ASUS has added the new 5-way optimization to the Ai Suite III software. This will actually tune your system and overclock it for you. After running through it, it gave us a 27% overclock on our i7-4770K up to 4.7 GHz.
While this was a good overclock, it was not exactly stable as many of our benchmarking tests caused BSOD’s. So I went ahead into the BIOS and set my own overclock down to 4.6 GHz, which turned out to be 100% stable.
