elchorizo, For heaven sake, read the thread before you make your post.
You are running DC2T and Toxic´s! Those cards can do 1140/1800. Majority of 280x cards can not.
Besides. Those cards fans are screaming loud at 70+ %.
Of course, its possible to do 800s with proper setup. If its worth to spend so much more money and power cost on Toxic cards for gaining additional 50-60khs is another story completely.

OK Mr. Internet Expert

You may want to tell your buddy that the Dual-X is identical to the Toxic except for the fan setup. In fact, he can flash the same Toxic BIOS I'm using onto his card and it will work just fine.
And I find 2800-3000 RPM @ 72 degrees to absolutely not be "SCREAMING" as you put it.
You guys make me laugh. I won't bother wasting my time trying to help people out in this thread anymore. The information is out there if you are to lazy to find it and utilize it, thats on you. Everything I've said above has been said at litecointalk.org many times.
