What we're really interested in seeing today is the performance of the ASUS Maximus VI Impact against other Z87 Mini-ITX motherboards we've looked at recently. Two of those said boards are the MSI Z87I and GIGABYTE Z87N-WIFI. Along with those two Mini-ITX boards, we've also got the GIAGBYTE Z87X-OC, MSI Z77A-GD65 Gaming and GIGBYTE X79S-UP5-WIFI to round off the collection today.
As always, before we get into the performance of the board, we check in and investigate overclocking. While no board has yet been able to give us 5GHz stable on our CPU, we always like to try it. With everything setup, we got into Windows at 5GHz with no problem. This isn't the first board to do this and getting into Windows isn't the biggest surprise. Although, we must admit a certain amount of shock when it fires straight up on a Mini-ITX motherboard.
Once in Windows, we fired up MediaEspresso to see if the CPU clock was stable. With little surprise, our system froze up fairly quickly. Heading back into the BIOS, we moved to the 49x Multiplier, which resulted in our CPU running at 4.9GHz. We headed back into Windows again, fired up MediaEspresso and completed it with no issue.
With everything looking good at 4.9GHz, we headed back into the BIOS to see if we could do a bit of BCLK fine tuning. To date, though, this has not been possible. Again this was a problem we ran into here and in the end you can see we ended up with a final clock speed of 4900.1MHz or 4.9GHz.
