Typically we don't even entertain the idea of overclocking these kinds of graphics cards, but given how cool the R9 295X2 runs we decided to give it a shot. As expected, the results weren't that exciting, as we managed to push the cores 7% higher to 1085MHz. The GDDR5 memory was willing to play ball but without a significant boost in core clock speed the gains here would go unnoticed. Still, the memory reached 1500MHz, a 20% increase.
Here we see just 2fps more from our overclock in Battlefield 4 at 2560x1600.
The gains in Crysis 3 were minimal, just 1fps extra from the custom overclock.
Finally, we received a 4fps gain in Tomb Raider, which wasn't enough to beat the GeForce GTX 780 SLI configuration.
