Gigabyte Z77X-UD5H Review
Starting with AIDA64 we can see that at stock there is very little difference between the Intel reference board and the UD5H. Of course the overclock gives a handy boost indeed as it really unlocks the extra power available from the 22nm chip.
The Memory scores are obviously jaw-dropping. 28GB/s is nothing to be sniffed at, even if it isn't quite the quantum leap ahead of the 2133MHz kit we tested the P8 with. It's plenty fast enough though.
