got that card last week, no problems with it so far, temps are at 75C, at 60-65 % fan, and not as noisy as they seam on most of reviews. clock 1080/1500...

cheers

Some further notes. Previously I had made it so it only displayed on desktop one and did not extend the displays to the other video card.  I like my cursor to stop at the borders of the screen. This seemed to further throttle the R9, which I only use for mining. By enabled the extension of the desktop to both displays, I can now get full sensor reporting and the proper speeds (760khps).

Not what I want but still working on it.

Yes, that's the one i made. I can tell it is working because when I plug in the dummy plug, the screen resolution screen in Windows shows a second desktop.  When I unplug it immediately goes away. So the plug is doing something. Unfortunately, what I am finding is that if its not plugged into the monitor the card appears to be throttled to around 550 khps. Sometimes I can squeeze more out of it, but not much. If I plug the monitor into it, it can go to 700+ like I was expecting.

Going to play with this version of the dummy plug and see if it helps:

Thanks for the tips. I switched to the beta and no joy.

I then hooked up my monitor directly to it instead of the GTX670 and it works.  now So it looks like an issue with the dummy plug I am using (made my own based on overclock instructions).  Unfortunately, I have no idea how to tell if the dummy plug is properly being detected and works as I am able to mine on the R9 regardless of whether its hooked up to a dummy/monitor.

I have the exact same issues you have. I didn't consider it could be the plug. I just have a spare DVI cable plugged into my second card, but I don't get any temperature readings in GPU-Z, and I can't change any settings in MSI Afterburner. I have an XFX R9 280x, but seem to have the exact same problem as you.

Someone linked this in another thread, I'm going to try and build one; http://www.overclock.net/t/384733/the-30-second-dummy-plug

Anyone else having an issue with getting GPU-Z or cgminer to display the temps on a Sapphire Toxic R9 280x?
