Overclocking and Temperatures
As you can see when compared to the reference design HD6850 the Sapphire TOXIC increases core speed by 45MHz and the Memory by 100MHz.
If there is one thing the Sapphire does, it's earn the TOXIC badge with aplomb. The Memory wasn't really happy going anything worth keeping above the already speedy 4400MHz, but the Core was almost indestructable.
Using the Trixx software, which we'll go over on the next page, the card hit 1056MHz before falling over. Backing off to 1026MHz ran nearly every test perfectly but eventually keeled over during Metro 2033, and so our bench runs were done using 1000MHz core.
1000MHz core ladies and gentlemen. How impressive is that?! 180MHz over the stock TOXIC, 225MHz over a stock Radeon HD6850.
After a 3D Mark Vantage Extreme run the GPU topped out at 83°C which is heading towards as comfortable as we like. But if one thing is clear it's that with serious cooling, and a willingness to push the voltage as high as you can, then it seems like the only limit to the Sapphire HD6850 TOXIC is your imagination. Or the overclocking slider.
