possible overclock in that time frame. You may or may not be able to overclock higher if you spend more time tweaking or as new BIOS updates are released. "Burn-in" time might also come into play if you believe in that.
