The HD 5970 TOXIC from Sapphire has got a bit more coverage than usual when it comes to looking at a video card; the main reason for this is that not only are there limited amounts of the model around the world, but also it's the world's fastest video card thanks to some insane stock clocks on the model.
Today we're back with the model and what we want to find out from the model is if we can overclock past what it's already very high default clocks are set at. The fact that I'm writing this article means we could get a bit of extra power from the model, otherwise I wouldn't be wasting yours and my time here.
The question is, how far did we get? - The main thing I wanted to see was a 1GHz core clock on the card. We figured we needed to play around with the voltage a little to get that. At the same time we wanted to see if we could get anything more out of the mammoth 4GB of GDDR5.
Since we already looked at the Sapphire HD 5970 TOXIC 4GB in its entirety here, if you haven't had a look at it yet I recommend you check it out. If not, it’s worth clicking on the link just to see the card itself and the bundle.
Since we've looked at the card as well, we'll just be looking at the overclocking we did quickly before getting stuck into the performance improvements we got in doing so.
