Gigabyte G1.Sniper 3 Review
For those of you who were wondering about the lengthy delay between Z77 reviews it's all to do with the ease of obtaining a HD7970 to continue our testing. The world financial crisis hits everywhere. Thankfully Sapphire stepped in with a HD7950 which enabled us to return to the Ivy Bridge testing, so maximum kudos to them. Just worth noting when we come to the 3D tests that the GPU isn't the HD7970 that the other Z77 reviews were tested with.

With the eternal quest for more power efficiency our initial results with Z77 motherboards weren't exactly amazing, as the latest chipset seemed to require countless tweaks to remain stable at decent overclocks. Just when we thought we'd have to relearn how to overclock a LGA1155 CPU along comes the Sniper 3, which was as easy to overclock as the P67/Z68 motherboards ever were. A simple voltage boost and increase on the CPU multiplier and everything ran like clockwork. It's reassuring to know that it wasn't our ability at fault, but rather the other motherboards.
So here we have a wonderful 5GHz on air, using only 1.38v on the core. Very impressive stuff by the Sniper 3.
Of course we like to run with as little voltage as possible, especially with the reduced tolerance for high voltages on the 22nm CPUs, and so dropping down to default volts we were still able to see 4.8GHz from our i7-3770K, and that's what we'll be using for our overclock tests.
