CPU: AMD FX 6300 Black Edition Vishera 6 core, 95 watt

GPU: Sapphire ITX Compact R9 285

Memory: Corsair Vengeance LP 8GB (2x4) DDR3 @ 1600 ( I couldn't find this on the support list, details below) 

PSU: EVGA NEX650G 650W

The display is my secondary monitor that I know works. It is connected via DVI.

Here are the symptoms: 

Computer starts up, lights, fans, even had USB power when I had them connected. Does not post, does not display on monitor. 

If I disconnect the graphics card, I get the 5 beep post code for a VGA error. 
If I remove the memory, I get a no memory beep code.

-I've carefully checked all of my connections, my CPU is receiving power, my CPU fan is running. The CPU has no bent pins.
-I've tried an older AMD video card, that I know works, to no avail.

-I have re-seated the memory and tried it in every slot both individually and in dual channel.

I have NOT tested the PSU yet, I haven't had the means. I do have an older, 620 watt PSU that I can cannibalize from a running system if needed. 

The reason I'm seeking a second (really third) opinion on my memory concerns is because when I contacted ASRock support and sent them the information on my build, the memory was listed. They made no mention of it being incompatible and a possible cause of my problems. I'm thinking it was just overlooked as my problem initially was that I kept on getting the VGA beep code. After re-seating my GPU several times it finally no longer through the VGA code and instead would not post clear or provide input to the monitor (attempted with both video cards). 

Sorry for the book, but more information tends to help with troubleshooting these issues. 

TL;DR : Is my memory incompatible with my mobo; and would it be causing it not to clear post or provide input to my monitor. 

Thanks for you time!
