One final comment - CPUz shows your RAM is currently running at 2400. You can fix that f2 on startup, performance options, and XMP2 (you can also try XMP1 first). 
Just unboxed this beast from Best Buy and in getting everything running, came to this forum to read about problems. I attached CPU-Z because I read that you can not add regular HyperX memory to the R9 because of the higher voltage requirements of the Alienware brand HyperX memory.  CPU-Z shows it running at 1.2v, which is the norm. I talked to a Dell rep and they quoted me $99.00 for 1 stick of 8GB RAM and it was an off brand, not even Kingston. I search Dell myself and find 2 X 8GB @  $139.00 for the R9, much better price however, it is almost twice the cost of the same Kingston memory.
