Crossfire RX 480 8GB Freezing Under Load

I know there has been issues with the new RX 480 cards with too much power draw. I am currently experiencing the following issue. I have crossfired two PowerColor Radeon RX 480 8GB cards in my PC. After numerous hours last night of troubleshooting, changing some things, removing and re-installing drivers, nothing has changed or really helped. It seems when I run a high demanding load like Heaven Benchmark or Siege Benchmark while Crossfire the computer will make a pop noise through the speakers and freeze or Ill get a blue screen of death, which I have to hard restart from the tower. I also have the Power Efficiency set to on, under the control panel for Radeon.

 

My current set up is:

ASUS M5A99FX Pro R.2 M.B. (latest BIOS drivers updated)

AMD FX-4350 4.2 GHZ Processor (Not overclocked)

Corsair TX750M - 750 Watt Power Supply

Arctic Freezer CPU Cooler

16 GB DDR3 Memory

250 GB Samsung SSD with 1 TB SATA HD

Windows 7, Service Pack 1 (recently new format install onto SSD)

Crossfire PowerColor Radeon RX 480 8GB with drivers 16.7.1

Dual Samsung 27" 1080p monitors (one using HDMI - HDMI, other D-Port - HDMI)

 

I had the PowerColor Radeon HD 7850 graphics card before and had no issues what so ever.

 

I also removed one of the cards and ran a benchmark with no problems, no freezing or anything, but as soon as I Crossfire I run into issues.

 

Please any help would be greatly appreciated, my buddy who is an IT guru is stumped as well!
