Overclocking

Frankly with the Toxic, the overclock that comes with the card is better than I would expect to run on most cards. So the way I looked at getting even more out of the Toxic is everything else is a bonus. Even still I went into this like any other card, starting with the GPU overclock and then going into the memory overclock. With the GPU overclock I started at 1200MHz and had good luck. After that my next run at 1300MHz failed meaning our end result would be in between the two. In the end I was only able to get 1225MHz, a respectable number but it does make it obvious that Sapphire had already pushed the card fairly far. This is the exact same number that I got out of the Asus 280X as well.

Memory overclocking didn’t go as smoothly. I started at 1800MHz and struggled to get past that at all. In the end I was able to edge in 1825MHz. That ends up being a clock speed of 7300MHz but that is still a tad lower than the Asus card. I did run the memory overclock together with the GPU clock from before with no crashes or issues.
