OverKILL-3D ASUS HD7970 Quadfire Madness

Intro

Six weeks ago we did our initial test of the Quadfire beast that is our HD7970 rig. Although the results we obtained were, of course, incredible, we were disappointed that a combination of factors meant we couldn't push the boat out and overclock the cards for the ultimate numbers.

This is especially true because we know what a complete monster the HD7970 is when it's overclocked. Sure it's a fabulous card at stock, but there is so much extra performance waiting to be unlocked that we couldn't help have an itch we hadn't yet scratched.

Thanks to our friends at ASUS we've managed to revisit our old results and strike them from the record so that we can really see what ludicrous amounts of money, and no respect for the electricity meter, can do when poked with a stick.

Overclocking

Yes a combination of a BIOS update for the ASUS Rampage IV Extreme, and the always trick ASUS BIOS on the cards themselves, we've managed to push our four HD7970s to a pretty big 1225MHz.
