Overclocking

Overclocking with the ASRock Z77 Extreme9 was significantly better compared to the other Intel Z77 Express products I've tested so far, with a setting of just 1.17 V in BIOS needed to bring my 3770K to stability at 4.6 GHz. Memory clocking using XMP worked flawlessly, booting right in with 2400 MHz like it was no big deal. I recorded a VRM power consumption of 99 W while running stability testing, less power draw than what I expected.

Overclocked Performance Summary

Cinebench provides a substantial performance increase when overclocked, something that resounds true through the entire series of Intel-based products. The ASRock Z77 Extreme9 wasn't the best performer, but it wasn't last, either.


SuperPi 32m results were again average for the ASRock Z77 Extreme9, which finished just 1.42 seconds faster than our worst result.


WPrime 1024M numbers further the results, again giving average overall performance.


For a bit of 3D action we fired up CodeMaster's F1 2010 to be impressed with the performance boost offered compared to the other products, with the ASRock Z77 Extreme9 managing to show an increase when overclocked in F1 2010, when quite a few others did not.


With Codemaster's F1 2010 starting to show its age, and proving less reliable in showing performance increases, we've added the Shogun 2 DirectX 9 CPU benchmark to our testing suite. Here again the ASRock Z77 Extreme9 fared pretty well, and ended up in third place.
