Introducing the graphics card that can overclock by 100%+

8 Pack · 30 Apr 2014 at 15:05

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!!!

and the score:

What the hell lol, Nice one.

Even with a 100% overclock the pixel rate is still only 12.7 GB

Who would've thought measly old R7 240's could achieve a 100% overclock.

£45 card running at near stock 7970 speeds - not bad at all Ian.

That power setup is completely nuts too!

That is modding madness

I'd love to see what sort of fps they could achieve in a variety of games.

Boomstick777 · 30 Apr 2014 at 15:59

That is some overclock

Nice, lol the heat that must be chucking out at that OC you could brew a cuppa up while benching.

Sam owns a 7990 i think. Or is that Thracks? Might be both of them. All the AMD guys seem to be on Tahiti. I guess they don't get the freebies i expected them to.

Wow

that looks both impressive and insane, perhaps the perfect combination :cool:

I imagine the lights in the building flickering as that beast fired up :eek:

Thanks guys!! No this rig pulls very little power. Poured such a small amount of LN2 to maintain temps on these cards.
