Note that tray tools is a little buggy. I still haven't found a way to change the active GPU for overclocking settings. There is a checkbox to make all changes to both GPUs. What I do is set both cards to 940/331, then I uncheck the box and set the rate to 840/250. This leaves the second GPU at 940/331 and changes the first GPU to 840/250. Also, each time you change the clock rate it sets the fan speed back to automatic, you'll have to go change that back to 100 percent.

Got it, it's working. Thanks so much, I spent all day trying to troubleshoot this. +karma!

Okay, I'll give that a shot. Thanks!

Okay, so I'm having issues downclocking the memory on my 6970's.

I'm using MSI Afterburner, with the settings to allow for non-BIOS spec'd "Unofficial Overclocking."
I can get the program to allow me to turn the clock down as far as I want, however, as soon as the cards are under load, the memory clock returns to 1375.
I've found the lowest I can go without it resetting is 825.

I've seen people posting here that they have achieved memory clocks of ~350, but I'm not sure if that is true.
Please check your MSI Afterburner graphs and verify that the cards are indeed at 350.

I've also tried disabling AMD Overdrive, as well as modify the registry to allow non-spec'd values, nothing worked.

Any help is appreciated-these cards run hot!
