For Overclocking Pro Cup Q1 2014 that just finished today the final challenge in the set of five was to take as many R7 240 GPU and get as good a score on 3D mark 11 as possible.
I modded my R7's with 3 EVGA E- power boards per card one each for Core, Pll and Vmem.
This allowed me to take the card from 720mhz stock to 1590mhz at 1.4v with -45 on each card been the optimum temp. The cards would not scale anymore with volts but still monumental overclock.
Full system
4930K 6.2g
ASUS RIVE BE
Corsair Dom plats 2700 9-12-12-21 1T
3 x 1200w PSU needed 9 PCI X connectors per card!!! lol!!!
Here are some pics of the beasts in action!!!
